Abstract

Stepping force can be transmitted effectively from a pad member to an arm member even when a stepping operation by the foot of an operator is performed at a position shifted in a lateral direction from the center position of the pad member in the lateral direction. The body of a brake pedal (20) that is a pedal for vehicle is formed of an arm member (21) rotatable vertically about a center shaft arranged in a proximal end portion (21A), and a pad member (22) to which a stepping operation by the foot of an operator is performed is attached to an end face (21C) of a distal end (21B) of the arm member (21). The arm member (21) is made of a pipe, and an end face (21C) of the arm member (21) to which the pad member (22) is attached has a laterally long shape.

Claims

1. A pedal for vehicle comprising an arm member vertically rotatable about a center shaft arranged in a proximal end portion and a pad member attached to an end face of a distal end of the arm member, the arm member being made of a pipe,

wherein the end face to which the pad member is attached has a laterally long shape.

2. The pedal for vehicle according to claim 1, wherein a center position of the end face in a lateral direction matches or substantially matches a center position of the pad member in the lateral direction.

3. The pedal for vehicle according to claim 1, wherein a gap is provided between a part of an entire circumference of the end face and the pad member.

4. The pedal for vehicle according to claim 3, wherein the gap is provided between a lower side portion of the entire circumference of the end face and a portion of the pad member that faces the lower side portion.

5. The pedal for vehicle according to claim 3, wherein the gap is provided by cutting a part of the entire circumference of the end face.

6. The pedal for vehicle according to claim 5, wherein cutting of the part of the entire circumference of the end face is performed when the arm member is produced by cutting a material for arm member.

7. The pedal for vehicle according to claim 3, wherein a recessed portion recessed toward a side opposite to the arm member is formed in the pad member, and the gap is formed by the recessed portion by arranging the part of the entire circumference of the end face in the recessed portion.

8. The pedal for vehicle according to claim 7, wherein a protruding portion protruding toward a side of the arm member is formed on the pad member, the recessed portion being a portion recessed toward the side opposite to the arm member with respect to the protruding portion, and a portion excluding the part of the entire circumference of the end face is coupled to the protruding portion.

9. The pedal for vehicle according to claim 8, wherein the pad member is formed by press forming a plate material, and the protruding portion is a reinforcement portion of the pad member.

10. The pedal for vehicle according to claim 1, wherein a shape of a cross section orthogonal to an axis of the arm member in the proximal end portion of the arm member is a shape elongated in a direction orthogonal to a lateral direction.

11. The pedal for vehicle according to claim 1, wherein the arm member has an offset amount of offsetting a position of the distal end in a lateral direction from a position of the proximal end portion, a middle portion between the proximal end portion and the distal end of the arm member is inserted in a coupling member having a substantially C shape provided on an end portion of a rod and is coupled to the coupling member, the arm member has a projecting portion projecting from the coupling member in a cross section orthogonal to an axis of the arm member in the middle portion, and the projecting portion has a dimension in the lateral direction larger than a portion of the arm member inserted in the coupling member.

12. The pedal for vehicle according to claim 1, wherein a portion of an entire length of the arm member including at least the distal end is a curved portion projecting in a curved manner to a side of an operator, the curved portion is formed by providing a plurality of curved shape portions having different radii of curvature in a length direction of the arm member, and the radius of curvature of a curved shape portion in a vicinity of the distal end including the distal end is smallest among the respective radii of curvature of the plurality of curved shape portions.

13. The pedal for vehicle according to claim 1, wherein the arm member has a flat outer face portion that is a flat face, and a bracket to which an end portion of a return spring is coupled is coupled to the flat outer face portion.

14. The pedal for vehicle according to claim 1, wherein the arm member is made of a seam welded pipe in which a seam welded portion exists at one position in a circumferential direction of the arm member.

15. The pedal for vehicle according to claim 14, wherein a position of the seam welded portion is a position excluding a position in a direction orthogonal to a lateral direction in a cross section orthogonal to an axis of the arm member.

16. The pedal for vehicle according to claim 15, wherein the position of the seam welded portion is a position on a lateral side or a position close to this position in the cross section orthogonal to the axis of the arm member.

17. The pedal for vehicle according to claim 14, wherein a coupling member arranged crossing the seam welded portion is coupled to the arm member, and a coupling portion of the coupling member and the arm member exists on both sides of the seam welded portion.

18. The pedal for vehicle according to claim 17, wherein the coupling member is a pipe member in which the center shaft is inserted.

19. The pedal for vehicle according to claim 17, wherein the coupling member is a bracket to which an end portion of a return spring is coupled.

20. The pedal for vehicle according to claim 14, wherein the arm member is formed by performing a process of bending in a vertical direction or a substantially vertical direction a material for arm member made of a seam welded pipe, in which a seam welded portion exists at one position in a circumferential direction, and the position of the seam welded portion is a position on a lateral side or a position close to this position in the cross section orthogonal to the axis of the material for arm member in a portion of the material for arm member to be bent.

21. The pedal for vehicle according to claim 1, wherein a middle portion between the proximal end portion and the distal end of the arm member is inserted in a coupling member having a substantially C shape provided on an end portion of a rod, a bush member is penetrated through and fixed in the middle portion, a pin coupling the arm member and the coupling member is inserted in the bush member, and depressed portions having a ring shape depressed in an outside diameter direction are formed in both end portions in a length direction of the bush member in an inner face of the bush member facing the pin.

22. The pedal for vehicle according to claim 1, wherein the pedal for vehicle is a brake pedal.
