Abstract

A disc brake caliper includes an outer body, an inner body, and joining parts connecting the inner body and the outer body with each other at both end portions in a circumferential direction of a rotor so as to form an opening part. An inward end edge of both end edges in the circumferential direction of at least one of the joining parts, which defines an end part of the opening part in the circumferential direction, is inclined relative to an axial direction of the rotor towards a central part in the circumferential direction of the outer body from the inner body side to the outer body side, so that a length of the opening part in the circumferential direction is shortened from the inner body side to the outer body side.

Claims

1. A disc brake caliper, comprising;

an outer body, provided to be opposed to an outer side surface of a rotor configured to be rotated with a vehicle wheel, and including an outer cylinder which is opened towards the outer side surface;

an inner body, provided to be opposed to an inner side surface of the rotor, and including an inner cylinder which is opened towards the inner side surface; and

joining parts, provided outside of the rotor in a radial direction of the rotor, and connecting the inner body and the outer body with each other at both end portions in a circumferential direction of the rotor so as to form an opening part which is penetrated in the radial direction between the joints parts,

wherein an inward end edge of both end edges in the circumferential direction of at least one of the joining parts, which defines an end part of the opening part in the circumferential direction, is inclined relative to an axial direction of the rotor towards a central part in the circumferential direction of the outer body from the inner body side to the outer body side, so that a length of the opening part in the circumferential direction is shortened from the inner body side to the outer body side.

2. The disc brake caliper according to claim 1,

wherein both end surfaces of the outer body in the circumferential direction are inclined surfaces that are inclined towards the central part in the circumferential direction from the inner body side to the outer body side, so that a length of the outer body in the circumferential direction is shortened towards an outer end surface of the outer body.

3. The disc brake caliper according to the claim 1,

wherein a central part in the circumferential direction of the inner body and a central part in the circumferential direction of the outer body are connected by a middle joining part at an outside portion in the radial direction, so that the opening part is divided into two parts in the circumferential direction.

4. The disc brake caliper according to the claim 1,

wherein the inward end edge which defines the end part of the opening part in the circumferential direction is inclined 10 to 30 degrees.

5. The disc brake caliper according to the claim 1,

wherein a pair of inward end edges of the joining parts, which define both end parts of the opening part in the circumferential direction, are inclined the same degrees relative to the axial direction.

6. The disc brake caliper according to the claim 1,

wherein a pair of inward end edges of the joining parts define both end parts of the opening part in the circumferential direction, and

only one of the inward end edges at a trailing side of the rotor while a vehicle advances is inclined relative to the axial direction.

7. The disc brake caliper according to the claim 1,

wherein a pair of inward end edges of the joining parts, which define both end parts of the opening part in the circumferential direction, have different inclination angles relative to the axial direction from each other.
