Abstract

The present invention provides a steering apparatus for a vehicle, the apparatus including: a plate bracket supported on distance brackets and having a first slot through which an adjustment bolt passes, the distance brackets being coupled to the outer circumferential surface of an upper tube to face each other; a stationary gear coupled to the plate bracket, wherein the stationary gear has a second slot that corresponds to the first slot and through which the adjustment bolt passes and first gear teeth formed at opposite edges thereof; and a movable gear having a through-hole through which adjustment bolt passes and second gear teeth formed on opposite sides thereof and engaged with the first gear teeth.

Claims

1. A steering apparatus for a vehicle, the apparatus comprising:

a plate bracket supported on distance brackets, which are coupled to an outer circumferential surface of an upper tube to face each other, and having a first slot through which an adjustment bolt passes, wherein the plate bracket has an open upper side;

a stationary gear coupled to the plate bracket, wherein the stationary gear has a second slot that corresponds to the first slot and through which the adjustment bolt passes and first gear teeth formed at opposite edges thereof; and

a movable gear having a through-hole through which the adjustment bolt passes and second gear teeth formed on opposite sides thereof and engaged with the first gear teeth,

wherein the first gear teeth are configured to be resiliently bent by a clamping force of an adjustment lever.

2. The steering apparatus of claim 1, wherein the movable gear has a guide part that protrudes from a body part thereof and is inserted into the first and second slots to slide along the first and second slots.

3. The steering apparatus of claim 2, wherein the through-hole is formed through the central portion of the guide part, and the adjustment bolt is coupled through the through-hole.

4. The steering apparatus of claim 3, wherein the movable gear has gear-formed parts on opposite sides of the guide part, the gear-formed parts protruding in the same direction as the guide part, and the stationary gear is received in the space between the guide part and the gear-formed parts.

5. The steering apparatus of claim 4, wherein the movable gear has the second gear teeth formed on the insides of the gear-formed parts in the direction parallel to the first gear teeth.

6. The steering apparatus of claim 4, wherein end portions of the gear-formed parts of the movable gear are supported on the outside of the plate bracket while locking.

7. The steering apparatus of claim 4, wherein a first step is formed on the inside of the through-hole of the guide part, a second step is formed on the outside of the distance bracket, and a resilient member is coupled between the first step and the second step.

8. The steering apparatus of claim 1, wherein the plate bracket has a protruding surface that protrudes outward in a stepwise manner from a contact surface making contact with the distance bracket, and the first slot is formed through the protruding surface.

9. The steering apparatus of claim 8, wherein the protruding surface has one of a protrusion and a coupling hole, the stationary gear has the other, and the protrusion and the coupling hole are coupled with each other.

10. The steering apparatus of claim 8, wherein the stationary gear is brought into close contact with the protruding surface, and the first gear teeth extend beyond opposite ends of the protruding surface.

11. The steering apparatus of claim 1, wherein the plate bracket has cutaway portions formed on opposite sides of the first slot in the lengthwise direction of the first slot.

12. The steering apparatus of claim 11, wherein the movable gear has a guide part that protrudes from a body part thereof and is inserted into the first and second slots to slide along the first and second slots.

13. The steering apparatus of claim 12, wherein the through-hole is formed through the central portion of the guide part, and the adjustment bolt is coupled through the through-hole.

14. The steering apparatus of claim 13, wherein the movable gear has gear-formed parts on opposite sides of the guide part, the gear-formed parts protruding in the same direction as the guide part, and the stationary gear is received in the space between the guide part and the gear-formed parts.

15. The steering apparatus of claim 14, wherein the movable gear has the second gear teeth formed on the insides of the gear-formed parts in the direction parallel to the first gear teeth.

16. The steering apparatus of claim 11, wherein the stationary gear is formed such that the second gear teeth are located above the cutaway portions.
