Abstract

Provided is a vehicle lamp including an operation unit configured to operate an optical axis adjustment bevel gear provided in a lamp to be axially rotated. An axial rotation force transfer body of the operation unit includes an operation rod operated to be axially rotated, a driving rod engaged with the gear, and a wire interconnecting the operation rod and the driving rod in an axial rotation direction, and the driving rod is formed of a metal which is hard to rust. The driving rod is formed by a metal/injection/molding (MIM) technique. A support member extends between the driving rod and the lamp.

First claim

What is claimed is:

1. A vehicle lamp comprising:
an operation unit configured to operate an optical axis adjustment gear provided in the vehicle lamp to be axially rotated,
wherein the operation unit includes an operation rod operated to be axially rotated, a driving rod engaged with the gear, and a wire interconnecting the operation rod and the driving rod in an axial rotation direction, and the driving rod is formed of a metal which is hard to rust, and
the operation unit includes a wear-resistant support member interposed between the driving rod and the vehicle lamp.

2. The vehicle lamp of claim 1 , wherein the driving rod is a molded product formed by a metal/injection/molding (MIM) technique.

3. The vehicle lamp of claim 2 , wherein the wire is formed of a metal which is hard to rust.

4. The vehicle lamp of claim 2 , wherein the operation unit includes a case covering the operation rod, the driving rod, and the wire, the case is fixedly supported to the vehicle lamp at least in each position covering the operation rod and the driving rod, and the operation rod is fixedly supported by a configuration where the case is attachable/detachable with respect to a holder provided in the vehicle lamp.

5. The vehicle lamp of claim 4 , wherein the case and the holder are configured such that a hook provided in one of the case and the holder and an engagement hole formed in the other are engaged with or disengaged from each other.

6. The vehicle lamp of claim 4 , wherein the holder is plural.

7. The vehicle lamp of claim 1 , wherein the wire is formed of a metal which is hard to rust.

8. The vehicle lamp of claim 1 , wherein the metal includes a stainless steel.

9. The vehicle lamp of claim 1 , wherein the wear-resistant support member is in elastic contact with the vehicle lamp.

10. The vehicle lamp of claim 1 , wherein the operation rod is made of a resin.
