Abstract

The present invention relates to lamps for vehicles. An object of the present invention is to improve the reliability of an operation unit for performing dimmer adjustment of a lamp, and to improve the operability of the operation unit. The vehicle lamp includes an operating unit (6) for shaft-driven operation of a bevel gear (50) provided on the lamp (1) for adjusting the optical axis, and the shaft-driving force transmission body (7) of the operating unit (6) includes a shaft The operating rod (71) for driving operation, the driving rod (72) meshed with the bevel gear (50), and the metal wire (73) connecting the operating rod (71) and the driving rod (72) in the shaft driving direction, the driving rod ( 72) Formed with a metal that is hard to rust. The drive rod is formed by metal injection molding. A support member (84) extends between the drive rod (72) and the light fixture.

Description

technical field [0001] The present invention relates to a vehicular lamp, in particular to a vehicular lamp provided with an operation unit for adjusting and operating a light adjustment (optical axis adjustment) mechanism at another position. Background technique [0002] A headlight (headlight) of a vehicle such as an automobile is provided with a light adjustment mechanism for adjusting the light axis to a predetermined angular direction in front of the automobile. As the light correction adjustment mechanism, generally, a light correction screw provided in the lamp housing is operated, for example, the light correction screw is screwed with at least a part of the lamp unit built in the lamp housing. By operating the light adjustment screw outside the lamp unit, the shaft is driven, so that the screwed part of the lamp unit is fed along the axial direction of the light adjustment screw, and the tilt angle of the lamp unit in the up-down and left-right directions is adjust...
