Abstract

The present invention relates to a vehicle lamp. An object of the present invention is to improve the reliability of an operation unit that performs illumination adjustment of a lamp and to improve the operability of the operation unit. The vehicle lamp includes an operation unit (6) for operating a bevel gear (50) for adjusting the optical axis of the lamp (1) in a shaft driving manner. A shaft driving force transmitting body (7) of the operation unit (6) includes an operating lever (71) for shaft driving operation, a driving rod (72) that meshes with the bevel gear (50), and a metal wire (73) that connects the operating lever (71) and the driving rod (72) in the shaft driving direction, and the driving rod (72) is formed of a metal that is difficult to rust. The driving rod is formed bya metal injection molding process. A support member (84) extends between the driving rod (72) and the lamp.

Description

technical field [0001] The present invention relates to a lamp for a vehicle, in particular to a lamp for a vehicle provided with an operating unit for adjusting and operating a beam adjustment (optical axis adjustment) mechanism at other positions. Background technique [0002] Headlights (headlights) of vehicles such as automobiles are provided with a beam adjustment mechanism for adjusting a light axis to a predetermined angular direction in front of the automobile. As the dimmer adjustment mechanism, generally, a structure is adopted to operate a dimmer screw provided in the lamp housing, for example, to screw the dimmer screw into at least a part of the lamp unit built in the lamp housing. By operating the dimmer screw on the outside of the lamp unit to drive its axis, the screwed part of the lamp unit is advanced along the axial direction of the dimmer screw, and the tilt angle of the lamp unit in the up-down direction and left-right direction is adjusted due to the mo...
