LAMP DEVICE FOR VEHICLE AND LIGHTING DEVICE FOR VEHICLE

摘要

An adjustment mechanism configured to adjust a reference position of an optical axis of a projection lens of a lens unit has a reference axis perpendicular to the optical axis and disposed in a plane which intersects with a focal point of the projection lens. The lens unit moves in an extension direction of the reference axis in accordance with rotation of a second screw. An acting point of a force to move the lens unit is disposed in a plane formed by the optical axis and the reference axis.

主权项

1. A lamp to be mounted on a vehicle, the lamp comprising:
a light source; a lens unit including a projection lens which is disposed such that at least a portion of light emitted from the light source passes therethrough, and a holder which supports the projection lens; and an adjustment mechanism configured to adjust a reference position of an optical axis of the projection lens, wherein the adjustment mechanism includes:
a reference axis perpendicular to the optical axis and disposed in a plane which intersects with a focal point of the projection lens;a first screw configured to adjust the reference position in a first direction;a second screw configured to adjust the reference position in a second direction intersecting with the first direction;a first transmission mechanism configured to rotate the lens unit about the reference axis in accordance with rotation of the first screw; anda second transmission mechanism configured to move at least a portion of the lens unit in an extension direction of the reference axis in accordance with rotation of the second screw, and wherein an acting point of a force by the second transmission mechanism to move the optical axis is disposed in a plane formed by the optical axis and the reference axis.
