Abstract
A light source unit provided with a light-emitting element as a light source is attached to a rear wall section of a housing. The light source unit is attached to the housing, in the state where a socket is inserted in an opening formed in the rear wall section and an elastic seal member attached to the front end of the socket is pressed against the rear wall section. A rib extending toward a lamp rear side so as to surround at least the upper half section of the opening is formed on the rear wall section of the housing.
Claims18
A vehicle lamp comprising:
- a light source unit which includes a light emitting element, a board where the light emitting element is mounted, a socket configured to support the board, and an elastic seal member mounted on a front end portion of the socket;
- a projection lens configured to control light distribution of light from the light emitting element;
- a lens holder configured to support the projection lens;
- and
- a housing configured to support the lens holder such that the lens holder is rotatable around a rotation axis extending in a vehicle width direction,
- wherein the light source unit is mounted to the housing in a state where the socket is inserted into an opening formed in a rear wall portion of the housing while the elastic seal member is pressed against the rear wall portion, and
- wherein a rib which extends toward a lamp rear side is formed on the rear wall portion of the housing so as to surround at least an upper half portion of the opening.

A vehicle lamp comprising:
- a projection lens configured to control light distribution of light from a light source;
- a lens holder configured to support the projection lens;
- a housing configured to support the lens holder such that the lens holder is rotatable around a rotation axis extending in a vehicle width direction;
- and
- a translucent cover supported by the housing,
- wherein an air hole is formed in a peripheral wall portion of the housing so as to absorb pressure fluctuation in a lamp chamber formed by the housing and the translucent cover,
- wherein the air hole is formed in a side wall portion on a vehicle width direction inner side of the housing,
- wherein the lens holder includes a pair of left and right fulcrum protruding portions formed at positions on the rotation axis,
- wherein the housing includes a pair of left and right fulcrum engagement portions which are formed at positions on the rotation axis on left and right side wall portions thereof and configured to engage with the pair of left and right fulcrum protruding portions, and
- wherein the fulcrum engagement portion formed on a side wall portion located on the vehicle width direction inner side among the left and right side wall portions is configured as a fulcrum engagement hole which penetrates the side wall portion in the vehicle width direction.
