VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2018147873
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance workability even in the case where an optical member can rotate with respect to a housing, in a vehicular lighting fixture which is constituted so as to perform light distribution control on the light from a light source by the optical member.SOLUTION: An optical axis adjusting screw 40 for rotating an optical member 30 around a rotation axis line Ax1 extending in a vehicle width direction is supported by a lamp body 12 in a state of extending vertically. On a left end part of the optical member 30, a projection piece 34B extending toward the rear side of a lighting fixture is formed, and on an inside surface of a rear part region 34Ba positioned further on the rear side of the lighting fixture than the rotation axis line Ax1 of the projection piece 34B, a groove part 34Ba1 screwed with the optical axis adjusting screw 40 is formed. Also, at the lamp body 12, a fall-off prevention part 12b2 for preventing the groove part 34Ba1 of the projection piece 34B from falling from a screwed state with a screw part 40a of the optical axis adjusting screw 40 is formed in a positional relationship of approaching an outside surface of the rear part region 34Ba of the projection piece 34B.SELECTED DRAWING: Figure 1
