Abstract
A vehicular lighting fixture is provided which includes a combination of an aiming mechanism and a leveling mechanism that can reduce deformation of an aiming/leveling bracket. A vertical aiming mechanism and a leveling mechanism include an aiming/leveling bracket that is integrally molded with a resin. A rectangular recess is formed in the aiming/leveling bracket so as to accommodate an aiming nut serving as a point of load for the vertical aiming and an actuator output shaft serving as a point of effort. The rectangular recess is located on or near the central axis of the aiming nut where the central axis substantially coincides with the front-rear direction of a vehicle.
Claims20
A vehicular lighting fixture comprising:
- a housing;
- a lamp unit, accommodated in the housing and configured to emit light in a front direction;
- an aiming mechanism, accommodated in the housing and configured to enable aim of the lamp unit in a vertical direction or a horizontal direction of a vehicle when the vehicular lighting fixture is mounted on the vehicle;
- and
- a leveling mechanism, accommodated in the housing and configured to level the lamp unit in the vertical direction or the horizontal direction of the vehicle independently of the aiming mechanism, wherein the lamp unit is supported by the aiming mechanism and the leveling mechanism, and wherein:
- the aiming mechanism includes an aiming bolt and an aiming nut configured to be screwed onto the aiming bolt;
- the leveling mechanism includes a leveling actuator and an actuator output shaft protruding from the leveling actuator and which is movable by the leveling actuator;
- the aiming mechanism and the leveling mechanism include a shared aiming/leveling bracket integrally molded with a resin;
- the aiming nut is formed in the aiming/leveling bracket;
- a recess configured to accommodate the actuator output shaft is located on or near a central axis of the aiming nut of the aiming/leveling bracket;
- and
- the aiming/leveling bracket includes left and right built-in spring slit structures which are disposed on left and right sides of the recess and via which the aiming/leveling bracket is secured to the housing.
