Abstract: A lighting fixture for automobile use that includes a cylindrical surrounding wall arranged around an electric bulb at the rear of the lamp body, the cylindrical surrounding wall being engaged with the socket cover and having a plurality of slits arranged along an inner ledge or outer edge of the surrounding wall. The lighting fixture further including a plurality of engaging edges protruding from a body engaging portion formed on the socket cover, and a plurality of engaging claws formed in the body engaging portion.

Abstract: In a vehicular lamp with a waterproof cover, a cylindrical upright wall extends along the circumferential edge of the opening of the lamp body into which a bulb socket supported by the reflector is inserted. The waterproof cover for waterproofing the opening is made of a watertight elastic material. The inner portion of the waterproof cover is in close contact with the circumferential surface of the reflector or a bulb socket. The outer portion of the waterproof cover is fitted to the upright wall in a state such that the upright wall is sandwiched by the outer portion.

Abstract: A vehicular lamp having a socket cover which waterproofs a rear opening edge of a lamp body and a bulb socket or a base of a bulb attached to a reflector. A skirt fitted around a rear opening edge of a lighting fixture, and a sleeve fitted around a bulb socket or a base of a bulb projecting to the rear of the reflector are joined via a thin member. An engagement edge is coaxially formed along the inside of the skirt. A stopper flange is formed along the leading end of the engagement edge meshing with a stopper flange formed along the rear opening edge of the lamp body. A number of grooves are circumferentially formed extending parallel to each other along the inner surface of the skirt and the sleeve. Water entering from the rear opening edge of the lamp body is stopped by a recessed groove formed at the bottom between the skirt and the engagement edge and the grooves circumferentially formed along the inner surface of the skirt and the sleeve.

Abstract: A ventilation system for a vehicular lamp including a communication hole formed in the vehicular lamp; a first peripheral wall projecting from a rear surface of the lamp at a position where said first peripheral wall surrounds said communication hole; an upper and lower water preventive walls projecting from said first peripheral wall downwardly of said communication hole; a second peripheral wall surrounding said first peripheral wall, said second peripheral wall projecting from the rear surface of the lamp; a lid member engaging with said second peripheral wall for covering said first and second peripheral walls; a first space defined between the lamp, said lid member and said first peripheral wall, said first space communicating through said communication hole with the lamp chamber; a second space defined between the lamp, said lid member and said upper and lower water preventive walls, said second space communicating with said first space through a first communication passage formed at a first position in

Abstract: Art automobile headlamp having a displacement gauge that facilitates the rotation of a zeroing adjustment screw. The displacement gauge is mounted between a lamp body and a reflector, which is supported rotatably by aiming mechanisms in the lamp body and is employed to measure the amount of rightward or leftward displacement of the light beam axis of the reflector. A zeroing adjustment screw for the displacement gauge passes through and extends rearward beyond the lamp body. A crown gear, employed as a screwdriver engaging fitting to rotate the zeroing adjustment screw, is fitted over the end of the zeroing adjustment screw at the rear of the lamp body. With this arrangement, a screwdriver can be inserted from above the lamp body to engage the crown gear and to rotate the zeroing adjustment screw. In an alternate embodiment, a drive shaft is provided having a bevel gear at its lower end engaging the crown gear and a screwdriver-engaging fitting at its upper end.

Abstract: An aerodynamic vehicle headlamp having a lens cover of increased strength with no increased thickness and no reinforcing ribs. The headlamp includes a lamp housing, a reflector mounted in the housing, a projecting lens provided in front of the reflector near the light gathering region thereof, and a transparent lens cover sloping forward and disposed in front of the projecting lens and lying across the optical axis of the reflector and covering the front opening of the lamp housing. The lens cover has a curved portion corresponding to the effective light distribution region defined by the projecting lens and an annular wall extending from the surface of the lens cover, with the curved portion being surrounded by the annular wall.
