摘要:
An aiming level device for a motor vehicle headlamp which has a short longitudinal length, requires a small number of components, and is simple to assemble. The inventive aiming level device includes a body member or base, a bubble vial supporting frame pivotable with respect to the body member, and a zero-point adjusting screw for holding a sideward extending part of the supporting frame. The bubble vial supporting frame, which is formed by cutting and bending a single thin metal plate, holds the bubble vial with parts continuously formed at a side region of the front-rear extending region of the frame to support the bubble vial at front and rear portions thereof, and the front and rear end portions of the front-rear extending region are held by the zero-point adjusting screw so that it is adjustable upward and downward by rotating the screw.

A vehicular headlamp assembly with a tilt measuring device of small height, which is difficult to damage, requires a decreased number of parts, and is easy to assemble. The tilt measuring device is interposed between a protruding portion of a horizontal aiming screw protruding rearward of a reference member and the reference member. The tilt measuring device includes a fixed holder fixed to the reference member and covering the protruding portion of the horizontal aiming screw protruding rearward of the reference member, an elongated groove being formed in said fixed holder extending parallel to the horizontal aiming screw. A slidable nut member is received in the fixed holder in such a manner as to be longitudinally slidable relative to the fixed holder. The nut member threadedly engages the protruding portion of the horizontal aiming screw. A portion of the nut member is exposed through the elongated groove of the fixed holder. A scale cooperates with the portion of the nut member exposed through the elongated groove for indicating the amount of displacement of the nut member relative to the fixed holder.

A headlight for a motor vehicle having a level for adjusting the direction of light emission from the headlight in the vertical direction in which the quantities of heat transmitted to the respective regions of the casing of the level which face the bubble vial of the level are made substantially equal to each other, even if the temperature around the level changes due to the lighting or extinction of the bulb of the headlight or the like, so that the accuracy of the measurement performed with the level is maintained despite changes in the temperature around the level.

A headlight for a motor vehicle incorporation devices for measuring the amount of deviation of the beam of light produced thereby from the desired axis. The first deviation measuring device, which is used for measuring the amount of deviation of the beam in the horizontal direction, includes a calibrated rod extending between either the reflector and the headlight body, in the case of a movable reflector type headlight, or between the vehicle body and the headlight body, in the case of a movable unit type headlight. The second deviation measuring device, which is used for measuring the amount of deviation in the vertical direction, includes a level secured to the reflector or headlight body.

A mounting device for mounting a replaceable lamp assembly having a flanged plug portion on a reflector enclosure. A generally tubular mounting tube is integrally projecting rearwards of the enclosure for receiving the lamp assembly and has a plurality of radially outwardly extending and circumferentially spaced projections on the rear end. An annular retaining ring having a radially inwardly extending retaining rim for abutting with the rear surface of a flange of the flanged plug portion of the lamp assembly, and a plurality of circumferentially spaced and radially inwardly projecting engaging rims to engage with the front surface of the projections on the mounting tube when the retaining ring is fitted on the mounting tube from the rear end and is rotated relative to the mounting tube.
