Abstract
A vehicular headlamp having an inclination measuring unit mounted on portions of an aiming screw which extends rearward from reference member. The inclination measuring unit is interposed between a reference member and the rear end portion of the aiming screw, protruding rearward from the reference member. The inclination measuring unit includes a cylindrical transparent casing surrounding the aiming screw and fixed at one end to the reference member, a cylindrical base accommodated in the transparent casing in such a manner as to be rotatable when the aiming screw is turned, a ring-shaped slide member engaged threadably with a male-threaded outer cylindrical wall of the cylindrical base, the slide member being slid axially by rotation of the cylindrical base while being prevented from being turned relative to the transparent casing, a coupling member extending through an opening formed in the transparent casing into the cylindrical base to engage with tapered engaging portions of the cylindrical base and with outside surfaces of the aiming screw to couple the aiming screw with the cylindrical base, and a scale formed on the transparent casing and a reference line formed on said slide member to indicate the amount of relative displacement of the inclination member. With the invention, unlike the prior art, it is not necessary to provide a fine adjustment mechanism for adjusting the scale following initial zero-point adjustment.
