ABSTRACT:
A vehicular headlamp having an aiming leveling device in which a support table is formed so as to project from a reflector which is tiltable relatively to a lamp body, and a bubble tube support frame supporting a linear bubble tube is provided in such a manner that one end of the support frame is fixed to the support table while the other end of the support frame is held by a zero point adjusting means used to adjust the position of the other end of the support frame in the up/down direction, with the support frame extending substantially parallel to an optical axis, and with the quantity of tilting of the reflector in the up/down direction being indicated by the bubble tube. The zero point adjusting means is constituted by a leaf-spring-like bubble tube support frame formed by cutting and bending a metal sheet, a tapped hole provided in the bubble tube support frame and extending in the up/down direction, and a zero point adjustment screw screwed into the tapped hole while penetrating the bubble tube support frame in the up/down direction and with the butt end surface of the zero point adjustment screw pressed against a screw-contact surface of a reflector. The inclination of the bubble tube support frame (linear bubble tube) can be adjusted by rotating the zero point adjustment screw to thereby change the quantity of reflector-side projection of the zero point adjustment screw.
