ABSTRACT:
A vehicle headlamp is provided with a leveling unit and a mechanical drive type beam switching device having one actuator mechanism. A low beam is switched to a high beam by driving the actuator of the leveling unit so as to tilt a reflector upward by an angle greater than a maximum upwardly-tilted angle at the time of leveling adjustment in order that the actuator may be set for common use. Moreover, a bulb holder is vertically tiltably supported by the reflector and tilted together with the reflector up to the aforementioned maximum upwardly-tilted angle on one hand, and the bulb holder is fixed to the maximum upwardly-tilted angle separately from the reflector by a stopper pin while the reflector may coincide with a high-beam upwardly tilting angle.
