| 1. A vehicle headlamp comprising:
a light source bulb for emitting light;
a base member to which the light source bulb is fixed;
a reflector with an optical axis for reflecting the light emitted from the light source bulb;
a projecting lens for projecting light reflected by the reflector to a front side along an optical axis; and
a shade for blocking a portion of light directed from the reflector toward the projecting lens;
wherein the vehicle headlamp includes a reflector displacing mechanism to move the reflector linearly from a first position
to a second position which is upward and toward the base member, wherein the optical axis at the first position is parallel
to the optical axis at the second position, and wherein the reflector displacing mechanism includes:
a pivoting arm attached pivotably to the base member and operable to urge the reflector,
an actuator for pivoting the pivoting arm, and
a link mechanism connecting the pivoting arm and the reflector and operable to convert a pivoting displacement of the pivoting
arm into a straight moving displacement of the reflector.
