Abstract
A device capable of tilting a reflector installed in a lamp body for adjusting the body's optical axis is provided. Workability of the process for securing the ball bearing to the reflector can be simplified and dislocation of the ball bearing can be prevented.
Claims2
A vehicle lamp having a lamp body comprising:
- a reflector disposed within the lamp body;
- a light source detachably installed to the reflector;
- an actuator for tiltably moving the reflector with respect to the lamp body, wherein the actuator is disposed on the lamp body and having an actuator rod which is actuated to move linearly along the optical axis of the reflective;
- and
- a ball bearing secured to the reflector to support pivotally a distal spherical end of the actuator rod so as to convert the linear movement thereof into the tilting movement of the reflector, the ball bearing having first and second anchor parts to be secured to the reflector, the first anchor part being constructed to be secured to the reflector by a fastener means, and the second anchor part being constructed to be fitted with the reflector,
- wherein the second anchor part has a pin hole at the crossing center of the cross-shaped gap, and the reflector is provided with a pin projecting from the top end of the cross-shaped boss so as to be fitted into the pin hole, the second anchor part has a plurality of fitting walls disposed to define a cross-shaped gap therebetween, and the reflector is integrally provided with a cross-shaped boss having cross-shaped cross section, which can be fitted into the cross-shaped gap.
