Abstract
A reflector made of a synthetic resin material is positioned and fixed in a heat sink member. At a position spaced from the positioned and fixed portion, a deformation prevention portion for preventing a warping deformation of the reflector is provided for a respective one of the reflector and the heat sink member, thus preventing a warping deformation of the reflector due to a heat generated from a semiconductor-type light source. As a result, the impairment of light distribution performance, caused by a slight warping deformation of the reflector, is avoided. In this manner, a thermal deformation of the reflector due to the heat generated from the semiconductor-type light source is prevented.
