Abstract
A rectangular-type headlamp having improved air circulation in its interior to prevent fogging of the interior surface of the front lens by deposition of water vapor or an oily film. The front lens is provided with a stepped portion along an upper side edge portion projecting from the rear side thereof and lying in an inclined relation with respect to the upper edge. Thermal stress is relieved by forming the side edges of the front lens in a recessed shape in the region where the front lens is mechanically fastened to the lamp body.
