ABSTRACT:
A vehicular headlamp in which the lamp body has a reduced susceptibility to deformation due to external forces and a high resistance to heat generated by a light projecting unit. The headlamp is a projection-type vehicular headlamp in which a light projecting unit including a light source, a substantially ellipsoidal reflector, and a projecting lens is mounted in a lamp chamber defined by a lamp body and a front lens. The lamp body has a light source attachment opening formed in a rear end wall thereof. In accordance with the invention, the rear end wall of the lamp body is partially expanded rearward to form expanded walls which protrude along the light source attachment opening.
