Abstract
A vehicle headlamp including a reflector and a light-source bulb installed in the reflector so that the bulb supporting portion of the light-source bulb is slid and fitted on the inner peripheral surface of an annular wall formed in the rear end of the reflector in a cylindrical shape. A plurality of notches are formed through the annular cylindrical wall so as to be positioned in front of the bulb supporting portion of the light-source bulb, thus allowing the heat inside the reflector to escape to the outside through the notches and avoiding the reflector from being heated to a high temperature.
