Abstract: A vehicle headlamp includes a moveable shade. The front end of the shade body of the movable shade is formed into a substantially semispherical shape. The maximum radius of the pivotal locus of the shade body is smaller than conventional shades that have a front end portion formed into a cylindrical shape. Further, a slot is found in the front end portion that extends along the pivotal face of the movable shade. Therefore, the shade body and the discharge bulb do not interfere with each other even when the movable shade is caused to pivot, and the maximum radius of the pivotal locus of the shade body is further reduced. Thus, the shade body of a fixed shade can be smaller in size so that a greater space can be secured for use in disposing the fixed shade within an allowable range that refrains from unnecessarily shading the light reflected from a reflector.
