PURPOSE:To generate the main beam with excellent visibility. CONSTITUTION:A first heal lamp main body 20 and a second head lamp main body 30 each having a light source and a reflector for reflecting the light from the light source forward are provided. The second head lamp main body is constituted of a light projecting unit 31 made by integration of a reflector 32 formed into the nearly elliptical shape, a light source 34 located at a first focus of the reflector, a projecting lens 36 for projecting and distributing the light led from the reflector forward, and a low beam forming shade 37 provided in the focus of the projecting lens, and the second head lamp main body forms the low beam. In a head lamp for forming the main beam in cooperation with the first heat lamp main body, a light quantity reducing shade 38 is stood at a position offset from the focus position of the projecting lens forward and backward in the optical axis L direction and the opposite side of the optical axis L against the main beam forming shade standing side to relax a difference of the light quantity between this side and far away of the main beam projecting area and improve the visibility far away. |
