PURPOSE:To prevent a reflector from interfering with a lamp and make effective use of the area of the reflector so as to miniaturize the reflector and the lamp and also improve the illumination characteristic of the lamp by disposing the lamp from the direction diagonal to the optical axis of a lens, and also disposing the reflector opposite to the lamp. CONSTITUTION:A lamp 8 to be disposed through an opening which is tilted with respect to the optical axis of a lens 17 is disposed from the direction diagonal to the optical axis and also a reflector 23 for reflecting light from the lamp 8 in the direction of the optical axis is disposed below the lamp 8 in a lamp room. The effective use of the area of the reflector 23 is thereby possible and the reflector 23 can be formed by a single reflector and also the reflector 23 and the lamp 8 are both miniaturized and at the same time the illumination characteristic of the lamp 8 is improved. |
