PROBLEM TO BE SOLVED: To give uniformly clear surface at a non-lighting time, and reduce the loss of lighting. SOLUTION: The reflection face 34 of the reflector 12 of a rear combination lamp is provided with the main reflection portion 34A of a U-shaped cross section located in the vicinity of a bulb 16, a dummy face 34B which hardly has any effect on irradiation and is located close to the lens 30, and a curved face 34C. Recessed portions 36 and protrusion portions 38 are formed on the dummy face 34B and the curved face 34C of the reflection face 34. The vertical cross section shapes of the respective protrusion portions 38 are sawtoothed, and the tilt anglesθof the tilt faces 38A of sides opposite to a lens 30 to a perpendicular line are unified so as to make a predetermined angle. The protrusion portions 38 are formed along a horizontal direction in parallel with a predetermined pitch so that the incident light from aslant above is reflected to aslant below. |
