PROBLEM TO BE SOLVED: To suppress the deterioration of optical performance. SOLUTION: An aperture member 35 is formed integrally at the position opposed to a positioning hole 27 in a housing 21 on which the positioning hole 27 is formed for positioning a light source unit on a wall face. Thus, the relative positions of the positioning hole 27 and the aperture member 35 are decided when the housing 21 is formed, and the housing 21 in which the relative positions of the positioning hole 27 and the aperture member 35 are excellently secured is available when the housing 21 is formed by a projection molding of a molten resin, for example.
