Abstract
A mirror unit of the present invention includes a base member constituted of an upper plate portion, a lower plate portion, a connecting portion connecting the upper plate portion and the lower plate portion, and wall portions. A mirror holder for holding a mirror is pivotally supported between the upper plate portion and the lower plate portion. A recess is formed in the wall portions. An adjuster is mounted in the recess. Screw holes extend through the recess, and adjusting screws are engaged in the screw holes. Lifting amounts of plate portions of the adjuster can be adjusted by the adjusting screws. The tilt angle of the mirror is adjusted so that the mirror is properly tilted with respect to a light flux from either one of two lamps.
