Dazzlement preventing reflection mirror driving unit for vehicle

Abstract

Abstract PURPOSE:To improve the cost efficiency and the space efficiency in a dazzlement preventing reflection mirror driving unit for vehicles, by providing a common rear detection unit for preventing dazzlement both of a room mirror and of side mirrors. CONSTITUTION:A rear detection unit 50 comprises two photodiodes 54 and 55 disposed in a housing 51 having two slits 52 and 53, and is arranged such that the side of the housing on which the slits are provided faces to the back of the vehicle. The slits 52 and 53 are positioned in such a relation with the photodiodes 54 and 55 that a light beam A exactly from the back of the vehicle is detected by both photodiodes 54 and 55; a light beam B from the left-hand back is detected only by the photodiode 54; and a light beam C from the right-hand back is detected only by the photodiode 55.
