PROBLEM TO BE SOLVED: To accomplish reduction of a chattering sound which may be generated from a periphery of a connection part with a worm shaft in operation of an electric motor. SOLUTION: The electric mirror device 1 is formed based on an actuator 5 comprising the worm shaft 31 connected to a rotation shaft 11 of the electric motor 1 and rotated/driven by the electric motor 1; a ring gear 32 engaged with the worm shaft 31; and a bolt-like adjuster 4 having a male screw part 44 engaged with a female screw part 321 formed inside of the ring gear 32, reciprocated accompanying with rotation motion of the ring gear 32 and bearing inclination motion of a mirror plate 7 with a mirror 9. A spring 2 operated so as to absorb relative thrust force is provided on a connection part of the rotation shaft 11 and the worm shaft 31. COPYRIGHT: (C)2007,JPO&INPIT
