Claims

[Scope of utility model registration request]

A frame for supporting a mirror on a base fixed to a door of a vehicle is rotatably supported in the front and rear directions at its base end on the door side, and is driven by an electric motor built into the frame and the electric motor. In the electric door mirror device for a vehicle in which the frame is rotated by a speed reduction mechanism that reduces the resulting rotation, the speed reduction mechanism includes a ring gear having internal teeth, an internal gear having external teeth, and the frame. A rotor is provided that sequentially eccentrically moves one gear toward the other gear in order to sequentially shift the meshing position of the external teeth and the internal teeth in the circumferential direction, and is coaxially assembled on the shaft support of the base and the frame. one of the two gears rotatably engages with the base or frame via a frictional engagement means;
The other gear engages with the frame or base so as to be integrally rotatable in the circumferential direction, so that rotation of the rotor causes both gears to rotate relative to each other in the circumferential direction by a difference in the number of teeth between the external teeth and the internal teeth. a planetary gear mechanism consisting of a planetary gear mechanism, and a large-diameter gear disposed on the distal end side of the rotor in the longitudinal direction of the frame, rotatably supported by the frame, and meshed with a large-diameter gear integrally provided with the rotor, so that the worm is driven by the electric motor. An electric door mirror device for a vehicle, comprising: a small-diameter gear rotated through a small-diameter gear;
