MIRROR DEVICE FOR CAR
Document Type and Number:
Japanese Patent JPS6277257
Kind Code:
A
Abstract:
PURPOSE:To make a device compact by coaxially assembling a planetary gear mechanism constituted of a ring gear, an inscribed gear, a rotor, etc. to the pivotal section of a base and a frame in a mirror device. CONSTITUTION:A plate 21 is fixed to a base 20, and a cylindrical support shaft 22 is erected at the lower end of the plate 21. A ring gear 23, an inscribed gear 24, and a rotor 25 constituting a planetary gear mechanism are assembled on the support shaft 22, and a frame 27 supporting a mirror 26 is also assembled. When a motor 40 is driven and a rotary shaft 40a is rotated, a rotor 25 is rotated via a worm 39, a worm wheel 38, and flat gears 25b, 37, the inscribed gear 24 is eccentrically shifted by the eccentric shaft section 25a of the rotor 25, then the engagement position between the outer teeth 24a of the inscribed gear 24 and the inner teeth 23a of the ring gear is shifted in sequence. Thereby, when the rotor 25 is rotated 360 deg., the inscribed gear 24 is rotated in the direction opposite to the rotational direction of the rotor 25 with respect to the ring gear 23 by the difference of teeth of the outer teeth 24a and inner teeth 23a.
