Remote operating device of back mirror

Abstract

Abstract PURPOSE: To make constitution simple connecting the crank mechanism for tilting a back mirror around the symmetrical axis in its horizontal and vertical directions by the slipping which is provided to the 1st and 2nd planetary gears of the planetary reduction gear mechanism of a drive motor and which slips at more than predetermined torque. CONSTITUTION: In the case of tilting a mirror 4 around its horizontal axis, a motor 15 is driven in a desired forward or backward direction by holding the 1st planetary gear 19 detained by a detaining piece 24 so as not to revolve. The revolutions of the motor 15 are reduced and transmitted in order of a sun gear 16, the 1st and 2nd sattelite gears 17, 18, and the 2nd planetary gear, then a crank 27-2 is rotated together with the boss 20c of the 2nd planetary gear by the friction force of a splipping 25-2 and this causes a crank pin 26-2 to revolve as well. The crank rod 14-2 connecting to the pin 13 of a back mirror holder 5 tilts the mirror along with rotating of the crank pin 26-2. The tilting around the vertical axis is also accomplished in the same manner. Thereby, the mechanism can be made simple. COPYRIGHT: (C)1981,JPO&Japio
