Abstract
A window lifting and lowering apparatus that includes an arm pivotally moved to lift and lower a window of a vehicle. A cycloidal speed reducing mechanism is used for transmitting a rotational force of a drive shaft to the arm at a reduced speed. The cycloidal speed reducing mechanism includes a ring gear disposed in a fixed state, a planetary gear eccentrically rotated in a state of being brought into mesh with the ring gear by the rotational force of the drive shaft, a rotating disk for transmitting rotation of the planetary gear to the arm, and a stopper gear fixed to the ring gear for restricting a pivotal movement position of the planetary gear. In accordance with the eccentric pivotal movement of the planetary gear, a stopper pin provided on the planetary gear is made to impinge with a stopper projection provided on the stopper gear.
