Abstract
A reducing motor including a rotor with an armature shaft, a reducer housing (2) containing a gear wheel (3) engaging a worm on the shaft, and a shock absorber (5) housed in the gear wheel and rotationally integral therewith. The unitary shock absorber has circumferential notches (8) engageable both by radial flanges 87) on the gear wheel and by elements (10) for driving an output member (11), and chamfers (90) are provided on the edges of the notches to ensure gradual torque-dependent angular deflection of the shock absorber and make it easier to mount the same automatically on the hub of the gear wheel.
