Claims

[Scope of utility model registration request]

(1) An electric motor and a gear type reduction part are integrally coupled, and the rotating shaft of the electric motor and the first gear shaft of the reduction part are connected through a buffer member so that they cannot rotate relative to each other, The rotating shaft is supported by a counter-load side bracket and an intermediate bracket of the electric motor through a pair of rolling bearings, and the first gear shaft is supported by a load-side bracket and an output shaft of the electric motor through a rolling bearing and both bearings. A reduction motor characterized by being supported by.

(2) The buffer member is unrotatably fitted into the slot provided at one end of the rotating shaft, and the rectangular protrusion provided at one end of the first gear shaft is unrotatably fitted. The reduction motor according to claim 1, characterized in that the motor is provided with a through hole that is fitted together.
