Claims

[Scope of utility model registration request]

A gear type reduction motor with at least a medium reduction ratio, a cylindrical bearing that rotatably supports the anti-load side of the output shaft of this reduction motor and has a large radial clearance with the anti-load side, and a bearing on the load side of the output shaft. a load-side bracket of the reduction motor which is rotatable through the reduction motor; an intermediate shaft having one end fitted and connected to a protruding portion of the output shaft from the outer end surface of the load-side bracket and a small gear formed on the other end; A gear reduction mechanism with at least a medium reduction ratio connected to a small gear, a housing housing the reduction mechanism, and a housing detachably connected to one end of the housing and rotatable on the load side of the intermediate shaft via a bearing. A gear-type high-reduction electric motor comprising: a bracket supported on the load-side bracket; and a cover body that connects the bracket to the load-side bracket and surrounds the intermediate shaft portion.
