Abstract
Provided is a drive control mechanism of a geared motor capable of executing a stopping operation between a start point and an end point in a drive range, maintaining this stopping operation, and smoothly and reliably executing respective operations that start from this stopped state without applying any external force other than a drive input of the electric motor. The drive control mechanism of a geared motoraccording to the present invention includes the geared motorformed by integrating an electric motorwith a speed change unitincluding an input shaft that is a drive shaftof the electric motor, and braking meansfor controlling braking in each of driven and stopped states in an output shaftof the speed change unit, and the braking meansincludes a rotating partrotatably and pivotally supported by the drive shaftof the electric motor, and including a permanent magnetdisposed in an annular shape, and a fixing partfixed to a caseof the electric motor, and including a permanent magnetdisposed facing the permanent magnetof the rotating partwith a different polarity in the stopped state, and disposed in an annular shape.
