Claims

[Scope of utility model registration request]

A motor, a reduction gear mechanism connected to the output shaft of the motor to reduce rotation, and a reduction gear mechanism interposed between two coaxial gears of the reduction gear mechanism, with an angle of play in the rotational direction between the two gears. In an actuator that includes a buffer mechanism and an output take-out member using a rod or lever that converts the final rotation of a reduction gear mechanism into a required motion and transmits it to a driven body, the buffer mechanism is a An actuator consisting of a spring whose ends engage and disengage from stop projections, and a damper located inside surrounded by both ends of the spring.
