ABSTRACT:
A drive apparatus for an opening and closing mechanism includes an electric motor, a clutch, a reduction gear unit and a timer mechanism. The clutch includes a coupling having first and second halves engageable with each other, and an actuator mechanism for connecting and disconnecting the first and second halves. The first half of the coupling is operatively connected to a rotor of the motor. The reduction gear unit is operatively connected to the second half of the clutch. The reduction gear unit has an output shaft for being operably connected to the opening and closing mechanism. The timer mechanism is provided for regulating the operating period of time of the motor in response to the operation of the reduction gear unit.
