Abstract The purpose of the present invention is to provide a motor for action auxiliary device. A push-out member assists the action of opening-closing member to protrude forward by following the driving force of motor, and its connecting relationship with the gear train can be blocked by releasing from engaging with the switching gear. The push-out member can be easily pushed back inside (toward the direction of origin) manually by users. The solution is to comprise: a gear train 3 to transmit the driving force of motor 2; a push-out member 5 to be brought into contact with an opening/closing member 4 for being slid through the driving force inputted by the gear train 3, and assisting the action of the opening/closing member 4 by the sliding operations of the push-out member 5. A contact gear 36 is installed on the gear train 3, and the contact gear 36 has a tooth part 36a engaged with the push-out member 5, and a defect part 36b to disengage from the push-out member 5, so that the push-out member can slide and move to assist the action of opening-closing member 4 by engaging with the tooth part 36a of the contact gear 36, and make the defect part 36b disengage from the push-out member 5, whereby the driving force of the motor 2 won't be transmitted to the push-out member 5, and at the same time, the force of the push-out member 5 will not be transmitted from the contact gear 36 to both sides of the motor.
