Actuator device

1 . An actuator device comprising:

a case having a cover that covers a motor housing unit and a gear housing unit;

a motor housed in the motor housing unit of the case;

an output gear rotatably housed in the gear housing unit of the case, the output gear driven to rotate via a deceleration gear by the driving shaft of the motor;

an output shaft rotatably supported by the case and rotating together with the output gear; and

an output member mounted on the output shaft;

a stopper element rotatably mounted on the output shaft;

a stopper where the stopper element is locked to the inner surface of the cover to limit the rotation angle of the output gear;

a receiving recessed part for receiving the stopper element formed on the top surface of the output gear; and

a projection formed on the output shaft facing the inside of the receiving recessed part, wherein

the stopper element is respectively provided with a locking projection part that is locked to and separated from the projection of the output shaft and at least a pair of stoppers, and

at least a pair of stoppers are provided on the inner surface of the cover where each stopper of the stopper element is brought into contact with and locked to the output gear in order to limit the rotation angle of the output gear.

2 . The actuator device according to claim 1 , wherein

the stopper element is formed in the shape of an approximate disc having a cylindrical part in the center thereof,

the locking projection part is integrally protruded above the inner peripheral surface of the cylindrical part of the stopper, and

at least the pair of stoppers is integrally protruded above the top surface of the stopper element.
