Claims

[Claims for Utility Model Registration] The output shaft of a rotary displacement output type motor having a predetermined maximum working angle range is set to a predetermined position within the maximum working angle range when the motor is not energized. The origin return mechanism mechanically returns to the original angular position, which includes: a driven shaft for transmitting the rotational displacement output of the output shaft to a load; a bearing that rotatably supports the driven shaft; and a bearing attached to the housing of the motor. a fixing plate supported in fixed relation to the output shaft; a coupling coupling the output shaft to the driven shaft; a movable side pin member, which is assembled around the driven shaft in a state where a bending torque is applied in advance, and both ends abut against both the movable side pin member and the fixed side pin member at each of both ends of the required operating angle range; A home return mechanism for a rotational displacement output type motor, comprising: a torsion coil spring having a torsion coil spring;
