するアクチユエータ。 An actuator comprising a deceleration mechanism that decelerates the rotation of a motor, an output mechanism that rotates a throttle valve in a valve opening direction and a valve closing direction, and an electromagnetic clutch that transmits and cuts off the rotation of the deceleration mechanism to the output mechanism. In the output mechanism, the first drive member is provided coaxially with the output shaft of the deceleration mechanism and interlocks with the throttle valve;
A clutch spring is provided astride the drive member and the output shaft, and transmits the rotation of the output shaft to the first drive member by rotation in the tightening direction via the electromagnetic clutch, thereby opening and closing the throttle valve. At the same time, the first driving member and the second driving member interlocked by the accelerator are engaged with each other with a gap formed by a spring, and the returning operation of the accelerator against the biasing force of the spring is detected in the gap. An actuator characterized by being provided with return operation detection means.
