タ。 A deceleration mechanism that decelerates the rotation of the motor, a first drive member driven by the deceleration mechanism, and a second drive member that drives the throttle valve are provided at coaxial positions, and the first and second drive members are connected to each other. The actuator includes a clutch spring that is wound around the clutch spring and transmits the rotation of the first driving member to a second driving member when the motor rotates in the winding direction, and the throttle valve is driven by the rotation of the motor in the winding direction. An actuator characterized in that the clearance between the and the second driving member is slightly smaller than the clearance with the first driving member or zero.
