ルスモータの回転力伝達装置。[Claims for Utility Model Registration] 1. A drive gear driven by the output shaft of a step motor, a driven gear attached to the shaft of a control valve and meshing with the drive gear, and a drive gear that biases the control valve in the direction of opening it. In a control valve drive device for a traction control system that has a return spring that biases the shaft of the control valve and a driven gear to rotate in one direction, what is the torque that the drive gear 23 receives from the return spring 16? Second springs 34 and 35 are provided to rotate in opposite directions, and the torque of the second springs 34 and 35 in the drive gear 23 is transferred to the return spring 1.
6. A rotational force transmission device for a pulse motor, characterized in that the torque is set to be relatively smaller than the torque received by the drive gear 23. 2. The step motor rotational force transmission device according to claim 1, wherein the second spring 34 is attached to the shaft 32 of the drive gear 23. 3 A crash prevention gear 36 provided so that the second spring 35 meshes with the drive gear 23
2. The rotational force transmission device for a pulse motor according to claim 1, wherein the rotational force transmission device is mounted on a rotating shaft 37 of a pulse motor.
