ABSTRACT:
A clutch actuator is provided to stabilize a state of clutch engagement. A rotating member is rotationally driven on a rotating shaft by a motor. A clutch operating member includes two ends. One end of the clutch operating member is pushed by a push force of a clutch spring and the other end is pivotally supported on the rotating member by a shaft. The clutch operating member disengages the clutch when moved in a direction against the force of the clutch spring. An auxiliary biasing mechanism also acts on the rotating member. One end of the auxiliary biasing member is supported on a vehicle side and the other end is pivotally supported on the rotating member by a shaft. The auxiliary biasing member can include a compressible coil spring. The rotating member rotates in a first direction to move the clutch operating member in a direction of clutch engagement. When the clutch is engaged, the combined torque on the rotating member, which is produced by forces asserted by the auxiliary biasing mechanism and the clutch operating member, bias the rotating member in the first direction.
