ABSTRACT:
This clutch device has a first cam mechanism and a second cam mechanism disposed on a relatively rotatable a pair of members. When the first cam mechanism is pushed by a piston to one of the pair of members rotating in a direction, the first cam mechanism generates a thrust force corresponding to an input torque and thereby the relatively rotating members are engaged. When the second cam mechanism is pushed by a piston to one of the pair of members rotating in a reverse direction, the second cam mechanism generates a thrust force corresponding to the pushing force of the piston, and thereby the relatively rotating members are engaged. A return spring giving a biasing force to separate the second cam member from the one of relatively rotating member is designed not to reduce the thrust force generated by the first cam member during the action of the first cam mechanism.
