ABSTRACT:
A centrifugal hydraulic pressure cancel chamber is arranged at the back of a second piston member of a second hydraulic actuator for the second clutch. A first piston member of a first hydraulic actuator for a first clutch is situated behind the second piston. A centrifugal hydraulic pressure cancel plate is set at an inner periphery on a rotating member to prohibit axial movement and set at an outside periphery in a inside of the piston member oil-tightly. The inside surface of the second piston member and the cancel plate compose the centrifugal hydraulic pressure cancel chamber. A spring is placed between the second piston member and the cancel plate, and the centrifugal hydraulic cancel chamber and the spring work correspondingly to the first and the second piston members.
