Abstract
A multiplate clutch is provided with two types of frictionally engaging elements and a piston with plural pressing raised portions formed thereon. The frictionally engaging elements of at least one type are each provided with small waves. The two types of frictionally engaging elements are alternately arranged on two members such that in a state of relative rotation between the two members, rotation is transmitted via the frictionally engaging elements as needed. The waves on each of the frictionally engaging elements of the at least one type are arranged such that positions of swell portions or recess portions of the waves are shifted in phase from positions of the pressing raised portions of the piston.
