Abstract
A multiplate clutch has an assistive cam mechanism comprising a first cam member having a first recess and a second cam member having a first tooth inserted in the first recess, wherein at least one of abutment surfaces of the first recess and the first tooth in a power transmitting state for transmitting power from an input member to an output member comprises a slanted surface for increasing an urging force of a clutch spring upon acceleration in the power transmitting state. The multiplate clutch is prevented from being connected abruptly while sufficiently reducing a load with which to operate the clutch. The angle of intersection between the slanted surfaces and a plane perpendicular to a clutch central axis is set to a range from 80 degrees to 85 degrees.
