Abstract
A pressure plate is movable in an axial direction to cause multiple driving friction plates and driven friction plates to come in pressure contact with each other. The pressure plate is biased by a clutch spring in a direction to bring the driving friction plates and the driven friction plates in pressure contact with each other. When acceleration torque is changed, an assist mechanism increases the pressure-contact force of the pressure plate. A pressure plate and a clutch inner are connected together and are capable of being separated from each other in an axial direction. When an assist mechanism increases a pressure-contact force of the pressure plate, the pressure plate is moved in a direction to bring driving and driven friction plates into pressure contact with each other, while the clutch inner is moved relative to the pressure plate in the same direction so as to be detached from the pressure plate.
