Abstract

A clutch device includes a clutch spring to urge a pressure plate in a first direction, and a stopper plate secured to a clutch center. The pressure plate includes a spring housing located to a side of a pressure-side assist cam surface in a rotation direction of the pressure plate and housing the clutch spring. The clutch device includes a reducer to reduce a restoring force of the clutch spring in a direction from the clutch spring toward the pressure-side assist cam surface during a time period until a center-side assist cam surface and the pressure-side assist cam surface approach and contact each other from a state of being spaced apart from each other in the rotation direction.
