Abstract
A pressure plate of a clutch device includes a clutch outer member for supporting friction discs, and a clutch center member for supporting clutch discs. The pressure plate has a deep hole portion for accommodating a clutch spring acting between the pressure plate and the clutch center member; and a through hole at a center thereof extending between an inside and an outside of the clutch device in a clutch axis direction. Oil is supplied from the outside into the through hole. The pressure plate has a radial passage extending in a radially outward direction from the through hole at an axially inner end portion of the through hole to make the inside and outside of the through hole communicate with each other. An annular rib is formed on a peripheral surface of an outer end portion of the through hole extending toward the center of the through hole.
