A clutch disengage/engage control mechanism for switching disengagement/engagement of the clutch actuation mechanism. A clutch piston having opposite sides facing toward a control hydraulic chamber and a hydraulic canceler chamber. A division wall member forming the hydraulic canceler chamber between the division wall member and the clutch piston for forming an oil passage, which introduces lubricating oil toward the friction plates, in cooperation with the clutch inner.
