A wet type multiple disc clutch transmits torque from an engine a transmission and a clutch engaging portion, a piston, a first oil passage, a second oil passage, and an operating oil supply unit. The clutch engaging portion includes a plurality of plate members. The first oil passage has one end on the piston side. The second oil passage has one end on the clutch engaging portion side. The operating oil supply unit switches a clutch engaged state, in which operating oil is supplied to the first oil passage from the outside and the operating oil in the second oil passage is drained to the outside, to a clutch disengaged state.
