摘要： A clutch portion is disposed between a front cover and a turbine. A piston is movable in an axial direction and turns the clutch portion into a torque transmission state. A sleeve supports an inner peripheral surface of the piston such that the piston is movable in the axial direction. An oil chamber is supplied a hydraulic oil for activating the piston to turn the clutch portion into the torque transmission state. The sleeve includes an inner peripheral side oil channel and an outer peripheral side oil channel. The inner peripheral side oil channel leads the hydraulic oil residing on an inner peripheral side of the sleeve to an outer peripheral side. The outer peripheral side oil channel leads the hydraulic oil led thereto through the inner peripheral side oil channel to the oil chamber.
