囲第1項記載のトルク伝達装置。[Claims for Utility Model Registration] 1. A clutch drum, a piston that is slidably housed in the clutch drum and defines a fluid chamber between the clutch drum and the clutch drum, and a plurality of pistons that are spline-coupled to the clutch drum. and a second friction member that is spline-coupled to a rotating member disposed coaxially within the clutch drum and arranged alternately with the first friction member, and supplies pressurized fluid to the liquid chamber. In the torque transmission device for transmitting torque between the clutch drum and the rotating member, the piston is provided with a valve that can open or shut off the pressure in the liquid chamber, and the clutch is operated within a predetermined range when the pressure in the liquid chamber is near zero. During rotation, the valve is closed, and as the rotation decreases or the pressure in the liquid chamber increases, the valve is temporarily opened, and as the pressure increases further or the rotation decreases, the valve opens again. A torque transmission device characterized by closing a valve. 2. A valve body movable in the radial direction of the piston or clutch drum and having a through hole in the axial direction of the piston or clutch drum, communicating with the liquid chamber and moving the valve body in the radial inward direction by the pressure in the liquid chamber. 2. The torque transmission device according to claim 1, wherein the valve is constituted by a communication path for moving the valve and a communication path for releasing the pressure inside the liquid chamber through a through hole of the valve body.
