ロツクアツプ装置。 A lock-up piston is slidably fitted onto the outer peripheral surface of the hub portion of the turbine runner and connects or disconnects the turbine runner from the pump impeller, and a lock-up piston is fitted into an annular groove bored into the outer peripheral surface of the hub portion of the turbine runner. In the torque converter lock-up device, the torque converter lock-up device includes a seal ring that is supported by the lock-up piston and seals between a sliding surface between the inner circumferential surface of the lock-up piston and the outer circumferential surface of the hub portion of the turbine runner. A torque converter characterized in that an oil pressure receiving area of one side communicating with a release side hydraulic chamber for sending release hydraulic pressure is set larger than an oil pressure receiving area of the other side communicating with a connection side hydraulic chamber sending connection hydraulic pressure. Lockup device.
