Claims

[Scope of utility model registration request]

It includes a torque converter input/output element, and a lock-up clutch that directly transmits the rotation of the torque converter input element to the torque converter output shaft in response to the pressure difference between the converter chamber and the lock-up control chamber, and connects the torque converter output element to the torque converter output shaft. The torque converter output element can be moved in the axial direction according to the pressure difference by being slidably fitted into the lock-up control chamber to define a pressure chamber between the two and guiding the pressure of the lock-up control chamber. The element is drive-coupled to the torque converter output shaft via a cam mechanism so as to rotate relative to it and move in the axial direction according to the difference between the generated torque and the transmission torque of the lock-up clutch, and the opening degree is changed by the axial movement of the torque converter output element. In the lock-up torque converter, the lock-up torque converter is provided with a variable orifice that changes to adjust the degree of communication between the converter chamber and the torque converter output shaft. A slip control device for a lock-up torque converter provided with a sealing means.
