Claims

[Scope of utility model registration request]

The pump housing is provided with a control chamber that supports an annular piston with an orifice hole and is separated from a fluid circulation chamber, and a clutch plate is provided on the turbine, and the movement of the piston presses down the clutch plate, thereby connecting the pump and the turbine. The lock-up clutch mechanism for a torque converter is such that the pump housing is provided with a support cylinder for the piston, and the piston is supported in the support cylinder so as to be able to reciprocate, while the support cylinder has free play. A first sealing material is provided on the end side for sealing the center of the piston and regulating the backward movement position of the piston, and a first sealing material is provided near the outer periphery of the piston to contact the side wall of the pump housing to prevent the piston from moving. a second sealing member that seals the external part of the piston and is elastically deformed by forward movement of the piston;
A lock-up clutch mechanism for a torque converter, characterized in that the piston is returned to the return position by the restoring force of the second seal member.
