Claims

[Claims for Utility Model Registration] (1) A piston body that is attached to a member on either one of the input and output sides so as to be able to press against and separate from the member, and that is rotatable integrally with the member on one side; A lock-up clutch for a fluid coupling, comprising: a disk body fixed to the other side member of the output and rotatable together with the piston body via a damper spring mechanism; a hydraulic chamber provided with at least one partition plate between the piston body and the disk body to allow a slight relative rotation of the piston body and the disk body, and to damp the relative rotation in a direction intersecting the circumferential direction. A lock-up clutch for a fluid coupling, characterized in that: (2) The scope of the utility model registration claim is that the hydraulic chamber is formed in a donut shape by projecting cylindrical portions with different radii from both the piston body and the disk body toward the other side. No.
A lock-up clutch for a fluid coupling described in (1). (3) The partition plate is installed in a cantilevered state in the hydraulic chamber, and the free end side thereof can be bent in the circumferential direction. Lock-up clutch for the fluid coupling described.
