Claims (1)

[Scope of utility model registration request] A clutch in which a disk plate that receives torsional torque from the drive side and a hub that transmits torsional torque to the driven shaft are arranged on the same rotation center line and are connected in such a way that the relative torsional angle can be increased or decreased. In the disk, the disk plate and the hub each form a friction surface that faces each other in a direction parallel to the rotation center line and receives a pressing force in the direction of the rotation center line, and these friction surfaces have a torsion angle. A clutch disc characterized in that convex portions are formed along the displacement direction.
