Claims

[Claims for Utility Model Registration] (1) An intermediate plate is provided between the flywheel and the pressure plate, and first and second clutch disks are provided on both sides of the intermediate plate, and these In a multi-plate clutch in which the torsional rigidity of the clutch discs changes in multiple stages and the hysteresis torque width of the first stage of these clutch discs is made small, the hysteresis torque width of the second stage of at least one clutch disc is set to be the same as that of the first stage. 1. A double disc clutch, characterized in that the hysteresis torque width is set to be larger than the hysteresis torque width, and the hysteresis torque width of the second stage of the one clutch disk is set to increase stepwise. (2) The clutch disks of the first and second clutch disks have each spline hub held between a clutch plate and a retaining plate,
A damper window is provided at the same position of the hub, the clutch plate, and the retaining plate;
A torsion spring consisting of a master spring and a slave spring provided inside the master spring is attached to the damper window, and one clutch disc is a disc disposed on the outside of the clutch plate and/or the retaining plate. A spring, two sub-plates that contact only the main spring and sandwich the disc spring, and a stud pin that passes through the clutch plate, the hub, and the retaining plate to connect these sub-plates to each other. , the diameter of the through hole of the hub through which the stud pin passes is set to be slightly larger than the amount of displacement of the damper window until it compresses the child spring and comes into contact with the master spring. The double plate clutch described in .
