Claims

[Claims for Utility Model Registration] A disk plate and a sub-disc plate having facings that are selectively frictionally engaged with the drive shaft side and a flange of a clutch hub spline-fitted with the driven shaft side are assembled so as to be relatively rotatable,
A clutch disk having a torsion spring disposed between the two is characterized in that the torsion spring is set to a low spring constant and is provided with means for changing its pretorque in accordance with the rotational speed. Clutch disc.
