Claims

[Scope of utility model registration request]

A spline hub having an annular flange on the outer periphery, a pair of annular side plates connected to each other by stop pins and located on both sides of the annular flange, and a window hole formed in the side plates and the annular flange. A clutch disk assembly including a torsion spring inserted to connect the side plate and the spline hub so as to be relatively rotatable at a predetermined angle, wherein one side plate of the pair of side plates and an annular flange portion; An annular friction plate is provided between the other side plate and the annular flange portion, and an annular plate that engages with the annular flange in a relatively rotatable manner;
a diaphragm spring that engages with the other side plate in a relatively non-rotatable manner and biases the annular plate toward the annular flange portion; the diaphragm spring includes an annular portion that engages with the other side plate; , and a plurality of tongue portions projecting radially outward from the annular portion,
The annular plate has a protrusion that comes into contact with the diaphragm spring or the continuous tongue, and the protrusion has a radial position that is displaced stepwise or continuously depending on the circumferential position. A clutch disk assembly characterized in that the contact position between the protruding portion and the tongue portion moves radially inward as the torsion angle increases.
