Claims (1)

[Scope of Claim for Utility Model Registration] (1) Axial protrusions formed by bending the clutch cover toward the flywheel, or A stud pin protruding from the wheel side is provided, and a pair of wire rings extending in the circumferential direction is supported by the axial protrusion or the stud pin,
The diaphragm spring is supported by a fulcrum mechanism by sandwiching the radially intermediate portion of the diaphragm spring with a wiring, and the inner peripheral portion of the diaphragm spring is attached to the flywheel side when the clutch is connected between the diaphragm spring and the clutch cover. In a clutch cover assembly including a cone spring in the form of an annular disc, a clip made of a substantially rectangular flat plate is bent between the protrusions in the axial direction on the inner periphery of the clutch cover. A bent protrusion piece that is fixed to the flywheel side surface of the inward protrusion by contacting the side edge of the radially inward protrusion or the inner periphery of the wiring, or provided on one side of the clip. was in contact with the inner periphery of the wiring and fixed to the flywheel side surface of the inner periphery of the clutch cover, and the outer periphery of the cone spring was pressed against the clutch cover by the inner periphery of the clip to support the cone spring. A clutch cover assembly characterized by: (2) Provide protrusions toward the clutch cover in the axial direction at multiple locations on the outer periphery of the cone spring, and place the protrusions on the side edge of the inwardly protruding portion of the clutch cover or on the side edge of the window hole provided in the clutch cover. The clutch cover assembly according to claim 1, wherein some of the parts are brought into contact with each other from one side in the circumferential direction and others from the opposite side. (3) The diaphragm spring is supported by a fulcrum mechanism by the clutch cover at its radially intermediate portion, and there is a circle between the diaphragm spring and the clutch cover that urges the inner circumference of the diaphragm spring toward the flywheel when the clutch is connected. In a clutch cover assembly equipped with an annular plate-shaped cone spring, a clip made of a substantially rectangular flat plate is used, and a bent protrusion piece provided on one side of the clip is applied to the side edge of a tongue piece divided by a radial slit of a diaphragm spring. Touch it and stick it to the tongue piece,
A clutch cover assembly characterized in that the cone spring is supported by pressing the inner circumferential edge of the cone spring against a diaphragm spring by the outer circumferential edge of the clip.
