Claims

[Claims for Utility Model Registration] (1) A diaphragm spring having an enlarged opening at the outer end of a radial slit extending from the inside in the radial direction to the middle part, the outer fulcrum of the diaphragm spring being supported by a clutch cover,
The intermediate fulcrum part on the outside of the enlarged opening contacts the fulcrum land of the pressure plate, the inner fulcrum part is supported by a release bearing, and the release bearing is placed axially rearward on the opposite side from the pressure plate. In a pull type clutch that shuts off the clutch by moving the clutch, each of the plurality of pins is fixed to the pressure plate while passing through the enlarged opening, and protrudes from the diaphragm spring on the opposite side of the pressure plate. A disc-shaped cone spring is placed between the outward flange of the pin head and the diaphragm spring, with the inner periphery touching the corner formed by the outward flange and the outer periphery touching the intermediate fulcrum of the diaphragm spring. A pull type clutch cover assembly characterized by being arranged in contact with each other. (2) A diaphragm spring having an enlarged opening at the outer end of a radial slit extending from the inside in the radial direction to the middle portion, the outer fulcrum of the diaphragm spring being supported by a clutch cover,
The intermediate fulcrum part on the outside of the enlarged opening contacts the fulcrum land of the pressure plate, the inner fulcrum part is supported by a release bearing, and the release bearing is placed axially rearward on the opposite side from the pressure plate. In a pull-type clutch that disconnects the clutch by moving the clutch, protrusions that protrude through the enlarged opening are formed integrally with the pressure plate at multiple locations in the circumferential direction of the pressure plate, and the protrusions A pull-type clutch cover assembly characterized in that a clip is fixed to the tip of the diaphragm spring for contacting an intermediate fulcrum of a diaphragm spring.
