Claims

[Scope of utility model registration request]

The release bearing is fitted onto the outer periphery of the clutch output shaft via a sleeve, and the inner periphery of the diaphragm spring is engaged with the radially outward flange of the release plate provided on the outer periphery of the release bearing. This is a pull type in which the clutch is sandwiched between the radially inward support plate and the plate body, and by moving the release bearing axially rearward, the inner circumference of the diaphragm spring is moved in the same direction to disconnect the clutch. In the clutch, the flange has an overhanging portion that has an arcuate cross section toward the plate main body, and the release plate has a structure in which it is divided into two parts: a radially outer body having the overhanging portion and a radially inner body; A support plate is engaged with the inner body, each contact surface of the inner body with the outer body is made into a slidable concave and convex spherical shape, and the outer body is brought into contact with the inner peripheral portion of the diaphragm spring. A pull-type clutch, characterized in that the clutch is adapted to slide against the inner body when the clutch is in the state of the clutch.
