Claims

[Scope of utility model registration request]

In a diaphragm clutch release mechanism in which the radially intermediate portion of the diaphragm spring is supported by an annular fulcrum and the tip of the release bearing is brought into contact with the inner peripheral end of the diaphragm spring, the tip of the release bearing is rounded, Of the roundness, the radius of the part on the fulcrum side is formed to be larger than the radius of the part on the opposite side, and the degree of roundness of the part on the fulcrum side is adjusted to such an extent that the release load does not decrease during the release operation. A release mechanism of a diaphragm type clutch, characterized in that a portion of the clutch is formed so as to move toward a fulcrum.
