Claims

[Scope of utility model registration request]

A cylindrical release bearing assembly extending approximately in the longitudinal direction of the clutch is disposed inside the clutch housing, and a release fork extending from the outside of the clutch housing to near the outer periphery of the release bearing assembly is rotatably supported by the clutch housing. providing the assembly with first and second sleeves that are slidably fitted to each other in the longitudinal direction of the clutch, with the front portion of the second sleeve being positioned radially outward of the rear portion of the first sleeve;
The front part of the first sleeve is connected to a diaphragm spring for biasing the pressure plate, and the rear part of the second sleeve is provided with a release bearing and an operated part operated in the longitudinal direction of the clutch by a release fork. An elastic ring is attached to the front inner periphery of the second sleeve so as to be immovable in the axial direction but expandable in the radial direction, and a groove in which the elastic ring in a contracted state can be fitted in an axially immovable manner is attached to the rear outer periphery of the first sleeve. At the rear of the groove, a guide surface extending to the rear end is formed on the outer periphery of the first sleeve by a tapered surface whose diameter decreases toward the rear, and an elastic ring is formed relative to the first sleeve from the rear. When the elastic ring moves forward, the elastic ring rides on the guide surface and expands, thereby allowing the elastic ring to move to the groove. The elastic ring is formed of an annular member having an extending notch and is interrupted at one point, and both ends of the elastic ring protrude outward in the radial direction of the second sleeve through the notch. A clutch release bearing mechanism characterized in that the elastic ring can be expanded and removed from the groove by moving the clutch.
