Abstract
Clutch-release device comprising a centrally holed diaphragm 1 which has a central part cut, by means of slits 5 into fingers 4 that point radially inwards, a thrust rolling bearing 13 and an operating element 14 mounted on a part which is distinct from the one supporting the diaphragm and in at least axial contact with the rolling bearing 13. The latter comprises a rotating race 16, a radial portion 25 of which bears against the internal end of the fingers 4 of the diaphragm 1, a non-rotating race 17, a radial portion 21 of which is in contact with the operating element, and a row of rolling bodies 18. The rotating race 16, made of pressed sheet metal, on its radial portion 25 in contact with the diaphragm 1 comprises at least one axial deformation 26 which is obtained without removing material, and the edges of which are capable of interacting with the flanks of one finger 4 of the diaphragm 1, the deformation 26 being smaller in size than the thickness of a finger 4 of the diaphragm 1.
