Abstract

In a push-type clutch, a facing wear adjustment nearly annular adjust ring with which an outer peripheral part of a diaphragm spring contacts from a side opposite to a flywheel is screwed into an inside face of a pressure plate so as to be movable in a clutch axial direction, so that a worm wheel is rotated by a bracket moving in a clutch axial direction to rotate the adjust ring when a facing is worn out. The adjust ring position can thus be adjusted automatically to a diaphragm spring side by a wear amount of the facing.
