    • PURPOSE: To simplify the structure of a clutch apparatus and reduce its size by placing within a hydraulically or pneumatically driven cylinder chamber the resilient means required for control of tension means. CONSTITUTION: A coned disc spring 10 is enclosed in a cylinder chamber 9 and a portion between the ring flange 2a of an end face flange 2 and an outer cylinder 6 is axially energized via a retaining ring. Thereby the outer cylinder 6 is moved leftward relative to the end face flange 2 to compress a conical tension plate 4 as the bore of the tension plate 4 is reduced and a bush 3 that has become easier to deflect diametrically is pressed against a shaft. This pressure is calculated so that a predetermined torque is safely transmitted from the end face flange 2 to the shaft 1 or vice versa. To disengage this clutch, a pressure medium is force-fed to the cylinder chamber 9 through a flow passage 22 to thereby slide the outer cylinder 6 rightward to cancel the clamping action of the tension plate 4.
