The present invention is to provide a clutch device that keeps a half-clutch range wide for a long time. A clutch device 1 is arranged in such a manner that an intermediate ring 24 is disposed on the pressure plate 23 so as to be slightly movable in a direction of pressing by a diaphragm spring 21; air passageways 31 are radially disposed at regular circumferential intervals between the intermediate ring 24 and the pressure plate 23 so as to let the inner and outer peripheries communicate with each other; plate springs 25 are disposed in the air passageways 31 to bias constantly the intermediate ring 24 and the pressure plate 23 in a direction of separating from each other; and a force of the pressing operation by the diaphragm spring 21 is transferred to the pressure plate 23 via the intermediate ring 24 and the plate springs 25.
