摘要： Cooling mechanism of a pulling clutch having the following construction: the outer periphery of the surface of an outer peripheral ring-like portion (12) on the side opposite to a fly wheel is supported by a clutch cover (9) through a wire ring (10) and the inner periphery of the surface on the fly wheel side is supported by a fulcrum projection (14) of a pressure plate (7). A ring-like holder (13) which covers the outer peripheral portion (12) on the side opposite to the fly wheel is disposed by utilizing window holes (15) of a diaphragm spring (11) having slits (16) which extend in the central direction from a plurality of positions of the inner periphery of the outer peripheral ring-like portion (12) through the window holes (15). A leg plate (23) extends from the inner periphery of this ring-like holder (13) towards the fly wheel (1) through the window hole (15) and is fastened to the pressure plate (7). A vane plate (26) extends from the inner periphery of the holder towards those remaining window holes (15) and pressure-feeds air into the window holes (15) during rotation. A stopper (27) extends from the outer periphery of the holder towards the diaphragm spring (11) to restrict the movement of the pressure plate (7) towards the fly wheel (1) when a clutch cover assembly (6) is a single body.
