Abstract: A power transmitting apparatus, which can simultaneously achieve radial size reduction and improve strength of the driving clutch plate, has a clutch housing (2) and a plurality of driving clutch plates (6) each having projections (6a) projecting radially outward from the periphery of the driving clutch plate (6). The projections (6a) engages the clutch housing (2) to rotate with it. A clutch member (4) has a plurality of driven clutch plates (7) alternately arranged between the driving clutch plates (6). A pressure plate (5) is provided to carry out the pressure-contact or release of the driving clutch plates (6) relative to the driven clutch plates (7). Each of the driving clutch plates (6) has a peripheral surface (?), a projected wall surface (?), of the projections (6a), and a connecting surface (?). Each connecting surface (?) connects the projected wall surfaces (?) and the peripheral surface (?).

Abstract: A power transmitting apparatus which can reduce the number of parts in the apparatus and simplify the structure of the apparatus and thus reduce the manufacturing cost of the apparatus as well as reduce the size of the apparatus when compared with its torque transmitting capacity. The apparatus has a clutch housing (2), a clutch member (4), a pressure plate (5), stopper portions (5b) each fitting in a recess (4a) formed on the inner peripheral wall of the clutch member (4) and limiting the rotation of the pressure plate (5).
