Verfahren zur Herstellung einer Leistungsübertragungsvorrichtung

摘要

An object of the present invention is to provide a method for manufacturing a power transmitting apparatus which can well mold both the pressure-contact assisting cam and back-torque limiting cam even though either one of the pressure-contact assisting cam and back-torque limiting cam is molded as a reverse-draft surface. According to the present invention, there is provided a method for manufacturing a power transmitting apparatus comprising a clutch housing 2; and a clutch member 4 connected to an output member 3 and having a plurality of driven clutch plates 7 alternately arranged between the driving clutch plates 6 of the clutch housing; in which the pressure plate 5 and the clutch member 4 are respectively formed with through windows 5c and 4c at positions corresponding to the pressure-contact assisting cams 4aa and 5ba and the back-torque limiting cams 4ab and 5bb so as to form reverse-draft surfaces of the pressure-contact assisting cams 4aa and 5ba and the back-torque limiting cams 4ab and 5bb by inserting pin-shaped cores into the windows 5c and 4c.
