Abstract
A mold for manufacturing a composite drive shaft, most of which, except for opposite ends functioning as power transmission parts, has a tubular shape with a circular cross-section similar to that of a general shaft, and the shape of each end of which is changed so as to realize easy removal of the drive shaft from the mold after molding. Further, the present invention provides a composite drive shaft, which is manufactured using the mold and is configured such that, when a connection joint (metal yoke) is assembled with each end of the drive shaft, the drive shaft can be rotated in an integrated state realized by the connection joints. Thus, the composite drive shaft of the present invention can directly transmit power, instead of a mechanical fastening jointing technique or an adhesive bonding jointing technique, thus efficiently transmitting high torque.
