ABSTRACT:
A propeller shaft including an FRP tube and joints connected to at least one end of said FRP tube. The FRP tube includes cylindrical end portions into which cylindrical portions of the joints are press-fitted, and intermediate tubular portions which have tapered inner peripheral surfaces connected at their large-diameter ends to terminal ends of inner peripheral surfaces of the cylindrical end portions and which are formed by a helical winding. The intermediate tubular portion is formed as a portion which is to be broken upon collision of the vehicle, and the cylindrical portion of the joint is formed as a breaking member which is adapted to collide against the tapered inner peripheral surface of the intermediate tubular portion by sliding under a shock load. In this way, a propeller shaft can be provided which is capable of absorbing a shock load upon collision of the vehicle.
