Abstract
An FRP drive shaft includes an end joint joined to at least one end of an FRP cylinder via an outer collar. The end joint includes a serrated portion on an outer periphery thereof. The outer collar includes a small-diameter collar portion and a large-diameter collar portion. The serrated portion is press-fitted into an inner periphery of the FRP cylinder and fixed to an inner periphery of the small-diameter collar portion. A gap between an inner periphery of the large-diameter collar portion and an outer periphery of the FRP cylinder is filled with an adhesive for fixing the inner periphery of the large-diameter collar portion and the outer periphery of the FRP cylinder to each other. An adhesive-accumulating space which partially increases a filling amount of the adhesive is formed between the inner periphery of the large-diameter collar portion and the outer periphery of the FRP cylinder.
