Abstract
A fiber reinforced plastic propeller shaft has a fiber reinforced plastic pipe, and at least one metal member attached to an end of the pipe. The metal member is provided with a serration having a plurality of teeth having an apex angle. When the metal member is attached to the end of the pipe, each tooth forms on the inner surface of the pipe end a groove extending along the axial direction of the pipe. The apex angle of each tooth is between 45° and 75°.
