Abstract
A power transmission shaft to be used mainly in vehicles comprises metal joint elements and a metal pipe connected to each other. A fiber reinforced plastic pipe having a large flexural modulus of elasticity is inserted into the metal pipe, thus forming a composite FRP shaft having flexural rigidity sufficient to serve as a power transmission shaft.
