Claims

[Scope of Claim for Utility Model Registration] In a power transmission shaft consisting of a cylindrical shaft body made of fiber-reinforced plastic and a yoke having a cylindrical part fitted over the outside of the end of the shaft body, on the peripheral wall of the shaft body, A plurality of pin through holes are formed at predetermined intervals in the circumferential direction, a pin with a head is passed through the pin through holes from the outside, and the pin is inserted into the cylindrical part of the yoke.
A slit into which the head of the pin is tightly fitted is formed from the end on the shaft body side, a tapered male thread is formed on the outer surface of the cylindrical part of the yoke, and a tapered female thread is screwed into the tapered male thread. A power transmission shaft screwed into the cylindrical portion of the yoke such that a tightening ring having a hole is located outside the pin head and prevents the pin from coming out of the through hole.
