Zusammenfassung:	PURPOSE:To provide a drive shaft excellent in oscillation property by making the rate of the weight of the coupling jointing to a pipe made of fiber reinforced resin and the weight of the pipe to 2 or less and the rate of the weight per unit length of the joint part of the coupling and the weight per unit length of the cylindrical part of the pipe to 2 to 8. CONSTITUTION:A drive shaft made of FRP comprises a pipe made of FRP and a metallic yoke 2 as a coupling, and a stub shaft 3 is used as a coupling. The joint part 4 of the yoke 2 and stub shaft 3 and the joint part of the pipe 1 are piled so that torque is transmitted. The ratio of the weight of either of the yoke 2 or the stub shaft 3 and the weight of the pipe 1 is made to 2 or less, while the rate of the weight per unit length of the cylindrical part of the pipe in the axial direction and the weight per unit length of the joint part 4 of the yoke 2 in the axial direction is made to 2 to 8. In addition, the rate of the length of the pipe 1 and the length from the supporting end 8 of the joint part 7 of the stub shaft 3 to the end part 6 of the pipe 1 is made to 6/1 to 10/1. Therefore, the amplitude of the vibration caused by the increase in the revolution of the drive shaft changes little.
