That is, in order to transmit torque between the universal joints 2 and 4, a lemon-shaped large-diameter tube 8 is connected to the yoke 6 of the universal joint 2, and a lemon-shaped small-diameter tube 8 is slidably fitted inside the lemon-shaped large-diameter tube 8. The tube 10 is connected to the yoke 12 of the universal joint 4. During rotation of the universal joints 2 and 4, the lemon-shaped large-diameter tube 8 and the lemon-shaped small-diameter tube IO slide against each other in the axial direction. 14.16
