0 and is further transmitted to the driven shaft 10 via the outer race 11. Driven shaft 10 relative to drive shaft 14
is downward to the left in Fig. 1, the upper ball 20
moves in the direction in which the gap between the grooves 13 and 19 widens, that is, to the right.

The first cage 21 is pushed by the lower ball 20 and tilts clockwise. The movement of the lower ball 20 is restricted at the position where it is vertically sandwiched between the groove work 3 and the groove work 9, that is, the position where the rotation of the drive shaft 14 and the driven shaft 10 is at the same speed. The movement of the upper ball 20 is restricted through the cage 22. Conversely, the drive shaft 14
On the other hand, when the driven shaft 10 is tilted upward to the left in FIG. 1, the lower ball 20 moves in the direction in which the gap between the grooves 13 and 19 widens, that is, to the right. As a result, the second cage 22 is pushed by the lower ball 20 and tilts counterclockwise, and the upper ball 20 is pushed by the second cage 22 and moves to the left.
