、となる。When the hub 1 rotates (twists) in the direction of arrow R relative to the facing 2, the internal roller 9 is fixed together with the brake 14 and the facing 2, so that the sun roller 6 rotates in the direction of the arrow R relative to the internal roller 9. As a result of the rotation (threading), each planetary roller 7 rotates ten times in the direction of arrow P, and also moves (transfers) the inner circumferential surface of internal roller 9 in the direction of arrow R. Planetary roller 7
As the carrier 8 moves in the direction of the arrow P, the carrier 8 also rotates in the direction of the arrow R at the same speed as the planetary roller 7. The rotation of the carrier 8 in the direction of arrow R is slower than the rotation of the sun roller 6 due to the planetary principle, and the rotation angle W of the carrier 8 is also smaller than the rotation angle W2 of the sun roller 6. . For example, the inner diameter of the internal roller 9 is C1, the outer diameter of the sun roller 6 is A
Then, the reduction A + OA angle ratio is -, and the rotation angle W1 of the carrier 8 is A + CXW.
