PURPOSE:To make a gear change possible even without a common separator by rotating a plurality of rotors arranged in planetary state with a power transmission means, and the first and second ration means. CONSTITUTION:A plurality of steel balls 13 are arranged like a planetary around a V-pulley 12 (power transmission means) fitted to a drive shaft 11 and revolve, while rotating, on the rotation of the pulley 12. The first and second rotation means 14 and 15 having inverted conical surface are arranged in such a way as clamping the steel balls 13 in an axial direction. In this case, the relative speed of the first and second rotation means 14 and 15 is (T/2)X(D2-D1)/R, provided that the effective radius of the steel balls 13 relative to the pulley 12 is R, the rotating speed of the pulley 12 is T, and the effective radii thereof relative to the means 14 and 15 are D1 and D2. Also, when the first rotation means 14 is fixed, the rotation speed of the second rotation means 15 becomes (T/2)X(D2-D1)/R. This rotation is obtained from a driven shaft 16. |
