Therefore, when the input shaft 6 rotates in the direction of arrow C in FIG. 4 in this state, the carrier 22 integral with the input shaft 6
Also rotates in the direction of arrow C. In this case, since the internal gear 32 does not rotate, when the shaft 24 moves in the direction of arrow C together with the carrier 22, each planetary gear 23 rotates in the direction of arrow D. That is, each planetary gear 23 revolves in the direction of arrow C and rotates as shown by arrow D. Therefore, the large-diameter sun gear 12 meshing with each planetary gear 23 is accelerated by the input shaft 6 together with the output shaft 8 to rotate in the direction of arrow E.

Now, assuming that the number of teeth Z 1 of the large-diameter sun gear 12 is 46 and the number of teeth Z 3 of the internal gear 32 is 80, the speed increasing ratio R 1 of the output shaft 8 with respect to the rotation of the input shaft 6 is , Is expressed by the following equation. R 1 = (Z 1 + Z 3 ) / Z 1 = (46 + 80) /46=126/46≈2.74 That is, the speed increasing ratio in this case is 2.74 times.

Next, referring to FIG. 3, the midpoint of the shifter 34.
When 34a is set to the b position, the internal gear 32 at this time is in a state of not meshing with any gear as shown in FIG. Therefore, in this case, the rotation of the input shaft 6 is transmitted to the output shaft 8 via the one-way clutch 9 at a ratio of 1: 1.

Also in FIG. 3, the midpoint 34 of the shifter 34
When a is set to the c position, the internal gear 32 is brought to the position shown in FIG. 7 and meshes with the planetary gear 27 at this time. Since the planetary gear 27 meshes with the small-diameter sun gear 14, in this state the input shaft 6
When the carrier 22 rotates via the arrow F in FIG.
And revolves in the direction of arrow G. Therefore, the small-diameter sun gear 14 meshing with the planetary gear 27 is accelerated and rotated in the direction of the arrow H together with the output shaft 8.
