That is, the eleventh and second output members 43 and 44 rotate in the same direction and at the same speed, and the vehicle moves straight. Next, as shown in FIG. 6, when the first input member 51 is rotated counterclockwise at a speed H and the second input member 54 is rotated at a speed M, the ring gear 61 of the first planetary device 60 is driven at an increased speed. At P, the sun gear 41 of the second planetary device 30 rotates counterclockwise at a reduced speed R. That is, since the rotational speeds of the first and second output members 43 and 44 are different, the vehicle turns. Although not shown in the figure, when the first input member 51 is held stationary and only the second input member is driven to rotate, the first and second output members rotate in opposite directions at the same speed, and the vehicle turns on the spot. .
