PROBLEM TO BE SOLVED: To control the normal and reverse rotation speed of an output shaft only by changing the rotation speed of a control shaft with torque smaller than transmission torque for transmitting an output shaft from an input shaft. SOLUTION: The device is composed of a rotation speed control unit in which a rotation shaft 1 is connected to revolution shafts of a sun gear 7 and planetary gears 10, 11; a rotation shaft of planetary gear 6 is coupled with a planetary gear 8; revolution shafts of planetary gears 5, 6 and 8 are rotation shafts on the same line and connect a sun gear 4 and a control gear 15; and a control shaft 2 is connected to a control wheel 13 by a control gear 14 meshed with a control gear 15, and a rotation speed change rate amplifier in which a ring wheel 12 is connected to the revolution shafts of the planetary gears 5, 6 and 8 and an output shaft 3 is connected to a sun gear 9. In the device, the large-torque normal and reverse rotation speed of an output shaft 3 can be controlled only by changing the rotation speed of the control shaft 2 with torque smaller than that for transmitting the output shaft 3 from the input shaft 1 without changing rotative directions of the input shaft 1 and the control shaft 2.
