PURPOSE:To enable the use of a small sized nonstop variable speed gear through rotation at a high speed, by a method wherein an inclination plate is rotated in a sloped condition, a gear driving plate is laterally moved, and two spiral bevel gears are rotated in one-way. CONSTITUTION:A slide case 12 is mounted to a spline 20 of a driving shaft 1, a screw shaft 15 is rotated by a dial 17, and the slide case 12 is moved through a thrust bearing 13 by means of an arm 14. A pinion 16 is rotated by a rack 6 secured to the slide case 12 to incline an inclination plate 8, and a gear dividing gear 5 is laterally moved by a cam roller 7. Further, a spiral bevel gear 3 is rotated in one-way by means of a roller clutch 18, and transmis sion is effected from 0. This constitution enables a gear to be used through high speed rotation.
