PURPOSE:To finely adjust the speed of a running unit, by forming and surfaces of discs of input and output shafts to a circular arc shape, adapting idlers between the discs and optionally changing an angle of the idlers. CONSTITUTION:Discs 6, 8, provided with circular arc shaped end faces 5, 7, are mounted respectively at a face-to-face position to an input shaft 4 and output shaft 11. Idlers 9, rotatably supported by supporting shafts 10, are adapted between the circular arc shaped end faces, 5, 7. An angle of the supporting shafts 10, formed with the input and output shafts 4, 11, is optionally changed to perform speed change of the output shaft 11. |
