PROBLEM TO BE SOLVED: To obtain a large speed reduction ratio from a small-sized device. SOLUTION: This transmission fixes an input/output disk 14, 17 respectively to an end part of an input shaft 6 and an output shaft 7. An input/output friction surface 15, 31, having respectively a cone protruded surface, is friction engaged. A plurality of generating lines related to the output friction surface 31 are crossed in a point (a) on a center lineβof the output shaft 7. On the contrary, a plurality of generating lines related to the input friction surface 15 are crossed in a point (b) in a side of the input disk 14 from the center lineβ. |
