PROBLEM TO BE SOLVED: To provide a stepless speed change device capable of reducing a load onto a bearing by restraining vibration.SOLUTION: A stepless speed change device 1A comprises a mechanism 23A for adjusting a distance between input and output shafts to adjust a distance Lp between a rotation center axial line P1 of an input part 2 and a rotation center axial line P4 of an output shaft 3 while an oscillation link 18 is transmitting a driving force to the output shaft 3. When the oscillation link 18 does not transmit the driving force to the output shaft 3, conditional expressions (1) and (2) are satisfied. In the expressions, Lcon is a distance between an input side fulcrum P3 and an output side fulcrum P5, R1 is a distance between the rotation center axial line P1 of the input part when a rotation radius of a rotation radius adjusting mechanism 4 is a predetermined rotation radius and the input side fulcrum P3, and R2 is a distance between the rotation center axial line P4 of the output shaft 3 and the output side fulcrum P5. |
