PROBLEM TO BE SOLVED: To provide a small stepless continuously variable transmission capable of restraining costs.SOLUTION: A stepless continuously variable transmission 1 comprises: an input disc 5; an output disc 6 rotating around a rotation shaft non-coaxial with a rotation shaft of the input disc 5 as a center; and power transmission parts 7 having an input roller 12 contacting the input disc 5, an output roller 13 contacting the output disc 6, and a shaft 14 coupling the input roller 12 and the output roller 13. The speed is changed by changing a contact radius of the input roller 12 and the input disc 5 and a contact radius of the output roller 13 and the output disc 6. The stepless continuously variable transmission comprises gear change means 9 for changing the speed by inclining at least one of the power transmission parts 7, and moving the power transmission parts 7 between the rotation shaft of the input disc 5 and the rotation shaft of the input disc 6. |
