PROBLEM TO BE SOLVED: To provide an infinitely variable transmission which enhances transmission efficiency of a frictional engagement part and can output larger torque while increase in volume and weight is constrained. SOLUTION: The transmission is disposed at predefined interval by a carrier 42 located between axially movable wheels 30, 32. It has a first and a second raceway surface 40a, 20b which are respectively formed on tapered end and frictionally engage on a circular engagement parts 30a, 32b of each wheel. It is provided with a plurality of rolling elements 40 which axis of rotation r through the center of the raceway surfaces is located radially inwards of the engagement part. It is also provided with a plurality of oscillating axes 44 which are pivotably secured to the carrier 42 by extending to direction orthogonal to the axis of rotation and rotatably carry each of the rolling element 40 by centering the axis of rotation r and pivotably carry the axis of rotation r relative to central axis C of the engagement parts 30a, 32b. Each of the rolling element 40 rotates the other wheel 32 in accordance with axial position of each of the wheel when both distance of engagement position Ka, Kb of the engagement parts on each of the raceway surface and the axes of rotation r are established and the rolling element is rotatably driven by one wheel 30 and the carrier 42.
