PROBLEM TO BE SOLVED: To improve the rigidity of an input shaft 2 of an infinite variable transmission.SOLUTION: An infinite variable transmission comprises: an input shaft 2; a plurality of lever crank mechanisms converting a rotational motion of the input shaft 2 to a swing motion of a swing link pivotally supported by an output shaft; and a one-way-rotation prevention mechanism. The lever crank mechanisms each include a radius-of-rotation regulation mechanism; and a connecting rod connecting the radius-of-rotation regulation mechanism to the swing link. The radius-of-rotation regulation mechanism includes cam disks 5 arranged decentered from a rotation center axis of the input shaft 2. The cam disks 5 of the adjacent lever crank mechanisms are coupled together to constitute the input shaft 2. A connection hole 103 connected by a connecting bolt 101 is provided in each cam disk 5 at a position of half of a phase difference α from the cam disk 5 adjacent to the cam disk 5 on one side in an axial direction. Furthermore, a connection hole 104 connected by the connecting bolt 101 is provided in each cam disk 5 at a position of half of a phase difference &bgr; from the cam disk 5 adjacent to the cam disk 5 on the other side in the axial direction. |
