PROBLEM TO BE SOLVED: To realize a structure capable of suppressing the deflection of a connecting member that causes aggravation of NVH when a connecting rod transmits a torque.SOLUTION: A connecting rod 15 that constitutes a crank mechanism of a continuously variable transmission includes an annular one end portion 15a rotatably supported by an outer circumferential surface of an input portion via a bearing 16; the other end portion 15b connected to a rock link 18; a first connecting portion 15c and a second connecting portion 15d connecting the one end portion 15a to the other end portion 15b; and a hollow portion 15e surrounded by the first connecting portion 15c and the second connecting portion 15d, a connecting member 30 is provided in the hollow portion 15e to be connected to the first connecting portion 15c and the second connecting portion 15d so as to partition the hollow portion 15e into a plurality of regions, a portion of the connecting portion 30 connected to the first connecting portion 15c differs in rigidity from a portion thereof connected to the second connecting portion 15d, and the rigidity of the connected portion on a side on which the bearing 16 supporting the one end portion 15a receives a maximum load is set high with respect to a line connecting a center of the one end portion 15a to a center of the other end portion 15b. |
