A one-way clutch 17 in a stepless transmission 1 locks a swing link 18 to an output shaft 3 when a swing end 18a moves away from an input shaft 2. The distance Lcon between an input-side fulcrum P3 and an output-side fulcrum P5 satisfies the following conditional expression: Lcon<√(Lp2+R12−R22) where Lp is the distance between the rotational center axis P1 of the input shaft and the rotational center axis P4 of the output shaft, R1 is the distance between the rotational center axis P1 of the input shaft and the input-side fulcrum P3 when the amount of eccentricity of a rotational radius adjusting mechanism 4 is a predetermined value, and R2 is the distance between the rotational center axis P4 of the output shaft and the output-side fulcrum P5. |
