A supercharger has a step-up gear including an outer wheel which rotates with an input shaft and is eccentric from an output shaft, and a plurality of intermediate rollers to which are disposed in a ring-shaped space, of which the width in the diameter direction of the output shaft between the output shaft and the outer wheel is not constant in the circumferential direction of the output shaft. At least one intermediate roller is a movable roller which can moves in the circumferential surface and the radius direction of the output shaft. The outer wheel is closely fitted onto the outer circumferences of all the intermediate rollers and the inner circumferential surface of the outer wheel is brought into elastic contact with the outer circumferential surfaces of all the intermediate rollers.
