To improve stability of motion of a multistage roller transmission by restraining respective rollers from dispersing in the axial position.

An outside diameter side regulative means 4a for regulating an outer ring 2 of the second roller 3b to make a relative movement in the axial direction is provided near the contacting ends of the outer ring 2 and a second roller 3b. The outside diameter side regulative means 4a is composed of a pair of regulative faces provided on the outer ring 2 and restrains the second roller 3b respectively from both axial sides by making both end faces of the second roller 3b contact and interfere with the regulative faces.
