PROBLEM TO BE SOLVED: To provide a roller transmission device and a drive force distribution device which are capable of suppressing generation of judder.SOLUTION: A roller transmission device transmits power between a first roller 31 and a second roller 32 by bringing outer peripheral surfaces 31a, 32a of the rollers 31, 32 into friction-contact with each other or traction-contact via an oil film with each other. In the roller transmission device, shapes of the rollers 31, 32 are determined so that relative speed distribution in contact areas of both of the rollers 31, 32 has distribution in which a relative speed in an opposite direction to each other arises. |
