To achieve stable power transmission through friction between a driving roller (D) and a driven roller (S) and to miniaturize a power transmission mechanism, a power transmission roller according to the present invention is provided with: a roller body (2) contacting a driving roller (D) and a driven roller (S); a fulcrum shaft (3) fixed to the side of a cover (C); a roller bearing (5) rotatably supporting the roller body (2); a rocking arm (4) to which the fulcrum shaft (3) and the roller bearing (5) are attached and which has a displacement mechanism (8) enabling the fulcrum shaft (3) to be relatively moved in the radial direction of the roller bearing (5), rotates the roller bearing (5) around the fulcrum shaft (3), and is accommodated in the inner diameter side of the roller body (2); and a rocking drive member (6) which drives the rocking arm (4) to be rotated around the fulcrum shaft (3) and is accommodated in the inner diameter side of the roller body (2). |
