The present invention relates to a roller for a conveyor. The roller is comprised of a driven section which is freely rotatably fitted on one end of a roller shaft supported in a frame. A sleeve member is provided which is freely rotatably supported on the one end through a seal device. A roller body is provided which is freely rotatably supported between the drive section and the other end of the roller shaft. An expandable and contractible flexible body is mounted on the sleeve member and is adapted to contact the inner surface of the roller body when contracted and when expanded to press against both the inner surface of the roller body and the driven section. A fluid feed is provided and a delivery passage is provided which opens to the interior of the flexible body for supplying fluid to the flexible body for expanding and contracting the flexible body. The fluid feed and the delivery passage expands from the rotatable shaft to the sleeve member.
