Abstract
A drum rotating device enables a drum and a driving device mounted in the drum to be supported with a simple structure and which reduces the possibility that the driving shaft of the driving device may be offset with respect to the rotation axis of the drum. The drum rotation device includes the drum and the driving device arranged to drive and rotate the drum. The drum includes an outer cylinder, an inner cylinder arranged inside the outer cylinder coaxially therewith, and a support wall arranged to connect the outer and inner cylinders to each other at an approximately intermediate portion in the axial direction. The outer and inner cylinders are substantially cylindrical. The driving device is fixed to a frame at one axial end. The driving shaft of the driving device extends through the drum and is rotatably supported by the frame through a bearing at the other axial end. The driving shaft is arranged to extend through the inner cylinder, thereby being fixedly attached the drum so that the drum and the driving shaft can rotate together.
