Abstract:
1. A drum rotating device comprising: a drum arranged between a pair of oppositely positioned frame sidewalls; and a driving device including a motor arranged to drive and rotate the drum, the driving device being mounted in the drum; wherein the driving device is fixed to one of the frame sidewalls at one end in an axial direction of the drum; a driving shaft of the driving device is arranged to extend through the drum to project from the drum to another one of the frame sidewalls at another end in the axial direction of the drum, a projected portion of the driving shaft being rotatably supported to the other of the frame sidewalls through a bearing; the drum is fixedly attached to the driving shaft such that the drum is rotatable together with the driving shaft; the driving device includes a decelerator arranged to decelerate a rotation speed of the motor and to transmit the decelerated rotation speed to the driving shaft; a rotation shaft of the motor and the driving shaft are coaxial with each other; and the rotation shaft of the motor extends in the axial direction, a first axial end of the rotation shaft projects through the frame to outside of the frame, and a second axial end of the rotation shaft is connected to the decelerator.
