Similarly, in a belt-driven roller conveyor, a drive pulley that is pivotally supported on a frame is rotated by a motor via a speed reducer to rotate a drive belt, and a large number of conveyors are connected in parallel on this drive belt. The conveying force is obtained by rotating the rollers through contact with the drive belt.

[0004] Also, in pusher devices, like the belt conveyor and chain conveyor described above, a drive pulley and a drive sprocket that are pivotally supported on a frame are rotated by a motor via a speed reducer, thereby rotating a drive belt and a drive chain. The conveyance force is obtained by moving a pusher connected to this drive belt or drive chain.

In conveying devices such as conveyors and pusher devices, the motor and reducer are installed at the bottom of the frame, and the output shaft of the reducer and the shaft of the drive pulley or drive sprocket are connected to the transmission sprocket or the endless drive sprocket. Since they are connected via a transmission mechanism such as a transmission chain, there are many parts, and there is a problem that noise is generated from the transmission sprocket and the transmission chain during driving.

[Problems to be Solved by the Invention] As described above, in the conventional conveying device, the motor and the reducer are provided at the lower part of the frame, and the output shaft of the reducer and the shaft of the driving rotary body are connected to the transmission sprocket and the endless shaft. Since they are connected via a transmission chain, there are a large number of parts, and there are problems in that noise is generated from the transmission sprocket and the transmission chain during driving.

[0007] The present invention has been devised in view of these points, and aims to reduce the number of parts of a conveying device and reduce the noise generated from the drive section.
