易な駆動ローラコンベヤとすることができる。As described above, in the drive roller conveyor of the present invention, the first high friction roller having a large frictional resistance, which is in contact with the drive roller, is fixed to the other end of the plurality of conveying roller shafts at the head and tail. At the same time, the second high friction roller is fixed to one end side of the shaft of each conveyance roller, and further elastically abutted on the two second high friction rollers adjacent to the inside of one frame. Since the interlocking rollers are arranged, it is possible to smoothly convey the object to be conveyed by synchronously rotating the respective conveyance rollers via the interlocking roller and the second high friction roller of the adjacent conveyance roller shaft. Further, according to the present invention, since the flat belt is not used and the interlocking roller can be attached to the pressurizing state by the spring to rotate the conveying roller, there are few failures as compared with the belt driving conveyor, and any trouble is caused. The drive roller conveyor can be easily maintained without any adjustment.
