The supply roll 46 is provided with the link shaft 58, (52) of the feed roll And the upper gear 80 is provided at the upper end of the vertical shaft 78. The bevel gear 62 is connected to the pair of supply rolls 46 And the rotation of the vertical shaft 78 is transmitted to the upper gear 80, the bevel gear 62 and the two supply roll teeth portions 52, So that the supply rolls 46 are driven to rotate through the bevel gears 62 by the rotation of the vertical shaft 78 so that the conventional universal ball unit (100) can deliver the effect of transporting the cargo (W).

However, the conventional conveying apparatus 30 and its universal ball unit 100 have the following defects.
