For convenience of illustration, in FIG. 2, the spiral filament 42 and the first spiral filament 47 and the second spiral filament 49, which will be described later in detail, are drawn in a ring shape. is also a helical striatum.

Both the link interval of the roller chain 2 and the rod pitch D ₁ of the spiral filament 42 (the interval between the intermediate positions of crests and valleys of the ribs 43) are set to 31.75 mm. In addition, the number of links of the roller chain 2 is set to 188, and the length of the conveying body 4, which is the sum of the stacking portion 41 and the connecting portion 46, in the traveling direction is set to 5969 mm.

The connecting portion 46 includes a first spiral filament 47 continuously attached to the ribs 44 at one end of the loading portion 41 in the traveling direction, and a spiral filament at the other end in the traveling direction of the loading portion 41 . and a second helical filament 49 continuously attached to the connecting portion force rib 45 passed through the connecting portion force rib 42 and having both ends fixed to both ends of the connection portion force rib 45 .

On the other hand, the portion inserted into the spiral filament 42, that is, the portion between the pair of roller chains 2, is set to have a diameter of 6 mm, which is larger than the inner diameter of the rollers 21a and the like. The ends 32 of the stay pins 31 protrude outward from the roller chains 2, and through holes 33 perpendicular to the axial direction formed in each of the ends 32 are provided with holes longer than the through holes 33. A split pin 34 is inserted. In this manner, the stay pin 31 and the roller chain 2 are attached so that the roller chain 2 can be attached to and detached from the stay pin 31 and is prevented from coming off, and the stay pin 31 cannot be pulled out from the roller chain 2 side. It is Further, the stay pins 31 are arranged in the same configuration every four links with reference to the connecting stay pins 35 arranged in the connecting portion 46 as will be described later.
