On the side, it is in a state of being placed on a return side belt bearing trough (hereinafter abbreviated as a return side trough) 20. The carrier-side trough 10 is formed in an arcuate shape or a semi-circular shape whose section is recessed downward, and has an injection hole 10 a and an air duct 12 for injecting upward compressed air supplied from a blower 30 which is a compressed air source at the lowermost portion. It is provided and forms a boundary film layer of compressed air between the lower surface of the belt 1 on which the transported goods are loaded and the carrier-side trough 10 to float the belt 1 while transferring the belt. A cover 7 for wind and rain prevention is laid on the upper side of the carrier-side trough 10 on which the belt 1 is placed. On the other hand, the return-side trough 20 is located below the carrier-side trough 10 and has a cross section formed in an arc shape or a semi-circular shape having an upward convex shape. Like the carrier-side trough 10, the return-side trough 20 has an injection hole 20a at the top. Injection hole 20
An air duct 22 for introducing compressed air to a is provided, and the belt 1b on the return side is floated and transferred. Also,
Both ends of the carrier-side trough 10 and both ends of the return-side trough 20 are connected by a pair of left and right side walls 8 to form a hermetically sealed structure inside.

Only the points different from FIG. 2 are described. The return-side trough 20 is formed in a semicircular shape like the carrier-side trough 10, and the radius thereof is the same as that of the carrier-side trough 10 or substantially the same. Instead of the air duct 22, a bottom plate 9 is provided on the lower surface of the return-side trough 20, and the space surrounded by the return-side trough 20 and the bottom plate 9 is used as a substitute for the air duct 22. In addition, the cover 7 is also the trough 1 on the carrier side.
The structure is made simpler by the flat plate suspended at both ends of 0, and the carrier side trough 10 and the return side trough 20 are manufactured using commercially available resin pipes or steel pipes, and the facility cost is greatly reduced. Is achieved (if the carrier side trough 10 and the return side trough 20 are used by cutting the same cylindrical tube into half sections, there is no waste and the material cost is low).
