The gap 14 between the end portions 12a and 12b of 12 is the supply port 37.
It serves as an outlet for the cushion fluid supplied from 37, and the cylindrical collar 15 prevents the outflow fluid from scattering due to centrifugal force. The fluid cushions in the divided pipe bodies 12 ... 12 generate independent supporting pressures for the respective pipe bodies due to the rotation of the rod-shaped material 22, so that the rod-shaped material is supported by a plurality of supports as shown in FIG. 6 (a). The rod-shaped material 22 is supported at the center P ... P, the support of the rod-shaped material 22 by the fluid cushion is more stable, and whirling is prevented, and the shocking pressure generated in the fluid cushion connects the pipes 12 ... 12. Material to be opened in the part gap 14
Since the vibration of 22 is reduced from propagating to the guide tube 6, noise and vibration during rotation are reduced. It should be noted that FIG. 6 (b) schematically shows the supporting pressure of a conventional guide tube composed of a single tubular body. Further, since the length of the tube body 12 can be reduced, the guide tube 6 can be easily replaced when the diameter of the material 22 is changed, and the removed tube body 12 can be easily handled and stored. Further, by appropriately adding or removing the tube body 12 as a unit, it is possible to easily change the total length of the guide tube, and it is possible to cope with the change of the length of the material 22.
