4.7 is bent at 1 as shown in Figure 444, and for the l'liJ return pipe 4, the bent inner part of the outer peripheral coating 6, 11) is in the radial/L' direction. The wave-shaped part 8 jumps out, and the visible tube 7 is also pushed out from the space 5 of 11 as shown in Figure 5. Also, the flexible tubes 4 and 7
In both cases, the engagement between the steel strips 1 becomes loose and they tend to come off as shown in Figure 446.

As a result, the flexible tubes 4 and 7 are bent between the main body of a machine tool and a spindle head on a slide table, or along the arm of a robot.
-1: Repetitive formation of wrinkles 8 ((Thus, in addition to tearing the outer peripheral membranes 6, 6, the darkness of the steel plate 1 becomes loose and the sheet is likely to come off, and the "double line" in the flexible tubes 4, 7 The object of the invention is to provide a side surface of a hard synthetic resin strip that is spirally wound to form a tube, and at least the outer surface that is in contact with the side surface. I
The object of the present invention is to eliminate the above-mentioned drawbacks of the conventional art by providing a synthetic resin flexible tube having an engaging surface that prevents the coating from moving in the radial direction.

(Structure of the invention) As shown in Figure 7, the present invention is an IC whose transverse direction is approximately S.
Made of hard synthetic resin in the shape of a letter ・The rod-shaped bodies 9fe are engaged with each other in the same direction and are wound spirally with IJ%.A dedicated synthetic resin is wrapped around the outer periphery of the R-shaped body 1Q between the stations of the band-shaped body 9. The outer coating 12 is formed by covering the part 11 with the shaped part filled in the part 11, and the outer coating 12 is fixed to the side surface of the strip 9 to prevent the outer coating 12 from moving in the radial direction. The engagement surface 16 is formed of a flexible tube made of synthetic resin.

Further, as shown in FIG. 8, the present invention has the same configuration as the flexible tube shown in FIG. It is a composite (!yJ resin flexible tube) which additionally forms an engaging surface 15 to prevent u'il.

Examples of the invention Figures 9j and 11 are examples of the first embodiment of the present invention,
A side surface of a hard synthetic resin strip 16 whose transverse direction is approximately S-shaped;

An outer frequency film 20 is formed.

When the flexible tube 21 formed in this manner is bent, an external force that causes the outer frequency coating 2° to protrude in the radial direction acts on the bent inner periphery of the outer frequency membrane 2o, but +! Since the outer peripheral coating 20 filled in the fifth portion 19 engages with the engagement surface 18 on the side surface of the strip 16, it does not protrude in the radial direction.

Therefore, even if the flexible tube 21 is bent, its outer periphery will not protrude and become unsightly.Furthermore, since wrinkles will not occur in the outer periphery coating, shortening of the life of the flexible tube 21 due to bending can be prevented. 21 rtli# durability can be significantly improved.

Next, FIG. 12 and FIG. 16 show two embodiments of the uninvented needles (in this case, they engage with the side surfaces of the strips 22 that engage with each other in the lateral direction to form a tube body 23). The engagement surface 24 is a hexagonal protrusion that prevents the radial movement of the strip 22. When the flexible tube 25 is bent, the engagement surface 18 of the first embodiment prevents the external coating 26 from moving in the radial direction. Belt-shaped body 2 with protrusion prevention

Next, FIGS. 14 and 15 show a sixth embodiment of the invention, in which the operation and effect are almost the same as the first embodiment described in @. On the side surface of the body 28, an engaging surface 29 having a semicircular cross section is formed with a retaining surface 6o having a hexagonal shape in the horizontal direction. Same as Japanese pressure.

Next, FIG. 16 shows a fourth embodiment of the present invention, and in this case, the belt-shaped body 61 is formed between the station areas 32 and 32. ? The outer frequency IN is formed so as to form a 5-shaped body, and is formed by engaging each other (also when the tube body 63 is bent).

Effects of the Invention The present invention provides an engagement 16 for preventing the radial movement of the outer H4 treatment membrane that is in contact with the side 1111 on the side surface of a hard synthetic resin strip that is spirally wound to form a tube body.
