That is, the curvature does not change from the first bending portion 8 even in the vicinity of the end portion 7 of the support 2.
Even if the support 2 does not include the second bending portion 9 as in the flexible tube support 1b as shown in FIG. 2, it can function sufficiently as a flexible tube support.
In this case, in the support 2, the length of the mounting portion (space portion 3) of the flexible tube 20 excluding the portion attached to the hard conduit 18 is changed from the end portion 18 a of the hard conduit 18 to the base portion of the connector 21. The length of the cable 22 and the connector 21 are set so as to be substantially the same as or slightly shorter than the length of the cable 22 so that the distal end portion of the end portion 7 of the support 2 bites into the flexible tube 20. Further, it is possible to prevent an excessive load from being applied locally to the cable 22 and the flexible tube 20 that accommodates the cable 22.
In addition, the structural feature of the flexible tube support 1b according to the second embodiment is that only the first curved portion 8 is provided in the body portion of the support 2 and the second portion is provided in the vicinity of the end portion 7. The configuration in which the bending portion 9 is not provided can also be applied to supporters according to other embodiments described below.

In particular, in the flexible tube support 1b according to the second embodiment, the angle θ formed by the central axis at the end 6 of the support 2 and the central axis at the end 7 is in the range of 90 ° ≦ θ ≦ 270 °. By setting the inside of the flexible tube 18, the flexible tube 20 can be placed excluding the portion attached to the hard conduit 18 rather than the length of the cable 22 from the end 18 a of the hard conduit 18 to the connection base of the connector 21. Even when the length of the portion (space portion 3) is short, the end portion 7 can be prevented from biting into the flexible tube 20, and the cable 22 and the flexible tube 20 accommodating the cable 22 can be held in a stable state. it can.
Therefore, the flexible tube support 1b according to the second embodiment also has the same actions and effects as the flexible tube support 1a according to the first embodiment.

A flexible tube support according to Embodiment 3 of the present invention will be described in detail with reference to FIG. Fig.4 (a) is sectional drawing of the flexible tube support which concerns on Example 3 of this invention, (b) is sectional drawing which shows the use condition. (C) is a sectional view taken along line D-D in FIG. 4 (b). The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted. Further, here, description will be given with emphasis on the difference in action and effect due to the structural difference when compared with the flexible tube support 1a according to the first embodiment.
As shown in FIG. 4 (a), the flexible tube support 1c according to the third embodiment includes a support 10 for supporting the flexible tube 20 including the cable 22, and n (n ≧ 2, n Natural number) support pieces, for example, constituted by support pieces 11a to 11c, each support piece being an inner side 4 of the k-th support piece (1 ≦ k ≦ n−1, k is a natural number), The k + 1th (1 ≦ k ≦ n−1, k is a natural number) support piece 5 is laminated so as to be slidable while facing each other.

A hooking structure or a fitting structure may be provided.
More specifically, for example, as shown in FIG. 4 (c), streak-like grooves 13 parallel to the edges of the support 2 are formed on both side surfaces 23 of the outer sides 5 of the support pieces 11c and 11b. The protrusions 12 are formed at the edges of the support piece 11a and the support piece 11b and at the end on the side where the connector 21 is arranged so as to mesh with the concave shape of the groove 13 and both side surfaces of the support piece 11b. If the projections 12 formed on the support piece 11a are fitted into the groove portions 13 formed on the support pieces 11a, and the projections 12 formed on the support pieces 11b are fitted into the groove portions 13 formed on both side surfaces 23 of the support piece 11c. Good.
Instead of the protrusion 12, a protrusion (not shown) that fits into the groove 13 may be formed and fitted into the groove 13. Further, instead of the groove 13, a U-shaped or U-shaped rail is projected on both side surfaces 23 of the outer sides 5 of the support pieces 11c and 11b, and a projection 12 or a projection not shown is fitted into the recess. May be. Furthermore, you may reverse the attachment position of the groove part 13, the protrusion 12, or a protrusion.

In this case, when the support tool 10 is slid and the length thereof is adjusted, the support pieces (for example, the support pieces 11a to 11c) are separated from each other by providing the fitting structure or the hooking structure as described above. Can be prevented.
In addition, the rail body having the groove 13 or the concave structure formed or installed on both side surfaces 23 of the support pieces 11b and 11c is a guide when the support pieces (for example, the support pieces 11a to 11c) are slid. Therefore, the effect that the expansion / contraction operation of the flexible tube support 1c according to the third embodiment can be made smooth can also be expected.
