  By the way, since the clip having the above-described configuration does not have a function of fixing the pipe in the axial direction and the rotation direction, the attachment position with respect to the pipe is not fixed. For this reason, for example, when the pipe is transported, the clip is greatly deviated from the original attachment position, and there is a problem that the clip needs to be moved greatly when the pipe is fixed at a predetermined position.

  The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a pipe clip capable of fixing an attachment position to a pipe and a pipe positioning structure using the pipe clip. And

The clip for a pipe of the present invention is a clip for a pipe attached to a metal pipe that is bent in advance or made of resin, and a pipe fitting portion that is fitted on the outer peripheral side of the pipe includes the pipe. Among these, a shape along the outer peripheral surface of the bent portion bent into a predetermined shape can be attached to the bent portion.

  According to the present invention, since the clip is not displaced in the axial direction and the circumferential direction with respect to the pipe, the attachment position with respect to the pipe can be fixed.

  As shown in FIG. 7, the two clips 10 mounted on the first coupling component 30F are positioned in a direction in which the bending directions coincide. Further, the two clips 10 attached to the first coupling component 30F are arranged substantially in parallel with each other by the height of the inner and outer peripheral walls 35U and 35S. Thus, the bent portions 40M of the two shield pipes 40F, 40S are arranged in parallel by the clip 10 and the first coupling component 30F so as to be substantially parallel to the bending direction and substantially perpendicular to the bending direction.

As shown in FIG. 11, the two clips 10 attached to the second coupling component 30S are arranged slightly apart in the inner and outer directions in the direction in which the bending directions coincide with each other, and are positioned substantially in parallel. Thus, the bent portions 40M of the two shield pipes 40F and 40S are arranged substantially in parallel by the clip 10 and the second coupling component 30S. The second coupling component 30S can be used instead of the first coupling component 30F in accordance with the layout of the shield pipe 40.

  Further, by changing the directions of the first coupling component 30F and the second coupling component 30S, the alignment direction of the two shield pipes 40F and 40S can be changed by 90 degrees. That is, as shown in FIG. 8, if the first coupling component 30F is disposed vertically (the mounting surface 33 is perpendicular), the two shield pipes 40 are arranged in the horizontal direction, and the first coupling component 30F is arranged. Are disposed sideways (in which the mounting surface 33 is horizontal), the two shield pipes 40 are arranged in the vertical direction. As shown in FIG. 12, if the second coupling component 30S is arranged vertically (the mounting surface 33 is perpendicular), the two shield pipes 40 are arranged in the vertical direction, and the second coupling component 30S is placed horizontally. If arranged in the direction in which the mounting surface 33 is horizontal, the two shield pipes 40 are arranged in the horizontal direction.

In the pipe clip 10 of the present embodiment, the pipe fitting portion 11 that is externally fitted to the shield pipe 40 is bent along the outer peripheral surface of the bent portion 40M that is bent into a predetermined shape of the shield pipe 40. It can be attached to the portion 40M. According to this configuration, since the clip 10 is not displaced in the axial direction and the circumferential direction with respect to the shield pipe 40, the attachment position with respect to the shield pipe 40 can be fixed.

  Moreover, the pipe fitting part 11 is formed in a pair of division body 15F, 15S which pinches | interposes the shield pipe 40 and unites | combines. According to this configuration, the clip 10 can be easily attached to the bent portion 40M of the shield pipe 40 by sandwiching the shield pipe 40 between the pair of divided bodies 15F and 15S and closing the divided body.

  The pair of divided bodies 15 </ b> F and 15 </ b> S are integrally connected by the hinge 21. According to this structure, since a pair of division body 15F, 15S can be handled integrally, it can handle easily compared with the case where a pair of division body 15F, 15S is separated.

  In addition, the pair of divided bodies 15F and 15S has a locking portion 22 that locks with each other when the split bodies 15F are combined. According to this configuration, when the pair of divided bodies 15F and 15S are combined, the locking portion 22 is locked. For example, after the pair of divided bodies are combined, an operation of separately fixing them so as not to be separated is performed. The clip 10 can be easily attached as compared with the case where it is performed.

  In addition, the pipe positioning structure of the present embodiment includes two clips 10 and a coupling component 30 that can couple the two clips 10. According to this configuration, since the two clips 10 are positioned with respect to each other by the coupling component 30, the two shield pipes 40F and 40S can be relatively positioned.

  In addition, two types of connecting parts 30F and 30S having different shapes are provided. According to this configuration, since the layout of the shield pipe 40 can be changed by changing the coupling components 30F and 30S, the degree of freedom in pipe layout can be increased.
