For example, the types of separator members include a so-called straight tube separator member that is arranged in a straight protective tube main body, and a so-called curved tube separator member that is arranged in a curved protective tube main body. and a separator member.
In a plan view of the straight pipe separator member, two main body through-holes are formed at the ends of the straight pipe separator member in the axial direction. The two body through-holes are spaced apart from each other with the center axis of the separator member in the width direction interposed therebetween.
A rivet (shaft-shaped member) is placed in each body through hole of the straight pipe separator member and in a joint through hole (through hole) formed in the separator joint to connect the straight pipe separator member and the separator joint.

On the other hand, in a plan view of the curved pipe separator member, three main body through holes are formed at the ends of the curved pipe separator member in the axial direction. One of the three main body through-holes is arranged on the central axis passing through the center of the bent pipe separator member in the width direction and along the axis, and the remaining two main body through-holes are arranged with this central axis between them. They are placed on both sides with a space between them.

The bent pipe separator member 60B is configured in the same manner as the bent pipe separator member 60A. That is, three main body through-holes 61, 62, 63 are formed at the ends in the tube axis direction X of the bent tube separator member 60B.
The separator joint 35 and the bent pipe separator member 60B are connected in the same manner as the separator joint 35 and the bent pipe separator member 60A.

In the conventional separator joint, as the number of through-holes formed in the joint wall increases, the strength of the joint wall generally decreases and the processing cost for forming the through-holes increases. For this reason, forming many through-holes in the separator joint has not been considered.

According to the separator joint 35 of this embodiment, the joint wall 40 of the separator joint 35 is formed with 10 through holes. through holes are used. That is, in a mode in which the straight pipe separator members 15A and 15B are connected to each other via the separator joint 35, for example, out of ten through holes formed in the joint wall 40, two joints are used for connection with the straight pipe separator member 15A. Through holes 43B and 44B are used, and two joint through holes 43C and 44C are used for connection with the straight pipe separator member 15B, for a total of four through holes.
In a mode in which the straight pipe separator member 15B and the bent pipe separator member 60A are connected via the separator joint 35, for example, out of ten through holes formed in the joint wall 40, two are used for connection with the straight pipe separator member 15B. Two joint through-holes 43B and 44B are used, and three connecting through-holes 42A and joint through-holes 43A and 44A are used for connection with the bent pipe separator member 60A, for a total of five through-holes.
In a mode in which the curved pipe separator members 60A and 60B are connected to each other via the separator joint 35, three of the ten through holes formed in the joint wall 40 are used for connection with the curved pipe separator member 60A. A hole 42A and joint through-holes 43A and 44A are used, and three connecting through-holes 42B and joint through-holes 43D and 44D are used for connection with the bent pipe separator member 60B, for a total of six through-holes.

A rivet 50 is placed in the through hole of the separator joint 35 used for each separator member 15,60. Through this rivet 50, the separator joint 35 is connected to the separator members 15,60.
As described above, the separator members can be connected to each other using the six through holes formed in the joint wall 40 regardless of the manner in which the separator members are connected to each other. Specifically, by using the six connecting through holes 42A, 42B and the joint through holes 43A, 44A, 43D, 44D, the separator members can be connected to each other regardless of the type of the separator member, such as for straight pipes or for curved pipes. can be done. Therefore, a pair of separator members can be connected via the separator joint 35 regardless of the type of separator member.

Since a pair of separator members can be connected by the separator joint 35 regardless of the type of separator member, the productivity of the separator joint 35 can be improved and the manufacturing cost of the separator joint 35 can be reduced.
By forming the separator joint 35 by injection molding, even if the number of through-holes formed in the joint wall 40 increases, it is possible to suppress an increase in the manufacturing cost of the separator joint 35 .

A connecting through-hole 42 is arranged on the central axis O<b>1 of the joint wall 40 . When the joint wall 40 is arranged so that the first direction D is parallel to the width direction Y of the bent pipe separator member 60A in plan view, the inside of the main body through hole 61 of the bent pipe separator member 60A and the separator joint 35 Identical rivets 50 are placed in the center through-holes 62A, respectively. As a result, in a plan view of the joint wall 40, for example, when the separator joint 35 and the bent pipe separator member 60A are arranged coaxially, the separator joint 35 and the bent pipe separator member 60A are arranged on the same axis with the central axis O1 as an axis of symmetry. They can be arranged substantially symmetrically in one direction D, respectively. Therefore, the shapes of the separator joint 35 and the bent pipe separator member 60A on each side in the first direction D with respect to the central axis O1 can be made more equal, and the usability of the separator joint 35 and the bent pipe separator member 60A can be improved.

The joint through-holes 43 and 44 are arranged so as to be symmetrical with respect to the central axis O1. The rivet 50 arranged on the first side in the first direction D and the rivet 50 arranged on the second side in the first direction D with respect to the central axis O1 are arranged substantially symmetrically with the separator joint 35 and the separator member 15. Therefore, the workability of connecting the rivets 50 to the separator joint 35 and the separator member 15 can be improved.

The ten through-holes formed in the joint wall 40 include a configuration in which four through-hole clusters 45, which are sets of two through-holes, are spaced apart from each other in the second direction E. As shown in FIG.
For example, in a mode in which the straight pipe separator members 15A and 15B are connected to each other, of the four through-hole aggregates 45 arranged in the second direction E, two through-hole aggregates 45A and 45B adjacent to each other in the second direction E Either one is used to connect the straight pipe separator member 15A and the separator joint 35 .
Then, the straight pipe separator member 15B and the separator joint 35 are connected by using one through-hole assembly 45C adjacent to the through-hole assemblies 45A and 45B in the second direction E. As a result, the straight pipe separator members 15A and 15B are connected to each other via the separator joint 35 .
By selecting through-hole assemblies 45A and 45B adjacent to each other in the second direction E as the through-hole aggregates used for connecting the straight-pipe separator members 15A, the straight-pipe separator members are connected through the separator joints 35. The distance in the second direction E between 15A and 15B can be adjusted.

The ten through-holes formed in the joint wall 40 include a configuration in which four through-hole aggregates 45 are spaced apart from each other in the second direction E. As shown in FIG.
For example, in a mode in which the straight pipe separator members 15A and 15B are connected to each other, of the four through-hole aggregates 45 arranged in the second direction E, two through-hole aggregates 45A and 45B adjacent to each other in the second direction E , the straight pipe separator member 15A and the separator joint 35 are connected. Then, another two through-hole assemblies 45C and 45D adjacent to the through-hole assemblies 45A and 45B in the second direction E are used to connect the other straight pipe separator member 15B and the separator joint 35 . As a result, the straight pipe separator members 15A and 15B are connected to each other via the separator joint 35 .
The through-hole assembly 45 used for connecting the straight pipe separator members 15A is selected from two through-hole assemblies 45A and 45B adjacent in the second direction E, and the through-holes used for connecting the straight pipe separator members 15B are selected. By selecting the assembly 45 from another two through-hole assemblies 45C and 45D adjacent to each other in the second direction E, the straight pipe separator members 15A and 15B connected via the separator joint 35 can be arranged in the second direction E. The distance can be adjusted over a wider range.

Further, according to the separator system 55 of the present embodiment, the separator system can be configured using the separator joint 35 that can connect a pair of separator members regardless of the type of separator member.
