The tube holder 41 is prevented from moving (rotating) in the circumferential direction by contacting the base end (root) of the protrusion 51.

The inner surface of the end portion of the connecting holder 5, the upper and lower besides each pair of ridges 51, ridges 60 ₂ of each pair of upper left and right and lower left and right and is provided at a substantially uniform pitch, the rib 60 _2, the surface 60 a ₂ on the side close to the upper and lower ridges 51 is greatly inclined, the surface 60 c ₂ on the far side is raised with a steep slope, the surface 60 b ₂ on the protruding tip side is small, and the protruding proximal end (root) The side area 60d ₂ is formed large.

  For example, from the horizontal state (turning angle α1 = 0 °) of the tube holder 41 in FIG. 11, the connection holder 5 is opened with the hinge 58 (FIG. 12) as a fulcrum, and the tube holder 41 is slightly rotated clockwise as shown in FIG. It is inserted into the connection holder 5 in a rotated state (at a rotation angle α2 = 45 °), the connection holder 5 is closed, and the end of the tube holder 41 is held.

In this state, the upper and lower left protrusions 60 ₂ of the connection holder 5 are engaged between the pair of protrusions 51 of the tube holder 41, and the upper right protrusion 60 ₂ of the connection holder 5 is connected to the tube holder 41. engaged between the upper right of the pair of projections 51, the proximal end of the inner side surface 51c of the right protrusion 51 of the right end of the corner tube holder 41 of the ridges 60 ₂ of the projecting distal end face 60b ₂ of the connection holder 5 Abut. At the same time, the right corner of the protruding tip surface 60 b ₁ of the upper ridge 60 ₁ of the connection holder 5 abuts on the base end of the outer surface 51 d of the left ridge 51 of the tube holder 41. The same effect is exhibited in the lower left protrusions 51 and 60 ₂ . As a result, the tube holder 41 is held stationary at a position rotated 45 ° clockwise relative to the connection holder 5.

  From the pivot position (rotation angle α2 = 45 °) of the tube holder 41 of FIG. 12, the connection holder 5 is opened with the hinge 58 as a fulcrum, and the tube holder 41 is further rotated 45 ° clockwise as shown in FIG. 11 is inserted into the connection holder 5 while being rotated (at a rotation angle α3 = 90 ° from the state 11), the connection holder 5 is closed, and the end of the tube holder 41 is held.

In this state, the corners of the protruding tip surfaces 60b ₂ of the pair of left and right ridges 60 _{2 on} the upper side of the connection holder 5 are the outer surfaces 51c of the upper ridges 51 of the pair of left and right ridges 51 of the tube holder 41. At the same time, the corners (not shown) of the protruding distal end surfaces 60b ₂ of the pair of left and right protrusions 60 ₂ on the lower side of the connection holder 5 are paired with the left and right protrusions of the tube holder 41, respectively. It contacts the base end (root) of the outer surface 51 c of the lower protrusion 51 of the stripe 51. As a result, the tube holder 41 is held stationary at a position rotated 90 ° clockwise relative to the connection holder 5.

  In addition, when using connection holder 5 and tube holders 41 to 43 having an oval cross section corresponding to corrugated tube 2 having an oval cross section and the like instead of a circular cross section, each end of connection holder 5 and tube holders 41 to 43 is used. The protrusions 51 and 60 are arranged at an appropriate pitch, not at an equal pitch.

  By selecting the three types of tube holders 41 to 43 according to the configurations of the above-described vehicle cable exterior members 1 and 1 ′, the ends of the two tube holders selected at both ends of the connection holder 5 are connected and held. As a combination of two tube holders, a total of 12 combinations of holder assemblies (e.g., 71-1) including three times the four-way combinations of FIGS. 74) can be obtained, and in addition, the three angles of FIGS. 11 to 13 can be selected to obtain at least 36 combinations of holder assemblies in total.

  Thus, even if the vehicle type changes, the first bent portion (46, 54 in the example of FIG. 7) of the path before and after the bracket insertion fixing portion 11 of the connection holder 5 that is a fixing portion to the vehicle, and the destination of the bent portion The routing route up to the direction can be reproduced (assembled) with a three-dimensional degree of freedom and almost close to the ideal routing route.

  Thus, the path | route before and behind the vehicle fixing | fixed part 11 of the cable exterior members 1 and 1 'is three-dimensionally regulated by the tube holders 41 to 43, so that the bent portions of the tube holders 41 to 43 (in FIG. 7). In the example, the destination direction (extension direction) from 46, 54) becomes a lead to the next vehicle fixing portion (the bracket insertion fixing portion 11 and the connecting holder 5 including the same), and the mounting workability to the vehicle is improved.

  In addition, by restricting the route before and after the vehicle fixing portion 11, the number of setting of the vehicle fixing portion 11 can be reduced, the burden on the vehicle assembly operator can be reduced, and the wiring to the vehicle can be performed. The reproducibility of the route (layout) can be improved.

  Further, the corrugated tube 2 which is a flexible member compared to the hard tube holders 41 to 43 and the connection holder 5 is bent to fold the vehicle cable exterior members 1 and 1 ′, thereby obtaining a compact packaging form. it can. Moreover, since each tube holder 41-43 and the connection holder 5 have versatility for every size (diameter) of the corrugated tube 2, it is not necessary to start construction for every vehicle like the conventional protector (for example, refer patent document 2). Therefore, it is possible to develop the vehicle in various specifications, and it is possible to reduce the cost of the cable exterior members 1 and 1 ′.

  In the above embodiment, the vehicle cable exterior member 1, 1 ′ is described as being wired under the vehicle floor, but the vehicle cable exterior member 1, 1 ′ is not necessarily limited to the vehicle floor below. For example, it can be used on a vehicle floor by increasing the insulation of a high-voltage cable, and can also be applied for low-voltage cable routing instead of high-voltage cable.

  Moreover, in the said embodiment, although the tube holders 41-43 which have three types of bending angles (theta) 1-theta3 (FIGS. 3-5) were used, a bending angle is not restricted to three types, four types or more or more or Two types are also possible. Similarly, the circumferential rotation angles α1 to α3 (FIGS. 11 to 13) of the tube holders 41 to 43 with respect to the connection holder 5 may be four types or more or two types instead of three types.

  In the above embodiment, the connection holder 5 is fixed to the vehicle body by tightening the bolt 16 via the bracket 10. However, for example, the bracket 10 is excluded and a plate-like shape that changes to the bracket insertion fixing portion 11 of the connection holder 5 is removed. It is also possible to fasten and fix the fixing portion (not shown) to the vehicle body directly with a bolt. Moreover, it is also possible to use a synthetic resin locking clip or the like instead of the bolt 16.

  Moreover, in the said embodiment, although the edge part of the tube holders 41-43 was arrange | positioned in the radial direction outer side of the edge part of the division | segmentation holder 5, contrary to this, the tube holder is arranged in the radial direction inner side of the edge part of the division | segmentation holder 5. It is also possible to arrange the ends of 41 to 43. However, the former is preferable in terms of assembly workability and cable insertion workability. The configuration described in the above embodiment is also effective as a method for forming the vehicle cable exterior members 1, 1 ′ in addition to the vehicle cable exterior members 1, 1 ′.

  The vehicle cable exterior member according to the present invention is used to enhance the transportability during transportation and the like, to easily obtain the exterior shape along the cable routing route set for each vehicle type, and to reduce the cost. Can do.
