[Figure 6] This is a perspective view of the retaining member of the retaining member assembly structure according to this embodiment. [Figure 7] This is a cross-sectional view of the retaining member of the retaining member assembly structure according to this embodiment. [Modes for carrying out the invention]

[0009] The retaining member assembly structure according to this embodiment will be described in detail below with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0010] As shown in Figure 1, the retaining member assembly structure 1 according to this embodiment is applied, for example, to the assembly of a retaining member 7 to an arrangement member 5, such as a panel placed on a vehicle, which holds an electric wire 3 placed on the arrangement member 5.

[0011] As shown in Figures 1 to 7, the retaining member assembly structure 1 comprises an electric wire 3, an arrangement member 5, and a retaining member 7.

[0012] As shown in Figures 1 to 4, the electric wire 3 consists of a coated electric wire in which the outer circumference of a conductor made of a conductive material is covered with an insulating coating made of an insulating material. The electric wire 3 electrically connects two electrical components (not shown), for example, between a power source and equipment mounted on a vehicle, or between equipment and equipment.

[0013] As shown in Figures 1 to 5, the arrangement member 5 is a panel arranged to partition the interior of a vehicle, for example. Electric wires 3 are arranged on one side of the arrangement member 5. The arrangement member 5 is provided with a plurality (two in this case) of boss portions 9 that protrude toward the electric wires 3 (holding member 7). The boss portions 9 consist of plate-shaped members 11 that extend in a plane direction perpendicular to the plane of the arrangement member 5, which is a plane direction parallel to the longitudinal and radial directions of the hole portion 17 of the holding member 7. By forming the boss portions 9 with plate-shaped members 11, they can be made more elastically deformable compared to when the boss portions 9 are formed in a solid columnar shape. The boss portions 9 are formed in an X shape, with a plurality (two in this case) of plate-shaped members 11 intersecting each other so that their midpoints in the width direction intersect. By providing boss portions 9 on the arrangement member 5, there is no need to provide holes in the arrangement member 5 for fixing the electric wires 3 (holding member 7). Therefore, it is possible to prevent water and other substances from entering through the holes in the arrangement member 5. In addition, there is no need to place sealing members or the like in the holes of the placement member 5, which reduces the number of parts.

[0014] As shown in Figures 1-4, 6, and 7, the retaining member 7 is made of an insulating material such as synthetic resin. Multiple retaining members 7 (two in this case) are used. The retaining member 7 comprises a main body portion 13, a wire holding portion 15, and a hole portion 17.

[0015] The main body portion 13 is formed in the shape of a rectangular plate. The length of the main body portion 13 is set to be longer than the diameter of the electric wire 3. An electric wire holding portion 15 is provided on one side of the main body portion 13 in the longitudinal direction, and a hole portion 17 is provided on the other side of the main body portion 13 in the longitudinal direction.

[0016] The wire holding portion 15 has a band portion 19 and a locking portion 21. The band portion 19 is formed from a single member with one end continuous with the main body portion 13. The length of the band portion 19 is set to be longer than the circumferential length of the wire 3 so that it can be wrapped around the outer circumference of the wire 3. The locking portion 21 is provided inside the main body portion 13 and consists of a hole into which the other end of the band portion 19 can be inserted and locked. The locking portion 21 locks the other end of the band portion 19 that is wrapped around the outer circumference of the wire 3, and maintains the state in which the band portion 19 is wrapped around the outer circumference of the wire 3. By holding the wire 3 with the wire holding portion 15, the assembled state of the holding member 7 with respect to the wire 3 can be maintained.

[0017] The hole 17 is formed as a circular through-hole that penetrates the main body 13 in the thickness direction. The inner diameter of the hole 17 is set to be slightly larger than the width of the plate-shaped member 11 of the boss portion 9. The boss portion 9 of the placement member 5 is inserted into the hole 17 when the holding member 7 is assembled to the placement member 5. When the boss portion 9 is inserted into the hole 17, the tip side of the boss portion 9 is exposed from the hole 17. An engagement portion 23 is provided on the tip side of the boss portion 9 that is exposed from the hole 17.

[0018] As shown in FIGS. 1 to 5, the engaging portion 23 protrudes from the side surface in the width direction of the plate-like member 11 toward the outside in the width direction of the plate-like member 11 on the tip side of the plate-like member 11 constituting the boss portion 9. The protruding height of the engaging portion 23 is set to be higher than the diameter of the hole portion 17. The engaging portion 23 is provided on both sides in the width direction of each of the plurality (here, two) of plate-like members 11, and a plurality (here, four) of engaging portions 23 are provided on the boss portion 9. The engaging portion 23 is arranged such that the surface on the hole portion 17 side can be engaged with the edge portion located around the opening of the hole portion 17 in a state where the boss portion 9 passes through the hole portion 17. By engaging the engaging portion 23 with the edge portion of the hole portion 17, the boss portion 9 can be prevented from coming out of the hole portion 17, and the holding member 7 can be fixed to the arranging member 5. Since the engaging portion 23 is provided on the plate-like member 11, when the boss portion 9 is inserted into the hole portion 17, it can be inserted into the hole portion 17 due to the elastic deformation of the plate-like member 11. The engaging portion 23 inserted into the hole portion 17 is arranged to be able to engage with the edge portion of the hole portion 17 by the restoration of the plate-like member 11 after the boss portion 9 is inserted into the hole portion 17. Therefore, after the boss portion 9 is inserted into the hole portion 17, the holding member 7 can be fixed to the arranging member 5 without performing operations such as deforming the boss portion 9, and the assembling property can be improved. Since the engaging portion 23 is provided on each of the plurality of plate-like members 11, there can be many engaging portions with the edge portion of the hole portion 17, and the fixing of the holding member 7 can be stabilized.

[0019] A tapered surface 25 is formed on the outer surface on the front side in the insertion direction of the boss portion 9 with respect to the hole portion 17 of the engaging portion 23. The tapered surface 25 is inclined so as to widen from the front side in the insertion direction of the boss portion 9 with respect to the hole portion 17 toward the rear side in the insertion direction. When the boss portion 9 is inserted into the hole portion 17, the tapered surface 25 slides on the opening edge of the hole portion 17, making it easier to insert the boss portion 9 into the hole portion 17. When the tapered surface 25 slides on the opening edge of the hole portion 17, the plate-like member 11 is elastically deformed, making it possible to insert the engaging portion 23 into the hole portion 17. Therefore, by providing the tapered surface 25 on the outer surface of the engaging portion 23, it is possible to make it easier to insert the boss portion 9 having the engaging portion 23 into the hole portion 17, and the assembling property can be improved.

[0020] In addition, the hole portion 17 is disposed at a position visible from the electric wire 3 when viewed from the assembling direction of the holding member 7 with respect to the arranging member 5 in a state where the electric wire 3 is held by the electric wire holding portion 15 on the other side in the length direction of the main body portion 13. For this reason, when the holding member 7 is assembled to the arranging member 5, the insertion of the hole portion 17 into the boss portion 9 can be visually recognized, and the assembling property can be further improved.

[0021] As an example of the assembling method in such a holding member assembling structure 1, first, the band portion 19 is wound around the outer periphery of the electric wire 3, and the holding member 7 is assembled to the electric wire 3 through the electric wire holding portion 15. Then, the hole portion 17 of the holding member 7 is inserted into the boss portion 9 of the arranging member 5, the engaging portion 23 of the boss portion 9 is engaged with the edge portion of the hole portion 17, the holding member 7 is fixed to the arranging member 5, the electric wire 3 is arranged on the arranging member 5 through the holding member 7, and the assembling is completed.

[0022] In such a holding member assembling structure 1, an arranging member 5 on which the electric wire 3 is arranged and a holding member 7 that holds the electric wire 3 and is assembled to the arranging member 5 are provided. Further, the arranging member 5 is provided with a boss portion 9 that protrudes toward the holding member 7. Further, the holding member 7 is provided with a hole portion 17 into which the boss portion 9 is inserted. Further, the boss portion 9 is composed of a plate-like member 11 that extends in a plane direction parallel to the length direction and the radial direction of the hole portion 17. And the plate-like member 11 is provided with an engaging portion 23 that is engaged with the edge portion of the hole portion 17.

[0023] By forming the boss portion 9 with a plate-shaped member 11, it can be made more elastically deformable compared to when the boss portion 9 is formed as a solid columnar shape. Since the engaging portion 23 is provided on the plate-shaped member 11, when the boss portion 9 is inserted into the hole portion 17, it can be inserted into the hole portion 17 by the elastic deformation of the plate-shaped member 11. After the boss portion 9 is inserted into the hole portion 17, the engaging portion 23 is positioned to engage with the edge of the hole portion 17 by the return of the plate-shaped member 11. The engagement between the engaging portion 23 and the edge of the hole portion 17 prevents the boss portion 9 from coming out of the hole portion 17, and the retaining member 7 can be fixed to the placement member 5. For this reason, after inserting the boss portion 9 into the hole portion 17, the retaining member 7 can be fixed to the placement member 5 without any work such as deforming the boss portion 9, thereby improving ease of assembly.

[0024] Therefore, this type of retaining member assembly structure 1 can improve ease of assembly.

[0025] Furthermore, the outer surface of the engaging portion 23 has a tapered surface 25 that is inclined to widen from the front side in the insertion direction of the boss portion 9 into the hole 17 to the rear side in the insertion direction.

[0026] The tapered surface 25 slides against the opening edge of the hole 17 when the boss portion 9 is inserted into the hole 17, making it easier to insert the boss portion 9 into the hole 17. When the tapered surface 25 slides against the opening edge of the hole 17, it elastically deforms the plate-shaped member 11, allowing the engaging portion 23 to be inserted into the hole 17. Therefore, by providing the tapered surface 25 on the outer surface of the engaging portion 23, it is possible to make it easier to insert the boss portion 9 having the engaging portion 23 into the hole 17, thereby improving ease of assembly.

[0027] Furthermore, the boss portion 9 is formed by the intersection of multiple plate-like members 11. The engaging portion 23 is provided on each of the multiple plate-like members 11.

[0028] Therefore, the hole 17 can have many points of engagement with its edge, which stabilizes the fixing of the retaining member 7.

[0029] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment.

[0030] For example, although two bosses are provided on the mounting member, the arrangement is not limited to this; one boss or three or more bosses may be provided on the mounting member.

[0031] Furthermore, while the mounting member is shown as a panel, it is not limited to this; the mounting member may also be a casing, and any type of mounting member is acceptable as long as it is a member on which electric wires are placed.

[0032] Furthermore, although the boss portion is composed of two plate-like members, it is not limited to this, and the boss portion may be composed of three or more plate-like members. [Explanation of Symbols]
