[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 portion 9 consists of elastically deformable elastic pieces 11 that are radially inward of the hole 17 of the holding member 7, with the arrangement member 5 side as the base end and the protruding end side as the free end. The boss portion 9 is formed of a plurality (four in this case) of elastic pieces 11 such that there is a linear space between adjacent elastic pieces 11, 11. In this case, the space formed between the plurality of elastic pieces 11, 11 is formed in an X shape. By providing boss portions 9 on the arrangement member 5, it is not necessary 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, it is not necessary to place sealing members or the like in the holes of the arrangement member 5, and the number of parts can be reduced.

[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 diameter of the boss portion 9 (the diameter of the circumscribed circle that is circumscribed by the multiple elastic pieces 11). 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. Inside the hole 17, a partition wall 23 is provided that divides the inside of the hole 17 into two spaces. The partition wall 23 is positioned between adjacent elastic pieces 11, 11 when the boss portion 9 is inserted into the hole 17. By positioning the partition wall 23 between adjacent elastic pieces 11, 11, the holding member 7 does not rotate relative to the placement member 5 when the boss portion 9 is inserted into the hole 17, thereby improving ease of assembly. In addition, the rotation of the holding member 7 when it is assembled to the placement member 5 can be restricted, and the fixing of the holding member 7 can be stabilized. When the boss portion 9 is inserted into the hole 17, the tip of the boss portion 9 is exposed from the hole 17. An engaging portion 25 is provided on the tip of the boss portion 9 that is exposed from the hole 17.

[0018] As shown in FIGS. 1 to 5, the engaging portion 25 protrudes outward from the side surface of the elastic piece 11 on the free end side of the elastic piece 11 constituting the boss portion 9. The protruding height of the engaging portion 25 is set to be higher than the diameter of the hole portion 17. The engaging portion 25 is provided on each of a plurality (here, four) of elastic pieces 11, and a plurality (here, four) of engaging portions 25 are provided on the boss portion 9. The engaging portion 25 is arranged such that in a state where the boss portion 9 passes through the hole portion 17, the surface on the hole portion 17 side can engage with an edge portion located around the opening of the hole portion 17. By engaging the engaging portion 25 with the edge portion of the hole portion 17, the boss portion 9 is 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 25 is provided on the elastic piece 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 elastic piece 11. The engaging portion 25 inserted into the hole portion 17 is arranged to be able to engage with the edge portion of the hole portion 17 due to the restoration of the elastic piece 11 after the boss portion 9 is inserted into the hole portion 17. For this reason, after inserting the boss portion 9 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.

[0019] A tapered surface 27 is formed on the outer surface of the engaging portion 25 on the front side in the insertion direction of the boss portion 9 with respect to the hole portion 17. The tapered surface 27 is inclined so as to expand 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 27 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 27 slides on the opening edge of the hole portion 17, the elastic piece 11 is elastically deformed, making it possible to insert the engaging portion 25 into the hole portion 17. For this reason, by providing the tapered surface 27 on the outer surface of the engaging portion 25, it is possible to make it easier to insert the boss portion 9 having the engaging portion 25 into the hole portion 17, and the assembling property can be improved.

[0020] 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 while the electric wire 3 is held by the electric wire holding portion 15 on the other side in the longitudinal direction of the main body portion 13. Therefore, when the holding member 7 is assembled to the arranging member 5, insertion of the hole portion 17 into the boss portion 9 can be visually confirmed, 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 25 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, and the electric wire 3 is arranged on the arranging member 5 through the holding member 7 to complete the assembling.

[0022] In such a holding member assembling structure 1, it includes 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. 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. The boss portion 9 is composed of a plurality of elastic pieces 11 that can be elastically deformed toward the inner side in the radial direction of the hole portion 17. And the elastic piece 11 is provided with an engaging portion 25 that is engaged with the edge portion of the hole portion 17.

[0023] Since the engaging portion 25 is provided on the elastic piece 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 elastic piece 11. The engaging portion 25 inserted into the hole portion 17 is arranged to be engaged with the edge portion of the hole portion 17 by the restoration of the elastic piece 11 after the boss portion 9 is inserted into the hole portion 17. By the engagement between the engaging portion 25 and the edge portion of the hole portion 17, the boss portion 9 is prevented from coming out of the hole portion 17, and the holding member 7 can be fixed to the arranging member 5. 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 operations such as deforming the boss portion 9, and the assembling property can be improved.

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

[0025] Furthermore, the hole 17 is provided with a partition wall 23 positioned between adjacent elastic pieces 11, 11.

[0026] By arranging a partition wall 23 between adjacent elastic pieces 11, 11, the retaining member 7 does not rotate relative to the placement member 5 when the boss portion 9 is inserted into the hole portion 17, thereby improving ease of assembly. In addition, the rotation of the retaining member 7 when it is assembled to the placement member 5 can be restricted, and the fixing of the retaining member 7 can be stabilized.

[0027] Furthermore, the outer surface of the engaging portion 25 has a tapered surface 27 that is inclined to widen from the front side to the rear side in the insertion direction of the boss portion 9 relative to the hole 17.

[0028] The tapered surface 27 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 27 slides against the opening edge of the hole 17, it elastically deforms the elastic piece 11, allowing the engaging portion 25 to be inserted into the hole 17. Therefore, by providing the tapered surface 27 on the outer surface of the engaging portion 25, it is possible to make it easier to insert the boss portion 9 having the engaging portion 25 into the hole 17, thereby improving assembly efficiency.

[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 four elastic pieces, it is not limited to this, and the boss portion may be composed of three or fewer elastic pieces, or five or more elastic pieces.

[0033] Furthermore, while the partition wall divides the inside of the hole into two spaces, it is not limited to this. For example, the partition wall may be provided projecting inward at one location in the circumferential direction inside the hole, and the partition wall may be placed between two adjacent elastic pieces at one location. The arrangement of the partition wall can be any arrangement. [Explanation of Symbols]
