[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 that is 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 multiple (two in this case) cylindrical boss portions 9 that protrude toward the electric wires 3 (holding members 7). 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 members 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, 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 are used (two in this case). The retaining member 7 comprises a main body 11, a wire holding portion 13, and a hole portion 15.

[0015] The main body 11 is formed in the shape of a rectangular plate. The length of the main body 11 is set to be longer than the diameter of the electric wire 3. An electric wire holding portion 13 is provided on one side of the main body 11 in the longitudinal direction, and a hole portion 15 is provided on the other side of the main body 11 in the longitudinal direction.

[0016] The wire holding portion 13 has a band portion 17 and a locking portion 19. The band portion 17 is formed from a single member with one end continuous with the main body portion 11. The length of the band portion 17 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 19 is provided inside the main body portion 11 and consists of a hole into which the other end of the band portion 17 can be inserted and locked. The locking portion 19 locks the other end of the band portion 17 that is wrapped around the outer circumference of the wire 3, and maintains the state in which the band portion 17 is wrapped around the outer circumference of the wire 3. By holding the wire 3 with the wire holding portion 13, the assembled state of the holding member 7 with respect to the wire 3 can be maintained.

[0017] The hole 15 is formed as a circular through-hole that penetrates the main body 11 in the thickness direction. The inner diameter of the hole 15 is set to be slightly larger than the outer diameter of the boss portion 9. When the holding member 7 is assembled to the placement member 5, the boss portion 9 of the placement member 5 is inserted into the hole 15. When the boss portion 9 is inserted into the hole 15, the tip side of the boss portion 9 is exposed from the hole 15. An engagement portion 21 is provided on the tip side of the boss portion 9 that is exposed from the hole 15.

[0018] As shown in FIGS. 1 to 5, the engaging portion 21 is formed in a circular flange shape that protrudes outward from the outer peripheral surface of the boss portion 9 toward the tip side of the boss portion 9 and is continuous in the circumferential direction of the boss portion 9. The diameter of the engaging portion 21 is set larger than the diameter of the hole portion 15. In a state where the boss portion 9 passes through the hole portion 15, the surface on the hole portion 15 side of the engaging portion 21 is arranged to be engageable with an edge portion located around the opening of the hole portion 15. By engaging the engaging portion 21 with the edge portion of the hole portion 15, the boss portion 9 is prevented from coming out of the hole portion 15, and the holding member 7 can be fixed to the arranging member 5. Since the engaging portion 21 is formed continuously in the circumferential direction of the boss portion 9, it is possible to have a wide engaging area with the edge portion of the hole portion 15, and the fixing of the holding member 7 can be stabilized.

[0019] A tapered surface 23 is formed on the outer surface of the engaging portion 21 on the front side in the insertion direction of the boss portion 9 with respect to the hole portion 15. The tapered surface 23 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 15 toward the rear side in the insertion direction. The tapered surface 23 is formed continuously at the peripheral edge of the engaging portion 21. For this reason, the outer surface of the engaging portion 21 is inclined by the tapered surface 23 so as to reduce the diameter toward the tip side of the boss portion 9. When the boss portion 9 is inserted into the hole portion 15, the tapered surface 23 slides on the opening edge of the hole portion 15, making it easier to insert the boss portion 9 into the hole portion 15. When the tapered surface 23 slides on the opening edge of the hole portion 15, the engaging portion 21 is elastically deformed so as to reduce the diameter toward the radially inner side, making it possible to insert the engaging portion 21 into the hole portion 15. When the engaging portion 21 inserted into the hole portion 15 is exposed from the hole portion 15, it is restored and arranged to be engageable with the edge portion of the hole portion 15. By providing the tapered surface 23 on the outer surface of the engaging portion 21, even if the engaging portion 21 that is engaged with the edge portion of the hole portion 15 is provided on the boss portion 9, the boss portion 9 can be inserted into the hole portion 15. For this reason, after inserting the boss portion 9 into the hole portion 15, 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. In addition, by forming the tapered surface 23 continuously at the peripheral edge of the engaging portion 21, the engaging portion 21 can be stably inserted into the hole portion 15.

[0020] Note that the hole portion 15 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 13 on the other side in the length direction of the main body portion 11. Therefore, when assembling the holding member 7 to the arranging member 5, insertion of the hole portion 15 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 17 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 13. Then, the hole portion 15 of the holding member 7 is inserted into the boss portion 9 of the arranging member 5, the engaging portion 21 of the boss portion 9 is engaged with the edge portion of the hole portion 15, 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, 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 15 into which the boss portion 9 is inserted. Further, the boss portion 9 is provided with an engaging portion 21 that is engaged with the edge portion of the hole portion 15. And, on the outer surface of the engaging portion 21, a tapered surface 23 is formed that is inclined so as to spread from the front side in the insertion direction of the boss portion 9 into the hole portion 15 toward the rear side in the insertion direction.

[0023] By providing the engaging portion 21 that is engaged with the edge portion of the hole portion 15 on the boss portion 9, the boss portion 9 can be prevented from coming out of the hole portion 15, and the holding member 7 can be fixed to the arranging member 5. By providing the tapered surface 23 on the outer surface of the engaging portion 21, even if the engaging portion 21 that is engaged with the edge portion of the hole portion 15 is provided on the boss portion 9, the boss portion 9 can be inserted into the hole portion 15. Therefore, after inserting the boss portion 9 into the hole portion 15, 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.

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

[0025] Furthermore, the engaging portion 21 is formed continuously in the circumferential direction of the boss portion 9. The tapered surface 23 is formed continuously on the periphery of the engaging portion 21.

[0026] By forming the engaging portion 21 continuously in the circumferential direction of the boss portion 9, the engagement area with the edge of the hole portion 15 can be increased, and the fixing of the retaining member 7 can be stabilized. In addition, by forming the tapered surface 23 continuously on the periphery of the engaging portion 21, the engaging portion 21 can be stably inserted into the hole portion 15.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Furthermore, while the engaging portion is formed continuously in the circumferential direction of the boss portion, it is not limited to this, and multiple engaging portions may be formed discontinuously in the circumferential direction of the boss portion, with a tapered surface provided on the outer surface of each engaging portion.
