[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wire holding member of the present disclosure is as follows.

[0011] (1) A wire holding member comprising: a bottom; a first wall protruding from the bottom; a second wall protruding from the bottom and extending parallel to the first wall at a distance; a first protrusion protruding from the first wall toward the second wall; and a second protrusion protruding from the second wall toward the first wall, wherein the first protrusion and the second protrusion are positioned apart from each other in the extension direction of the first wall, at least one of the first protrusion and the second protrusion protrudes at a position apart from the bottom, and when viewed along the extension direction of the first wall, a tip of the first protrusion and a tip of the second protrusion overlap.

[0012] According to this electric wire holding member, the first protrusion and the second protrusion are positioned apart from each other in the extending direction of the first wall. Therefore, an electric wire can be passed between the first protrusion and the second protrusion at an angle relative to the first wall. Furthermore, when an electric wire that passes between the first protrusion and the second protrusion toward the bottom is brought closer to the first wall in a parallel position, the electric wire is disposed between the bottom and the first or second protrusion that protrudes away from the bottom. Therefore, deformation of the structural portion that holds the electric wire can be suppressed when holding the electric wire. Furthermore, when viewed along the extending direction of the first wall, the tip of the first protrusion and the tip of the second protrusion overlap. Therefore, an electric wire that is brought closer to the first wall in a parallel position has difficulty passing between the first protrusion and the second protrusion. Therefore, the electric wire is securely held.

[0013] (2) In the electric wire holding member of (1), the first protrusion may be a rib extending from the bottom toward the tip of the first wall, and the second protrusion may be a retaining piece protruding at a position away from the bottom.

[0014] This allows the first wall to be reinforced by the rib extending from the bottom toward the tip of the first wall. A space for accommodating electric wires can be secured between the bottom and the retaining piece that protrudes at a position away from the bottom.

[0015] (3) In the electric wire holding member of (2), the length of the rib projecting from the first wall may be smaller than the length of the pressing piece projecting from the second wall.

[0016] This makes it easier to increase the space for accommodating the electric wires between the bottom and the retaining piece.

[0017] (4) In the electric wire holding member of (2) or (3), the rib may include a first rib and a second rib, and the retaining piece may be located between the first rib and the second rib in the extension direction of the first wall.

[0018] In this case, when the electric wire is brought close to a straight line between the first wall and the second wall, the first rib and the second rib keep the electric wire positioned in front of the tip of the pressing piece, thereby more reliably holding the electric wire.

[0019] (5) In the electric wire holding member of (4), the pressing piece may include a tapered tip portion that gradually becomes thinner toward the tip side.

[0020] This makes it easy to ensure sufficient space for passing the electric wire between the tapered tip of the pressing piece and the first rib, and between the tapered tip and the second rib, thereby facilitating the work of holding the electric wire.

[0021] (6) In any one of the electric wire holding members (2) to (5), the second wall and the retaining piece may be located on the inside, and the first wall and the rib may be located on the outside, in a bending path that holds the electric wire in a bent state.

[0022] In this case, the wires tend to pass near the inner side of the bending path, making it easier to shorten the length of the wires.

[0023] (7) The electric wire holding member may be any one of (1) to (6), and may include a first electric wire positioning portion and a second electric wire positioning portion that position the electric wire at a fixed position, and the first protrusion and the second protrusion may be located between the first electric wire positioning portion and the second electric wire positioning portion along the path of the electric wire.

[0024] In this case, by positioning the electric wire with the first electric wire positioning part and the second electric wire positioning part, it is easy to keep the electric wire taut between the first electric wire positioning part and the second electric wire positioning part, which makes it difficult for the electric wire to pass between the first protrusion and the second protrusion, and the electric wire is firmly held in place.

[0025] (8) The electric wire holding member according to any one of (1) to (7) may be made of fiber reinforced resin.

[0026] In this way, when the electric wire holding member is formed from a fiber reinforced resin, it is difficult to impart elasticity to the protrusions for holding the electric wires. In such a case, the electric wires can be held while suppressing deformation of the protrusions.

[0027] [Details of the embodiments of the present disclosure] Specific examples of the electric wire holding member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0028] [Embodiment] Hereinafter, an electric wire holding member according to an embodiment will be described.

[0029] <Overall structure> Fig. 1 is a perspective view showing the electric wire holding member 20. Fig. 2 is a plan view showing the electric wire holding member 20. The electric wire holding member 20 is a member that holds the electric wire 10 so that it does not come off the electric wire holding member 20. The electric wire holding member 20 may be a member that holds the electric wire 10 along a fixed path. The electric wire 10 is a member that has a core wire and a covering around the core wire.

[0030] In this embodiment, a terminal 18 is connected to the electrical component 16, and the electrical wire 10 extends from the terminal 18. The electrical wire holding member 20 holds the electrical wire 10 along a fixed path around the electrical component 16. The electrical component 16 may be, for example, a battery.

[0031] In this embodiment, the electric wire holding member 20 is assembled around a plurality of (two are illustrated in FIGS. 1 and 2) electric components 16. The electric wire holding member 20 may have a role of holding the plurality of electric components 16 together.

[0032] More specifically, the wire holding member 20 is assembled around the top of a plurality of electrical components 16. A terminal 18 is connected to each of the plurality of electrical components 16, and an electrical wire 10 extends from each of the plurality of terminals 18. The wire holding member 20 holds the electrical wires 10 along a fixed path around the plurality of electrical components 16. The wire holding member 20 may hold the plurality of electrical wires 10 along a path that brings the plurality of electrical wires 10 together in at least one location. Conversely, the wire holding member 20 may hold a bundle of electrical wires along a fixed path that branches them out toward each electrical component 16.

[0033] For example, the wire holding member 20 has a base portion 22, a first surrounding wall portion 30, a second surrounding wall portion 40, a first outer wall portion 50, a second outer wall portion 60, and a third outer wall portion 70. The first surrounding wall portion 30, the second surrounding wall portion 40, the first outer wall portion 50, the second outer wall portion 60, and the third outer wall portion 70 are plate-shaped portions that protrude toward one main surface of the base portion 22. The space on one main surface of the base portion 22 is partitioned by the first surrounding wall portion 30, the second surrounding wall portion 40, the first outer wall portion 50, the second outer wall portion 60, and the third outer wall portion 70, thereby forming a space on one main surface of the base portion 22 that holds the wires 10 along a certain path.

[0034] The electric wire holding member 20 may be a part that is integrally molded from resin using a mold. The electric wire holding member 20 may be formed from fiber reinforced resin. Fiber reinforced resin is a resin that has been strengthened by compounding fiber F with resin (see FIG. 4). The fiber may be glass fiber, carbon fiber, or resin fiber.

[0035] The base portion 22 is a flat portion and is formed with openings, here multiple (two in FIGS. 1 and 2) rectangular openings 22h, in which the upper portions of the electrical components 16 can be placed. The electrical components 16 can be exposed from the upper side of the base portion 22 via the openings 22h.

[0036] One of the plurality of openings 22h is surrounded by a first surrounding wall portion 30, and another of the plurality of openings 22h is surrounded by a second surrounding wall portion 40. The first surrounding wall portion 30 and the second surrounding wall portion 40 have a rectangular frame-like wall shape. The first surrounding wall portion 30 and the second surrounding wall portion 40 are adjacent to each other with a gap between them. A long and narrow space is formed between the first surrounding wall portion 30 and the second surrounding wall portion 40 in which the electric wire 10 can be arranged.

[0037] Terminal set portions 32, 42 into which the terminals 18 can be set are formed at partial outer peripheral positions in the circumferential direction of each of the first surrounding wall portion 30 and the second surrounding wall portion 40. For example, the end of the terminal 18 to which the electric wire 10 is connected is fitted into the terminal set portion 32, 42 and set. In this state, the end of the terminal 18 opposite to the electric wire 10 protrudes into the opening 22h and is connected to an electrode of the electric component 16 by soldering or the like. By setting the terminal 18 in the terminal set portion 32, 42, the electric wire 10 connected and fixed to the terminal 18 by crimping or the like is also positioned at a fixed position in the wire holding member 20.

[0038] The first outer wall portion 50 is located at a distance from the first surrounding wall portion 30 and the second surrounding wall portion 40 on the side where the terminal set portions 32, 42 are located. Between the first outer wall portion 50 and the first surrounding wall portion 30 and between the first outer wall portion 50 and the second surrounding wall portion 40, respectively, a long and narrow space in which the electric wire 10 can be arranged is formed.

[0039] The second outer wall portion 60 is located on the opposite side to the first outer wall portion 50 and spaced apart from the first surrounding wall portion 30 and the second surrounding wall portion 40. A long and narrow space is formed between the second outer wall portion 60 and the second surrounding wall portion 40 in which the electric wire 10 can be arranged.

[0040] The third outer wall portion 70 is located at a distance from the second surrounding wall portion 40 on the opposite side to the first surrounding wall portion 30. A long and narrow space is formed between the third outer wall portion 70 and the second surrounding wall portion 40 in which the electric wire 10 can be arranged.

[0041] Terminals 18 connected to electrical components 16 exposed inside the first surrounding wall portion 30 are held by a terminal set portion 32 between the first surrounding wall portion 30 and the first outer wall portion 50. The electric wires 10 extending from the terminals 18 are guided to pass through a path PZ1 between the first surrounding wall portion 30 and the first outer wall portion 50, a path PZ2 between the first surrounding wall portion 30 and the second surrounding wall portion 40, and a path PZ3 between the second surrounding wall portion 40 and the second outer wall portion 60. The electric wires 10 may be guided toward a lead-out portion 28 on the outer periphery of the second surrounding wall portion 40 that is farthest from the first outer wall portion 50 and the first surrounding wall portion 30.

[0042] The path PZ1 is connected to one end of the path PZ2, and the path PZ3 is connected to the other end of the path PZ2. The paths PZ1 and PZ3 extend on opposite sides of the path PZ2. In this embodiment, the angles of the paths PZ1 and PZ3 with respect to the path PZ2 are 90°, but the angles can be any.

[0043] Terminals 18 connected to electrical components 16 exposed inside the second surrounding wall portion 40 are held by the terminal set portion 32 between the second surrounding wall portion 40 and the first outer wall portion 50. The electric wires 10 extending from the terminals 18 are guided to pass through a path PL1 between the second surrounding wall portion 40 and the first outer wall portion 50 and a path PL2 between the second surrounding wall portion 40 and the third outer wall portion 70. The electric wires 10 may be guided toward the lead-out portion 28, similar to the electric wires 10 above.

[0044] The path PL2 is connected to one end of the path PL1. In this embodiment, the angle of the path PZ2 with respect to the path PL1 is 90°, but this angle is arbitrary.

[0045] Path PL1 extends as an extension of path PZ1. Paths PZ2 and PL2 are parallel to each other with the second surrounding wall portion 40 in between. Path PZ3 is parallel to paths PZ1 and PL1. Path PZ3 extends parallel to path PL1 with the second surrounding wall portion 40 in between.

[0046] In each of the paths PZ1, PZ2, PZ3, PL1, and PL2, the base portion 22 forms the bottom of the space that accommodates the electric wire 10. In each of the paths PZ1, PZ2, PZ3, PL1, and PL2, an opening is formed on the side opposite to the bottom, and the electric wire 10 is pushed from the opening side toward each of the paths PZ1, PZ2, PZ3, PL1, and PL2.

[0047] The plurality of electric wires 10 are drawn out to the drawn-out portion 28. In the drawn-out portion 28, the electric wires 10 may be bound and fixed to the base portion 22. For example, a hole 28h is formed in the drawn-out portion 28. A binding member 29 is passed through the hole 28h, and bound and fixed to the electric wires 10 on the drawn-out portion 28 and between the hole 28h and an edge portion of the drawn-out portion 28. In this way, the electric wires 10 are positioned at a fixed position relative to the drawn-out portion 28.

[0048] The electric wires 10 held in the paths PZ1, PZ2, and PZ3 and the electric wires 10 held in the paths PL1 and PL2 are held so as not to come off in a direction away from the base portion 22, respectively.

[0049] In this embodiment, each of the paths PZ2, PZ3, and PL2 has a configuration for holding the electric wire 10. Focusing on the path PZ3, an example of the configuration of the electric wire holding portion will be described more specifically.

[0050] <Configuration of the wire holding part> Fig. 3 is a partially enlarged perspective view of the path PZ3, Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3, and Fig. 5 is a partially enlarged plan view of the path PZ3.

[0051] In the path PZ3, it can be understood that a part of the base portion 22 is the bottom 90, a part of the second outer wall portion 60 is the first wall 92, and a part of the second surrounding wall portion 40 is the second wall 94.

[0052] In this case, the first wall 92 protrudes from the bottom 90, and the second wall 94 also protrudes from the bottom 90. The second wall 94 extends parallel to the first wall 92 with a gap therebetween.

[0053] The electric wire 10 is housed in a space S surrounded by the bottom 90, the first wall 92, and the second wall 94. To prevent the electric wire 10 from coming off the space S, the following configuration is employed.

[0054] That is, the rib 100 protrudes as a first protrusion from the first wall 92 toward the second wall 94. The rib 100 is formed in an elongated shape extending from the bottom 90 toward the tip of the first wall 92 in the protruding direction. It is preferable that the surface of the rib 100 opposite the bottom be located farther from the bottom than the surface of the pressing piece 110 facing the bottom 90. The surface of the rib 100 opposite the bottom may be parallel to the bottom 90.

[0055] In this embodiment, the rib 100 is formed in the shape of a long, narrow plate that is perpendicular to both the first wall 92 and the bottom 90. The rib 100 is continuous with both the first wall 92 and the bottom 90. When viewed in a plan view along the direction in which the first wall 92 protrudes relative to the bottom 90, both corners on the tip side of the rib 100 are rounded. When viewed along the direction in which the first wall 92 extends, the corners of the rib 100 that are farther from the bottom 90 and the first wall 92 are rounded.

[0056] Furthermore, a pressing piece 110 protrudes as a second protrusion from the second wall 94 toward the first wall 92. The pressing piece 110 is formed in an elongated shape protruding from the bottom 90 at a position away from the tip of the second wall 94 in the protruding direction. The position of the pressing piece 110 may be just before the tip edge of the second wall 94 in the protruding direction, or may be at that tip edge. A gap is formed between the pressing piece 110 and the bottom 90 in which an electric wire 10 can be arranged, preferably a gap in which multiple electric wires can be arranged.

[0057] The shape of the holding piece 110 is arbitrary, and may be a long, thin plate, a round bar, or a square bar. In this embodiment, the holding piece 110 is a long, thin plate that is flat along the direction of the bottom 90.

[0058] The tip of the pressing piece 110 is formed into a tapered tip 112 that gradually becomes thinner toward the tip side when viewed from above. More specifically, the tapered tip 112 has a shape in which the corners on the tip side of an isosceles triangular plate portion are rounded. The tapered tip may be formed into a semicircular plate shape when viewed from above.

[0059] When viewed along the extending direction of the second wall 94, the corners on the tip side of the pressing piece 110 may be rounded.

[0060] The rib 100 and the holding piece 110 are positioned apart from each other in the extension direction of the first wall 92. The extension direction of the first wall 92 is the extension direction of the path PZ3 and also the extension direction of the second wall 94. When viewed in a plan view along the protruding direction of the first wall 92 and the second wall 94 relative to the bottom 90, a gap exists between the rib 100 and the holding piece 110. The gap is located between the tapered tip 112 of the holding piece 110 and the tip of the rib 100. It is preferable that the minimum width d of the gap is equal to or greater than the diameter φ of the electric wire 10 to be held. The electric wire 10 can pass through the gap.

[0061] When viewed along the extension direction of the first wall 92, the tip of the rib 100 and the tip of the retaining piece 110 overlap. The overlapping point is located between the first wall 92 and the second wall 94 and away from the bottom 90. When viewed along the extension direction of the first wall 92, the electric wire 10 can be placed in a space surrounded by the upper surface of the bottom 90, the inner surface of the retaining piece 110, the tip of the rib 100, and the inner surface of the second wall 94.

[0062] The protruding length L1 of the rib 100 relative to the first wall 92 may be smaller than the protruding length L2 of the retaining piece 110 relative to the second wall 94. This increases the space between the tip edge of the rib 100 and the inner surface of the second wall 94 between the first wall 92 and the second wall 94, thereby increasing the space for accommodating the electric wire 10. This is particularly advantageous when the distance between the first wall 92 and the second wall 94 is narrow, as it increases the space for accommodating the electric wire 10. For example, the rib 100 may protrude beyond the center position between the first wall 92 and the second wall 94, and the retaining piece 110 may protrude to an extent that does not exceed the center position between the first wall 92 and the second wall 94.

[0063] Alternatively, the protruding length of the rib and the protruding length of the holding piece may be the same, or the protruding length of the rib may be greater than the protruding length of the holding piece. For example, the protruding length of the rib 200 (corresponding to the rib 100) formed on the paths PZ2 and PL2 is greater than the protruding length of the holding piece 210 (corresponding to the holding piece 110).

[0064] An opening 90h is formed in an area of ​​the bottom 90 that includes an area where the pressing piece 110 is projected onto the bottom 90. By using the opening 90h, it becomes easy to mold the pressing piece 110 at a position away from the bottom 90.

[0065] The number of the ribs 100 and the holding pieces 110 is arbitrary. In this embodiment, the rib 100 includes a first rib 100a and a second rib 100b. Hereinafter, the rib 100 will be distinguished as the first rib 100a and the second rib 100b as necessary. In the extension direction of the first wall 92, the holding piece 110 is located between the first rib 100a and the second rib 100b. As described above, the first rib 100a and the second rib 100b are located apart from each other on both sides of the holding piece 110. Therefore, a gap through which the electric wire 10 can pass is formed between the holding piece 110 and the first rib 100a, and a gap through which the electric wire 10 can pass is also formed between the holding piece 110 and the second rib 100b.

[0066] In a plan view, in the direction along the path PZ3, the gap between the first rib 100a and the second wall 94, the gap between the first rib 100a and the pressing piece 110, the gap between the pressing piece 110 and the first wall 92, the gap between the second rib 100b and the pressing piece 110, and the gap between the second rib 100b and the second wall 94 are arranged in this order. The electric wire 10 is bent into a U-shape according to the arrangement of the gaps and pushed between the first wall 92 and the second wall 94 toward the bottom 90. Then, the electric wire 10 passes through the gaps, passes over the pressing piece 110 toward the bottom 90, and is disposed in a space surrounded by the upper surface of the bottom 90, the inner surface of the pressing piece 110, the tip of the rib 100, and the inner surface of the second wall 94.

[0067] The holding piece may protrude from the first wall and the rib may protrude from the second wall, or the holding piece may protrude from both the first wall and the second wall.

[0068] <About wire holding work> An example of the operation of holding the electric wire 10 in the electric wire holding member 20 will be described.

[0069] For example, the terminal 18 is set in the terminal setting portion 32. The electric wire 10 extending from the terminal 18 is arranged along the paths PZ1, PZ2, and PZ3.

[0070] In each of the paths PZ2 and PZ3, the electric wire 10 is passed through the gap between the ribs 100 and 200 and the retaining pieces 110 and 210 and pushed inside the retaining pieces 110 and 210.

[0071] For example, in path PZ3, the electric wire 10 is bent into a U-shape and pushed into the gap between the first rib 100a and the second wall 94, the gap between the first rib 100a and the retaining piece 110, the gap between the retaining piece 110 and the first wall 92, the gap between the second rib 100b and the retaining piece 110, and the gap between the second rib 100b and the second wall 94 (see the electric wire 10 indicated by the two-dot chain line in Figure 5).

[0072] The electric wire 10 may be forcibly bent by an external force that generates a U-shaped bend, or may be bent into a U-shape by being pressed against the ribs 100a, 100b and the holding piece 110.

[0073] When the electric wire 10 passes through the gap, it is disposed inside the retaining piece 110 in a space surrounded by the bottom 90, the first wall 92, and the second wall 94. Thereafter, the electric wire 10 is deformed so as to approach a straight state. The bending deformation to approach the straight state may be achieved by pulling the electric wire 10 in the longitudinal direction. At least a part of the U-shaped bending is a bending using elastic deformation, and the bending deformation to approach the straight state may be achieved by restoring the electric wire 10 to an approximate straight state after passing through the gap.

[0074] When the electric wire 10 approaches a straight state, the electric wire 10 is more likely to be disposed on the second wall 94 side than the tip edges of the ribs 100a, 100b, even between the ribs 100a, 100b. Therefore, even if the electric wire 10 tries to slip through between the first wall 92 and the second wall 94 to the side opposite to the bottom 90, the electric wire 10 comes into contact with the retaining piece 110. This prevents the electric wire 10 from slipping out from between the first wall 92 and the second wall 94.

[0075] When a plurality of electric wires 10 are to be held, the above steps are repeated so that the plurality of electric wires 10 are sequentially accommodated between the first wall 92 and the second wall 94.

[0076] In this embodiment, the electric wire 10 is held along paths PZ1, PZ2, and PZ3. In addition, the electric wire 10 is held along paths PL1 and PL2.

[0077] Each electric wire 10 may reach the lead-out portion 28 and be bound and fixed to the lead-out portion 28 by a binding member 29 .

[0078] <About the wire positioning part> In the paths PZ2, PZ3, and PL2, the electric wire 10 is preferably held in a nearly straight state so as not to be pulled out.

[0079] Therefore, the wire holding member 20 has a first wire positioning portion 130 and a second wire positioning portion 140 that position the wire 10 at a fixed position, and the rib 100 and the clamping piece 110 are preferably positioned between the first wire positioning portion 130 and the second wire positioning portion 140 along the path of the wire 10.

[0080] Focusing on the electric wire 10 held along the paths PZ1, PZ2, and PZ3, the structure in which the terminals 18 are held by the terminal set portion 32 functions as a first electric wire positioning portion 130 that positions the electric wire 10 at a fixed position. In addition, the bundling member 29 that bundles and fixes the electric wire 10 to the drawn-out portion 28 can function as a second electric wire positioning portion 140.

[0081] It is preferable that the first electric wire positioning portion 130 and the second electric wire positioning portion 140 position and hold the electric wire 10 in a state in which the electric wire 10 is stretched, without applying excessive tension to the electric wire 10.

[0082] When the electric wire 10 is positioned by the first electric wire positioning portion 130 and the second electric wire positioning portion 140, deformation that would cause the electric wire 10 to become loose is unlikely to occur between the first electric wire positioning portion 130 and the second electric wire positioning portion 140. Therefore, the electric wire 10 is likely to be kept in a state close to a straight state. Therefore, the electric wire 10 is unlikely to deform into a shape that allows it to pass through the gap between the rib 100 and the retaining piece 110, and is unlikely to slip out from between the first wall 92 and the second wall 94.

[0083] The configuration for positioning and holding the electric wire 10 may be a configuration using the fixing structure of the terminal, a configuration using a binding member, as described above, or a configuration in which the electric wire is clamped with an elastic piece, or a structure in which the electric wire is wrapped around a protrusion and fixed.

[0084] The electric wires 10 along the paths PL1 and PL2 are also positioned and held by the first electric wire positioning portion 130 using the terminal 18 and the second electric wire positioning portion 140 using the bundling member 29.

[0085] <Regarding the positional relationship of the restraining pieces in curved paths> A rib 100 projects from the first wall 92, and a retaining piece 110 projects from the second wall 94. Thus, the electric wire 10 is guided to pass through a position away from the first wall 92.

[0086] When the electric wire 10 is held along a bending path, it is preferable that the electric wire 10 passes through the inside of the bending path, which makes it easier to shorten the path of the electric wire 10.

[0087] For example, attention is focused on the paths PZ2 and PZ3. The paths PZ2 and PZ3 are paths that are bent in an L shape, and the electric wire 10 is held along the paths PZ2 and PZ3 that are bent in an L shape.

[0088] In the path PZ3, the second wall 94 and the retaining piece 110 are located inside the curved paths PZ2 and PZ3. More specifically, the second wall 94 is a part of the second surrounding wall portion 40, and the retaining piece 110 protrudes from the second wall 94.

[0089] In addition, the first wall 92 and the rib 100 are located on the outside in the path PZ3. More specifically, the first wall 92 is a part of the second outer wall portion 60, and the rib 100 protrudes from the first wall 92.

[0090] In path PZ2, the pressing piece 210 and the second wall 94 (part of the second surrounding wall portion 40) on which the pressing piece 210 is formed are located inside, and the rib 200 and the first wall (part of the first surrounding wall portion 30) on which the rib 200 is formed are located outside.

[0091] Therefore, the electric wire 10 can pass through the curved paths PZ2 and PZ3 at positions closer to the inside, and the path length of the electric wire 10 can be shortened.

[0092] <Effects, etc.> According to the electric wire holding member 20 configured as described above, the rib 100 as the first protrusion and the pressing piece 110 as the second protrusion are positioned apart from each other in the extending direction of the first wall 92. Therefore, the electric wire 10 can be passed between the rib 100 and the pressing piece 110 at an angle with respect to the extending direction of the first wall 92. Furthermore, when the electric wire 10 passing between the rib 100 and the pressing piece 110 toward the bottom 90 is brought closer to the extending direction of the first wall 92 in a direction parallel to the extending direction of the first wall 92, the electric wire 10 is disposed between the bottom 90 and the pressing piece 110 that protrudes away from the bottom 90. Therefore, deformation of the structural portion that holds the electric wire 10 can be suppressed when the electric wire 10 is held. In other words, the electric wire 10 can be held without deforming the pressing piece 110 or the like. Therefore, the electric wire holding member 20 is less likely to be damaged.

[0093] For example, it is assumed that the electric wire holding member 20 is formed from fiber reinforced resin. Fiber reinforced resin is not easily elastically deformed, and it is difficult to impart elasticity to the electric wire holding member 20. In such a case, the electric wire 10 can be held while suppressing elastic deformation of the pressing piece 110, and damage to the electric wire holding member 20 can be effectively suppressed.

[0094] When viewed along the extending direction of the first wall 92, the tip of the rib 100 and the tip of the holding piece 110 overlap each other, so the electric wire 10, which is in a state approaching a parallel posture with the first wall 92, is unlikely to pass between the rib 100 and the holding piece 110. Therefore, the electric wire 10 is firmly held.

[0095] Moreover, since the first protrusion is a rib 100 extending from the bottom 90 toward the tip side of the first wall 92, the first wall 92 can be reinforced by the rib 100. Furthermore, a space for accommodating the electric wire 10 can be secured between the bottom 90 and the retaining piece 110 that protrudes at a position away from the bottom 90.

[0096] Furthermore, in order to form the pressing piece 110 at a position away from the bottom 90, it is conceivable to form, for example, an opening 90h in the bottom 90. If the first protrusion is a rib 100, the rib 100 can be easily formed without forming an opening in the bottom 90 in order to form the rib 100.

[0097] Furthermore, if the protruding length L1 of the rib 100 is smaller than the protruding length L2 of the retaining piece 110, the distance between the tip edge of the rib 100 and the second wall 94 can be increased between the bottom 90 and the retaining piece 110, making it easier to increase the storage space for the electric wire 10.

[0098] Furthermore, if the rib 100 includes a first rib 100a and a second rib 100b and the holding piece 110 is located between the first rib 100a and the second rib 100b, when the electric wire 10 is brought close to a straight state between the first wall 92 and the second wall 94, the first rib 100a and the second rib 100b will keep the electric wire 10 located closer to the front side than the tip of the holding piece 110. Therefore, the electric wire 10 is more reliably held by the holding piece 110.

[0099] Furthermore, since the holding piece 110 includes the tapered tip 112, it is easy to ensure a gap for passing the electric wire 10 between the tapered tip 112 of the holding piece 110 and the first rib 100a, and between the tapered tip 112 and the second rib 100b. This facilitates the work of holding the electric wire 10. Furthermore, the electric wire 10 is less likely to come into contact with the holding piece 110 locally.

[0100] In addition, in the bending paths PZ2 and PZ3, the second wall 94 and the retaining piece 110 are located on the inner side, and the first wall 92 and the rib 100 are located on the outer side. Therefore, the electric wire 10 tends to pass near the inner side in the bending paths PZ2 and PZ3. This makes it easy to shorten the length of the electric wire 10.

[0101] In addition, the rib 100 and the retaining piece 110 are located between the electric wire positioning portions 130, 140. Therefore, the electric wire 10 can be easily maintained in a taut state between the electric wire positioning portions 130, 140. This makes it difficult for the electric wire 10 to pass between the rib 100 and the retaining piece 110, and the electric wire 10 is firmly held.

[0102] [Variations] The electric wire holding member may hold an electric wire in which a plurality of electric wires are bundled together.

[0103] It is not essential that the wire holding member hold the terminal, and the wire holding member may be a protector that protects the wire.

[0104] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
