[0010] [Embodiment Mode] An embodiment of the present invention will be described with reference to Figures 1 to 9. Note that the embodiment described below is shown as a preferred specific example for carrying out the present invention, and while there are some parts that specifically exemplify various technical matters that are technically preferable, the technical scope of the present invention is not limited to this specific embodiment.

[0011] 1 is a perspective view of the wiring member 1 as viewed from diagonally above D2. Although details will be described later, the holder 2 constituting the wiring member 1 is configured so that, when in a single state, it can be placed on a placement member (reference number 10 in FIG. 9) at a placement surface (reference numbers 472a and 572a in FIG. 9 described later) formed on the holder 2, and a direction perpendicular to this placement surface is defined as a vertical direction D, one side of the vertical direction D to which the placement surface faces is defined as a lower side D1, and the opposite side is defined as an upper side D2. Note that the expressions "upper" and "lower" do not limit the orientation with respect to the vertical direction when, for example, an electric wire 7 is assembled to the holder 2 and used.

[0012] 1, wiring member 1 includes holder 2, a plurality of electric wires 7 held by holder 2, and a plurality of molding resins that integrate the plurality of electric wires 7 with holder 2 at a plurality of locations. In this embodiment, wiring member 1 includes one holder 2, six electric wires 7 held by holder 2, and first to third molding resins 81-83 that integrate the six electric wires 7 with holder 2 at three locations.

[0013] Fig. 2 is a perspective view of the holder 2 and the plurality of electric wires 7 as viewed obliquely from the upper side D2. Fig. 3 is a perspective view of the holder 2 and the plurality of electric wires 7 as viewed obliquely from the lower side D1. Fig. 4 is a side view of the holder 2 and the plurality of electric wires 7. In Fig. 4, the outer positions of the first to third molding resins 81 to 83 are indicated by two-dot chain lines.

[0014] 2 to 4, the holder 2 includes a plurality of holding portions that hold six electric wires 7 at positions spaced apart from one another, and a connecting portion that connects the holding portions together. In this embodiment, the holder 2 includes first to third holding portions 3 to 5 as holding portions, and includes a first connecting portion 61 that connects the first holding portion 3 and the second holding portion 4, and a second connecting portion 62 that connects the second holding portion 4 and the third holding portion 5, as connecting portions. As a material for the holder 2, a resin having excellent mechanical strength, heat resistance, and electrical insulation, such as glass fiber-reinforced PPS (polyphenylene sulfide), is preferably used.

[0015] The first holding portion 3 holds two of the six electric wires 7, the second holding portion 4 holds four of the six electric wires 7, and the third holding portion 5 holds all six electric wires 7.

[0016] Fig. 5 is a perspective view of the holder 2 as viewed from an oblique upper side D2, Fig. 6 is a perspective view of the holder 2 as viewed from an oblique lower side D1, and Fig. 7 is a cross-sectional view taken along the line VII-VII in Fig. 1.

[0017] In the first holding part 3, an upper arrangement groove 31 that opens to the upper side D2 as shown in FIG. 5 and a lower arrangement groove 32 that opens to the lower side D1 as shown in FIG. 6 are formed. The upper arrangement groove 31 and the lower arrangement groove 32 are formed along the same direction. As shown in FIG. 7, the upper arrangement groove 31 and the lower arrangement groove 32 are formed at positions where they overlap each other in the up-down direction D. Hereinafter, when the axial direction is referred to with respect to the first holding part 3, it means a direction along the upper arrangement groove 31 and the lower arrangement groove 32 of the first holding part 3. In addition, when the width direction is referred to with respect to the first holding part 3, it means a direction perpendicular to the up-down direction D and the axial direction of the first holding part 3.

[0018] 7, different electric wires 7 are arranged in the upper arrangement groove 31 and the lower arrangement groove 32. Each of the upper arrangement groove 31 and the lower arrangement groove 32 is formed so as to fit the surface of the electric wire 7 to be arranged. In this embodiment, the electric wire 7 has a circular cross section perpendicular to the longitudinal direction of the electric wire 7, and each of the upper arrangement groove 31 and the lower arrangement groove 32 is formed so as to have a curved surface such that a cross section perpendicular to the axial direction is an arc shape.

[0019] 5 and 6, the side surfaces 33 located on both sides in the width direction of the first holding part 3 have concave surfaces 331 formed to be concave inward in the width direction. In addition, the first holding part 3 has opposing surfaces 34 that are opposed to each other in the axial direction with the inner region of the concave surface 331 interposed therebetween.

[0020] 4, the axial region between opposing surfaces 34 of first holding part 3 is embedded portion 35 embedded in first molded resin 81, and the portions on both axial sides of embedded portion 35 of first holding part 3 are exposed portions 36 exposed from first molded resin 81. Opposing surface 34 defines a cavity (i.e., a space in which first molded resin 81 is molded) together with a metal mold for molding first molded resin 81 when first molded resin 81 is molded, and blocks the flow of molten resin that becomes first molded resin 81 when first molded resin 81 is molded. As a result, the axial region between opposing surfaces 34 of first holding part 3 becomes embedded portion 35 embedded in first molded resin 81.

[0021] 6 and 7, the first holding portion 3 has lower outer walls 37 located on both sides of the lower groove 32. The lower outer walls 37 define the lower groove 32 from the sides.

[0022] The lower outer wall 37 has an embedded lower outer wall 371 formed in the center in the axial direction and constituting a part of the embedded portion 35, and exposed lower outer walls 372 formed on both sides of the embedded lower outer wall 371 in the axial direction and constituting a part of the exposed portion 36. As shown in Fig. 7, the position of a lower surface 371a of the embedded lower outer wall 371 is located on the upper side D2 than the position of a lower surface 372a of the exposed lower outer wall 372.

[0023] 5 and 7, the first holding portion 3 has upper outer walls 38 located on both sides of the upper arrangement groove 31. The upper outer walls 38 define the upper arrangement groove 31 from the sides.

[0024] The upper outer wall 38 has a buried upper outer wall 381 formed in the center in the axial direction and constituting a part of the buried portion 35, and exposed upper outer walls 382 formed on both sides of the buried upper outer wall 381 in the axial direction and constituting a part of the exposed portion 36. As shown in Fig. 7, the position of an upper surface 381a of the buried upper outer wall 381 is located on a lower side D1 than the position of an upper surface 382a of the exposed upper outer wall 382.

[0025] The second holding part 4 has two upper arrangement grooves 41 as shown in FIG. 5 and two lower arrangement grooves 42 as shown in FIG. 6. The two upper arrangement grooves 41 are formed in parallel along the same direction, and similarly, the two lower arrangement grooves 42 are formed in parallel along the same direction. The upper arrangement grooves 41 and the lower arrangement grooves 42 are formed in the same direction. The two upper arrangement grooves 41 and the two lower arrangement grooves 42 are arranged in the same direction. FIG. 8 is a cross-sectional view taken along the arrow VIII-VIII in FIG. 1. As shown in FIG. 8, the two upper arrangement grooves 41 and the two lower arrangement grooves 42 are formed at positions overlapping each other in the up-down direction D. Hereinafter, when the axial direction is mentioned with respect to the second holding part 4, it means the direction along the upper arrangement grooves 41 and the lower arrangement grooves 42 of the second holding part 4. Moreover, when the width direction is referred to with respect to the second holding portion 4, it means a direction perpendicular to the up-down direction D and the axial direction of the second holding portion 4.

[0026] As shown in Fig. 8, different electric wires 7 are arranged in the two upper arrangement grooves 41 and the two lower arrangement grooves 42. As shown in Fig. 2, a common electric wire 7 is arranged in one upper arrangement groove 41 of the second holding part 4 and one upper arrangement groove 31 of the first holding part 3. In addition, as shown in Fig. 3, a common electric wire 7 is arranged in one lower arrangement groove 42 of the second holding part 4 and one lower arrangement groove 32 of the first holding part 3.

[0027] 8, each of the upper arrangement groove 41 and the lower arrangement groove 42 is formed so as to follow the surface of the electric wire 7 to be arranged. As described above, the electric wire 7 has a circular cross section, and each of the upper arrangement groove 41 and the lower arrangement groove 42 is formed so as to have a curved surface such that a cross section perpendicular to the axial direction is an arc shape.

[0028] 5 and 6, the side surfaces 43 located on both sides in the width direction of the second holding part 4 have concave surfaces 431 formed to be concave inward in the width direction. In addition, the second holding part 4 has opposing surfaces 44 that are opposed to each other in the axial direction with the inner region of the concave surface 431 interposed therebetween.

[0029] 4, the axial region between opposing surfaces 44 in second holding part 4 is embedded portion 45 embedded in second molded resin 82, and the portions on both axial sides of embedded portion 45 in second holding part 4 are exposed portions 46 exposed from second molded resin 82. Opposing surface 44 defines a cavity (i.e., a space in which second molded resin 82 is molded) together with a mold for molding second molded resin 82 when second molded resin 82 is molded, and blocks the flow of molten resin that becomes second molded resin 82 when second molded resin 82 is molded. As a result, the axial region between opposing surfaces 44 in second holding part 4 becomes embedded portion 45 embedded in second molded resin 82.

[0030] 6 and 8, the second holding portion 4 has a lower intermediate wall 47 interposed between the two lower arrangement grooves 42, and a lower outer wall 48 formed on the opposite side of each lower arrangement groove 42 from the lower intermediate wall 47. The lower intermediate wall 47 and the lower outer wall 48 laterally define the lower arrangement groove 42.

[0031] The lower intervening wall 47 has a lower base portion 471 and a lower protruding portion 472 protruding from the lower base portion 471 to the lower side D1. As shown in FIG. 8, the height of the lower surface 471a of the lower base portion 471 is aligned with the height of a lower surface 482a of an exposed lower outer wall 482 (described later) of the lower outer wall 48 in the up-down direction D. As shown in FIG. 6, in this embodiment, the lower protruding portion 472 is formed in a partial region of the lower intervening wall 47 in the axial direction. Specifically, the lower protruding portion 472 is formed in the center of the lower intervening wall 47 except for both ends in the axial direction, and is formed long in the axial direction. As shown in FIG. 4, the axial length of the lower protruding portion 472 can be, for example, half or more of the length of the embedded portion 45 in the axial direction and less than the axial length of the embedded portion 45.

[0032] 6 and 8, the lower surface 472a of the lower protrusion 472 is formed in a flat shape perpendicular to the up-down direction D. When viewed in a cross section passing through the lower protrusion 472 and perpendicular to the axial direction, such as the cross section shown in FIG. 8, the lower surface 472a of the lower protrusion 472 is configured to be wider than the lower surface of the lower outer wall 48 (i.e., a lower surface 481a of a buried lower outer wall 481 described later). Corners 472b located on both sides of the lower surface 472a of the lower protrusion 472 in the width direction are rounded into a curved shape. This prevents the electric wire 7 from being damaged by the corners 472b when the electric wire 7 is assembled into the lower arrangement groove 42.

[0033] 6, the lower outer wall 48 has an embedded lower outer wall 481 formed in the center in the axial direction and constituting a part of the embedded portion 45, and exposed lower outer walls 482 formed on both sides of the embedded lower outer wall 481 in the axial direction and constituting a part of the exposed portion 46. As shown in FIG. 8, the position of a lower surface 481a of the embedded lower outer wall 481 is located on the upper side D2 than the position of a lower surface 482a of the exposed lower outer wall 482.

[0034] 5 and 8, the second holding portion 4 has an upper intermediate wall 49 interposed between the two upper arrangement grooves 41, and an upper outer wall 40 formed on the opposite side of each upper arrangement groove 41 from the upper intermediate wall 49. The upper intermediate wall 49 and the upper outer wall 40 laterally define the upper arrangement groove 41.

[0035] The upper intermediate wall 49 has an upper base portion 491 and an upper protruding portion 492 protruding from the upper base portion 491 to the upper side D2. As shown in FIG. 8, the height of the upper surface 491a of the upper base portion 491 is aligned with the height of an upper surface 402a of an exposed upper outer wall 402 (described later) of the upper outer wall 40 in the up-down direction D. As shown in FIG. 5, in this embodiment, the upper protruding portion 492 is formed in a part of the upper intermediate wall 49 in the axial direction. Specifically, the upper protruding portion 492 is formed in the center of the upper intermediate wall 49 except for both ends in the axial direction, and is formed long in the axial direction. As shown in FIG. 4, the axial length of the upper protruding portion 492 can be, for example, half or more of the length of the embedded portion 45 in the axial direction and less than the axial length of the embedded portion 45.

[0036] As shown in Fig. 5 and Fig. 8, the upper surface 492a of the upper protrusion 492 is formed in a plane perpendicular to the up-down direction D. When viewed in a cross section passing through the lower protrusion 472 and perpendicular to the axial direction, such as the cross section shown in Fig. 8, the upper surface 492a of the upper protrusion 492 is configured to be wider than the upper surface of the upper outer wall 40 (i.e., the upper surface 401a of the buried upper outer wall 401 described later). Corners 492b located on both sides of the width direction of the upper surface 492a of the upper protrusion 492 are rounded into a curved shape. This prevents the electric wire 7 from being damaged by the corners 492b when the electric wire 7 is assembled into the upper arrangement groove 41.

[0037] 5, the upper outer wall 40 has a buried upper outer wall 401 formed in the center in the axial direction and constituting a part of the buried portion 45, and exposed upper outer walls 402 formed on both sides of the buried upper outer wall 401 in the axial direction and constituting a part of the exposed portion 46. As shown in FIG. 8, the position of the upper surface 401a of the buried upper outer wall 401 is located on the lower side D1 than the position of the upper surface 402a of the exposed upper outer wall 402.

[0038] The third holding part 5 has three upper arrangement grooves 51 as shown in FIG. 5 and three lower arrangement grooves 52 as shown in FIG. 6. An upper intermediate wall 59 is formed between two adjacent upper arrangement grooves 51 of the three upper arrangement grooves 51, and a lower intermediate wall 57 is formed between two adjacent lower arrangement grooves 52 of the three lower arrangement grooves 52. An upper outer wall 50 is formed on the opposite side of the upper intermediate wall 59 in the upper arrangement groove 51 located at the end of the three upper arrangement grooves 51, and a lower outer wall 58 is formed on the opposite side of the lower intermediate wall 57 in the lower arrangement groove 52 located at the end of the three lower arrangement grooves 52. The configuration of each part of the third holding part 5 is the same as that of the second holding part 4. Among the components of the third holding unit 5, those that are similar to the components of the second holding unit 4 are represented by reference numerals in which the first digit "4" of the reference numerals of the components of the second holding unit 4 is changed to "5."

[0039] 5 and 6, the first holding portion 3 and the second holding portion 4 are connected by a first connecting portion 61. The first connecting portion 61 is formed in a plate shape having a thickness in the vertical direction D. As shown in FIGS. 2 and 3, the first connecting portion 61 is interposed between the two electric wires 7 held by the first holding portion 3 and the second holding portion 4.

[0040] 5 and 6, the second holding portion 4 and the third holding portion 5 are connected by a second connecting portion 62. The second holding portion 4 is formed in a plate shape having a thickness in the up-down direction D. As shown in FIGS. 2 and 3, the second connecting portion 62 is interposed between the two electric wires 7 held in the upper arrangement grooves 41, 51 of the second holding portion 4 and the third holding portion 5, respectively, and the two electric wires 7 held in the lower arrangement grooves 42, 52 of the second holding portion 4 and the third holding portion 5, respectively.

[0041] Fig. 9 is a side view of the holder 2 placed on the mounting member 10. As shown in Fig. 9, the holder 2 can be placed on the mounting member 10 in a single state. For example, the mounting member 10 can be a storage member for storing the holder 2, or a mounting table provided in a place where an operation of assembling a plurality of electric wires 7 to the holder 2 is performed. The upper surface 101 of the mounting member 10 on which the holder 2 is placed is formed in a flat shape.

[0042] At least one of the first to third holding parts 3 to 5 is a mounting holding part having a mounting surface formed thereon that can be mounted on the mounting member 10. The mounting surface is a surface that is aligned in height with the lower end positions of other parts of the holder. In this embodiment, the lower surface 472a of the lower protrusion 472 of the second holding part 4 and the lower surfaces 572a of the two lower protrusions 572 of the third holding part 5 are mounting surfaces, and both the second holding part 4 and the third holding part 5 constitute a mounting holding part. That is, the mounting surface (i.e., the lower surface 472a) of the second holding part 4 and the two mounting surfaces (i.e., the lower surface 572a) of the third holding part 5 are formed at the lower end position of the holder 2 and are aligned in height with each other. In this embodiment, as shown in FIG. 9, the distance L1 in the vertical direction D between the second connecting part 62 and the lower surface 472a and the distance L2 in the vertical direction D between the second connecting part 62 and the lower surface 572a are aligned. In addition, in Figure 9, the position when the lower surface of the second connecting portion 62 is virtually extended in the longitudinal direction of the second connecting portion 62 is shown by a dotted line on the second retaining portion 4 and the third retaining portion 5.

[0043] When the heights of a plurality of parts are uniform, this includes not only the case where the positions of the plurality of parts in the vertical direction D are strictly the same, but also the case where, for example, the plurality of parts are designed to be formed at the same position in the vertical direction D, but the heights of the plurality of parts are slightly different due to manufacturing tolerances, etc. For example, when the heights of a plurality of mounting surfaces are uniform, this may include the case where the length in the vertical direction D between the mounting surface located at the lowest side D1 and the mounting surface located at the highest side D2 among the plurality of mounting surfaces is 0.7 mm or less. In addition, when the heights of a plurality of mounting surfaces are uniform, this may include the case where the length in the vertical direction D between the mounting surface located at the lowest side D1 and the mounting surface located at the highest side D2 among the plurality of mounting surfaces is 25% or less (more preferably, 10% or less) of the diameter of the electric wire 7.

[0044] In this embodiment, the holder 2 has a hardness that allows it to maintain its own shape without bending under its own weight when placed on the mounting member 10 by itself. In this embodiment, when the holder 2 by itself is placed on the mounting member 10, the first holding part 3 is floating above the mounting member 10.

[0045] 2 to 4, six electric wires 7 are held by the holder 2. The portion of each of the six electric wires 7 held by the holder 2 is at the lowest position of the respective electric wire 7. In this embodiment, the center portion of each of the six electric wires 7 is formed on a plane perpendicular to the up-down direction D, and both side portions are bent upward D2, with the center portion being formed at the lowest position of each electric wire 7.

[0046] Each of the six electric wires 7 has a conductor portion 71 made of a conductive metal or the like, and an electrically insulating coating 72 that covers the surface of the conductor portion 71. The conductor portion 71 is made of, for example, copper or a copper alloy, and the coating 72 can be, for example, an enamel coating.

[0047] Conductor portion 71 has enough rigidity to maintain its own shape. In this embodiment, conductor portion 71 is formed into a predetermined shape by pressing a solid round wire with a circular cross section. Both ends of conductor portion 71 are exposed from coating 72 and serve as terminal portions to be connected to a connection object. In this embodiment, the terminal portions are formed into a plate shape by pressing so as to be easily connected to a connection object. Note that the configuration of electric wire 7 is not limited to the above-mentioned configuration, and conductor portion 71 may be formed of a twisted wire or a rectangular wire, for example.

[0048] All six of the electric wires 7 are held by the third holding portion 5, four are held by the second holding portion 4, and two are held by the first holding portion 3. The electric wires 7 are fitted into the upper arrangement grooves 31, 41, 51 or the lower arrangement grooves 32, 42, 52. In this embodiment, the electric wires 7 are loosely fitted into the upper arrangement grooves 31, 41, 51 or the lower arrangement grooves 32, 42, 52.

[0049] 4, in a state in which the six electric wires 7 are fitted into the upper arrangement grooves 31, 41, 51 and the lower arrangement grooves 32, 42, 52 of the holder 2, the lower surface 472a (i.e., the placement surface) of the lower protrusion 472 of the second holding part 4 is aligned in height with the lower end position of the portion of the electric wires 7 arranged in the lower arrangement groove 42 of the second holding part 4. In addition, the upper surface 492a of the upper protrusion 492 of the upper intermediate wall 49 of the second holding part 4 is aligned in height with the upper end position of the portion of the electric wires 7 arranged in the upper arrangement groove 41 of the second holding part 4. The same is true for the third holding part 5.

[0050] 1, the six electric wires 7 and the holder 2 are integrated by first to third molded resins 81 to 83. The first molded resin 81 is formed by molding the first holding portion 3 and the two electric wires 7 held by the first holding portion 3. That is, the first molded resin 81 is formed by arranging the first holding portion 3 and the two electric wires 7 held by the first holding portion 3 in a metal mold, injecting molten resin into the metal mold, and allowing it to harden. The first molded resin 81 covers the first holding portion 3 and the two electric wires 7 held by the first holding portion 3 in an axial region between a pair of opposing surfaces 34.

[0051] The second molded resin 82 is formed by molding the second holding portion 4 and the four electric wires 7 held by the second holding portion 4. That is, the second molded resin 82 is formed by arranging the second holding portion 4 and the four electric wires 7 held by the second holding portion 4 in a metal mold, injecting molten resin into the metal mold, and allowing it to harden. The second molded resin 82 covers the second holding portion 4 and the four electric wires 7 held by the second holding portion 4 in the axial region between the pair of opposing surfaces 44.

[0052] Third molded resin 83 is formed by molding third holding portion 5 and six electric wires 7 held by third holding portion 5. That is, third molded resin 83 is formed by arranging third holding portion 5 and five electric wires 7 held by third holding portion 5 in a metal mold, injecting molten resin into the metal mold, and allowing it to harden. Third molded resin 83 covers third holding portion 5 and six electric wires 7 held by third holding portion 5 in an axial region between a pair of opposing surfaces 54.

[0053] The first to third molding resins 81 to 83 may be made of the same resin as the holder 2, for example, or may be made of a resin different from that of the holder 2.

[0054] The wiring member 1 of this embodiment is mounted on an automobile such as an electric automobile or a hybrid automobile, and is connected to a motor that generates a driving force for running. For example, the wiring member 1 connects a coil end of a stator of the motor to an electrode of a terminal block of the motor. For example, two electric wires 7 of the wiring member 1 are connected to a U-phase winding of the stator, another two electric wires 7 are connected to a V-phase winding of the stator, and the remaining two electric wires 7 are connected to a W-phase winding of the stator. Note that the use of the wiring member 1 is not limited to this.

[0055] (Functions and Effects of the Embodiments) In this embodiment, at least one of the multiple holding parts of the holder 2 (the second holding part 4 and the third holding part 5 in this embodiment) is a mounting holding part having a mounting surface that can be mounted on the mounting member 10. The mounting surface of the mounting holding part is aligned in height with the lower end position of the other part of the holder 2. For example, in this embodiment, the lower surface 472a as the mounting surface of the second holding part 4 as the mounting holding part is aligned in height with the lower surface 572a that is the lower end position of the other part of the holder 2, and the lower surface 572a as the mounting surface of the third holding part 5 as the mounting holding part is aligned in height with the lower surface 472a that is the lower end position of the other part of the holder 2. Therefore, it is possible to improve the stability when the holder 2 alone is mounted on the mounting member 10.

[0056] Moreover, at least one mounting holder has at least two lower arrangement grooves 42, 52, a lower intermediate wall 47, 57 interposed between the at least two lower arrangement grooves 42, 52, and a lower outer wall 48, 58 formed on the lower arrangement groove 42, 52 located at the end of the at least two lower arrangement grooves 42, 52 on the opposite side to the lower intermediate wall 47, 57. The lower intermediate wall 47, 57 has a lower protruding portion 472, 572 protruding downward D1 beyond the lower outer wall 48, 58. The lower surfaces 472a, 572a of the lower protruding portions 472, 572 form the mounting surface. In this way, by extending the lower intervening walls 47, 57 to the lower side D1 to form the mounting surface, the electric wires 7 arranged in the lower arrangement grooves 42, 52 adjacent to the lower intervening walls 47, 57 are prevented from falling off from the lower arrangement grooves 42, 52. For example, when the second holding part 4 is held by a robot hand or the like from both sides in the width direction in a state in which a plurality of electric wires 7 are held in the holder 2, the electric wires 7 arranged in the lower arrangement grooves 42 of the second holding part 4 are pushed toward the lower intervening wall 47, and at this time, the lower intervening wall 47 serves as a wall for preventing the electric wires 7 from falling off. In addition, since the lower intervening walls 47, 57 intervened between the lower arrangement grooves 42, 52 are formed at a relatively central position of the mounting holding part, the lower intervening walls 47, 57 forming the mounting surface make it possible to mount the holder 2 alone on the mounting member 10 more stably.

[0057] Further, the lower intervening walls 47, 57 have lower protrusions 472, 572 in a partial region of the lower intervening walls 47, 57 in the groove formation direction of the lower arrangement grooves 42, 52 adjacent to the lower intervening walls 47, 57. If the lower protrusions 472, 572 protruding from the holder 2 are too long in the groove formation direction, the assembling property of the electric wire 7 to the holder 2 may be hindered, but in this embodiment, the assembling property of the electric wire 7 to the holder 2 is prevented from being hindered.

[0058] Moreover, at least one mounting holder has at least two upper arrangement grooves 41,51, an upper intermediate wall 49,59 interposed between the at least two upper arrangement grooves 41,51, and an upper outer wall 40,50 formed on the opposite side to the upper intermediate wall 49,59 in the upper arrangement groove 41,51 located at the end of the at least two upper arrangement grooves 41,51. The upper intermediate wall 49,59 has an upper protruding portion 492,592 protruding toward the upper side D2 beyond the upper outer wall 40,50. This prevents the electric wire 7 arranged in the upper arrangement groove 41,51 adjacent to the upper intermediate wall 49,59 from falling off from the upper arrangement groove 41,51.

[0059] Further, the upper intermediate walls 49, 59 have upper protrusions 492, 592 in a partial region of the upper intermediate walls 49, 59 in the groove formation direction of the upper arrangement grooves 41, 51 adjacent to the upper intermediate walls 49, 59. If the upper protrusions 492, 592 protruding from the holder 2 are too long in the groove formation direction, the ease of assembling the electric wire 7 to the holder 2 may be hindered. However, in this embodiment, the ease of assembling the electric wire 7 to the holder 2 is prevented from being hindered.

[0060] Furthermore, the mounting surface formed by the lower surfaces 472a, 572a of the lower protrusions 472, 572 of the lower intervening walls 47, 57 of the mounting holder is aligned in height with the lower end position of the portion of the electric wire 7 arranged in the lower arrangement groove 42, 52. Furthermore, the upper surfaces 492a, 592a of the upper protrusions 492, 592 of the upper intervening walls 49, 59 are aligned in height with the upper end position of the portion of the electric wire 7 arranged in the upper arrangement groove 41, 51. Therefore, when the mounting holder of the holder 2 with the multiple electric wires 7 attached thereto is grasped by a robot hand or the like, rattling of the holder 2 and the multiple electric wires 7 is suppressed.

[0061] As described above, according to this embodiment, it is possible to provide a holder and a wiring member that can improve the stability when the holder alone is placed on a placement member.

[0062] [Variations] In the embodiment, the lower surface 472a of the lower intervening wall 47 of the second holding portion 4 and the lower surface 572a of the lower intervening wall 57 of the third holding portion 5 constitute the mounting surface, but this is not limited thereto. For example, the mounting surface of the second holding portion 4 may be constituted by the lower surface 472a of the lower protruding portion 472 of the lower intervening wall 47 as in the embodiment, and the mounting surface of the third holding portion 5 may be constituted by a portion other than the lower intervening wall 57. Also, for example, in the configuration of the embodiment, a configuration may be adopted in which the lower outer walls 48, 58 of at least one of the second holding portion 4 and the third holding portion 5 extend downward D1 beyond the lower intervening walls 47, 57, and the lower surfaces of the lower outer walls 48, 58 serve as the mounting surface.

[0063] In the embodiment, the holder 2 is configured to be able to stand on the mounting member 10 by the mounting surfaces formed on each of the multiple holding parts (specifically, the second and third holding parts 5), but this is not limited to the above. In other words, the portion of the holder 2 that comes into contact with the mounting member 10 only needs to be a mounting surface formed on one of the holding parts, and the other portions do not need to be surfaces, and may be configured to come into point or line contact with the mounting member 10 by, for example, the tips of protrusions or the like.

[0064] 1 to 6, the first connecting portion 61 and the second connecting portion 62 are each shown as being elongated in one direction, but are not limited thereto. For example, at least one of the first connecting portion 61 and the second connecting portion 62 may have a shape bent in a plane perpendicular to the up-down direction D. Also, in FIG. 1 to FIG. 6, the upper arrangement grooves 31, 41, 51 and the lower arrangement grooves 32, 42, 52 of the first to third holding portions 3 to 5 are shown as being formed in the same direction, but are not limited thereto. For example, the upper arrangement groove 31 and the lower arrangement groove 32 of the first holding portion 3, the upper arrangement groove 41 and the lower arrangement groove 42 of the second holding portion 4, and the upper arrangement groove 51 and the lower arrangement groove 52 of the third holding portion 5 may be formed in different directions.

[0065] In the embodiment, the holder 2 is configured to be placed on the mounting member 10 by the mounting surface of the second holding portion 4 and the mounting surface of the third holding portion 5, but this is not limited to the above. For example, in the configuration of the embodiment, the first holding portion 3 may be formed with a mounting surface that is aligned in height with the mounting surfaces formed on the other holding portions. Also, for example, a configuration may be adopted in which a mounting surface is formed on each of the first holding portion 3 and the third holding portion 5, and the second holding portion 4 is floating when the holder 2 is placed on the mounting member 10.
