Embodiments for Carrying Out the Invention

[0009] [First Embodiment] FIG. 1(a) is an external view showing an in-vehicle wire harness 1 according to the first embodiment of the present invention. FIG. 1(b) is a cross-sectional view of the wire harness 1. The wire harness 1 has a first cable 2 and a second cable 3 as a plurality of cables, and connects an in-vehicle device disposed under the spring of the vehicle and a control device on the vehicle body side by the first cable 2 and the second cable 3.

[0010] The wire harness 1 also includes a sheath 4 that covers a portion of the longitudinal direction of the first cable 2 and the second cable 3 together, a resin molded member 5 provided at the end of the sheath 4, a mounting member 6 attached to the resin molded member 5, a metal bracket 7 fixed to the resin molded member 5, and a tube 8 with one end covered by the resin molded member 5. The tube 8 is, for example, a hollow tubular shape and may have a gap between it and the second cable 3 outside the resin molded member 5. Alternatively, the tube 8 may be an adhesive-backed heat-shrinkable tube with adhesive on its inner surface and may be adhesively fixed to the second cable 3 outside the resin molded member 5 so as not to have a gap.

[0011] Figures 2(a), (b), and (c) are cross-sectional views of lines AA, BB, and CC in Figure 1(a). The sheath 4 covers the first cable 2 and the second cable 3 together. The first cable 2 and the second cable 3 are twisted together inside the sheath 4 and are led out from the end of the sheath 4 inside the resin molded member 5. Figure 1(b) shows cross-sections of the resin molded member 5 and the mounting member 6, as well as the first cable 2 and the second cable 3 inside the resin molded member 5. The sheath 4 may be a hollow tubular shape (hollow structure) as shown in Figure 2(a), or an intervening material may be further provided in this hollow portion. Alternatively, the sheath 4 may be a solid tubular shape (solid structure).

[0012] The first cable 2 has a pair of twisted insulated wires 21, 21 and an outer sheath 22 covering the pair of insulated wires 21, 21. Each insulated wire 21 has a conductor wire 211 made of multiple strands twisted together, for example, made of a copper alloy, and an insulator 212 made of a resin such as polyethylene that covers the conductor wire 211.

[0013] The second cable 3 consists of a pair of twisted insulated wires 31, 31. Each insulated wire 31 has a conductor wire 311 made of multiple strands twisted together, for example, made of a copper alloy, and an insulator 312 made of a resin such as polyethylene that covers the conductor wire 311. The insulated wire 21 of the first cable 2 is formed to be thinner than the insulated wire 31 of the second cable 3. Also, the first cable 2 is formed to be thinner than the insulated wire 31 of the second cable 3. The tube 8 covers a portion of the second cable 3 in the longitudinal direction, both inside and outside the resin molded member 5.

[0014] The resin molded member 5 is a resin molded body molded to cover one longitudinal end of the sheath 4 and the tube 8, the first cable 2 led out from the sheath 4, and the second cable 3 between the sheath 4 and the tube 8. The resin molded member 5, the sheath 4, the tube 8, and the outer sheath 22 of the first cable 2 are made of the same type of resin. This provides high compatibility between the sheath 4, the tube 8, the outer sheath 22 of the first cable 2 and the resin molded member 5, thereby improving waterproofing. In other words, the heat generated during the molding of the resin molded member 5 causes the sheath 4, the tube 8, and the outer sheath 22 of the first cable 2 to melt together with the resin molded member 5, preventing moisture from entering through the gaps between these components. In this embodiment, the resin molded member 5, the sheath 4, the tube 8, and the outer sheath 22 of the first cable 2 are made of urethane resin.

[0015] In this embodiment, both the first cable 2 and the second cable 3 are led out from one of the outlet planes 5a of the resin molded member 5, but the outlet direction of the first cable 2 is inclined with respect to the outlet direction of the second cable 3. As shown in Figure 1(a), when the outlet direction of the first cable 2 from the resin molded member 5 is D1, and the outlet directions of the second cable 3 and tube 8 from the resin molded member 5 are D2, the angle θ between D1 and D2 is greater than 0° and 45° or less. In the example shown in Figure 1(a), the angle θ is 10°.

[0016] Because the exit direction D1 of the first cable 2 is inclined with respect to the exit direction D2 of the second cable 3, the resin of the resin molded member 5 can easily penetrate between the first cable 2 and the second cable 3, or more specifically, between the tube 8 covering the first cable 2 and the second cable 3, thereby enhancing the waterproofness that prevents moisture from entering the inside of the resin molded member 5.

[0017] As shown in Figure 1(b), the resin molded member 5 integrally comprises a main body 51 having a sheath holding portion 511 that covers the outer circumference of the ends of the sheath 4 from which the first cable 2 and the second cable 3 are led out and holds the sheath 4, a cable holding portion 512 that holds the portions of the first cable 2 and the second cable 3 led out from the sheath 4, and a tube holding portion 513 that covers the outer circumference of the end of the tube 8 and holds the tube 8, and a bracket fixing portion 52 to which the bracket 7 is fixed. In this embodiment, the bracket fixing portion 52 is formed in a cylindrical shape. The bracket 7 has a flat plate portion 71 with a bolt insertion hole 70 formed therein and a winding portion 72 that is wrapped around the bracket fixing portion 52 of the resin molded member 5. The configuration of the sheath holding portion 511, the cable holding portion 512, and the tube holding portion 513 in the main body 51 is the same in other embodiments and modifications described later.

[0018] Hereinafter, the resin molded member 5, and the first cable 2, second cable 3, sheath 4, and tube 8 molded onto the resin molded member 5 and integrated with the resin molded member 5, will be referred to as the harness body 10.

[0019] The mounting member 6 is a resin molded body injection-molded separately from the resin molded member 5. The resin material of the mounting member 6 may be the same urethane resin as that of the resin molded member 5, but is not limited to this; for example, nylon may also be used. The mounting member 6 has a holding portion 61 for holding the first cable 2 and guides the first cable 2 in a different direction from the second cable 3. The second cable 3 is not guided by the mounting member 6 and extends along the direction of exit from the resin molded member 5 in the vicinity of the resin molded member 5.

[0020] Since the first cable 2 is thinner than the insulated wire 31 of the second cable 3 and is easier to bend than the second cable 3, by holding and guiding the first cable 2 with the holding part 61 that holds the first cable 2, it can be bent with a smaller radius of curvature than the second cable 3, and the wire harness 1 can be made smaller.

[0021] However, depending on the application and function of the wire harness 1, the tube 8 may be held by the holding portion 61 of the mounting member 6 to guide the second cable 3 in a different direction from the first cable 2. In this case, the first cable 2 is not guided by the mounting member 6 and extends along the exit direction from the resin molded member 5 in the vicinity of the resin molded member 5.

[0022] The retaining portion 61 is provided in a portion that protrudes from the lead-out plane 5a of the resin molded member 5, along the lead-out direction of the first cable 2 and the second cable 3 from the lead-out plane 5a, when the mounting member 6 is mounted on the resin molded member 5. This prevents the curvature of the first cable 2 between the lead-out plane 5a and the retaining portion 61 from becoming excessive. Next, the mounting structure of the resin molded member 5 and the mounting member 6 in this embodiment will be described in detail.

[0023] Figure 3(a) is a perspective view showing the mounting member 6 and the harness body 10. Figure 3(b) is a perspective view showing the mounting member 6 attached to the resin molded member 5. Figure 3(c) is a perspective view showing the first cable 2 held in the holding portion 61 of the mounting member 6. Figure 4 is a four-view drawing of the harness body 10. Figure 5 is a four-view drawing of the mounting member 6. Note that Figure 3(c) shows the side view of the resin molded member 5 and mounting member 6 on the opposite side from Figures 3(a) and (b).

[0024] The resin molded member 5 and the mounting member 6 are attached by an engaging projection provided on one member engaging with an engaging recess provided on the other member. In this embodiment, the mounting member 6 is attached to the resin molded member 5 by a plurality of engaging projections 60 provided on the mounting member 6 engaging with a plurality of engaging recesses 510 provided on the main body portion 51 of the resin molded member 5.

[0025] The main body 51 of the resin molded member 5 is rectangular in shape, and the mating surface 51a with the mounting member 6 is a flat rectangle. The main body 51 has two engaging recesses 510 arranged in the long direction at both ends of the short side of the mating surface 51a. In addition, two engaging recesses 510 are open on a pair of sides 51b and 51c of the main body 51, which are arranged in the short side of the mating surface 51a. As shown in an enlarged view in Figure 4, the engaging recess 510 has an enlarged portion 510a and a groove portion 510b formed linearly between the enlarged portion 510a and the mating surface 51a. The maximum width W of the enlarged portion 510a in the long direction of the mating surface 51a 11 The width W of the groove portion 510b in the same direction. 12 It is formed to be larger than that.

[0026] The mounting member 6 has a flat rectangular mating surface 6a facing the mating surface 51a of the resin molded member 5, and two engaging protrusions 60 are provided side by side in the long direction at both ends of the short side of the mating surface 6a. The engaging protrusions 60 are provided so as to extend in a direction perpendicular to the mating surface 6a and have a disc-shaped large diameter portion 601 and a column portion 602 between the large diameter portion 601 and the mating surface 6a. The maximum width W of the large diameter portion 601 in the long direction of the mating surface 6a 21 The width W of the column portion 602 in the same direction. 22 It is formed to be larger than the other. The mounting member 6 has four engaging protrusions 60, which provide an anti-detachment effect in the front-to-back, left-to-right, and up-and-down directions.

[0027] When combining the resin molded member 5 and the mounting member 6, the mating surface 51a of the resin molded member 5 and the mating surface 6a of the mounting member 6 are faced to each other, and the mating surfaces 51a and 6a are brought close to each other so that the plurality of engaging protrusions 60 of the mounting member 6 are respectively fitted into the plurality of engaging recesses 510 of the resin molded member 5. In a state where the engaging protrusion 60 is fitted into the engaging recess 510, the large-diameter portion 601 of the engaging protrusion 60 is accommodated in the enlarged portion 510a of the engaging recess 510, and the column portion 602 of the engaging protrusion 60 is accommodated in the concave groove portion 510b of the engaging recess 510.

[0028] The maximum width W of the large-diameter portion 601 of the engaging protrusion 60 21 is the size corresponding to the maximum width W of the enlarged portion 510a of the engaging recess 510, and the width W of the column portion 602 of the engaging protrusion 60 11 is the size corresponding to the width W of the concave groove portion 510b of the engaging recess 510. Also, the maximum width W of the large-diameter portion 601 of the engaging protrusion 60 21 is the width W of the concave groove portion 510b of the engaging recess 510 12 12 is larger than. Thereby, the engaging protrusion 60 is prevented from coming out of the engaging recess 510, and the mounting member 6 is prevented from detaching from the resin molded member 5. When the large-diameter portion 601 passes through the concave groove portion 510b, the main body portion 51 of the resin molded member 5 and the engaging protrusion 60 of the mounting member 6 are elastically deformed.

[0029] In the holding portion 61 of the mounting member 6, a holding groove 610 is formed that is parallel to the leading-out plane 5a of the resin molded member 5 and extends in a direction perpendicular to the mating surface 6a of the mounting member 6. The holding groove 610 has a C-shaped cross-sectional shape when viewed along its extending direction and opens to the front end surface 61a of the holding portion 61. In the present embodiment, the front end surface 61a of the holding portion 61 is a plane parallel to the leading-out plane 5a of the resin molded member 5.

[0030] When holding the first cable 2 in the holding portion 61, the first cable 2 is pushed into the holding groove 610 from the opening of the holding groove 610 at the front end surface 61a. As shown in FIG. 5, the maximum width W of the holding groove 610 in a direction parallel to the front end surface 61a 31 ​​​This refers to the minimum width W of the portion through which the first cable 2 passes when the first cable 2 is held by the holding part 61. 32 It is wider than that. Also, the minimum width W 32 This is narrower than the outer diameter of the first cable 2. This prevents the first cable 2 from slipping out of the retaining groove 610.

[0031] When assembling the wire harness 1, a resin molded member 5 is formed using a mold to create the harness body 10, and then a pre-molded mounting member 6 is attached to the resin molded member 5. After that, the first cable 2 led out from the resin molded member 5 is held in the holding portion 61 of the mounting member 6.

[0032] Figures 6(a) and 6(b) are explanatory diagrams showing the molds (lower molds) 101 and 102 for forming the harness body 10 by molding the resin molded member 5, along with a plurality of harness bodies 10 having the molded resin molded member 5. The resin molded member 5 has a plurality of engaging recesses 510 that are open to the sides 51b and 51c of the main body portion 51, so it can be molded using upper and lower molds without using a sliding mold. Also, Figures 6(a) and 6(b) show the sprues 103 and 104 and runners 105 and 106 that are formed by the flow of resin. The molten resin is injected into the cavity from the portion that will become the mating surface 51a in the resin molded member 5 to be molded.

[0033] In the mold 101 shown in Figure 6(a), resin molded members 5 of two harness bodies 10 are formed. The first cable 2, the second cable 3, the sheath 4, and the tube 8 are arranged in the mold 101 so that the sheaths 4 of the two harness bodies 10 are parallel to each other.

[0034] In the mold 102 shown in Figure 6(b), resin molded members 5 of the four harness bodies 10 are formed. The first cable 2, second cable 3, sheath 4, and tube 8 of the four harness bodies 10 are arranged in the mold 102 so that their respective sheaths 4 and tubes 8 cross each other. At the point where the first cable 2, second cable 3, sheath 4, and tube 8 cross, these members are held in either the upper or lower mold.

[0035] Figure 7 is an explanatory diagram showing a mold (lower mold) 107 relating to a comparative example, and two harness bodies 100 having a resin molded member 50 formed by this mold 107. Figure 7 also shows a sprue 108 and a runner 109 formed by the flow of resin for molding the resin molded member 50. The harness body 100 has a first cable 2, a second cable 3, a sheath 4, and a tube 8, similar to the harness body 10 of this embodiment, but the direction in which the first cable 2 is led out from the resin molded member 50 is different from that of the harness body 10, with the first cable 2 being led out at a right angle to the second cable 3.

[0036] Comparing the mold 101 shown in Figure 6(a) with the mold 107 of the comparative example, in mold 101, the first cable 2 and the second cable 3 are led out from the exit plane 5a of the resin mold member 5, so the width of the mold 101 in the direction perpendicular to the second cable 3, sheath 4, and tube 8 can be narrowed. As a result, mold 101 can be made smaller than mold 107 of the comparative example, and mold costs can be reduced. Furthermore, in mold 102 shown in Figure 6(b), the resin mold members 5 of the four harness bodies 10 can be molded simultaneously, improving production efficiency.

[0037] Figure 8 is an explanatory diagram showing an example of the use of the wire harness 1 according to this embodiment when mounted on a vehicle. Figure 8 shows a wheel 90, a hub unit 91 that rotatably supports the wheel 90, a knuckle 92 of the suspension system to which the hub unit 91 is attached, a damping force variable damper 93 connected to the knuckle 92, a suspension spring 94, an electric parking brake device 95, a wheel speed sensor 96 that detects the rotational speed of the wheel 90, and a brake disc 97 that rotates with the wheel 90. The tube 8 protects the second cable 3 from damage caused by flying stones, etc.

[0038] The hub unit 91 has a hub wheel 911 that rotates integrally with the wheel 90, an outer wheel 912 fixed to the knuckle 92, and a plurality of rolling elements 913 positioned between the hub wheel 911 and the outer wheel 912. An annular magnetic encoder 98 having a plurality of magnetic poles along the circumferential direction is fixed to the hub wheel 911, facing a wheel speed sensor 96. The wheel speed sensor 96 is fixed to the outer wheel 912 and detects the rotational speed of the wheel 90 by the rotation of the magnetic encoder 98.

[0039] The bracket 7 of the wire harness 1 is fastened to the knuckle 92 by bolts 99, thereby fixing the resin molded member 5 to the knuckle 92. A connector 20 for connection to the wheel speed sensor 96 is attached to the tip of the first cable 2. A connector 30 for connection to the connector 951 on the electric parking brake device 95 side is attached to the tip of the second cable 3. In other words, in this embodiment, the first cable 2 is a wheel speed signal cable that is connected to the wheel speed sensor 96 and transmits a wheel speed detection signal.

[0040] As shown in Figure 8, the position of the wheel speed sensor 96 and the position of the electric parking brake device 95 as seen from the resin molded member 5 are significantly different. However, because the first cable 2 is guided toward the position of the wheel speed sensor 96 by the mounting member 6, the first cable 2 is connected to the wheel speed sensor 96 without bending significantly beyond the mounting member 6 at its tip. This prevents the outer sheath 22 of the first cable 2 from being worn down by contact with, for example, the outer ring 912 of the hub unit 91 or the brake disc 97.

[0041] Figures 9(a) and 9(b) are perspective views showing configuration examples of mounting members 6A and 6B with different shapes of retaining portion 61. Like the mounting member 6 described above, mounting members 6A and 6B have multiple engaging protrusions 60 and are attached to the resin molded member 5. The angle of the retaining groove 610 of mounting members 6A and 6B differs from that of mounting member 6 described above, so when mounting members 6A and 6B are used, the first cable 2 can be guided in a different direction than when mounting member 6 is used. As a result, even if the vehicle configuration changes, the first cable 2 can be guided toward its connection destination without changing the shape of the resin molded member 5. In other words, the harness body 10 can be shared across many vehicle models without changing the configuration of the harness body 10.

[0042] Furthermore, since the mounting members 6, 6A, and 6B are smaller than the harness body 10, the mold for molding the mounting members 6, 6A, and 6B will be smaller than, for example, the mold 101 shown in Figure 6(a). In addition, it is easy to configure the mold for multiple cavities and simultaneously mold a large number of mounting members 6, 6A, and 6B in a single injection molding.

[0043] (Effects of the first embodiment) According to the first embodiment described above, since the resin molded member 5 and the mounting member 6 are separate components, even if the vehicle configuration changes, it is possible to accommodate this change simply by modifying the shape of the mounting member 6. This makes it possible to standardize the resin molded member 5 and the harness body 10 equipped with it, thereby reducing the cost of molds for molding the resin molded member 5 and lowering manufacturing costs.

[0044] [Modified version of the first embodiment] Figures 10(a) to 10(c) are perspective views showing a modified mounting member 6C according to the first embodiment, together with the harness body 10 to which the mounting member 6C is combined. In the first embodiment described above, the case in which the mounting member 6 has one holding portion 61 was explained, but the mounting member 6C according to this modified embodiment is provided with an additional holding portion 62 in addition to the holding portion 61 similar to that of the mounting member 6. Figure 10(b) shows the mounting member 6C attached to the resin molded member 5, and Figure 10(c) shows the first cable 2 being held by the holding portion 62 of the mounting member 6C.

[0045] A retaining groove 620 for holding the first cable 2 is formed in the retaining portion 62 of the mounting member 6C. The retaining groove 620 extends in a direction inclined with respect to the lead plane 5a of the resin molded member 5 and opens to the side surface 6b of the mounting member 6C. When the first cable 2 is held in the retaining portion 62 of the mounting member 6C, the first cable 2 is guided in a different direction than when the first cable 2 is held in the retaining portion 61 of the mounting member 6C. Thus, the mounting member 6C is provided with multiple retaining portions 61 and 62, and the guiding direction of the first cable 2 by these multiple retaining portions 61 and 62 is different for each.

[0046] According to this modified version, in addition to the effects of the first embodiment, the mounting member 6C has multiple holding parts 61 and 62, so that the first cable 2 can be guided in multiple different directions depending on the vehicle configuration. In other words, the direction in which the first cable 2 is guided can be changed by whether the first cable 2 is held by the holding part 61 or the holding part 62 of the mounting member 6C, making it possible to share the mounting member 6C among multiple vehicle models with different vehicle configurations, and thus reducing the increase in mold costs for molding the mounting member 6C.

[0047] Alternatively, the harness body 10 may be configured to include a third cable in addition to the first cable 2 and the second cable 3, with the first cable 2 being guided by the holding portion 61 of the mounting member 6C and the third cable being guided by the holding portion 62. In this case, the third cable may be connected to, for example, a redundant wheel speed sensor or a wheel vertical acceleration sensor that detects the vertical movement of the wheel. The third cable may also be connected to the variable damping force damper 93.

[0048] [Second Embodiment] Next, a second embodiment of the present invention will be described. In the first embodiment, the mounting member 6 is fixed to the resin molded member 5 by the engagement of a plurality of engaging protrusions 60 of the mounting member 6 with a plurality of engaging recesses 510 of the resin molded member 5. In the second embodiment, however, the mounting member is pivotable relative to the resin molded member.

[0049] Figure 11(a) is a perspective view showing a harness body 10D having a mounting member 6D according to this embodiment and a resin molded member 5D to which the mounting member 6D is pivotably mounted. Figure 11(b) is a perspective view showing the mounting member 6D mounted on the resin molded member 5D. Figure 11(c) is a perspective view showing the first cable 2 held in the holding portion 61 of the mounting member 6D. Figure 11(c) shows the side view of the resin molded member 5D and mounting member 6D opposite to that shown in Figures 11(a) and (b).

[0050] Figure 12(a) is an explanatory diagram showing the state in which the surface 6c of the mounting member 6D facing the resin molded member 5D and the surface 5b of the resin molded member 5D facing the mounting member 6D are parallel. Figure 12(b) is an explanatory diagram showing the state in which the mounting member 6D is oscillating relative to the resin molded member 5D. As shown in Figure 12(a), when the opposing surfaces 6c and 5b of the mounting member 6D and the resin molded member 5D are parallel, a space is formed between these opposing surfaces 6c and 5b. The opposing surfaces 6c and 5b are rectangular in shape, with the direction along the longitudinal direction of the sheath 4 and the tube 8 being the longer side.

[0051] The harness body 10D, like the harness body 10 according to the first embodiment, has a first cable 2, a second cable 3, a sheath 4, and a tube 8, with the first cable 2 and the second cable 3 being led out from the sheath 4 inside the resin molded member 5D. The direction in which the first cable 2 and the second cable 3 are led out from the resin molded member 5D is also the same as that of the harness body 10 according to the first embodiment.

[0052] The mounting member 6D has a pair of swing arms 63 that protrude toward the resin mold member 5D from the surface 6c of the mounting member 6D facing the resin mold member 5D. Each swing arm 63 has a disc-shaped disc portion 631 at its tip and a column portion 632 between the opposing surface 6c and the disc portion 631. The mounting member 6D also has a holding portion 61 similar to that of the mounting member 6 according to the first embodiment.

[0053] The resin molded member 5D is provided with a pair of recesses 53, each having an engagement hole 531 into which the disc portion 631 of the oscillating arm 63 engages, and a notch 532 that accommodates the column portion 632 of the oscillating arm 63. The engagement hole 531 and the notch 532 are in communication, and the width W4 (see Figure 11(a)) of the end of the engagement hole 531 on the notch 532 side is narrower than the diameter of the disc portion 631. This prevents the disc portion 631 from coming out of the engagement hole 531. When the mounting member 6D is attached to the resin molded member 5D, the main body portion 51 and the disc portion 631 of the resin molded member 5D undergo elastic deformation.

[0054] The pair of recesses 53 are formed in the resin molded member 5D from the surface 5b facing the mounting member 6D, with engagement holes 531 and notches 532 arranged side by side in a direction perpendicular to the opposing surface 5b. One recess 53 is open to one side surface 51b of the main body portion 51 of the resin molded member 5D, and the other recess 53 is open to the other side surface 51c of the main body portion 51 of the resin molded member 5D.

[0055] The mounting member 6D is able to pivot relative to the resin molded member 5D around the disc portion 631 of the swing arm 63 while holding the first cable 2 in the holding portion 61. As a result, even when the connection point of the first cable 2 moves relative to the member to which the resin molded member 5D is fixed, the stress on the first cable 2 is alleviated by the pivoting of the mounting member 6D.

[0056] Figure 13(a) is a perspective view showing a modified mounting member 6E in which the shape of the holding portion 61 of the mounting member 6D has been modified. Figure 13(b) is a configuration diagram showing the shape of the holding groove 640 of the holding portion 64 that holds the first cable 2 in the mounting member 6E. The mounting member 6E has a pair of swing arms 63, similar to the mounting member 6D, and is mounted on the resin molded member 5D and is swingable relative to the resin molded member 5D.

[0057] The mounting member 6E has a rectangular retaining groove 640 in the retaining portion 64 that holds the first cable 2, and the width W of the retaining groove 640 is in the direction along the long side of the opposing surface 6c. 51 , and the width W of the retaining groove 640 in the direction along the short side direction of the opposing surface 6c 52 However, it is formed to be larger than the outer diameter of the first cable 2. In addition, the retaining portion 64 of the mounting member 6E is provided with a pair of wall portions 641 to prevent the first cable 2 from slipping out of the retaining groove 640. The width W between the pair of wall portions 641 53 The retaining groove 640 is formed to be narrower than the outer diameter of the first cable 2. When the first cable 2 is housed in the retaining groove 640, the pair of wall portions 641 are elastically deformed, and the first cable 2 is pushed into the retaining groove 640 from between the pair of wall portions 641.

[0058] According to this modified version, the first cable 2 is movable longitudinally relative to the mounting member 6E while being housed in the retaining groove 640, so the stress on the first cable 2 when the mounting member 6E swings relative to the resin molded member 5D is further reduced.

[0059] [Third Embodiment] Next, a third embodiment of the present invention will be described. In this embodiment as well as in the second embodiment, the mounting member is pivotable relative to the resin molded member, but its mounting structure differs from that of the second embodiment.

[0060] Figure 14(a) is a perspective view showing a harness body 10F having a mounting member 6F according to this embodiment and a resin molded member 5F to which the mounting member 6F is pivotably mounted. Figure 14(b) is a perspective view showing the mounting member 6F mounted on the resin molded member 5F. Figure 14(c) is a perspective view showing the first cable 2 held in the holding portion 64 of the mounting member 6F. Figure 14(c) shows the side view of the resin molded member 5F and mounting member 6F on the opposite side from Figures 14(a) and (b).

[0061] Figure 15(a) is an explanatory diagram showing the state in which the surface 6d of the mounting member 6F facing the resin molded member 5F and the surface 5c of the resin molded member 5F facing the mounting member 6F are parallel. Figure 15(b) is an explanatory diagram showing the state in which the mounting member 6F is oscillating relative to the resin molded member 5F. When the opposing surfaces 6d and 5c of the mounting member 6F and the resin molded member 5F are parallel, a space is formed between these opposing surfaces 6d and 5c. The opposing surfaces 6d and 5c are rectangular in shape, with the direction along the longitudinal direction of the sheath 4 and the tube 8 being the longer side direction.

[0062] The mounting member 6F has a holding portion 64 as described with reference to Figures 13(a) and (b), and a pair of cylindrical shaft portions 65 that protrude from both sides 6e and 6f. The resin molded member 5F has a pair of support protrusions 54 that protrude from the opposing surface 5c toward the mounting member 6F and support the pair of shaft portions 65 of the mounting member 6F. The support protrusions 54 have holding holes 540 formed therein to hold the shaft portions 65 of the mounting member 6F. The holding holes 540 open in a direction perpendicular to the opposing surface 5c, and their opening width W 61 (See Figure 15(a)) The diameter is narrower than the diameter of the shaft portion 65. When attaching the mounting member 6F to the resin molded member 5F, the support projection 54 is elastically deformed to widen the opening of the retaining hole 540, and the shaft portion 65 is pushed into the retaining hole 540.

[0063] This third embodiment also provides the same effects as the second embodiment.

[0064] [Fourth Embodiment] Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, the angle of the mounting member relative to the resin mold member can be adjusted in multiple stages.

[0065] Figure 16 is a four-view drawing of the mounting member 6G according to this embodiment. Figures 17(a) and (b) are side views showing the state in which the mounting member 6G is attached to the resin molded member 5G of the harness body 10G. The angle of the mounting member 6G relative to the resin molded member 5G is different in the state shown in Figure 17(a) and the state shown in Figure 17(b).

[0066] As shown in Figure 16, the mounting member 6G has a pair of arms 66 that protrude toward the resin molded member 5G from the surface 6g of the mounting member 6G facing the resin molded member 5G. Each arm 66 has a polygonal supported portion 661 at its tip and a columnar portion 662 between the opposing surface 6g and the supported portion 661. The columnar portion 662 of each of the pair of arms 66 extends along the sides 6h and 6i of the mounting member 6G in a direction perpendicular to the opposing surface 6g. The supported portion 661 of one arm 66 is provided to protrude from one side 6h of the mounting member 6G, and the supported portion 661 of the other arm 66 is provided to protrude from the other side 6i of the mounting member 6G. In this embodiment, the supported portion 661, when viewed from a direction perpendicular to the sides 6h and 6i, is hexagonal. However, the shape of the supported portion 661 does not have to be circular; it may be an n-sided polygon (where n is a natural number of 3 or more) or an ellipse.

[0067] Furthermore, the mounting member 6D has a retaining portion 67 similar to that of the mounting member 6 according to the first embodiment. The retaining portion 67 has a retaining groove 670 for accommodating the second cable 3.

[0068] The resin molded member 5G has a pair of support protrusions 55 that project toward the mounting member 6G from the opposing surface 5d facing the opposing surface 6g of the mounting member 6G, and support the respective supported portions 661 of the pair of arms 66 of the mounting member 6G. Figures 17(a) and (b) show one of the support protrusions 55. The support protrusion 55 has a retaining hole 550 formed in a shape corresponding to the supported portion 661. The retaining hole 550 opens in a direction perpendicular to the opposing surface 5d, and its opening width W 62 (See Figure 17(a)) The support portion is formed to be smaller than the size of the supported portion 661. This prevents the supported portion 661 from coming out of the retaining hole 550.

[0069] When attaching the mounting member 6G to the resin molded member 5G, the support projection 55 may be elastically deformed to widen the opening of the holding hole 550, or the pair of arms 66 may be elastically deformed so that the supported portions 661 of the pair of arms 66 come closer together, and the supported portions 661 may be fitted into the holding hole 550 from between the pair of support projections 55. Forming the resin molded member 5G and the mounting member 6G from urethane makes such elastic deformation easier.

[0070] As shown in Figures 17(a) and (b), in this embodiment, the mounting member 6G can be fixed to the resin molded member 5G at multiple different angles, and the guiding direction of the second cable 3 by the mounting member 6G is variable according to this angle. In other words, the guiding direction of the second cable 3 can be selected by the angle of the mounting member 6G relative to the resin molded member 5G. This makes it possible to share the resin molded member 5G and the mounting member 6G in multiple vehicle models with different vehicle configurations, and reduces the increase in mold costs for molding the resin molded member 5G and the mounting member 6G.
