DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

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

[0011] (1) An electric wire cover for holding a bent portion of an electric wire, comprising: an inner cover body covering the bent portion from an inner circumferential side; an inner cover member including an inner cover body having a first inner mounting portion provided at one end of the inner cover body and a second inner mounting portion provided at the other end of the inner cover body; and an outer cover body covering the bent portion from an outer circumferential side; and an outer cover member including a first outer mounting portion provided at one end of the outer cover body and a second outer mounting portion provided at the other end of the outer cover body, wherein the inner cover member and the outer cover member are fixed together by mounting a first mounting portion between the first inner mounting portion and the first outer mounting portion and mounting a second mounting portion between the second inner mounting portion and the second outer mounting portion. The wire cover is configured such that the one end of the inner cover body and the one end of the outer cover body sandwich the electric wire along a first direction, the other end of the inner cover body and the other end of the outer cover body sandwich the electric wire along a second direction intersecting the first direction, the first attachment portion and the second attachment portion are located outside the innermost surface of the inner cover body or inside the outermost surface of the outer cover body when observed from a third direction intersecting a plane including the first direction and the second direction, and the inner cover member and the outer cover member move relatively along the first direction to attach the first attachment portion and the second attachment portion, respectively. In the wire cover that holds the bent portion of the electric wire, the first attachment portion and the second attachment portion are provided so as to avoid the inside and outside of the bent portion. Therefore, a space can be secured at least on either the inside or the outside of the bent portion.

[0012] (2) In the wire cover of (1), at the one end including the first attachment portion, the inner cover member and the outer cover member may be engaged in any one of the first direction, the second direction, and the third direction, and at the other end including the second attachment portion, the inner cover member and the outer cover member may overlap in the second direction and the third direction and be engaged in the second direction and the third direction among the first direction, the second direction, and the third direction. This makes it easy to fix the inner cover member and the outer cover member by the first attachment portion and the second attachment portion.

[0013] (3) In the wire cover of (2), the inner cover member and the outer cover member may be overlapped in three or more layers along each of the second direction and the third direction at the other end including the second attachment portion, thereby making it difficult for the second attachment portion to open in the second direction and the third direction.

[0014] (4) In the wire cover of (3), the inner cover member and the outer cover member may be overlapped in four or more layers along each of the second direction and the third direction at the other end including the second attachment portion, making it more difficult for the second attachment portion to open in the second direction and the third direction.

[0015] (5) In the wire cover according to any one of (1) to (4), the inner cover body and the outer cover body may be provided with a mounting portion at one end or the other end, the mounting portion being fitted into a rear end of a connector, so that the wire cover can be mounted on the connector and hold a bent portion of the wire extending from the connector.

[0016] (6) In the wire cover of any one of (2) to (4), the inner cover body and the outer cover body may be provided at the one end with an attachment portion that fits into the rear end of the connector, the attachment portion having an inner groove formed on the inner surface of the inner cover body and an outer groove formed on the inner surface of the outer cover body, and a flange portion of the rear end of the connector may fit into the inner groove and the outer groove. In this way, the flange portion of the connector rear end fits into the inner groove and the outer groove, and a attachment portion can be provided at one end where a lock portion is provided, making it easier to stably attach the connector to the rear end.

[0017] (7) In the wire cover according to any one of (1) to (6), the inner cover body and the outer cover body may be provided at the other end with a cylindrical member attachment portion that overlaps with a cylindrical member, whereby a cylindrical member such as a rubber hose can be attached to the wire cover.

[0018] (8) In the wire cover of any one of (1) to (7), a drainage hole may be formed in at least one of the inner cover body and the outer cover body, so that water in the wire cover can be discharged to the outside of the wire cover through the drainage hole.

[0019] (9) In the wire cover of any one of (1) to (8), the inner cover member and the outer cover member may each be an injection molded product formed in a shape free of undercuts so as to be removable from the top and bottom of the mold. This simplifies the shape of the mold and prevents costs from increasing.

[0020] (10) In the wire cover of any one of (1) to (9), the first attachment portion and the second attachment portion may be located outside an innermost surface of the inner cover body and inside an outermost surface of the outer cover body when observed from the third direction, thereby making it possible to secure space both inside and outside the cover body.

[0021] (11) A wiring member according to the present disclosure includes an electric wire having a bent portion disposed along a bending path, and any one of the electric wire covers (1) to (10) attached to the bent portion. This allows the bent portion of the electric wire to be held by the electric wire cover, while ensuring space at least on either the inside or the outside of the bent portion.

[0022] [Details of the embodiment of the present disclosure] Specific examples of the wire cover 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.

[0023] [Embodiment 1] Hereinafter, the electric wire cover according to the first embodiment and the wiring member including the same will be described. Fig. 1 is a perspective view showing the electric wire cover 50 according to the first embodiment and the wiring member 10 including the same. Fig. 2 is a side view showing the wiring member 10. Fig. 3 is an exploded perspective view showing the wiring member 10. Fig. 1 shows an X direction, a Y direction, and a Z direction as three directions perpendicular to each other. The X direction, the Y direction, and the Z direction in each of Figs. 2 and thereafter correspond to the X direction, the Y direction, and the Z direction in Fig. 1.

[0024] <Wiring materials> The wiring member 10 includes an electric wire 20 and an electric wire cover 50. It is assumed that the wiring member 10 will be disposed along a curved path in a vehicle or the like. For this reason, the electric wire 20 includes a bent portion 12 disposed along the bending path. The electric wire cover 50 is attached to the bent portion 12. The bent portion 12 is held in a bent state by the electric wire cover 50. The shape into which the wiring member 10 is bent is determined by the positional relationship of the portion to which the end of the wiring member 10 is attached, the layout of any interfering objects in the portion where the wiring member 10 is disposed, and the like.

[0025] At least one electric wire 20 is provided. For example, the electric wire 20 is a covered electric wire having a core wire and a covering layer. For example, the core wire is a stranded wire in which a plurality of elemental wires are twisted together. Each elemental wire may be made of a metal such as copper or aluminum. For example, the covering layer is formed by extruding a resin around the core wire. The resin may be polyethylene, polyvinyl chloride, or the like. The electric wire 20 may be a cable in which a plurality of electric wires are covered with a sheath.

[0026] The wiring member 10 may be disposed at any position in the vehicle. For example, one end of the wiring member 10 may be connected to a device disposed in the vehicle's undercarriage. The electric wire 20 may be used as a power line or a signal line. For example, the electric wire 20 may be a power line that supplies power to an EPB (Electric Parking Brake) or an EMB (Electro-Mechanical Brake). In addition, for example, the electric wire 20 may be a signal line that transmits a signal from a sensor for detecting the wheel speed in an ABS (Anti-Lock Brake System).

[0027] A connector 30 is provided at an end of the electric wire 20. The connector 30 is connected to a mating connector provided on an apparatus or the like. The connector 30 includes a connector housing and a connector terminal. A core wire of the electric wire 20 is connected to the connector terminal. The electric wire 20 and the apparatus are connected via the connector 30. In this example, it is described that a bent portion 12 is provided on a portion of the electric wire 20 extending from the connector 30. In this example, a flange portion 32 is provided at the rear end of the connector 30. The flange portion 32 protrudes around the main body of the connector housing.

[0028] A cylindrical member 40 is provided at the middle of the electric wire 20. Here, the cylindrical member 40 is provided at a position away from the connector 30 along the extending direction of the electric wire 20. Here, the cylindrical member 40 is provided on the opposite side of the bent portion 12 of the electric wire 20 from the connector 30 side. Here, the cylindrical member 40 is provided at a portion after the electric wire 20 extending from the connector 30 is bent through the bent portion 12. The electric wire 20 penetrates the cylindrical member 40. One end of the cylindrical member 40 is attached to the electric wire cover 50. The cylindrical member 40 of this example is continuous with the same outer diameter along the axial direction. Such a cylindrical member 40 is, for example, a rubber tube. The cylindrical member 40 may be configured such that the outer diameter alternates along the axial direction, such as a corrugated tube.

[0029] <Wire cover> The wire cover 50 will be described with further reference to Figs. 4 to 9. Figs. 4 and 5 are exploded perspective views of the wire cover 50. Figs. 4 and 5 are views seen from different viewpoints. Fig. 6 is an exploded side view of the wire cover 50. Fig. 7 is an exploded front view of the wire cover 50. Fig. 8 is an exploded plan view of the wire cover 50. Fig. 9 is an exploded bottom view of the wire cover 50.

[0030] The wire cover 50 holds the bent portion 12 of the wire 20. The wire cover 50 is provided with a cover body 51, a first attachment portion 52, and a second attachment portion . The wire cover 50 includes an inner cover member 60 and an outer cover member .

[0031] The inner cover member 60 includes an inner cover main body 61, a first inner mounting portion 62, and a second inner mounting portion 64. The inner cover main body 61 covers the bent portion 12 from the inner circumferential side. The first inner mounting portion 62 is provided at one end of the inner cover main body 61. The second inner mounting portion 64 is provided at the other end of the inner cover main body 61.

[0032] The outer cover member 70 includes an outer cover main body 71, a first outer mounting portion 72, and a second outer mounting portion 74. The outer cover main body 71 covers the bent portion 12 from the outer periphery side. The first outer mounting portion 72 is provided at one end of the outer cover main body 71. The second outer mounting portion 74 is provided at the other end of the outer cover main body 71.

[0033] The inner cover body 61 and the outer cover body 71 form the cover body 51 that covers the bent portion 12. The first inner mounting portion 62 and the first outer mounting portion 72 form the first mounting portion 52. The second inner mounting portion 64 and the second outer mounting portion 74 form the second mounting portion 54. The inner cover member 60 and the outer cover member 70 are fixed to each other by attaching the first mounting portion 52 and the second mounting portion 54 to form the wire cover 50.

[0034] <Cover body> The cover body 51 will be described with further reference to Fig. 10. Fig. 10 is a cross-sectional view showing the cover body 51. Fig. 10 is a cross-sectional view taken along the line XX in Fig. 2.

[0035] The cover body 51 has an inner cover body 61 and an outer cover body 71. The inner cover body 61 has a bottom wall 61a, two side walls 61b, and a support portion 61c. The outer cover body 71 has a lid portion 71a and two side walls 71b.

[0036] The two side walls 61b protrude from both sides of the bottom wall 61a. The bottom wall 61a and the two side walls 61b form a gutter-shaped storage section. The lid section 71a covers the bottom wall 61a and the upper parts of the two side walls 61b. The two side walls 71b protrude from both sides of the lid section 71a. The two side walls 61b are positioned between the two side walls 71b. This makes it difficult for the inner cover body 61 and the outer cover body 71 to shift in the Y direction. The two side walls 71b are supported by the support section 61c. This prevents the inner cover body 61 and the outer cover body 71 from tilting to open on the other side in the Y direction with the contact part on one side of the Y direction as a fulcrum. This prevents the opening of the inner cover body 61 and the outer cover body 71.

[0037] One end of the inner cover body 61 and one end of the outer cover body 71 sandwich the electric wire 20 along a first direction. The other end of the inner cover body 61 and the other end of the outer cover body 71 sandwich the electric wire 20 along a second direction intersecting the first direction.

[0038] In this example, the electric wire 20 is bent 90 degrees via the bent portion 12. Therefore, the first direction and the second direction are perpendicular to each other. Specifically, the electric wire 20 extends in the Z direction on one side of the bent portion 12 and extends in the X direction on the other side of the bent portion 12. One end of the inner cover body 61 and one end of the outer cover body 71 sandwich the electric wire 20 along the X direction. The other end of the inner cover body 61 and the other end of the outer cover body 71 sandwich the electric wire 20 along the Z direction. In this example, the first direction is the X direction and the second direction is the Z direction.

[0039] The electric wire 20 may be bent at an angle smaller than 90 degrees through the bent portion 12, or may be bent at an angle larger than 90 degrees. For example, the electric wire 20 may extend in the Z direction on one side of the bent portion 12, and extend in a direction inclined from the X direction and the Z direction on the other side of the bent portion 12.

[0040] <First mounting part> The first mounting portion 52 will be described with further reference to Fig. 11. Fig. 11 is a cross-sectional view showing the first mounting portion 52. Fig. 11 is a cross-sectional view taken along line XI-XI in Fig. 2.

[0041] The first mounting portion 52 has a first inner mounting portion 62 and a first outer mounting portion 72. The first inner mounting portion 62 has a lock protrusion 63. The first outer mounting portion 72 has a lock receiving portion 73.

[0042] The locking protrusions 63 protrude on both sides from the inner cover main body 61. The locking protrusions 63 protrude outward from the outer surfaces of the two side walls 61b. The locking protrusions 63 have a guide surface 63a and an engagement surface 63b. The surface of the locking protrusion 63 facing the negative side in the X direction is the guide surface 63a. The surface of the locking protrusion 63 facing the positive side in the X direction is the engagement surface 63b.

[0043] The lock receiving portion 73 protrudes from both sides from the outer cover main body 71. The lock receiving portion 73 protrudes from both ends of the lid portion 71a. At the position of the lock receiving portion 73, the outer cover main body 71 does not have a side wall 71b, and instead has the lock receiving portion 73. The lock receiving portion 73 has an extension piece 73a and a locking piece 73b. A pair of extension pieces 73a protrude from each end of the lid portion 71a. The pair of extension pieces 73a are separated from each other in the Z direction, which is the extension direction of the electric wire 20. The locking piece 73b connects the tip ends of the pair of extension pieces 73a to each other. A lock recess 73c is formed in the portion surrounded by the extension piece 73a and the locking piece 73b.

[0044] When the first mounting portion 52 is mounted, the locking piece 73b moves along the guide surface 63a. As a result, the inner cover member 60 is elastically deformed so that the distance between the pair of locking projections 63 narrows, or the outer cover member 70 is elastically deformed so that the distance between the pair of lock receiving portions 73 widens, or both are elastically deformed, and the locking piece 73b climbs over the locking projection 63. As a result, the locking projection 63 fits into the locking recess 73c, and the first mounting portion 52 is in the mounted state.

[0045] A direction intersecting a plane including the first direction (X direction) and the second direction (Z direction) is defined as a third direction. The third direction is, for example, the Y direction. When observed from the third direction (Y direction), the first attachment portion 52 is located outside the innermost surface of the inner cover main body 61 or inside the outermost surface of the outer cover main body 71. Here, when observed from the third direction (Y direction), the first attachment portion 52 is located outside the innermost surface of the inner cover main body 61 and inside the outermost surface of the outer cover main body 71. When observed from the third direction (Y direction), the first attachment portion 52 overlaps with the inner cover main body 61 and the outer cover main body 71.

[0046] 2 is a view observed from the third direction (Y direction). As shown in FIG. 2, the first attachment portion 52 is located outside (negative side in the X direction) of the innermost surface (surface on the positive side in the X direction) of the inner cover main body 61, or inside (positive side in the X direction) of the outermost surface (surface on the negative side in the X direction) of the outer cover main body 71. Here, the first attachment portion 52 is located outside (negative side in the X direction) of the innermost surface (surface on the positive side in the X direction) of the inner cover main body 61 and inside (positive side in the X direction) of the outermost surface (surface on the negative side in the X direction) of the outer cover main body 71. The first attachment portion 52 overlaps with the inner cover main body 61 and the outer cover main body 71.

[0047] The first attachment portion 52 in this example is a lock portion. At one end including the first attachment portion 52, the inner cover member 60 and the outer cover member 70 are locked in any of the first direction (X direction), the second direction (Z direction), and the third direction (Y direction). Specifically, in the X direction, the locking surface 63b and the locking piece 73b are locked in the direction in which the inner cover member 60 and the outer cover member 70 move away from each other. In the X direction, the side wall 61b and the lid portion 71a are locked in the direction in which the inner cover member 60 and the outer cover member 70 move toward each other. In the Y direction, the lock receiving portion 73 and the side wall 61b are locked. In the Z direction, the extension piece 73a of the lock receiving portion 73 and the side surface of the lock protrusion 63 are locked.

[0048] <Second mounting part> The second mounting portion 54 will be described with further reference to Fig. 12. Fig. 12 is a cross-sectional view showing the second mounting portion 54. Fig. 12 is a cross-sectional view taken along line XII-XII in Fig. 2.

[0049] The second attachment portion 54 has a second inner attachment portion 64 and a second outer attachment portion 74. At the other end portion including the second attachment portion 54, the inner cover member 60 and the outer cover member 70 overlap in the second direction (Z direction) and the third direction (Y direction) and are engaged in the second direction (Z direction) and the third direction (Y direction) of the first direction (X direction), the second direction (Z direction) and the third direction (Y direction). Here, at the other end portion including the second attachment portion 54, the inner cover member 60 and the outer cover member 70 overlap in three or more layers along each of the second direction (Z direction) and the third direction (Y direction). Here, at the other end portion including the second attachment portion 54, the inner cover member 60 and the outer cover member 70 overlap in four or more layers along each of the second direction (Z direction) and the third direction (Y direction).

[0050] Specifically, the second inner mounting portion 64 has a first inward convex portion 65, a second inward convex portion 66, and an outward convex portion 67. The second outer mounting portion 74 has an inward convex portion 75 and an outward convex portion 76. In FIG. 12, the cover body 51 is shown by virtual lines. The convex portions 65, 66, 67 of the second inner mounting portion 64 are portions that protrude from the inner cover body 61. The convex portions 75, 76 of the second outer mounting portion 74 are portions that protrude from the outer cover body 71.

[0051] The first inward protrusion 65 protrudes inward from the inner surface of the side wall 61b at the tip end of the side wall 61b. The second inward protrusion 66 protrudes inward from the inner surface of the side wall 61b at the base end of the side wall 61b. The first inward protrusion 65 and the second inward protrusion 66 are spaced apart in the second direction (Z direction).

[0052] The outward protrusion 67 protrudes outward from the support portion 61c. The outward protrusion 67 covers the outside of the side wall 71b. As shown in Fig. 4, in the X direction, the first inward protrusion 65 is longer than the second inward protrusion 66 and the outward protrusion 67. In the X direction, the outward protrusion 67 is longer than the second inward protrusion 66.

[0053] The inward protrusion 75 protrudes inward from the inner surface of the cover portion 71a. The outward protrusion 76 protrudes outward from the outer surface of the tip of the inward protrusion 75. The outward protrusion 76 fits between the first inward protrusion 65 and the second inward protrusion 66. As shown in Fig. 5, the inward protrusion 75 and the outward protrusion 76 reach from the other end of the outer cover main body 71 to the inner surface at the position of the bent portion in the X direction.

[0054] In the second direction (Z direction), the inner cover member 60 and the outer cover member 70 are alternately stacked to form four layers. In the second direction (Z direction), the lid portion 71a, the first inward convex portion 65, the outward convex portion 76, and the second inward convex portion 66 are stacked in this order from the positive side to the negative side to form four layers. This makes it difficult for the second mounting portion 54 to come off in the second direction (Z direction) and difficult for the opening to occur. The second inward convex portion 66 reaches the connecting portion of the bottom wall 61a in the second direction (Z direction). In this respect, too, the second mounting portion 54 is difficult to come off in the second direction (Z direction) and difficult for the opening to occur.

[0055] For example, the second inward convex portion 66 may be omitted, and the inner cover member 60 and the outer cover member 70 may be alternately stacked in the second direction (Z direction) to form three layers. In the second direction (Z direction), it is preferable that the inner cover member 60 and the outer cover member 70 are alternately stacked in three or more layers.

[0056] In the third direction (Y direction), the inner cover members 60 and the outer cover members 70 are alternately stacked to form four layers. In the third direction (Y direction), on each side sandwiching the electric wire 20, the outward convex portion 76, the side wall 61b, the side wall 71b, and the outward convex portion 67 are stacked in this order from the inside (the electric wire 20 side) to the outside to form four layers. This makes it difficult for the second attachment portion 54 to come off and to open in the third direction (Y direction).

[0057] For example, either the outward convex portion 67 or the outward convex portion 76 may be omitted, and the inner cover member 60 and the outer cover member 70 may be alternately overlapped in the third direction (Y direction) to form three layers. Both the outward convex portion 67 and the outward convex portion 76 may be omitted, and the inner cover member 60 and the outer cover member 70 may be alternately overlapped in the third direction (Y direction) to form two layers. The inner cover member 60 and the outer cover member 70 overlap each other on one side and the other side in the third direction (Y direction). Therefore, even if the inner cover member 60 and the outer cover member 70 overlap in two layers of the side wall 61b and the side wall 71b in the third direction (Y direction), they are prevented from coming off.

[0058] When observed from the third direction (Y direction), the second attachment portion 54 is located outside the innermost surface of the inner cover main body 61 or inside the outermost surface of the outer cover main body 71. Here, when observed from the third direction (Y direction), the first attachment portion 52 and the second attachment portion 54 are located outside the innermost surface of the inner cover main body 61 and inside the outermost surface of the outer cover main body 71. When observed from the third direction (Y direction), the first attachment portion 52 and the second attachment portion 54 overlap with the inner cover main body 61 and the outer cover main body 71.

[0059] 2, the second attachment portion 54 is located outside (positive side in the Z direction) of the innermost surface (negative side in the Z direction) of the inner cover main body 61, or inside (negative side in the Z direction) of the outermost surface (positive side in the Z direction) of the outer cover main body 71. Here, the second attachment portion 54 is located outside (positive side in the Z direction) of the innermost surface (negative side in the Z direction) of the inner cover main body 61 and inside (negative side in the Z direction) of the outermost surface (positive side in the Z direction) of the outer cover main body 71. The second attachment portion 54 overlaps with the inner cover main body 61 and the outer cover main body 71.

[0060] The inner cover member 60 and the outer cover member 70 move relatively along the first direction (X direction) to attach the first attachment portion 52 and the second attachment portion 54, respectively. At the other end including the second attachment portion 54, the inner cover member 60 and the outer cover member 70 are not locked in the first direction (X direction). The second inner attachment portion 64 and the second outer attachment portion 74 are movable in the first direction (X direction) like the relationship between a slider and a rail, but are not disengaged in the second direction (Z direction) and the third direction (Y direction).

[0061] The wire cover 50 is provided at one end or the other end with a mounting portion 59 that fits into the rear end of the connector 30. In this example, the mounting portion 59 that fits into the rear end of the connector 30 is provided at one end of the wire cover 50.

[0062] The mounting portion 59 has an inner groove 69 formed on the inner surface of the inner cover main body 61 and an outer groove 79 formed on the inner surface of the outer cover main body 71. The flange portion 32 at the rear end of the connector 30 fits into the inner groove 69 and the outer groove 79. The inner cover main body 61 has a thick portion around the periphery where the inner groove 69 is formed. The inner cover main body 61 has a locking protrusion 63 provided outside the inner groove 69.

[0063] The wire cover 50 has a cylindrical member mounting portion 58 at the other end thereof which overlaps with the cylindrical member 40. The cylindrical member 40 is attached by an inner mounting portion 68 of the inner cover body 61 and an outer mounting portion 78 of the outer cover body 71. The tip edge of the second inward convex portion 66 forms the inner mounting portion 68. The tip edge of the inward convex portion 75 forms the outer mounting portion 78.

[0064] The cylindrical member mounting portion 58 sandwiches the cylindrical member 40. One end of the cylindrical member 40 is inserted into the wire cover 50 through the cylindrical member mounting portion 58. The other end of the cylindrical member 40 protrudes outside the wire cover 50 through the cylindrical member mounting portion 58.

[0065] The inner surface of the tubular member mounting portion 58 is shaped according to the outer surface of the tubular member 40. Here, since the outer surface of the tubular member 40 is circular, the inner surface of the tubular member mounting portion 58 is also circular. The inner mounting portion 68 and the outer mounting portion 78 are each semicircular. The tubular member mounting portion 58 holds the tubular member 40 without crushing it. The size of the inner surface of the tubular member mounting portion 58 is the same as or slightly larger than the size of the outer surface of the tubular member 40. The tubular member mounting portion 58 may hold the tubular member 40 by crushing it. The size of the inner surface of the tubular member mounting portion 58 may be slightly smaller than the size of the outer surface of the tubular member 40.

[0066] One end of the tubular member 40 may be inserted into the wire cover 50 through the tubular member attachment portion 58 after the wire cover 50 is attached to the bent portion 12. With one end of the tubular member 40 positioned on the inner attachment portion 68, the inner cover member 60 and the outer cover member 70 may move relatively along the first direction (X direction) to attach the wire cover 50 to the bent portion 12.

[0067] The other end of the cylindrical member 40 may be fixed to the electric wire 20. The cylindrical member 40 and the electric wire 20 may be fixed to each other by wrapping a bundling member such as an adhesive tape or a cable tie around the cylindrical member 40 and the electric wire 20.

[0068] The cylindrical member mounting portion 58 may be configured so that the cylindrical member 40 is mounted on the outside of the wire cover 50. For example, the cylindrical member mounting portion 58 having an outer diameter approximately equal to the inner diameter of the cylindrical member 40 may protrude outward from the cover body 51 along the extending direction of the electric wires 20, and the cylindrical member mounting portion 58 may be covered with the cylindrical member 40.

[0069] The inner cover member 60 and the outer cover member 70 are each injection molded products made of resin. They are formed in a shape without undercuts so that the mold can be removed from the top and bottom. Here, the X direction is the direction in which the mold is removed. The inner cover member 60 and the outer cover member 70 are each formed in a shape without undercuts in the X direction. A shape without undercuts in the X direction means that there is no part in which a convex portion, a concave portion, and a convex portion are consecutive in this order in the X direction at any position on the YZ plane. If there is a part in which a convex portion, a concave portion, and a convex portion are consecutive in this order in the X direction, the concave portion is hidden in both of Figures 8 and 9 observed from both sides in the X direction. Therefore, it can also be said that a shape without undercuts in the X direction means that there is no hidden concave portion in both of Figures 8 and 9 observed from both sides in the X direction.

[0070] A drain hole 80 may be formed in at least one of the inner cover body 61 and the outer cover body 71. In Figs. 8 and 9, the drain hole 80 is shown by a virtual line. The drain hole 80 in the inner cover body 61 may be, for example, a through hole penetrating the bottom of the inner cover body 61. The drain hole 80 in the outer cover body 71 may be, for example, a through hole penetrating the lid portion 71a of the outer cover body 71. The position where the drain hole 80 is formed in the inner cover body 61 and the outer cover body 71 may be any position. For example, it may be on one end side or the other end side with respect to the bent portion 12. Here, the drain hole 80 is provided between the bent portion 12 and one end.

[0071] <Effects, etc.> According to the wire cover 50 configured as above and the wiring member 10 including the same, in the wire cover 50 that holds the bent portion 12 of the wire 20, the first attachment portion 52 and the second attachment portion 54 are provided so as to avoid the inside and outside of the bent portion 12. Therefore, a space can be secured at least on either the inside or the outside of the bent portion 12.

[0072] Moreover, the first attachment portion 52 is a locking portion that engages in any of the first direction (X direction), the second direction (Z direction), and the third direction (Y direction), and the second attachment portion 54 is a locking portion that engages in the second direction (Z direction) and the third direction (Y direction). This makes it easy to fix the inner cover member 60 and the outer cover member 70 by the first attachment portion 52 and the second attachment portion 54.

[0073] Furthermore, in the second attachment portion 54, the inner cover member 60 and the outer cover member 70 are overlapped in three or more layers along each of the second direction (Z direction) and the third direction (Y direction), making it difficult for the second attachment portion 54 to open in the second direction (Z direction) and the third direction (Y direction).

[0074] In addition, in the second attachment portion 54, the inner cover member 60 and the outer cover member 70 are overlapped in four or more layers along each of the second direction (Z direction) and the third direction (Y direction). This makes the second attachment portion 54 more difficult to open in the second direction (Z direction) and the third direction (Y direction).

[0075] Further, in the inner cover body 61 and the outer cover body 71, an attachment portion 59 that fits into the rear end portion of the connector 30 is provided at one end or the other end. This allows the wire cover 50 to be attached to the connector 30 and to hold the bent portion 12 of the wire 20 extending from the connector 30.

[0076] The mounting portion 59 is provided at one end of the inner cover main body 61 and the outer cover main body 71, and the flange portion 32 at the rear end of the connector 30 fits into the inner groove 69 and outer groove 79 of the mounting portion 59. As a result, the flange portion 32 at the rear end of the connector 30 fits into the inner groove 69 and outer groove 79, and the mounting portion 59 can be provided at one end where the lock portion is located, which makes it easier to stabilize the mounting state at the rear end of the connector 30.

[0077] Further, the inner cover body 61 and the outer cover body 71 are provided at the other end with a cylindrical member attachment portion 58 that overlaps with the cylindrical member 40. This allows the cylindrical member 40, such as a rubber hose, to be attached to the wire cover 50.

[0078] Further, a water drainage hole 80 is formed in at least one of the inner cover body 61 and the outer cover body 71. This allows water inside the wire cover 50 to escape to the outside of the wire cover 50 through the water drainage hole 80.

[0079] In addition, the inner cover member 60 and the outer cover member 70 are each injection molded products, and are formed in a shape without undercuts so that they can be removed from the top and bottom of the mold. This simplifies the shape of the mold and helps prevent costs from increasing.

[0080] Furthermore, according to the wiring member 10 including the electric wire 20 and the electric wire cover 50, the bent portion 12 of the electric wire 20 is held by the electric wire cover 50, and space can be secured at least on either the inside or the outside of the bent portion 12.

[0081] [Note] FIG. 13 is a side view showing a modified example of the wiring member 10. As shown in FIG.

[0082] In the above example, the wire cover 50 is attached to the bent portion 12 of the electric wire 20 extending from the connector 30. However, the wire cover 50 may be attached to other bent portions 12. For example, as in the wiring member 110 shown in FIG. 13, the wire cover 50 may be attached to the bent portion 12 of the branched portion. In the example shown in FIG. 13, a plurality of electric wires 20 are branched from a trunk line 21 into a plurality of branch lines 22. The trunk line 21 is provided with a bent portion 12. The wire cover 50 holds the bent portion 12 of the trunk line 21. A plurality of branch lines 22 extend from the wire cover 50 and branch out. The wire cover 50 may be attached to one of the branch lines 22. The wire cover 50 may hold the bent portion of the branch line 22.

[0083] In addition, although the wire cover 50 has been described above as being provided with the mounting portion 59, this is not an essential configuration. When the wire cover 50 is not attached to the rear end portion of the connector 30 as in the example of Fig. 13, the mounting portion 59 may be omitted.

[0084] In addition, it has been described so far that the inner cover member 60 and the outer cover member 70 overlap in the second direction (Z direction) and the third direction (Y direction) at the other end including the second attachment portion 54 and are engaged in the second direction (Z direction) and the third direction (Y direction) among the first direction (X direction), the second direction (Z direction) and the third direction (Y direction), but this is not a required configuration. For example, even at the other end including the second attachment portion 54, the inner cover member 60 and the outer cover member 70 may be engaged in any of the first direction (X direction), the second direction (Z direction) and the third direction (Y direction).

[0085] Further, although the wire cover 50 has been described so far as being provided with the cylindrical member attachment portion 58, this is not an essential configuration. The cylindrical member attachment portion 58 may be omitted.

[0086] Further, although the wire cover 50 has been described above as being provided with the drainage holes 80, this is not an essential configuration. The drainage holes 80 may be omitted.

[0087] Although the inner cover member 60 and the outer cover member 70 have been described so far as being formed in a shape without an undercut, this is not a required configuration. Either or both of the inner cover member 60 and the outer cover member 70 may be formed in a shape with an undercut. In this case, the inner cover member 60 or the outer cover member 70 with an undercut can be formed using a so-called slide mold.

[0088] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
