[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.
[0010] The fixing member of the present disclosure is as follows.
[0011] (1) A fixing member for fixing a flat wiring member to a fixing object, the fixing object including a placement surface on which the flat wiring member is placed and a first plate-shaped edge portion provided at one end of the placement surface, the fixing member being equipped with a pressing portion for pressing the flat wiring member from the opposite side to the placement surface, a hooking portion protruding from the pressing portion to one side of the flat wiring member and hooking onto the first plate-shaped edge portion, and a fixing portion protruding from the pressing portion to the other side of the flat wiring member and fixed to the fixing object.
[0012] According to the fixing member of (1), by providing a hook portion that hooks onto the plate-like edge portion, the flat wiring member can be suitably fixed to a fixing object that includes the plate-like edge portion.
[0013] (2) In the fixing member of (1), the fixing target may include a second plate-shaped edge portion provided at the other end of the arrangement surface, and the fixing portion may have a shape that hooks onto the second plate-shaped edge portion. This allows the flat wiring member to be suitably fixed to the fixing target that includes plate-shaped edges at both ends of the arrangement surface.
[0014] (3) In the fixing member of (2), the hooking portion and the fixing portion may each be formed in multiple steps along a height direction from the mounting surface. This allows the steps at which the hooking portion and the fixing portion hook onto the plate-like edge portion to be changed. This allows the height of the pressing portion relative to the mounting surface to be changed depending on the thickness of the flat wiring member.
[0015] (4) In the fixing member of (1), the fixing target may include a locking surface protruding from the other end of the arrangement surface in a direction intersecting the arrangement surface and a locking hole formed in the locking surface, and the fixing portion may have a shape that locks into the locking hole. This allows the flat wiring member to be suitably fixed to the fixing target including the arrangement surface and the locking surface.
[0016] (5) The fixing member of (4) may further include a hinge portion provided between the pressing portion and the fixing portion, which facilitates the operation of locking the fixing portion into the locking hole after the hook portion is hooked onto the first plate-like edge portion.
[0017] (6) In any one of the fixing members (1) to (5), a holding portion may be provided between the flat wiring member and the placement surface, and the holding portion may hold a side edge of the flat wiring member between the holding portion and the flat wiring member. This allows the fixing member to be attached to the flat wiring member before the flat wiring member is fixed to the fixing object.
[0018] (7) The fixing member of (6) may further include an elastic piece protruding from at least one of the pressing portion and the holding portion toward the flat wiring member. This makes it easier to maintain the fixing member attached to the flat wiring member. Also, it makes it easier to apply one type of fixing member to multiple types of flat wiring members with different thicknesses.
[0019] (8) In the fixing member of any one of (1) to (7), the pressing portion may have a pressing plate portion extending along the flat wiring member and a rib protruding from the pressing plate portion toward the flat wiring member, thereby preventing the fixing member from shifting in position along the extension direction of the flat wiring member.
[0020] (9) In the fixing member of (8), the rib may extend in a direction intersecting the extension direction and width direction of the flat wiring member, thereby making it more difficult for the fixing member to shift position along the extension direction of the flat wiring member.
[0021] [Details of the embodiment of the present disclosure] Specific examples of the fixing member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.
[0022] [Embodiment 1] A fixing member according to embodiment 1 will be described below. Fig. 1 is a plan view showing a fixing member 30 according to embodiment 1 and its mounting structure. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is a perspective view showing the fixing member 30 according to embodiment 1. In each figure, the X direction, Y direction, and Z direction, which are orthogonal to each other, are shown.
[0023] The fixing member 30 fixes the flat wiring member 20 to the object 10. The object 10 and the flat wiring member 20 will be described first.
[0024] The fixed object 10 includes a placement surface 12 and a first plate-shaped edge portion 13. The placement surface 12 is the portion on which the flat wiring member 20 is placed. The first plate-shaped edge portion 13 is provided at one end of the placement surface 12. Here, the fixed object 10 includes a second plate-shaped edge portion 14. The second plate-shaped edge portion 14 is provided at the other end of the placement surface 12. The placement surface 12 is a plane extending along the XY plane. Both ends of the placement surface 12 in the Y direction are the first plate-shaped edge portion 13 and the second plate-shaped edge portion 14. The first plate-shaped edge portion 13 and the second plate-shaped edge portion 14 extend in the X direction. The cross-section of the fixed object 10 shown in Figure 2 is continuous in the X direction.
[0025] Here, the fixed object 10 is formed in a shape in which a plate portion 11 and a tubular portion 15 are joined together. The plate portion 11 and the tubular portion 15 are joined by, for example, welding. The plate portion 11 is a flat plate extending along the XY plane. One main surface of the plate portion 11 forms the placement surface 12. The tubular portion 15 is joined to the other main surface of the plate portion 11. The tubular portion 15 is formed in a cylindrical or rectangular tubular shape. The axis of the tubular portion 15 extends in the X direction. Here, the tubular portion 15 is formed in a rectangular tubular shape. One of the four outer surfaces of the tubular portion 15 is in contact with the other main surface of the plate portion 11. The width dimension of the plate portion 11 in the Y direction is larger than the width dimension of the tubular portion 15 in the Y direction. In a cross-section of the fixed object 10, at least one end of the plate portion 11 in the Y direction protrudes outward from the tubular portion 15. Here, both ends of the plate portion 11 protrude outward from the tubular portion 15. One end of the plate portion 11 in the Y direction forms a first plate-shaped edge portion 13 , and the other end of the plate portion 11 in the Y direction forms a second plate-shaped edge portion 14 .
[0026] Such a fixed object 10 may be, for example, a reinforcement placed in front of an instrument panel. The reinforcement extends along the vehicle width direction and connects the left and right parts of the vehicle body. This increases the rigidity of the vehicle body. The reinforcement also supports the steering shaft, etc. When the fixed object 10 is a reinforcement, in each figure, the X direction is the vehicle width direction, the Y direction is the front-to-rear direction, and the Z direction is the up-down direction. The placement surface 12 is the top surface of the reinforcement.
[0027] The flat wiring member 20 includes a plurality of linear transmission members 21 and a base material 24. The plurality of linear transmission members 21 are held in a lined-up state by the base material. The parallel arrangement direction of the plurality of linear transmission members 21 is the width direction of the flat wiring member 20. The extension direction of the plurality of linear transmission members 21 is the extension direction of the flat wiring member 20. The stacking direction of the base material and the linear transmission members 21 is the height direction or thickness direction of the flat wiring member 20.
[0028] Each linear transmission member 21 includes a transmission line main body 22 and a coating layer 23. The linear transmission member 21 is a linear member that transmits electricity or light. For example, the linear transmission member 21 has the transmission line main body 22 and the coating layer 23. The transmission line main body 22 is a transmission path that transmits electricity or light. For example, if the linear transmission member 21 is an electric wire, the transmission line main body 22 is a conductor core wire. The conductor core wire is composed of one or more element wires. The element wires are formed from copper, copper alloy, aluminum, aluminum alloy, etc. Furthermore, if the linear transmission member 21 is an optical fiber, the transmission line main body 22 is a core and clad. The coating layer 23 is a layer that covers the transmission line main body 22. The resin material that constitutes the coating layer 23 is not particularly limited and can be set as appropriate. For example, the linear transmission member 21 may be a general electric wire having a core wire and a coating layer 23 surrounding the core wire, or may be a shielded wire, a twisted wire, an enameled wire, a nichrome wire, an optical fiber, or the like.
[0029] The linear transmission member 21 that transmits electricity may be any of various signal lines and power lines. A part of the linear transmission member 21 that transmits electricity may be used as an antenna, a coil, or the like that sends or receives a signal or power to or from space.
[0030] Furthermore, the linear transmission member 21 may be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission member 21 with one transmission path. The linear transmission member 21 may be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A multi-core wire is a linear transmission member 21 with multiple transmission paths. A multi-core wire may be, for example, a twisted wire, a cable in which multiple linear objects are assembled and covered with a sheath, or the like.
[0031] The base material 24 holds the plurality of linear transmission members 21 in a flat state. The plurality of linear transmission members 21 are arranged side by side on the main surface of the base material 24. The linear transmission members 21 are fixed to the base material 24, thereby maintaining the parallel state. The base material 24 is formed into a shape corresponding to the path of the linear transmission members 21. In the example shown in FIG. 1 , the base material 24 has only a straight path, but the base material 24 may also have a curved path. Each linear transmission member 21 is fixed to the base material 24, thereby maintaining the linear transmission members 21 in an extended state corresponding to the path.
[0032] The manner in which the linear transmission member 21 and the base material 24 are fixed to each other is not particularly limited and can be set as appropriate. For example, the linear transmission member 21 and the base material 24 may be fixed to each other by fusion. In this case, a resin contained in at least one of the coating of the linear transmission member 21 and the main surface of the base material 24 melts and adheres to the surface of the mating member to be fixed. Also, for example, the linear transmission member 21 and the base material 24 may be attached to each other by an adhesive or a pressure-sensitive adhesive.
[0033] The base material 24 is, for example, a flexible sheet material. The sheet material has flexibility that allows it to follow the bending of the linear transmission member 21. The base material 24 may also be a sheet that is hard enough to bend. For example, the sheet material may be a sheet containing a fibrous material such as a nonwoven fabric. The sheet material may also be a sheet having a solid cross section. The sheet material may also be a composite sheet in which multiple layers are laminated.
[0034] For example, when the linear transmission member 21 is fused and fixed to a sheet material, the sheet material may have a single-layer structure consisting of only a fusion layer, or may have a laminated structure consisting of a fusion layer and an additional layer. The fusion layer is a layer that is fused to the linear transmission member 21. For example, the fusion layer is made of the same type of resin material as the resin material that mainly constitutes the coating layer 23 of the linear transmission member 21. Such a resin material is, for example, PVC or polyolefin. The additional layer imparts functions that the fusion layer does not have or enhances the functions that the fusion layer has. For example, the fusion layer may be made of a sheet having a solid cross-section, and the additional layer may be made of a fibrous sheet such as a nonwoven fabric.
[0035] In the example shown in Fig. 2, the flat wiring member 20 has a laminated structure in which a plurality of flat wiring bodies 25, each of which includes a plurality of linear transmission members 21 and a base material 24, are stacked. The base materials 24 are joined together by fusion or the like to maintain the laminated structure. In the flat wiring body 25 of the outermost layer, the base material 24 is positioned outside the linear transmission members 21. As a result, the linear transmission members 21 of each layer are arranged between the base materials 24. The flat wiring member 20 may also have a single-layer structure in which only one flat wiring body 25 including the base material 24 and the linear transmission members 21 is provided.
[0036] The flat wiring member 20 has a wiring main body 26 and side edges 27. The wiring main body 26 is a portion of the base material 24 where the linear transmission member 21 is arranged. The side edges 27 are portions of the base material 24 where the linear transmission member 21 is not arranged. Because the linear transmission member 21 is not arranged at the side edges 27, the thickness dimension of the wiring main body 26 is greater than the thickness dimension of the side edges 27. The portion of the flat wiring member 20 located at the middle in the width direction is the wiring main body 26. The portions of the flat wiring member 20 located at both ends in the width direction are the side edges 27. The side edges 27 have joints where the base materials 24 of the flat wiring body 25 are joined together.
[0037] At least one fixing member 30 is provided. Here, the fixing members 30 are provided at multiple locations spaced apart along the extension direction of the flat wiring member 20. Here, the fixing members 30 are longer in the width direction than in the extension direction of the flat wiring member 20. The fixing member 30 includes a pressing portion 32, a hook portion 36, and a fixing portion 40.
[0038] The pressing portion 32 presses the flat wiring member 20 from the side opposite to the placement surface 12. The pressing portion 32 may be configured to press the flat wiring member 20 toward the placement surface 12. The pressing portion 32 traverses the flat wiring member 20. The pressing portion 32 extends from one end to the other end along the width direction of the flat wiring member 20.
[0039] The pressing portion 32 has a main body pressing portion 33. The main body pressing portion 33 presses the wiring main body 26. Here, the pressing portion 32 has a side edge pressing portion 34. The side edge pressing portion 34 presses the side edge 27. Because the thickness of the side edge 27 is smaller than the thickness of the wiring main body 26, the side edge pressing portion 34 protrudes more toward the plate portion 11 in the Z direction than the main body pressing portion 33.
[0040] The hook portion 36 protrudes from the pressing portion 32 toward one side of the flat wiring member 20. The hook portion 36 hooks onto the first plate-shaped edge portion 13. The hook portion 36 has a support portion 37 and a claw portion 38. The support portion 37 extends in a direction perpendicular to the arrangement surface 12, outside the arrangement surface 12 in the Y direction. The support portion 37 extends in the Z direction from one main surface side of the plate portion 11 (the upper surface of the plate portion 11 in FIG. 2 ) to the other main surface side (the lower surface of the plate portion 11 in FIG. 2 ). The claw portion 38 protrudes from the tip of the support portion 37 on the other main surface side of the plate portion 11 toward the plate portion 11 along the Y direction. The claw portion 38 hooks onto the other main surface of the plate portion 11. The dimension of the first plate-shaped edge portion 13 in the Y direction is equal to or greater than the dimension of the claw portion 38 in the Y direction.
[0041] Here, the hook portion 36 has a clamping portion 39. The clamping portion 39 protrudes from the tip of the support portion 37 on one main surface side of the plate portion 11 toward the plate portion 11 along the Y direction. The clamping portion 39 contacts one main surface of the plate portion 11. The clamping portion 39 clamps the plate portion 11 in the Z direction together with the claw portion 38. The hook portion 36 hooks onto the plate portion 11 in both directions in the Z direction. The clamping portion 39 is connected to the side edge pressing portion 34.
[0042] The fixing portion 40 protrudes from the pressing portion 32 toward the other side of the flat wiring member 20. The fixing portion 40 is fixed to the fixing object 10. Here, the fixing portion 40 has a shape that hooks onto the second plate-shaped edge portion 14. Here, the fixing portion 40 is formed in the same shape as the hooking portion 36. Therefore, like the hooking portion 36, the fixing portion 40 has a support portion 37, a claw portion 38, and a clamping portion 39. Because the fixing portion 40 has the same shape as the hooking portion 36, the fixing member 30 has a shape that is line-symmetrical with respect to a line extending in the Z direction.
[0043] The hooking portion 36 does not have a portion that prevents the hooking portion 36 from coming off in the Y direction. The fixing portion 40 prevents the hooking portion 36 from coming off in the Y direction. In other words, when the hooking portion 36 is hooked on the first plate-shaped edge portion 13 and the fixing portion 40 is not fixed, the hooking portion 36 can move in the Y direction relative to the first plate-shaped edge portion 13 and away from the first plate-shaped edge portion 13. Therefore, in this state, the hooking portion 36 can easily come off the first plate-shaped edge portion 13. When the hooking portion 36 is hooked on the first plate-shaped edge portion 13 and the fixing portion 40 is fixed, the hooking portion 36 cannot move in the Y direction relative to the first plate-shaped edge portion 13 and away from the first plate-shaped edge portion 13. Therefore, in this state, the hooking portion 36 is maintained in a hooked state on the first plate-shaped edge portion 13.
[0044] The fixing portion 40 does not have a portion that prevents the fixing portion 40 from coming off in the Y direction. The hook portion 36 serves to prevent the fixing portion 40 from coming off in the Y direction. In other words, when the hook portion 36 is not hooked on the first plate-shaped edge portion 13 and the fixing portion 40 is fixed (when the fixing portion 40 is hooked on the second plate-shaped edge portion 14), the fixing portion 40 can move in the Y direction relative to the second plate-shaped edge portion 14 in a direction away from the second plate-shaped edge portion 14. Therefore, in this state, the fixing portion 40 can easily come off from the second plate-shaped edge portion 14. When the hook portion 36 is hooked on the first plate-shaped edge portion 13 and the fixing portion 40 is fixed (when the fixing portion 40 is hooked on the second plate-shaped edge portion 14), the fixing portion 40 cannot move in the Y direction relative to the second plate-shaped edge portion 14 in a direction away from the second plate-shaped edge portion 14. Therefore, in this state, the fixing portion 40 is held in a state where it is hooked onto the second plate-shaped edge portion 14 .
[0045] The hooking portion 36 and the fixing portion 40 may be configured so that one can be hooked and then the other can be hooked, as in the example shown by the imaginary lines in Figure 2. In this case, the fixing member 30 is elastically deformable so that the other claw portion 38 spreads outward from the plate-shaped edge portion so that the other claw portion 38 can pass over the plate-shaped edge portion. The hooking portion 36 and the fixing portion 40 may be configured so that they can be hooked at the same time. When the claw portion 38 passes over the plate-shaped edge portion, the surface opposite to the surface that hooks on the plate-shaped edge portion comes into contact with one main surface of the plate-shaped edge portion, and the fixing member 30 is elastically deformable so that the other claw portion 38 spreads outward from the plate-shaped edge portion.
[0046] <Effects, etc.> The fixing member 30 configured as described above is provided with the hook portion 36 that hooks onto the plate-like edge portion, so that the flat wiring member 20 can be suitably fixed to the fixing object 10 that includes the plate-like edge portion.
[0047] Furthermore, since the fixing portion 40 has a shape that hooks onto the second plate-shaped edge portion 14 , the flat wiring member 20 can be suitably fixed to the fixing object 10 that includes plate-shaped edges on both ends of the placement surface 12 .
[0048] [Embodiment 2] A fixing member according to embodiment 2 will be described. Fig. 4 is a cross-sectional view showing a fixing member 130 according to embodiment 2 and its mounting structure. In Fig. 4, the fixing member 130 shown in imaginary lines is in a state before mounting. Fig. 5 is a perspective view showing the fixing member 130 according to embodiment 2. Fig. 6 is a cross-sectional view showing another mounting example of the fixing member 130 according to embodiment 2. In the following description, components similar to those described so far are assigned the same reference numerals, and their description will be omitted.
[0049] In this embodiment, the shape of the target 10 is the same as the shape of the target 10 described above. In this embodiment, the shape of the fixing member 130 is different from the shape of the fixing member 30 described above. In the fixing member 130, the hooking portion 136 and the fixing portion 140 are each formed in multiple steps along the height direction (Z direction) from the placement surface 12. This makes it possible to change the steps at which the hooking portion 136 and the fixing portion 140 hook onto the plate-like edge portions 13, 14. This makes it possible to change the height of the pressing portion 32 relative to the placement surface 12 depending on the thickness of the flat wiring members 20, 120, as in the examples shown in FIGS. 4 and 6 .
[0050] Specifically, in the hook portion 136 and the fixed portion 140, multiple claw portions 138 protrude from one support portion 137. The multiple claw portions 138 are formed at intervals from one another in the Z direction. The number of claw portions 138 is the number of steps in the hook portion 136 and the fixed portion 140. In the example shown in Figure 4, the number of steps is four. The number of steps may be two or three, or may be five or more. The spacing between the claw portions 138 is the step spacing. Dimension D in Figure 4 is the spacing between adjacent steps. Here, the spacing between adjacent steps is constant. If the number of steps is three or more, the spacing between adjacent steps may be different.
[0051] As shown by the phantom lines in FIG. 4 , in the fixing member 130 in its natural, undeformed state before attachment, the pressing portion 132 is formed in an arc shape. The pressing portion 132 does not have the side edge pressing portion 34. The main body pressing portion 133 of the pressing portion 132 is formed in an arc shape. The inner widthwise portion of the pressing portion 132 protrudes toward the flat wiring member 20 more than the outer widthwise portion. As shown by the solid lines in FIG. 4 , the pressing portion 132 can bend upward in the Z direction. For example, the amount of bending of the pressing portion 132 in the Z direction is equal to or greater than the distance between the steps of the hook portion 136 and the fixing portion 140 in the Z direction (dimension D in FIG. 4 ). This makes it easier for the pressing portion 132 to press the flat wiring member 20 toward the placement surface 12 at any step.
[0052] The outer surfaces of the claw portions 138 are guide surfaces. The guide surfaces are formed so as to move away from the plate portion 11 from the Y-direction tip to the Y-direction base end. This makes it easy for the fixing member 130 to elastically deform so that the claw portions 138 spread outward in the Y direction when the fixing member 130 receives a reaction force when the guide surfaces come into contact with one main surface of the plate portion 11.
[0053] In the example shown in Fig. 4, the pressing portion 132 does not have a side edge pressing portion 34. In the example shown in Fig. 6, the flat wiring member 120 has a structure in which five flat wiring bodies 25 are stacked. The side edges 27 of the base material 24 of the flat wiring body 25 in the intermediate layer are not joined to the side edges 27 of the other base materials 24. The side edges 27 of the base material 24 of the flat wiring body 25 in the intermediate layer may also be joined to the side edges 27 of the other base materials 24.
[0054] [Embodiment 3] A fixing member according to embodiment 3 will be described. Fig. 7 is a cross-sectional view showing a fixing member 230 and its mounting structure according to embodiment 3. Fig. 8 is a perspective view showing the fixing member 230 according to embodiment 3.
[0055] In this embodiment, the shape of the fixed object 210 and the shape of the fixing member 230 are different from the shapes of the fixed object 10 and the shapes of the fixing member 30. The fixed object 210 does not include a second plate-shaped edge portion 14. Instead, the fixed object 210 includes a locking surface 16 and a locking hole 17. The locking surface 16 protrudes from the other end of the placement surface 12 in a direction intersecting with the placement surface 12. The locking hole 17 is formed in the locking surface 16. Here, only one end of the plate portion 11 protrudes outside the tubular portion 15. The surface of the tubular portion 15 that is continuous with the surface on which the plate portion 11 is provided forms the locking surface 16. The locking hole 17 is a through hole that penetrates between the outer surface and the inner surface of the tubular portion 15.
[0056] The fixing portion 240 of the fixing member 230 has a shape that can be locked into the locking hole 17. This allows the flat wiring member 20 to be suitably fixed to the fixing target 210, which includes the placement surface 12 and the locking surface 16.
[0057] The fixing portion 240 has a support portion 237 and a fitting portion 242. The support portion 237 is longer downward than the support portion 37. The support portion 237 extends to the edge of the locking hole 17. The fitting portion 242 protrudes from the tip of the support portion 237 toward the locking hole 17. The fitting portion 242 is formed in a U-shape. The fitting portion 242 fits into the locking hole 17. This fixes the fixing portion 240 to the fixing object 210.
[0058] Similar to the fixed portion 40, the fixed portion 240 does not have a portion that prevents the fixed portion 240 from coming off in the Y direction. The fitting portion 242 does not have a portion that prevents the fixed portion 240 from coming off from the locking hole 17. The catch portion 36 plays the role of preventing the fixed portion 240 from coming off in the Y direction.
[0059] 7 , the hooking portion 36 and the fixing portion 240 may be configured so that the fitting portion 242 of the fixing portion 240 can be fitted into the locking hole 17 after the hooking portion 36 is hooked. In this case, the fixing member 230 is elastically deformable so that the fitting portion 242 of the fixing portion 240 extends outward beyond the locking surface 16 so that the fitting portion 242 of the fixing portion 240 can move along the locking surface 16.
[0060] When the fixed object 210 is a reinforcement, the hook portion 36 may be located at the rear of the vehicle and the fixing portion 240 may be located at the front of the vehicle. Alternatively, the hook portion 36 may be located at the front of the vehicle and the fixing portion 240 may be located at the rear of the vehicle.
[0061] [Fourth embodiment] A fixing member according to a fourth embodiment will be described. Fig. 9 is a cross-sectional view showing a fixing member 330 and its mounting structure according to the fourth embodiment. Fig. 10 is a perspective view showing the fixing member 330 according to the fourth embodiment.
[0062] In this embodiment, the shape of the fixed object 210 is the same as the shape of the fixing member 230 described in the third embodiment. The shape of the fixing member 330 is different from the shape of the fixing member 230. The fixing member 330 includes a hinge portion 350. The hinge portion 350 is provided between the pressing portion 332 and the fixing portion 340. The thickness of the hinge portion 350 is thinner than the thickness of the pressing portion 332, for example. This allows the hinge portion 350 to deform more easily than the pressing portion 332. As shown by the phantom lines in FIG. 7 , the hook portion 36 and the fixing portion 340 are configured such that, after the hook portion 36 is hooked, the hinge portion 350 can be deformed to move the fixing portion 340 to the locking hole 17. This facilitates the operation of locking the fixing portion 340 into the locking hole 17 after the hook portion 36 is hooked onto the first plate-shaped edge portion 13.
[0063] The shape of the fixing portion 340 is also different from the shape of the fixing portion 240. The fixing portion 340 does not have the fitting portion 242. Instead, the fixing portion 340 has a clamp portion 344. The clamp portion 344 has a pillar portion 345 and a locking piece 346. The support portion 337 of the fixing portion 340 extends to a portion facing the locking hole 17. The pillar portion 345 protrudes from a portion of the support portion 337 facing the locking hole 17. The locking piece 346 protrudes from the tip of the pillar portion 345 toward the support portion 337. The locking piece 346 locks onto the inner surface of the tubular portion 15 around the periphery of the locking hole 17. The clamp portion 344 has a structure in which the locking piece 346 prevents the fixing portion 340 from slipping out of the locking hole 17. This makes it easier for the fixing portion 340 to remain locked into the locking hole 17 even if the hinge portion 350 is easily deformed.
[0064] 9, the pressing portion 332 differs from the pressing portion 32 in that it does not have the side edge pressing portion 34. Therefore, the main body pressing portion 333 is connected to the hook portion 36. Also in the example shown in FIG. 9, the support portion 337 of the hook portion 336 is connected to the main body pressing portion 333. The clamping portion 339 protrudes from the support portion 337. Also in the example shown in FIG. 9, the flat wiring member 320 has a layered structure in which four flat wiring bodies 25 are stacked.
[0065] [Embodiment 5] A fixing member according to embodiment 5 will be described. Fig. 11 is a cross-sectional view showing a fixing member 430 according to embodiment 5 and its mounting structure. Fig. 12 is a perspective view showing the fixing member 430 according to embodiment 5. Fig. 13 is a bottom view showing the fixing member 430 according to embodiment 5.
[0066] In this embodiment, the shape of the fixing target 210 is the same as the shape of the fixing member 230 described in embodiment 3. The shape of the fixing member 430 is different from the shape of the fixing member 230. The fixing member 430 includes a holding portion 460. The holding portion 460 is positioned between the side edge 27 of the flat wiring member 20 and the placement surface 12 in the Z direction. The holding portion 460 holds the side edge 27 of the flat wiring member 20 between the holding portion 460 and the side edge pressing portion 34. By providing the holding portion 460, the fixing member 430 can be attached to the flat wiring member 20 before fixing the flat wiring member 20 to the fixing target 210. The distance between the holding portion 460 and the side edge pressing portion 34 in the Z direction may be equal to or smaller than the thickness of the side edge 27 of the flat wiring member 20. The distance between the holding portion 460 and the side edge pressing portion 34 in the Z direction may be larger than the thickness of the side edge 27 of the flat wiring member 20.
[0067] The shape of the pressing portion 432 is also different from the shape of the pressing portion 32. The main body pressing portion 433 of the pressing portion 432 has a pressing plate portion 435A and a rib 435B. The pressing plate portion 435A extends along the flat wiring member 20. The pressing plate portion 435A has a shape similar to that of the main body pressing portion 33. The rib 435B protrudes from the pressing plate portion 435A toward the flat wiring member 20. The provision of the rib 435B can prevent the fixing member 430 from shifting in position along the extension direction of the flat wiring member 20. A plurality of ribs 435B are provided. Only one rib 435B may be provided. The rib 435B is formed linearly. The rib 435B may be formed in a dotted shape instead of a linear shape. In this case, the ribs 435B may be arranged in a lattice pattern, for example.
[0068] 13 , the ribs 435B extend in a direction intersecting the extension direction and width direction of the flat wiring member 20. This makes it more difficult for the fixing member 430 to shift position along the extension direction of the flat wiring member 20. However, the ribs 435B may extend parallel to the extension direction or width direction of the flat wiring member 20.
[0069] [Modification of the Fifth Embodiment] FIG. 14 is a cross-sectional view showing a modification of the fixing member 430 according to the fifth embodiment.
[0070] 14 includes an elastic piece 570. The elastic piece 570 protrudes from at least one of the pressing portion 532 and the holding portion 460 toward the flat wiring member 20. By providing the elastic piece 570, the fixing member 530 is easily maintained in a state attached to the flat wiring member 20. Furthermore, one type of fixing member 530 can be easily applied to multiple types of flat wiring members 20 having different thicknesses.
[0071] 14 , the elastic piece 570 protrudes from the pressing portion 532. The pressing portion 532 does not have the side edge pressing portion 34, and the main body pressing portion 533 extends to a position facing the holding portion 460. The elastic piece 570 protrudes from the main body pressing portion 533 to face the holding portion 460. The side edge 27 of the flat wiring member 20 is sandwiched between the elastic piece 570 and the holding portion 460. The elastic piece 570 can bend in the thickness direction. In the initial state before the side edge 27 of the flat wiring member 20 is inserted, the distance between the elastic piece 570 and the holding portion 460 is the same as or smaller than the thickness dimension of the side edge 27 of the flat wiring member 20. When the distance between the elastic piece 570 and the holding portion 460 is smaller than the thickness dimension of the side edge 27 of the flat wiring member 20, the elastic piece 570 bends in the thickness direction when the side edge 27 of the flat wiring member 20 is inserted.
[0072] Here, the elastic piece 570 is a spring piece. The side of the elastic piece 570 that is connected to the pressing portion 32 is the base end, and the opposite side of the base end is the tip end. The tip end of the elastic piece 570 is located outward in the width direction from the base end. The tip end of the elastic piece 570 is located closer to the holding portion 460 in the thickness direction than the base end. The distance between the elastic piece 570 and the portion facing the elastic piece 570 (here, the holding portion 460) gradually decreases toward the outside in the width direction. This makes it easy to insert the side edge 27 of the flat wiring member 20 between the elastic piece 570 and the holding portion 460. The side edge 27 of the flat wiring member 20 inserted between the elastic piece 570 and the holding portion 460 causes the tip of the elastic piece 570 to bend toward the pressing portion 32.
[0073] [Additional Notes] The flat wiring member 20 may be an FPC (flexible printed circuit board) or an FFC (flexible flat cable).
[0074] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory. For example, the fixing portion 40 in the fifth embodiment is the fixing portion 40 in the third embodiment, but it may be the fixing portion 40 in the first, second, or fourth embodiment.
