Mode for Carrying Out the Invention
[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.
[0010] The wire harness of the present disclosure is as follows.
[0011] (1) A protector including a housing portion having a first opening and a second opening, and a mounting portion provided on the side of the first opening of the housing portion, an electric wire passing through the housing portion via the first opening and the second opening, a corrugated tube including a small-diameter cylindrical portion and a large-diameter cylindrical portion that are continuously arranged alternately, and covering at least a portion of the electric wire extending along the mounting portion, and a tightening member wound around the corrugated tube and the mounting portion to tighten the corrugated tube and the mounting portion. The mounting portion has an extending portion extending outside the corrugated tube along the extending direction of the electric wire, and a rib protruding from the extending portion toward the small-diameter cylindrical portion of the corrugated tube and fitting into a recess outside the small-diameter cylindrical portion. In the corrugated tube, a part along the circumferential direction is covered by the mounting portion, and the other part is tightened toward the mounting portion by the tightening member. It is a wire harness. According to the wire harness configured in this way, a part along the circumferential direction of the corrugated tube is covered by the mounting portion, and the other part is tightened toward the mounting portion by the tightening member, so that the rib of the mounting portion is kept in a state of fitting into the recess outside the small-diameter cylindrical portion. Instead of the mounting portion covering the entire circumference of the corrugated tube, since the tightening member is provided in the portion of the corrugated tube that is not covered by the mounting portion, the mounting portion and the tightening member can correspond to corrugated tubes of various diameters.
[0012] (2) In the wire harness of (1), the rib may be provided only at one location along the extending direction of the extending portion. Thereby, even for a plurality of types of corrugated tubes with different intervals between the small-diameter cylindrical portions along the extending direction, the rib can easily fit into the recess outside the small-diameter cylindrical portion.
[0013] (3) In the wire harness of (1) or (2), the mounting portion may have a restricting portion provided outside the extending portion to restrict the position of the fastening member. Thereby, it becomes difficult for the fastening member to be displaced with respect to the mounting portion.
[0014] (4) In any one of the wire harnesses from (1) to (3), the fastening member may be provided at the same position as the rib along the extending direction of the extending portion. Thereby, since the portion on the side opposite to the side where the rib is located along the circumferential direction of the corrugated tube is tightened by the fastening member, the rib is difficult to come off from the small-diameter cylindrical portion.
[0015] (5) In any one of the wire harnesses from (1) to (4), the corrugated tube is fixed to the electric wire, the protector is fixed to the electric wire through the corrugated tube on the side of the first opening, and is not fixed to the electric wire on the side of the second opening. The electric wire may include a drawing and accommodating section in which the electric wire is drawn and accommodated with respect to the protector through the second opening. Thereby, since the electric wire is fixed to the protector through the corrugated tube on the side of the first opening, the drawing and accommodating operation of the drawing and accommodating section is smoothly performed on the side of the second opening.
[0016] In the wire harness of (6)(5), the accommodating portion has a passage portion having the second opening and an accommodating body that is connected to the passage portion and wider than the passage portion. The difference between the wire length in the accommodating portion in the state where the drawing and accommodating section is accommodated and the wire length in the accommodating portion in the state where the drawing and accommodating section is drawn out may be accommodated in the accommodating body. Thereby, the difference between the wire length in the accommodating portion in the state where the drawing and accommodating section is accommodated and the wire length in the accommodating portion in the state where the drawing and accommodating section is drawn out can be easily accommodated in the accommodating portion.
[0017] In the wire harness of (7)(6), the wire has a loop portion accommodated in the accommodating body, the accommodating portion has a pin penetrating the loop portion, and the loop portion around the pin in the state where the drawing and accommodating section is accommodated may be larger than the loop portion around the pin in the state where the drawing and accommodating section is drawn out. Thereby, the position of the loop portion of the wire can be regulated by the pin, and the drawing and accommodating operation of the drawing and accommodating section can be performed smoothly.
[0018] In the wire harness of (8)(7), the protector includes a main body portion having a bottom portion and a side wall portion and a lid portion serving as a lid of the main body portion. At an intersection where a first extending portion extending from an intermediate portion of the loop portion of the wire toward the first opening and a second extending portion extending from the intermediate portion of the loop portion toward the second opening intersect, the first extending portion may pass through the side of the main body portion rather than the second extending portion. Thereby, when the protector is arranged such that the main body portion is located vertically below the lid portion, the second extending portion of the wire overlaps vertically above the first extending portion. Thereby, even when the first extending portion and the second extending portion rub against each other at the intersection during the drawing and accommodating operation of the drawing and accommodating section, the drawing and accommodating operation is performed smoothly.
[0019] In the wire harness of any one of (9)(6) to (8), the end portion of the passage portion may have a shape in which the cross-sectional area gradually increases toward the second opening. Thereby, when the drawing and accommodating section is drawn and accommodated, it is less likely that the wire will be caught on the edge of the second opening.
[0020] (10) In any one of the wire harnesses from (5) to (9), the protector includes a vehicle fixing portion fixed to the vehicle body, the electric wire has an outer section located outside the second opening of the protector with the drawing and accommodating section accommodated in the protector, and the outer section of the electric wire may be fixed to a moving member movable with respect to the vehicle body. Thereby, the portion of the electric wire on the first opening side is fixed to the vehicle body together with the protector, and the outer section of the electric wire moves with respect to the vehicle body together with the moving member. For this reason, when the moving member moves, the drawing and accommodating section of the electric wire is drawn and accommodated with respect to the protector. Even in this case, since the drawing and accommodating section can be smoothly drawn and accommodated, it is possible to prevent the wire harness from interfering with the movement of the moving member.
[0021] (11) In any one of the wire harnesses from (5) to (10), the electric wire and the corrugated tube may be fixed by winding an adhesive tape on the second opening side of the rib. Thereby, since the fixing portion between the electric wire and the corrugated tube is on the second opening side of the rib, it is difficult for the corrugated tube to be displaced with respect to the electric wire during the drawing and accommodating operation.
[0022] (12) In any one of the wire harnesses from (1) to (11), the protruding dimension of the rib from the extending portion may be equal to or less than the height from the small-diameter cylindrical portion to the large-diameter cylindrical portion in the corrugated tube. Thereby, when the tightening member tightens the corrugated tube, it is possible to prevent the rib from pushing the small-diameter cylindrical portion, and thus excessive deformation of the corrugated tube is suppressed. Thereby, it is possible to prevent the corrugated tube from being excessively deformed and the locking between the rib and the corrugated tube from being weakened.
[0023] (13) In any one of the wire harnesses (1) to (12), in the extending direction of the electric wire, the rib may be the same as or smaller than the recess outside the small-diameter cylindrical portion. Thereby, when the fastening member fastens the corrugated tube, the rib is suppressed from pushing the corrugated tube, and thus excessive deformation of the corrugated tube is suppressed. Thereby, it is possible to suppress the corrugated tube from being excessively deformed and the locking between the rib and the corrugated tube from being weakened.
[0024] (14) In any one of the wire harnesses (1) to (13), the outer diameter of the electric wire is thinner than the inner diameter of the corrugated tube, and the corrugated tube may be deformed so that one end portion and the other end portion in the circumferential direction overlap each other in the radial direction, and the deformed state may be maintained by the fastening member. Thereby, a difference in diameter can be realized using the same type of corrugated tube. Since the corrugated tube is maintained in a deformed state in which one end portion and the other end portion in the circumferential direction overlap each other in the radial direction, there is less room for further deformation of the corrugated tube, and thus it is possible to suppress the rib from coming off the small-diameter cylindrical portion due to further deformation of the corrugated tube.
[0025] [Details of Embodiments of the Present Disclosure] A specific example of the wire harness of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, and is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
[0026] [Embodiment 1] Hereinafter, the wire harness according to Embodiment 1 will be described. FIG. 1 is a plan view showing a wire harness 10 according to Embodiment 1.

[0027] The wire harness 10 includes a protector 20, a wire 40, a corrugated tube 50, and a fastening member 60. The protector 20 and the corrugated tube 50 are attached to the wire 40. The protector 20 and the corrugated tube 50 overlap in a partial section along the extending direction of the wire 40. The fastening member 60 is provided at the overlapping portion of the protector 20 and the corrugated tube 50. The fastening member 60 keeps the protector 20 and the corrugated tube 50 in an overlapping state.
[0028] The protector 20 includes a housing portion 21 and an attachment portion 26. The protector 20 further includes a vehicle fixing portion 35. The protector 20 is, for example, a die-molded product made of resin.
[0029] The housing portion 21 has a first opening 22a and a second opening 23a. The first opening 22a is provided at a first end along the extending direction of the housing portion 21. The second opening 23a is provided at a second end along the extending direction of the housing portion 21. The housing portion 21 has a bent portion between the first opening 22a and the second opening 23a in a plan view.
[0030] The housing portion 21 of this example has a first passage portion 22, a second passage portion 23, and a housing body 24. The first passage portion 22 is provided at a first end along the extending direction of the housing portion 21. The first opening 22a is provided in the first passage portion 22. The first passage portion 22 has the first opening 22a. The second passage portion 23 is provided at a second end along the extending direction of the housing portion 21. The second opening 23a is provided in the second passage portion 23. The second passage portion 23 has the second opening 23a. The housing body 24 is connected to the first passage portion 22 and the second passage portion 23. The housing body 24 is provided between the first passage portion 22 and the second passage portion 23. The first passage portion 22 and the second passage portion 23 extend from the housing body 24 in different directions from each other. The second passage portion 23 is longer than the first passage portion 22. The second passage portion 23 may be the same as or shorter than the first passage portion 22.
[0031] The end of the first passage portion 22 on the side of the first opening 22a has a uniform cross-sectional area. The end of the first passage portion 22 on the side of the housing body 24 has a shape in which the cross-sectional area gradually increases toward the housing body 24.
[0032] The end of the second passage portion 23 on the side of the second opening 23a has a shape in which the cross-sectional area gradually increases toward the second opening 23a. The end of the second passage portion 23 on the side of the second opening 23a gradually widens toward the second opening 23a. The end of the second passage portion 23 on the side of the housing body 24 has a shape in which the cross-sectional area gradually increases toward the housing body 24. The middle portion of the second passage portion 23 has a uniform cross-sectional area.
[0033] The housing body 24 is wider than each of the first passage portion 22 and the second passage portion 23. The extending directions of the first passage portion 22 and the second passage portion 23 are provided to be orthogonal to each other. The housing body 24 bulges toward the inner peripheral side as compared with the case where the first passage portion 22 and the second passage portion 23 are extended until they intersect with each other.
[0034] The housing portion 21 has a pin 25. The pin 25 is provided on the housing body 24. The pin 25 regulates the path of the electric wire 40 in the housing body 24.
[0035] The mounting portion 26 is provided on the side of the first opening 22a of the housing portion 21. The mounting portion 26 has an extending portion 27 and a rib 30. The mounting portion 26 of this example further has a regulating portion 31.
[0036] The extending portion 27 extends along the extending direction of the electric wire 40 outside the corrugated tube 50. The extending portion 27 extends from the end of the first passage portion 22 toward the outside of the protector 20. The extending portion 27 is formed in an L shape having a bottom portion 28 and one side wall 29.
[0037] The rib 30 protrudes from the extending portion 27 toward the small-diameter cylindrical portion 51 of the corrugated tube 50. The rib 30 is formed so as to fit into the recess 54 on the outer side of the small-diameter cylindrical portion 51 of the corrugated tube 50. The number, position, shape, size, etc. of the rib 30 are not particularly limited and can be appropriately set within a range where it can fit into the recess 54 of the corrugated tube 50.
[0038] Regarding the number of the ribs 30, here only one rib 30 is formed. Therefore, the rib 30 is provided only at one location along the extending direction of the extending portion 27. Also, the rib 30 is provided only at one location along the circumferential direction of the electric wire 40. A plurality of ribs 30 may be formed along the extending direction of the extending portion 27. The ribs 30 may be formed in a plurality of parts along the circumferential direction of the electric wire 40 of the extending portion 27.
[0039] Regarding the position of the rib 30, here the rib 30 is formed at the intermediate portion along the extending direction of the extending portion 27. The rib 30 is formed across the bottom portion 28 and the side wall 29 of the extending portion 27.
[0040] Regarding the shape of the rib 30, the rib 30 is formed such that the tip end portion is thinner than the base end portion on the side connected to the bottom portion 28 and the side wall 29. Here, the rib 30 is formed such that the cross-section orthogonal to the circumferential direction has a triangular shape. The tip end portion of the rib 30 facing the outer surface of the small-diameter cylindrical portion 51 is rounded. Thereby, even if the tip end portion of the rib 30 comes into contact with the small-diameter cylindrical portion 51, it is difficult to damage the small-diameter cylindrical portion 51.
[0041] Regarding the size of the rib 30, here the height dimension of the rib 30 is larger than the width dimension of the base end portion (the dimension along the extending direction of the extending portion 27).
[0042] The restricting portion 31 is provided outside the extending portion 27. The restricting portion 31 restricts the position of the fastening member 60. The restricting portion 31 has a band insertion portion 32 and a rib portion 34.
[0043] The band insertion portion 32 allows the binding band 60 as the tightening member 60 to be inserted therethrough. The band insertion portion 32 has an opposing portion that opposes the extending portion 27 and a pair of connecting portions that connect the opposing portion and the extending portion 27. The portion surrounded by the extending portion 27, the opposing portion, and the pair of connecting portions serves as the insertion hole 33.
[0044] The band insertion portion 32 is provided on the outer surface of the side wall 29 in the extending portion 27. The axial direction of the insertion hole 33 is parallel to the height direction of the side wall 29. Thereby, the rib 30 and the band insertion portion 32 can be formed by a simple mold that is vertically punched along the axial direction of the insertion hole 33.
[0045] A rib 30 is provided at the same position as the band insertion portion 32 along the extending direction of the extending portion 27. In the extending direction of the extending portion 27, the rib 30 is smaller than the insertion hole 33. In the extending direction of the extending portion 27, the center of the rib 30 is at the same position as the center of the insertion hole 33.
[0046] The rib portion 34 is provided on the tip side of the extending portion 27 with respect to the insertion hole 33. Here, the rib portion 34 is provided at the tip of the extending portion 27. The rib portion 34 may be provided around the entire periphery of the L-shaped extending portion 27. Here, a part of the rib portion 34 also serves as the connecting portion of the band insertion portion 32. The rib portion 34 is provided adjacent to the insertion hole 33. The protruding dimension of the rib portion 34 from the extending portion 27 may be any dimension that can prevent the tightening member 60 from getting over the rib portion 34. For example, it may be the same as or larger than the thickness of the band 61. The protruding dimension of the rib portion 34 from the extending portion 27 may be about the same as the distance between the outer surface of the extending portion 27 and the inner surface of the opposing portion.
[0047] The vehicle fixing portion 35 is a portion for fixing the protector 20 to the vehicle. Here, the vehicle fixing portion 35 is a clip 35. The vehicle fixing portion 35 may be a screw hole or the like. Here, two vehicle fixing portions 35 are provided on the side of the accommodating portion 21.
[0048] The protector 20 has a main body portion 36 and a lid portion 37. The main body portion 36 has a part of the accommodating portion 21, a mounting portion 26, and a vehicle fixing portion 35. The lid portion 37 serves as a lid for the main body portion 36. The lid portion 37 has the other part of the accommodating portion 21. The accommodating portion 21 is constituted by the main body portion 36 and the lid portion 37. The mounting portion 26 is provided on the main body portion 36. The part of the accommodating portion 21 provided on the main body portion 36 is formed in a gutter shape having a bottom portion 36a and a pair of side walls 36b, 36c. The upper part of the part of the accommodating portion 21 provided on the main body portion 36 is open. The upper opening of the part of the accommodating portion 21 provided on the main body portion 36 is closed by the lid portion 37. The pin 25 is provided on the main body portion 36. A pin hole 25h for passing the pin 25 is formed in the lid portion 37. The pin 25 penetrates into the lid portion 37. Thereby, the pin 25 extends from the inner surface of the bottom of the main body portion 36 to the inner surface of the lid portion 37.
[0049] The main body portion 36 and the lid portion 37 are connected via a hinge 38. The hinge 38 is provided on the side wall 36b. The hinge 38 is provided on the portion of the side wall 36b located in the second passage portion 23 and the portion of the accommodating main body 24 that extends straight from the second passage portion 23. The main body portion 36 and the lid portion 37 can be opened and closed via the hinge 38.
[0050] The main body portion 36 and the lid portion 37 can be locked by a locking portion 39a and a mating locking portion 39b in the closed position. The locking portion 39a is provided on the main body portion 36, and the mating locking portion 39b is provided on the lid portion 37. A plurality of sets of the locking portion 39a and the mating locking portion 39b are provided. Here, the sets of the locking portion 39a and the mating locking portion 39b are provided on the side wall 36c where the hinge 38 is not provided. Also, the sets of the locking portion 39a and the mating locking portion 39b are provided on the portion of the side wall 36b where the hinge 38 is provided and located in the first passage portion 22 and the portion of the accommodating main body 24 that extends straight from the second passage portion 23.
[0051] The protector 20 is an integrally molded product formed by die molding so as to have a main body portion 36, a lid portion 37, and a hinge 38. The protector 20 may be such that the main body portion 36 and the lid portion 37 are separate parts without having the hinge 38. The main body portion 36 and the lid portion 37 may be separately die molded. In this case, locking portions 39a and mating locking portions 39b may be provided at the portion of the hinge 38 in place of the hinge 38 on the main body portion and the lid portion.
[0052] The bottom portion 28 of the extending portion 27 is connected to the bottom portion 36a of the main body portion 36. The side wall 29 of the extending portion 27 is connected to the side wall 36b of the main body portion 36. The main body portion 36 has a side wall 36b that is not present in the extending portion 27. In the path that bends from the first passage portion 22 toward the second passage portion 23, the side wall 36b is located on the outer peripheral side and the side wall 36c is located on the inner peripheral side. In the path that bends from the first passage portion 22 toward the second passage portion 23, the side wall 36c bulges on the inner peripheral side, expanding the housing main body 24. The side wall 29 of the extending portion 27 may be provided so as to be connected to the side wall 36c of the main body portion 36.
[0053] The bottom portion 36a of the first passage portion 22 and the bottom portion 28 of the portion where the rib 30 is provided are displaced in the height direction. The bottom portion 28 of the portion where the rib 30 is provided is higher than the bottom portion 36a of the first passage portion 22. Thereby, it is suppressed that the convex strip portion 34 and the binding band 60 outside the bottom portion 28 project largely outside the protector 20. A step is formed between the bottom portion 36a of the first passage portion 22 and the bottom portion 28 of the portion where the rib 30 is provided. In order to eliminate the step, the extending portion 27 has a portion that extends obliquely from the first opening 22a of the first passage portion 22.
[0054] The side wall 36c on the side where the hinge 38 is not provided in the second passage portion 23 bulges outward, expanding the second passage portion 23. At the end portion on the second opening 23a side of the second passage portion 23, the extending direction of the side wall 36c and the extending direction of the side wall 36b intersect each other. The width dimension of the bottom portion of the second passage portion 23 gradually increases toward the second opening 23a.
[0055] The protector 20 is fixed to the electric wire 40 via the corrugated tube 50 on the side of the first opening 22a. The protector 20 is not fixed to the electric wire 40 on the side of the second opening 23a.
[0056] The electric wire 40 passes through the accommodating portion 21 via the first opening 22a and the second opening 23a. At least one electric wire 40 is provided. Here, a plurality of electric wires 40 are provided. The plurality of electric wires 40 may be bundled so as to approximate a round cross-section. One end portion of the electric wire 40 extends out of the accommodating portion 21 from the first opening 22a. The other end portion of the electric wire 40 extends out of the accommodating portion 21 from the second opening 23a. One end portion and the other end portion of the electric wire 40 are respectively connected to the device 90 via a connector 48 or the like.
[0057] FIG. 6 is a plan view showing a state in which the electric wire 40 is accommodated in the protector 20. FIG. 7 is a plan view showing a state in which the electric wire 40 is drawn out from the protector 20.
[0058] In this example, the electric wire 40 is drawn out and accommodated in the protector 20. The electric wire 40 includes a drawing and accommodating section 41. The drawing and accommodating section 41 is a section that is drawn out and accommodated in the protector 20 through the second opening 23a. The difference between the length of the electric wire in the accommodating portion 21 in the state where the drawing and accommodating section 41 is accommodated (the state shown in FIG. 6) and the length of the electric wire in the accommodating portion 21 in the state where the drawing and accommodating section 41 is drawn out (the state shown in FIG. 7) is accommodated in the accommodating main body 24.
[0059] The electric wire 40 has an outer section 42. The outer section 42 is a section of the electric wire 40 that is located outside the second opening 23a of the protector 20 in the state where the drawing and accommodating section 41 is accommodated in the protector 20. The outer section 42 of the electric wire 40 is fixed to a moving member 80 that is movable with respect to the vehicle body 82. By moving the outer section 42 together with the moving member 80, the drawing and accommodating section 41 is drawn out and accommodated in the protector 20.
[0060] The electric wire 40 has a loop portion 43. The electric wire 40 forms the loop portion 43 within the accommodating portion 21. The loop portion 43 is accommodated in the accommodating main body 24. Along with the drawing and accommodating operation of the drawing and accommodating section 41, the size of the loop portion 43 changes.
[0061] Specifically, the pin 25 penetrates the loop portion 43. The loop portion 43 around the pin 25 in the state where the drawing and accommodating section 41 is accommodated (the state shown in FIG. 6) is larger than the loop portion 43 around the pin 25 in the state where the drawing and accommodating section 41 is drawn out (the state shown in FIG. 7).
[0062] The tip of the pin 25 fits into the pin hole 25h of the lid portion 37. For this reason, the pin 25 extends from the inner surface of the bottom portion 36a of the main body portion 36 to a position beyond the inner surface of the lid portion 37. For this reason, even if the electric wire 40 contacts the pin 25 and presses the lid portion 37 during the drawing and accommodating operation, it is suppressed that the electric wire 40 is caught between the tip of the pin 25 and the inner surface of the lid portion 37.
[0063] The portion of the electric wire 40 from the middle portion of the loop portion 43 toward the first opening 22a is defined as the first extending portion 44. Also, the portion of the loop portion 43 from the middle portion toward the second opening 23a is defined as the second extending portion 45. The first extending portion 44 and the second extending portion 45 intersect with each other to form an intersection portion 46. By the electric wire 40 having the loop portion 43, an intersection portion 46 is provided on the electric wire 40. At the intersection portion 46, the first extending portion 44 passes through the side of the main body portion 36 rather than the second extending portion 45.
[0064] The second passage portion 23 may have a length corresponding to the drawing and accommodating section 41. Thereby, the drawing and accommodating section 41 can extend straight within the protector 20. Also, even when the drawing and accommodating section 41 is maximally accommodated in the accommodating portion 21, it does not reach the intersection portion 46.
[0065] In the lead-out storage section 41 of the electric wire 40, a twist tube 71 may be provided. The twist tube 71 is a fiber protection member such as a fabric. The twist tube 71 has flexibility. The twist tube 71 is superior in bendability to the corrugated tube 50. One end portion of the twist tube 71 may be housed within the protector 20 in a state where the lead-out storage section 41 is pulled out, as shown in FIG. 7. One end portion of the twist tube 71 may be located outside the protector 20 in a state where the lead-out storage section 41 is pulled out. In the examples shown in FIGS. 6 and 7, one end portion of the twist tube 71 does not reach the loop portion 43. One end portion of the twist tube 71 may reach the loop portion 43. The twist tube 71 may be provided on the first extending portion 44 and the second extending portion 45 that cross each other at the crossing portion 46. The other end portion of the twist tube 71 may reach, for example, a seat protector 72 described later.
[0066] The corrugated tube 50 includes a small-diameter cylindrical portion 51 and a large-diameter cylindrical portion 52. The corrugated tube 50 is, for example, a molded product made of a resin such as PP (polypropylene). The small-diameter cylindrical portion 51 and the large-diameter cylindrical portion 52 are continuously arranged alternately. The central axis of the small-diameter cylindrical portion 51 coincides with the central axis of the large-diameter cylindrical portion 52. The small-diameter cylindrical portion 51 and the large-diameter cylindrical portion 52 extend concentrically with respect to one central axis. The corrugated tube 50 covers at least the portion of the electric wire 40 that extends along the attachment portion 26. In the corrugated tube 50, a connecting wall 53 connects the thinnest portion of the small-diameter cylindrical portion 51 and the thickest portion of the large-diameter cylindrical portion 52. The connecting wall 53 extends radially outward from the thinnest portion of the small-diameter cylindrical portion 51 toward the thickest portion of the large-diameter cylindrical portion 52. The portion surrounded by the thinnest portion of the small-diameter cylindrical portion 51 and a pair of connecting walls 53 sandwiching the said portion is the recess 54 outside the small-diameter cylindrical portion 51 in the corrugated tube 50. The rib 30 is fitted in the said recess 54. When the corrugated tube 50 is axially pulled, the rib 30 catches on the connecting wall 53 on the pulled side among the pair of connecting walls 53.
[0067] The protruding dimension from the extending portion 27 of the rib 30 is equal to or less than the height from the small-diameter cylindrical portion 51 to the large-diameter cylindrical portion 52. That is, the protruding dimension from the extending portion 27 of the rib 30 is equal to or less than the height of the recess 54. The height from the small-diameter cylindrical portion 51 to the large-diameter cylindrical portion 52 is the difference between the radius of the small-diameter cylindrical portion 51 and the radius of the large-diameter cylindrical portion 52. In the extending direction of the electric wire 40, the dimension of the rib 30 is equal to or less than the dimension of the small-diameter cylindrical portion 51.
[0068] A slit 55 is formed in the corrugated tube 50. The slit 55 is formed over the entire length along the axial direction of the corrugated tube 50. The corrugated tube 50 can be attached to the electric wire 40 from the side by opening the edge portions sandwiching the slit 55.
[0069] The tightening member 60 is wound around the corrugated tube 50 and the attachment portion 26. The tightening member 60 tightens the corrugated tube 50 and the attachment portion 26. The tightening member 60 is provided at the same position as the rib 30 along the extending direction of the extending portion 27.
[0070] In the corrugated tube 50, a part along the circumferential direction of the electric wire 40 is covered by the attachment portion 26. In the corrugated tube 50, another part along the circumferential direction of the electric wire 40 is tightened toward the attachment portion 26 by the tightening member 60.
[0071] The fastening member 60 is a binding band 60. The binding band 60 has a band 61 and a band fixing portion 62. The band 61 is wound around the corrugated tube 50 and the attachment portion 26. The band fixing portion 62 is provided at the base end portion of the band 61. The band fixing portion 62 fixes the tip end portion of the band 61. The band fixing portion 62 has a base 63 and a through hole 64. The base 63 is formed in, for example, a rectangular parallelepiped shape. The band 61 extends from the outer surface of the base 63. The through hole 64 penetrates the base 63. The tip end portion of the band 61 is passed through the through hole 64 and fixed. For example, a locking convex portion is provided on the inner surface of the through hole 64. A plurality of concave portions are formed in the band 61. When the tip end portion of the band 61 is passed through the through hole 64, the locking convex portion selectively locks to any one of the plurality of concave portions.
[0072] The band 61 passes through the insertion hole 33 of the band insertion portion 32. Thereby, the position of the band 61 along the extending direction of the extending portion 27 is regulated. The base 63 is formed larger than the insertion hole 33 and is made non-insertable through the insertion hole 33. Thereby, the base 63 is caught by the peripheral edge portion of the insertion hole 33 of the band insertion portion 32, and the binding band 60 is suppressed from rotating in the circumferential direction of the electric wire 40.
[0073] The width dimension of the band 61 is equal to or greater than the width dimension of the rib 30. The width dimension of the band 61 may be larger than the interval between adjacent large-diameter cylindrical portions 52. In this case, the band 61 tightens the corrugated tube 50 from the outside of the large-diameter cylindrical portion 52 without fitting into the recess 54 outside the small-diameter cylindrical portion 51. The width dimension of the band 61 may be equal to or less than the interval between adjacent large-diameter cylindrical portions 52. In this case, the band 61 may fit into the recess 54 outside the small-diameter cylindrical portion 51 and tighten the small-diameter cylindrical portion 51 or the connecting wall 53.
[0074] A rib portion 34 is provided on the tip end side of the extending portion 27 rather than the band 61. Thereby, when the band 61 is displaced to the tip end side of the extending portion 27, it is caught by the rib portion 34, and further displacement is suppressed. Thereby, the portion of the band 61 that tightens the bottom portion 28 of the extending portion 27 is suppressed from coming off the outside of the protector 20 along the extending direction of the extending portion 27.
[0075] The end of the corrugated tube 50 is located on the second opening 23a side rather than the clamping member 60. The end of the corrugated tube 50 may be accommodated in the accommodating portion 21. The end of the corrugated tube 50 may be accommodated near the first opening 22a. Preferably, the end of the corrugated tube 50 does not reach the loop portion 43. The end of the corrugated tube 50 is accommodated in the first passage portion 22.
[0076] The electric wire 40 and the corrugated tube 50 are fixed by winding the adhesive tape 70. The electric wire 40 has a tube fixing portion 47 fixed to the corrugated tube 50. Thereby, the rotation of the corrugated tube 50 around the electric wire 40 is suppressed. A portion (for example, the end portion) of the corrugated tube 50 that is accommodated in the accommodating portion 21 may be fixed to the electric wire 40 by the adhesive tape 70. Thereby, the electric wire 40 and the corrugated tube 50 can be fixed near the rib 30. The adhesive tape 70 is wound around the electric wire 40 and the corrugated tube 50. The adhesive tape 70 is provided at a position avoiding the rib 30. Thereby, it is suppressed that the outer surface of the corrugated tube 50 is hidden by the adhesive tape 70 at the position of the rib 30.
[0077] The tube fixing portion 47 is provided on the second opening 23a side rather than the rib 30. The tube fixing portion 47 is provided on the first opening 22a side rather than the loop portion 43. The loop portion 43 is provided between the tube fixing portion 47 and the drawing and accommodating section 41.
[0078] The protector 20 and the electric wire 40 are fixed via the attachment portion 26, the corrugated tube 50, the clamping member 60, and the adhesive tape 70. The electric wire 40 and the corrugated tube 50 are fixed by the adhesive tape 70. The protector 20 and the corrugated tube 50 are fixed by the attachment portion 26, the recess 54 outside the small-diameter tube portion 51, and the clamping member 60.
[0079] The rib 30 fits into a recess 54 formed between two large-diameter cylindrical portions 52 on the outside of the small-diameter cylindrical portion 51. When the corrugated tube 50 is pulled in the extending direction, the rib 30 catches on a connecting wall 53 that connects the outer peripheral surface of the small-diameter cylindrical portion 51 and the outer peripheral surface of the large-diameter cylindrical portion 52. At this time, by the tightening member 60 tightening the extending portion 27, the electric wire 40, and the corrugated tube 50, the electric wire 40 presses the corrugated tube 50 toward the bottom portion 28. As a result, even when the connecting wall 53 is pushed by the rib 30, deformation of the corrugated tube 50 such that the recess 54 becomes smaller is suppressed, and the rib 30 is likely to be kept in a state of fitting into the recess 54.
[0080] <Regarding the operation that occurs in the wire harness> The wire harness 10 is attached at a location involving movement in a vehicle. Specifically, the protector 20 is fixed to the vehicle body. The portion of the electric wire 40 that extends from the second opening 23a of the protector 20 is fixed to a moving member. The moving member is movably attached to the vehicle body. The moving member is, for example, a vehicle seat 80. The seat 80 has a lower frame 81 that is movably attached to a floor panel 82 via a rail 83. For example, a seat protector 72 is provided on the portion of the electric wire 40 that is fixed to the seat 80. The portion of the electric wire 40 that is fixed to the seat protector 72 is movable relative to the vehicle body 82 together with the seat 80.
[0081] As the seat 80 moves, the lead-out storage section 41 of the electric wire 40 is led out and stored with respect to the protector 20. Specifically, the seat 80 can reciprocate between a position P1 close to the protector 20 (the solid line position in FIG. 1) and a position P2 farther from the protector 20 than the position P1 (the two-dot chain line position in FIG. 1). When the seat 80 is located at the position P1, the lead-out storage section 41 is in a state of being maximally stored in the protector 20 (the state in FIG. 6). When the seat 80 moves from the position P1 toward the position P2, the lead-out storage section 41 is sequentially led out from the protector 20. When the seat 80 is located at the position P2, the lead-out storage section 41 is in a state of being maximally led out from the protector 20 (the state in FIG. 7). When the seat 80 moves from the position P2 toward the position P1, the lead-out storage section 41 is sequentially stored in the protector 20. When the seat 80 reaches the position P1, the lead-out storage section 41 returns to the state of being maximally stored in the protector 20 (the state in FIG. 6).
[0082] With the protector 20 fixed to the vehicle body 82 by the vehicle fixing portion 35, the portions of the electric wire 40 extending from the first opening 22a and the second opening 23a can be pulled. For example, in the wire harness 10, after the protector 20 is first fixed to the vehicle, when one end and the other end of the electric wire 40 are routed for connection to a device 90 or the like, the one end and the other end of the electric wire 40 can be pulled. Also, when the outer section 42 of the electric wire 40 extending from the second opening 23a moves with the movement of the seat 80, the other end of the electric wire 40 can be pulled. In these cases, the portion of the corrugated tube 50 attached to the protector 20 may be pulled by the electric wire 40. Even in this case, since the rib 30 of the protector 20 fits into the recess outside the small-diameter cylindrical portion 51 of the corrugated tube 50, the corrugated tube 50 is not easily detached from the protector 20. Also, even when the outer section 42 reciprocates with the seat 80, since the electric wire 40 is fixed to the attachment portion 26 via the corrugated tube 50, the end of the portion extending outside the first opening 22a and the connector 48 connected thereto are prevented from being pulled toward the protector 20 side. Thereby, it is suppressed that the end of the electric wire 40 comes out of the connector 48 or the connector 48 comes out of the device 90 or the mating connector.
[0083] <Modification example> FIGS. 8 and 9 are cross-sectional views showing a wire harness 110 according to a modification example. FIG. 8 corresponds to the cross-section of FIG. 3, and FIG. 9 corresponds to the longitudinal section of FIG. 2.
[0084] The outer diameter of the wire 40 is smaller than the inner diameter of the corrugated tube 50. When there are a plurality of wires 40, the outer diameter of the wire 40 is the outer diameter of the wire 40 bundle. In the present disclosure, the other end of the wire 40 is connected to the device 90 of the seat 80. The number of wires 40 is determined according to the number, type, etc. of the devices 90 in the seat 80. The device 90 in the seat 80 may include at least one optional device that can be selected by the user. Depending on whether the optional device is adopted or not, the number of wires 40 changes. When the adoption of the optional device is small, the number of wires 40 decreases, and the outer diameter of the wire 40 (the outer diameter of the wire 40 bundle) becomes thinner. When the adoption of the optional device is large, the number of wires 40 increases, and the outer diameter of the wire 40 (the outer diameter of the wire 40 bundle) becomes thicker. The outer diameter of the wire 40 (the outer diameter of the wire 40 bundle) may be, for example, the same as or smaller than the width dimension of the bottom portion 28.
[0085] The corrugated tube 50 has the same size as the corrugated tube 50 of Embodiment 1. The corrugated tube 50 is deformed so that one end portion and the other end portion in the circumferential direction overlap each other in the radial direction. The one end portion and the other end portion in the circumferential direction are the portions at both edges of the slit 55. As a result, the corrugated tube 50 is shrunk. However, when the corrugated tube 50 shrinks, it may be deformed into a shape (non-circular shape) other than the example shown in FIG. 9. For example, when the direction sandwiched between the fastening member 60 and the extending portion 27 is defined as the first direction and the direction orthogonal to this is defined as the second direction, the corrugated tube 50 may be deformed into an oval shape that is longer in the second direction than in the first direction. The corrugated tube 50 may not be in close contact with the wire 40 bundle and may have a gap in a portion where neither the fastening member 60 nor the adhesive tape 70 is provided.
[0086] The overlapping portion of the corrugated tube 50 is provided at a position avoiding the rib 30 along the circumferential direction of the electric wire 40, and it is preferable that the deformation of the portion of the corrugated tube 50 that comes into contact with the rib 30 is suppressed. Thereby, even when the corrugated tube 50 is contracted, the corrugated tube 50 and the rib 30 can come into good contact with each other, and the engaged state between the rib 30 and the corrugated tube 50 is likely to be an appropriate state. The overlapping portion of the corrugated tube 50 is preferably, for example, at a portion that comes into contact with the fastening member 60.
[0087] The deformed state of the corrugated tube 50 is maintained by the fastening member 60. When the corrugated tube 50 is fixed to the electric wire 40 by the adhesive tape 70, if it is pre-contracted near the fastening member 60, it is easier to be kept in the contracted shape by the adhesive tape 70 also at the position of the fastening member 60, and it is easier to be contracted into a predetermined shape.
[0088] <Effects, etc.> According to the wire harnesses 10 and 110 configured as described above, a part along the circumferential direction of the corrugated tube 50 is covered by the mounting portion 26, and the other part is tightened toward the mounting portion 26 by the fastening member 60, so that the rib 30 of the mounting portion 26 is kept in a state of being fitted into the recess outside the small-diameter cylindrical portion 51. Instead of the mounting portion 26 covering the entire circumference of the corrugated tube 50, since the fastening member 60 is provided at a portion of the corrugated tube 50 that is not covered by the mounting portion 26, the mounting portion 26 and the fastening member 60 can cope with corrugated tubes 50 of various diameters.
[0089] Also, the rib 30 is provided only at one location along the extending direction of the extending portion 27. Thereby, even for a plurality of types of corrugated tubes 50 having different intervals of the small-diameter cylindrical portions 51 along the extending direction, the rib 30 can easily fit into the recess outside the small-diameter cylindrical portion 51. If there are ribs 30 at a plurality of locations along the extending direction of the extending portion 27, it may be difficult to cope with a corrugated tube 50 in which the interval of the small-diameter cylindrical portions 51 does not match the interval of the ribs 30.
[0090] Further, the attachment portion 26 is provided outside the extending portion 27 and has a restricting portion 31 that restricts the position of the fastening member 60. Thereby, it becomes difficult for the fastening member 60 to be displaced with respect to the attachment portion 26.
[0091] Further, the fastening member 60 is provided at the same position as the rib 30 along the extending direction of the extending portion 27. Thereby, since the portion on the side opposite to the side where the rib 30 is located along the circumferential direction of the corrugated tube 50 is fastened by the fastening member 60, the rib 30 is unlikely to come off from the small-diameter cylindrical portion 51.
[0092] Further, the corrugated tube 50 is fixed to the electric wire 40, and the protector 20 is fixed to the electric wire 40 via the corrugated tube 50 on the side of the first opening 22a and is not fixed to the electric wire 40 on the side of the second opening 23a. The electric wire 40 includes a drawing and accommodating section 41 that is drawn and accommodated with respect to the protector 20 through the second opening 23a. Thereby, since the electric wire 40 is fixed to the protector 20 via the corrugated tube 50 on the side of the first opening 22a, the drawing and accommodating operation of the drawing and accommodating section 41 is smoothly performed on the side of the second opening 23a.
[0093] Further, the accommodating portion 21 has a second passage portion 23 having the second opening 23a and an accommodating main body 24 that is connected to the second passage portion 23 and is wider than the second passage portion 23. The difference between the length of the electric wire in the accommodating portion 21 in the state where the drawing and accommodating section 41 is accommodated and the length of the electric wire in the accommodating portion 21 in the state where the drawing and accommodating section 41 is drawn out is accommodated in the accommodating main body 24. Thereby, the difference between the length of the electric wire in the accommodating portion 21 in the state where the drawing and accommodating section 41 is accommodated and the length of the electric wire in the accommodating portion 21 in the state where the drawing and accommodating section 41 is drawn out can be easily accommodated in the accommodating portion 21.
[0094] Further, the electric wire 40 has a loop portion 43 housed in the housing body 24, the housing portion 21 has a pin 25 passing through the loop portion 43, and the loop portion 43 around the pin 25 in the state where the drawing housing section 41 is housed is larger than the loop portion 43 around the pin 25 in the state where the drawing housing section 41 is drawn out. Thereby, the position of the loop portion 43 of the electric wire 40 can be regulated by the pin 25, and the drawing housing operation of the drawing housing section 41 can be smoothly performed.
[0095] Further, the protector 20 includes a main body portion 36 having a bottom portion and a side wall portion, and a lid portion 37 serving as a lid of the main body portion 36. At an intersection portion 46 where a first extending portion 44 extending from an intermediate portion of the loop portion 43 of the electric wire 40 toward the first opening 22a and a second extending portion 45 extending from the intermediate portion of the loop portion 43 toward the second opening 23a intersect, the first extending portion 44 passes through the side of the main body portion 36 more than the second extending portion 45. Thereby, when the protector 20 is arranged such that the main body portion 36 is positioned vertically below the lid portion 37, the second extending portion 45 of the electric wire 40 overlaps vertically above the first extending portion 44. Thereby, even when the first extending portion 44 and the second extending portion 45 rub against each other at the intersection portion 46 during the drawing housing operation of the drawing housing section 41, the drawing housing operation can be smoothly performed.
[0096] Further, the end portion of the second passage portion 23 has a shape in which the cross-sectional area gradually increases toward the second opening 23a. Thereby, when the drawing housing section 41 is drawn and housed, it becomes difficult for the electric wire 40 to be caught by the edge portion of the second opening 23a.
[0097] Further, the protector 20 includes a vehicle fixing portion 35 fixed to the vehicle body. The electric wire 40 has an outer section 42 located outside the second opening 23a of the protector 20 with the drawing and accommodating section 41 accommodated in the protector 20. The outer section 42 of the electric wire 40 is fixed to a moving member 80 movable relative to the vehicle body 82. Thereby, the portion of the electric wire 40 on the side of the first opening 22a is fixed to the vehicle body 82 together with the protector 20, and the outer section 42 of the electric wire 40 moves relative to the vehicle body 82 together with the moving member 80. For this reason, when the moving member 80 moves, the drawing and accommodating section 41 of the electric wire 40 is drawn and accommodated with respect to the protector 20. Even in this case, since the drawing and accommodating section 41 can be smoothly drawn and accommodated, it is suppressed that the wire harness 10 obstructs the movement of the moving member 80.
[0098] Further, the electric wire 40 and the corrugated tube 50 are fixed by winding an adhesive tape 70 on the side of the second opening 23a rather than the rib 30. Thereby, since the fixing portion of the electric wire 40 and the corrugated tube 50 is on the side of the second opening 23a rather than the rib 30, it is difficult for the corrugated tube 50 to be displaced relative to the electric wire 40 during the drawing and accommodating operation.
[0099] Further, the protruding dimension from the extending portion 27 of the rib 30 is equal to or less than the height from the small-diameter cylindrical portion 51 to the large-diameter cylindrical portion 52 of the corrugated tube 50. Thereby, when the tightening member 60 tightens the corrugated tube 50, it is suppressed that the rib 30 presses the small-diameter cylindrical portion 51, and thus excessive deformation of the corrugated tube 50 is suppressed. Thereby, it is possible to suppress that the corrugated tube 50 is excessively deformed and the locking between the rib 30 and the corrugated tube 50 is weakened.
[0100] Further, in the extending direction of the electric wire 40, the rib 30 is the same as or smaller than the recess outside the small-diameter cylindrical portion 51. Thereby, when the tightening member 60 tightens the corrugated tube 50, it is suppressed that the rib 30 presses the corrugated tube 50, and thus excessive deformation of the corrugated tube 50 is suppressed. Thereby, it is possible to suppress that the corrugated tube 50 is excessively deformed and the locking between the rib 30 and the corrugated tube 50 is weakened.
[0101] Also, according to the wire harness 110, the outer diameter of the electric wire 40 is thinner than the inner diameter of the corrugated tube 50, and the corrugated tube 50 is deformed such that one end portion and the other end portion in the circumferential direction overlap each other in the radial direction, and the deformed state is maintained by the tightening member 60. Thereby, a difference in diameter can be realized using the same type of corrugated tube 50. Since the corrugated tube 50 is maintained in a deformed state such that one end portion and the other end portion in the circumferential direction overlap each other in the radial direction, there is less room for further deformation of the corrugated tube 50, and thus, it is possible to suppress the rib 30 from coming off from the small-diameter cylindrical portion 51 due to further deformation of the corrugated tube 50.
[0102] [Appendix] So far, the rib 30 has been described as being provided only at one location along the extending direction of the extending portion 27, but this is not an essential configuration. For example, the rib 30 may be provided at a plurality of locations along the extending direction of the extending portion 27.
[0103] Also so far, the mounting portion 26 has been described as having a restricting portion 31 provided outside the extending portion 27 to restrict the position of the tightening member 60, but this is not an essential configuration. For example, the mounting portion 26 may not have the restricting portion 31.
[0104] Also so far, the tightening member 60 has been described as being provided at the same position as the rib 30 along the extending direction of the extending portion 27, but this is not an essential configuration. For example, the tightening member 60 may be provided at a position different from the rib 30 along the extending direction of the extending portion 27.
[0105] Heretofore, the corrugated tube 50 has been fixed to the electric wire 40, and the protector 20 has been fixed to the electric wire 40 via the corrugated tube 50 on the side of the first opening 22a and has not been fixed to the electric wire 40 on the side of the second opening 23a. The electric wire 40 has been described as including a lead-out accommodation section 41 that is led out and accommodated with respect to the protector 20 through the second opening 23a, but this is not an essential configuration. For example, the electric wire 40 may not have the lead-out accommodation section 41, and the protector 20 may be fixed to the electric wire 40 also on the side of the second opening 23a.
[0106] Heretofore, the accommodating portion 21 has been described as having a second passage portion 23 having the second opening 23a and an accommodation main body 24 that is connected to the second passage portion 23 and is wider than the second passage portion 23, and the difference between the length of the electric wire in the accommodating portion 21 when the lead-out accommodation section 41 is accommodated and the length of the electric wire in the accommodating portion 21 when the lead-out accommodation section 41 is led out is described as being accommodated in the accommodation main body 24, but this is not an essential configuration. For example, the accommodating portion 21 may not have the second passage portion 23.
[0107] Heretofore, the electric wire 40 has been described as having a loop portion 43 that is accommodated in the accommodation main body 24, the accommodating portion 21 has been described as having a pin 25 that penetrates the loop portion 43, and the loop portion 43 around the pin 25 when the lead-out accommodation section 41 is accommodated is described as being larger than the loop portion 43 around the pin 25 when the lead-out accommodation section 41 is led out, but this is not an essential configuration. For example, the electric wire 40 may not have the loop portion 43. For example, the electric wire 40 may have a bent portion in the accommodating portion 21, and the path length of the bent portion may change between the state where the lead-out accommodation section 41 is accommodated and the state where the lead-out accommodation section 41 is led out.
[0108] Also, heretofore, the protector 20 has included a main body portion 36 having a bottom portion and side wall portions, and a lid portion 37 serving as a lid for the main body portion 36. At an intersection portion 46 where a first extending portion 44 extending from an intermediate portion of a loop portion 43 of the electric wire 40 toward a first opening 22a and a second extending portion 45 extending from the intermediate portion of the loop portion 43 toward a second opening 23a intersect, the first extending portion 44 has been described as passing through the side of the main body portion 36 rather than the second extending portion 45. However, this is not an essential configuration. For example, at the intersection portion 46, the first extending portion 44 may pass through the side of the lid portion 37 rather than the second extending portion 45.
[0109] Also, heretofore, the end portion of the second passage portion 23 has been described as having a shape in which the cross-sectional area gradually increases toward the second opening 23a. However, this is not an essential configuration. For example, the end portion of the second passage portion 23 may have a uniform cross-sectional area toward the second opening 23a.
[0110] Also, heretofore, the protector 20 has included a vehicle fixing portion 35 fixed to the vehicle body 82. The electric wire 40 has an outer section 42 located outside the second opening 23a of the protector 20 in a state where a lead accommodation section 41 is accommodated in the protector 20. The outer section 42 of the electric wire 40 has been described as being fixed to a moving member 80 movable with respect to the vehicle body 82. However, this is not an essential configuration. For example, the outer section 42 of the electric wire 40 may be fixed to an opening / closing member that can be opened and closed with respect to the vehicle body 82.
[0111] Also, heretofore, the electric wire 40 and the corrugated tube 50 have been described as being fixed by winding an adhesive tape 70 on the side closer to the second opening 23a than the rib 30. However, this is not an essential configuration. For example, the electric wire 40 and the corrugated tube 50 may be fixed by winding an adhesive tape 70 on the side opposite to the side closer to the second opening 23a than the rib 30.
[0112] Also, heretofore, the protruding dimension from the extending portion 27 of the rib 30 has been described as being equal to or less than the height from the small-diameter cylindrical portion 51 to the large-diameter cylindrical portion 52 in the corrugated tube 50, but this is not an essential configuration. For example, the protruding dimension from the extending portion 27 of the rib 30 may be larger than the height from the small-diameter cylindrical portion 51 to the large-diameter cylindrical portion 52 in the corrugated tube 50.
[0113] Also, heretofore, the dimension of the rib 30 in the extending direction of the electric wire 40 has been described as being equal to or less than the dimension of the small-diameter cylindrical portion 51, but this is not an essential configuration. For example, the dimension of the rib 30 in the extending direction of the electric wire 40 may include a portion larger than the dimension of the small-diameter cylindrical portion 51.
[0114] Also, in the wire harness 110, a corrugated tube 50 having the same size as the corrugated tube 50 of the first embodiment is adopted, and one end portion and the other end portion along the circumferential direction of the corrugated tube 50 are deformed so as to overlap each other, corresponding to the small electric wire 40, but this is not an essential configuration. In the wire harness 110, a corrugated tube smaller than the corrugated tube 50 of the first embodiment and having a size corresponding to the electric wire 40 may be adopted. Also in the wire harness 110, similar to the first embodiment, one end portion and the other end portion along the circumferential direction of the corrugated tube 50 may not overlap each other.
[0115] Note that the respective configurations described in the above-described embodiments and respective modification examples can be appropriately combined as long as they do not conflict with each other.
