Description

[Technical Field]

[0001] The present invention relates to a length adjuster that is attached to an elongated body that is routed in, for example, a vehicle, and a wire harness with a length adjuster. [Background technology]

[0002] In a vehicle, elongated bodies such as wire harnesses that electrically connect various electronic devices and tubes through which fluids pass may be routed three-dimensionally with curved portions. Patent Document 1 discloses a wiring structure for a wire harness as an arrangement structure for such elongated bodies.

[0003] Furthermore, with the recent increase in electronic devices in vehicles, autonomous driving, and electrification, the wiring structure of wire harnesses tends to become larger and more complex in terms of the wiring routes. In such a wiring structure for a large-sized wire harness, the length of the main wire and the branch wires branching off from the main wire increases, which may reduce workability.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-196270 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above-mentioned problems, an object of the present invention is to provide a length adjuster and a wire harness with a length adjuster that can improve the ease of wiring a long body. [Means for solving the problem]

[0006] This invention is characterized in that it is a length adjustment device having a storage section that stores a storage portion that is part of a long body, and the storage section is provided with a path regulating section that regulates the path of the storage portion in the storage section and a length adjusting section that adjusts the length of the storage portion, and the path regulating sections are provided in plurality, and the intersecting direction is a direction that intersects with a first direction that is a direction along an imaginary line connecting adjacent path regulating sections on the path, and the length adjusting section is provided with a sliding abutment section that slides in the intersecting direction between adjacent path regulating sections on the path and abuts with the storage portion, and a biasing section that biases the sliding abutment section in a direction away from the imaginary line.

[0007] The present invention is also characterized in that it is a wire harness with a length adjuster, which includes a wire harness that is an elongated body, and a length adjuster that accommodates a portion of the wire harness and adjusts the length of the accommodated portion of the wire harness, the length adjuster having an accommodating portion that accommodates the accommodated portion, the accommodating portion being equipped with a path regulating portion that regulates the path of the accommodated portion and a length adjuster that adjusts the length of the accommodated portion, the path regulating portions being provided in plurality, and the intersecting direction being a direction that intersects with a first direction that is a direction along an imaginary line connecting adjacent path regulating portions on the path, the length adjuster being equipped with a sliding abutment portion that slides in the intersecting direction between adjacent path regulating portions on the path and abuts with the accommodated portion, and a biasing portion that biases the sliding abutment portion in a direction away from the imaginary line.

[0008] The elongated body includes a wire harness, a tube, and the like. Specifically, the wire harness includes not only a bundle of insulated wires formed by bundling a plurality of insulated wires, or a single insulated wire, but also a communication cable such as an optical fiber cable or a coaxial cable for transmitting information, or a bundle of communication cables. The tube also includes a hose through which a fluid such as washer fluid or coolant flows, and a corrugated tube through which the wire harness is inserted. It also includes a bundle of a wire harness and a tube.

[0009] The accommodated portion includes not only a portion of the elongated body that is always accommodated in the accommodation portion, but also a portion of the elongated body that is accommodated in the accommodation portion or pulled out from the accommodation portion. Furthermore, accommodating a portion of the elongated body as described above includes not only surrounding the entire periphery of the elongated body but also arranging the elongated body in at least a part of the accommodating section, specifically including a state in which the elongated body is placed on or fixed to a plate-like portion of the accommodating section.

[0010] The path regulator may be configured to regulate the path of the elongated body, and the number of elongated bodies whose paths are regulated by one path regulator may be one or more. The path regulator may include an insertion portion that connects the inside and outside of the storage portion and through which the elongated body is inserted, a fixing portion that fixes the elongated body by wrapping it with tape or a cable tie, or the like, and a protrusion that, inside the storage portion, wraps the elongated body around it to regulate the path.

[0011] The length adjustment section may be configured to adjust the length of the accommodated portion, and the number of elongated bodies whose lengths are adjusted by one length adjustment section may be one or more. The biasing portion may be made of any material capable of biasing the slide contact portion, such as a spring, rubber, etc. Specifically, the spring may be a compression spring, a tension spring, a leaf spring, etc.

[0012] According to the present invention, the workability of routing the elongated body can be improved. In more detail, the path of the accommodated portion accommodated in the accommodation portion is restricted by the path restricting portion, and is curved by the contact of the slide abutment portion biased by the biasing portion, so that the length of the accommodated portion can be made longer than when it is routed linearly along an imaginary straight line. In other words, since the length of the accommodated portion accommodated in the accommodation portion is longer, the apparent length of the elongated body equipped with the length adjuster can be shortened.

[0013] The apparent length of the elongated body refers to the distance from one end to the other end of the elongated body when the accommodated portion is accommodated in the accommodating part and the length is adjusted by the length adjuster, including, for example, the distance from one end to the other end of the main line of the wire harness and the distance from the base end to the tip end of a branch line branching from the main line of the wire harness.

[0014] Furthermore, by sliding the slide contact portion in a direction approaching the imaginary line, the length of the accommodated portion curved by the slide contact portion can be made shorter than before the slide contact portion was slid, thereby making it possible to lengthen the apparent length of the elongated body equipped with the length adjuster.

[0015] In this way, by adjusting the sliding distance of the slide abutment portion and thereby adjusting the length of the accommodated portion, the elongated body can be routed while adjusting the apparent length of the elongated body. Therefore, during the routing work, interference between the elongated body and other components and between the elongated body and the worker can be prevented, thereby improving the efficiency of the routing work.

[0016] Furthermore, since the apparent length of the elongated body can be adjusted using the length adjuster, even if the length of the routing path differs depending on the vehicle model, such as a main line running along the side sill of a vehicle, the apparent length of the elongated body can be adjusted using the length adjuster, and the elongated body can be routed along the desired routing path.

[0017] As an aspect of the present invention, a slide restricting portion may be provided that restricts the sliding range of the slide abutment portion. With this invention, the slide regulating portion can prevent the slide abutment portion from sliding excessively, and an excessively slid slide abutment portion can prevent the accommodated portion from being excessively bent, thereby reducing the load on the accommodated portion.

[0018] As another aspect of the present invention, a contact restricting portion may be provided that restricts the position of the slidable contact portion in the intersecting direction. According to this invention, the abutment control portion can prevent unintended sliding of the slide abutment portion, thereby preventing unintended changes in the length of the accommodated portion and reliably reducing the load on the accommodated portion caused by the slide abutment portion biased by the biasing portion.

[0019] Note that restricting the position in the intersecting direction as described above means that sliding of the slide abutment portion in the intersecting direction can be restricted, and this may include restricting not only sliding of the slide abutment portion in a direction away from the imaginary line but also sliding of the slide abutment portion in a direction approaching the imaginary line. Specifically, the biasing force of the biasing portion may restrict the slide abutment portion from sliding in a direction away from the imaginary line, or the slide abutment portion abutting the accommodated portion may restrict sliding of the slide abutment portion in a direction approaching the imaginary line by an external force acting on the accommodated portion in a direction pulling the accommodated portion out of the accommodating portion. The contact restricting portion includes a barb that restricts sliding of the contact portion in the direction in which the biasing force of the biasing portion acts, and a portion that restricts the position by locking or fixing the sliding contact portion.

[0020] In another aspect of the present invention, a plurality of length adjustment sections are provided between the path regulating sections, the length adjustment sections are arranged in parallel at predetermined intervals in the first direction, and the slide abutment sections of adjacent length adjustment sections in the path may slide in opposite directions in the intersecting direction.

[0021] According to this invention, the accommodated portion can be wrapped around a length adjusting part arranged on one side in the transverse direction from one side in the transverse direction, and the accommodated portion can be wrapped around a length adjusting part arranged on the other side in the transverse direction from the other side in the transverse direction, thereby allowing the accommodated portion to be curved in a wavy shape and routed. This allows the length of the accommodated portion to be extended, and the range of apparent lengths of the elongated body that can be adjusted by the length adjuster to be increased.

[0022] In another aspect of the present invention, the storage section may be configured to be able to store the stored portions of a plurality of the elongated bodies, and the length adjustment section may be provided corresponding to each of the plurality of elongated bodies. According to this invention, the lengths of the accommodated portions of a plurality of elongated bodies can be adjusted with one length adjuster, thereby further improving the ease of installation work.

[0023] The aforementioned multiple elongated bodies include multiple elongated bodies with the same diameter and multiple elongated bodies with different diameters. It also includes a case where the bundled elongated bodies are branched into multiple bodies inside the accommodating section. Specifically, it includes a case where a main wire of a wire harness, which is a bundle of multiple insulated electric wires, is branched into multiple bodies inside the accommodating section. When branching, the diameters and number of wires may be approximately uniform, or the diameters and number of wires may be unevenly distributed.

[0024] In another aspect of this invention, the storage section is configured to be able to store the stored portions of the two elongated bodies, one of the two elongated bodies being a first elongated body and the other being a second elongated body, and among the multiple length adjustment sections, the length adjustment section that adjusts the length of the stored portion of the first elongated body being a first length adjustment section, and the length adjustment section that adjusts the length of the stored portion of the second elongated body being a second length adjustment section, and the first length adjustment section and the second length adjustment section are arranged adjacent to each other in the first direction, and each of the sliding abutment sections may slide to the opposite side of the intersecting direction.

[0025] With this invention, the accommodated portion of the first elongated body and the accommodated portion of the second elongated body can be arranged in an intersecting wavy pattern by wrapping the accommodated portion around the first adjusting portion and the second adjusting portion, which are adjacent in the first direction and slide on opposite sides of the intersecting direction, from the outside in the intersecting direction.

[0026] In other words, the accommodated portion of the second elongated body can be arranged in the gaps between the accommodated portions of the first elongated body which is arranged in a wavy pattern, and the accommodated portion of the first elongated body can be arranged in the gaps between the accommodated portions of the second elongated body which is arranged in a wavy pattern, so that the internal space of the storage section can be utilized efficiently.

[0027] In another aspect of the present invention, the biasing force of the first biasing portion, which is the biasing portion of the first length adjustment portion, may be set stronger than the biasing force of the second biasing portion, which is the biasing portion of the second length adjustment portion that adjusts the length of the accommodated portion of the second elongated body, which has a smaller diameter than the first elongated body.

[0028] According to this invention, the slide abutment portion biased by the first biasing portion with a strong biasing force is brought into contact with the accommodated portion of the large-diameter first elongated body, thereby reliably bending the accommodated portion of the large-diameter first elongated body, thereby reliably adjusting the length of the accommodated portion of the large-diameter first elongated body.

[0029] Furthermore, the slide abutment portion, which is biased by the second biasing portion with a weaker biasing force, can be brought into contact with the accommodated portion of the small-diameter second elongated body. This allows the slide abutment portion to be reliably slid by an external force applied to the small-diameter second elongated body when the accommodated portion of the small-diameter second elongated body is pulled out of the accommodation portion, making it possible to easily adjust the apparent length of the small-diameter second elongated body. In this way, by creating a difference in the biasing force between the first biasing portion and the second biasing portion, the length of the accommodated portion of the first elongated body and the second elongated body, which have different diameters, can be reliably adjusted, and the apparent length can be easily adjusted.

[0030] In another aspect of the invention, insertion portions through which the elongated body passes are provided on both sides of the path in the storage section, and of the insertion portions provided on both sides of the path, the insertion portion arranged on one side of the path is designated as a one-side insertion portion, and two one-side insertion portions are provided at an interval in the intersecting direction, and the path regulating portion is arranged inside the storage section between the two one-side insertion portions and between the one-side insertion portion and the length adjustment portion.

[0031] According to this invention, unintended interference between the elongated body and the slide abutment portion can be prevented on the side of one of the insertion portions, and damage to the elongated body can be prevented. In more detail, the long body that passes through one of the pair of insertion portions is wrapped around a path regulating portion arranged between the one insertion portion and the length adjustment portion from the side of the one insertion portion, and the path regulating portion can distribute the accommodated portion in the cross direction.

[0032] This makes it possible to prevent unintended interference between the accommodated portion and the slide abutment portion when extending the apparent length of the elongated body. In other words, even if the slide abutment portion arranged on one side in the transverse direction slides to the other side in the transverse direction and the slide abutment portion arranged on the other side in the transverse direction slides to one side in the transverse direction, unintended interference between the accommodated portion distributed in the transverse direction and the slide abutment portion on the side of the one-side insertion portion can be prevented, and damage to the elongated body can be prevented.

[0033] As another aspect of the present invention, a plurality of the length adjusters and the path regulators may be provided, and at least one of the length adjusters may be disposed between the path regulators. According to this invention, the path of the accommodated portion can be reliably restricted by the plurality of path restricting portions, while the length of the accommodated portion can be reliably adjusted by the plurality of length adjusting portions.

[0034] In another aspect of the present invention, the storage section may be configured to be able to store the stored portions of a plurality of the elongated bodies, and the length adjustment section may be provided corresponding to each of the plurality of elongated bodies. According to this invention, the lengths of the accommodated portions of the plurality of elongated bodies can be adjusted, and the ease of installation can be further improved.

[0035] In another aspect of the present invention, the storage section is configured to be able to store the stored portions of the two elongated bodies, and insertion sections through which the elongated bodies are inserted are provided on both sides of the path of the storage section, a direction connecting the insertion sections on both sides of the path is an insertion direction, and the insertion direction intersects with the intersecting direction, and among the path regulating sections, the path regulating section that regulates one of the elongated bodies is a first path regulating section, and the path regulating section that regulates the other of the elongated bodies is a second path regulating section, and among the length adjusting sections, the length adjusting section that adjusts the length of one of the elongated bodies is a first length adjusting section, and the length adjusting section that adjusts the length of the other of the elongated bodies is a second length adjusting section, and the first path regulating section a plurality of the second path regulating portions are provided on the other side of the transverse direction at predetermined intervals in the insertion direction, the first path regulating portions and the second path regulating portions are arranged alternately in the insertion direction, one first length adjusting portion is provided between the first path regulating portions, and one second length adjusting portion is provided between the second path regulating portions, the first length adjusting portion is arranged on one side of the second path regulating portion, and the slide abutment portion is urged to the other side in the transverse direction, and the second length adjusting portion is arranged on the other side of the first path regulating portion, and the slide abutment portion is urged to the one side in the transverse direction.

[0036] With this invention, the length of the accommodated portion of the second elongated body can be adjusted by the second length adjustment portion by utilizing the other side of the first path regulating portion that regulates the path of the first elongated body, and further, the length of the accommodated portion of the first elongated body can be adjusted by the first length adjustment portion by utilizing one side of the second path regulating portion that regulates the path of the second elongated body, so that the internal space of the storage portion can be utilized efficiently.

[0037] In another aspect of the present invention, one of the two elongated bodies may be a first elongated body and the other a second elongated body, and the biasing force of the first biasing portion, which is the biasing portion of the first length adjustment part, may be set stronger than the biasing force of the second biasing portion, which is the biasing portion of the second length adjustment part that adjusts the length of the accommodated portion of the second elongated body, which has a smaller diameter than the first elongated body.

[0038] According to this invention, the slide abutment portion biased by the first biasing portion with a strong biasing force is brought into contact with the accommodated portion of the large-diameter first elongated body, thereby reliably bending the accommodated portion of the large-diameter first elongated body, thereby reliably adjusting the length of the accommodated portion of the large-diameter first elongated body.

[0039] Furthermore, the slide abutment portion, which is biased by the second biasing portion with a weaker biasing force, can be brought into contact with the accommodated portion of the small-diameter second elongated body. This allows the slide abutment portion to be reliably slid by an external force applied to the small-diameter second elongated body when the accommodated portion of the small-diameter second elongated body is pulled out of the accommodation portion, making it possible to easily adjust the apparent length of the small-diameter second elongated body. In this way, by creating a difference in the biasing force between the first biasing portion and the second biasing portion, the length of the accommodated portion of the first elongated body and the second elongated body, which have different diameters, can be reliably adjusted, and the apparent length can be easily adjusted.

Furthermore, the upper side along the up-down direction Z is referred to as the upper side ZU, and the lower side along the up-down direction Z is referred to as the lower side ZD. This direction is the same in FIGS.

[0047] As shown in FIG. 1, a wire harness 1 with a length adjuster for electrically connecting electronic devices mounted on a vehicle is composed of a wire harness 100, which is an elongated body arranged in a longitudinal direction X, and a length adjuster 10 that accommodates an accommodated portion 101, which is a part of the wire harness 100, and adjusts the length of the accommodated portion 101 of the accommodated wire harness 100.

[0048] The wire harness 100 includes two wires, a large-diameter harness 110 and a small-diameter harness 120, each of which is provided at its end with a connector 500 for connecting to an electronic device. In this case, the apparent length, which is the distance along the longitudinal direction X from the connector 500 on the left side XL to the connector 500 on the right side XR of the wire harness 100, is referred to as apparent length L.

[0049] The length adjuster 10 has a storage section 20 that stores the stored portion 101, and the storage section 20 is provided with a path regulating section 30 that regulates the path of the stored portion 101, a length adjusting section 40 that adjusts the length of the stored portion 101, and an adjusting section regulating body 50 that regulates the length adjusting section 40.

[0050] 2, the storage unit 20 is composed of a box-shaped storage unit main body 21 that opens to the upper side ZU, and a storage lid part 22 that closes the opening of the storage unit main body 21. The storage unit main body 21 and the storage lid part 22 can be locked and fixed by placing the storage lid part 22 over the storage unit main body 21.

[0051] The storage unit main body 21 is a box-shaped body that is generally rectangular in plan view. The storage unit main body 21 is composed of a rectangular parallelepiped lower body part 211 that forms the lower part of the storage unit main body 21, a plurality of groove-like groove parts 212 provided in the lower body part 211, and a wall-like storage wall part 213 that stands upright from the outer periphery of the lower body part 211.

[0052] As shown in FIGS. 3(a) and 3(b), the main body lower part 211 is a flat rectangular parallelepiped having a long side in the longitudinal direction X and formed into a rectangular shape in a plan view. The groove portion 212 is a groove that extends in the width direction Y, and extends from the center of the main body lower portion 211 in the width direction Y to an end portion on the front side YF or the back side YB, and has an opening formed on the outside in the width direction Y (see FIG. 3(a)). Further, near the opening on the outside in the width direction Y of the groove portion 212, a rectangular groove portion 214 that is rectangular in plan view and has long sides in the longitudinal direction X is formed.

[0053] As shown in FIGS. 3(b) and 3(c), the groove portion 212 is a groove recessed on the lower side ZD, and is formed in a convex shape protruding on the upper side ZU in front view. As shown in Figures 3(d) and 3(e), the groove 212 is provided with a pair of protruding pieces 218 that protrude inward in the longitudinal direction X from both ends in the longitudinal direction X and are arranged in parallel in the width direction Y. More specifically, the protruding pieces 218 are formed in the shape of a pair of triangles that protrude opposite each other inward in the longitudinal direction X. The protruding pieces 218 are formed in a barbed shape that extends in a direction away from the outer opening of the groove 212 in the width direction Y. Such protruding pieces 218 are provided continuously at predetermined intervals in the width direction Y.

[0054] As shown in FIGS. 3(a) and 3(e), the rectangular groove portion 214 is formed in a groove shape that is longer in the longitudinal direction X than the groove portion 212, and opens to the upper side ZU.

[0055] Such grooves 212 are provided at six locations at predetermined intervals in the longitudinal direction X, and are named, in order from the left side XL, as grooves 212a, 212b, 212c, 212d, 212e, and 212f. The grooves 212a, 212d, and 212e form openings on the back side YB, and the grooves 212b, 212c, and 212f form openings on the front side YF.

[0056] Next, a detailed description will be given of the arrangement of the groove portion 212. First, the groove portions 212b, 212c, and 212f that open to the front side YF will be explained. The groove portion 212c is arranged substantially in the center in the longitudinal direction X, the groove portion 212b is arranged at a predetermined distance from the groove portion 212c on the left side XL, and the groove portion 212f is arranged at a predetermined distance from the groove portion 212c on the right side XR.

[0057] Specifically, groove 212b is disposed on the right side XR of the center between groove 212c and the left end of main body lower part 211 in the longitudinal direction X. Groove 212f is formed on the right side XR of the center between groove 212c and the right end of main body lower part 211. In other words, the distance between groove 212b and groove 212c is shorter than the distance between groove 212b and groove 212f, and more specifically, is approximately half the distance.

[0058] Next, the grooves 212a, 212d, and 212e that open to the rear side YB will be described. In the longitudinal direction X, the groove 212a is provided at a position spaced a predetermined distance from the groove 212b toward the left side XL. The groove 212d is provided at a position spaced a predetermined distance from the groove 212c toward the right side XR. The groove 212e is provided at a position spaced a predetermined distance from the groove 212f toward the left side XL.

[0059] The intervals in the longitudinal direction X between groove portion 212a and groove portion 212b, groove portion 212c and groove portion 212d, and groove portion 212e and groove portion 212f are approximately the same. Furthermore, the interval between groove portion 212a and groove portion 212d is approximately the same as the interval between groove portion 212c and groove portion 212f, and the interval between groove portion 212d and groove portion 212e is approximately the same as the interval between groove portion 212b and groove portion 212f.

[0060] The storage wall portion 213 is a frame-shaped wall portion that stands from the outer periphery of the main body lower portion 211 toward the upper side ZU, and the height of the storage wall portion 213 is approximately the same as the length of the main body lower portion 211 along the vertical direction Z. The housing wall 213 has a plurality of cutouts formed at both ends in the longitudinal direction X and both ends in the width direction Y (see FIG. 3(a)). More specifically, cutouts into which the wire harness 100 can be inserted are formed at both ends in the longitudinal direction X of the housing wall 213, and the cutout on the left side XL is a left-side insertion portion 215, and the cutout on the right side XR is a right-side insertion portion 216.

[0061] The left-side insertion portion 215 is formed at two locations spaced apart from the center of the accommodating body 21 in the width direction Y by an equal distance in the width direction Y. The right-side insertion portion 216 is formed at one location in the center of the width direction Y. At both ends in the width direction Y of the storage wall 213, width side notches 217 having a predetermined width in the longitudinal direction X are formed above the outer opening ZU of the groove 212 in the width direction Y.

[0062] 2, the storage lid 22 is composed of a top plate 221 that is rectangular in plan view and has long sides along the longitudinal direction X, and a lid side wall 222 that extends downward ZD from the outer periphery of the top plate 221. The lid side wall 222 is formed to fit around the storage wall 213.

[0063] The top plate portion 221 has a through-hole portion 223 that penetrates in the vertical direction Z, at a position corresponding to the upper side ZU of the groove portion 212 when the storage body 21 and the storage lid portion 22 are assembled (see Figure 5). The through-hole portion 223 is a rectangular through-hole in plan view with its long sides in the width direction Y, and extends from approximately the center of the top plate portion 221 in the width direction Y to near the end of the corresponding groove portion 212 on the opening side in the width direction Y.

[0064] The path regulation section 30 includes a plate-shaped regulation section 31 extending outward in the longitudinal direction X of the storage section main body 21, and a cylindrical regulation section 32 having a substantially cylindrical shape provided inside the storage section main body 21 (see FIG. 3(a)). The plate-shaped restricting portion 31 is a plate-shaped member extending outward in the longitudinal direction X from the lower ends of the left-side insertion portion 215 and the right-side insertion portion 216, and is formed so that the outer side in the longitudinal direction X is wider in the width direction Y (see FIG. 3(a)). Such a plate-shaped restricting portion 31 is configured to be flush with the upper surface of the main body lower portion 211.

[0065] The cylindrical restricting portion 32 is a generally cylindrical body that stands from the main body lower portion 211 toward the upper side ZU, and has a barb at its upper end that widens like an umbrella (see FIG. 2). The length of the cylindrical restricting portion 32 in the up-down direction Z from the lower end of the barb to the lower end of the barb is slightly longer than the sum of the diameters of the large-diameter harness 110 and the small-diameter harness 120. The cylindrical restricting portion 32 is provided in the center of the main body lower portion 211 in the width direction Y and approximately in the center between the left end of the main body lower portion 211 and the groove portion 212a in the longitudinal direction X. The dashed line connecting the cylindrical restricting portion 32 and the right-side insertion portion 216 is defined as an imaginary straight line X1 (see FIG. 3(a)).

[0066] The length adjusting section 40 includes a large diameter adjusting section 41 that adjusts the length of the large diameter accommodated section 111, and a small diameter adjusting section 42 that adjusts the length of the small diameter accommodated section 121 (see FIG. 2). The large diameter adjustment part 41 is composed of a large diameter sliding part 411 that slides in the groove part 212, and a large diameter spring part 412 that is a spring member that urges the large diameter sliding part 411 outward in the width direction Y. In the following, the large diameter sliding part 411 attached to the groove part 212a will be described.

[0067] As shown in Figures 4(a) and 4(b), the large-diameter sliding portion 411 is integrally composed of a large-diameter sliding body 413 that is elongated in the longitudinal direction X in a plan view and has a semi-cylindrical shape, a large-diameter sliding protrusion 414 that protrudes from the large-diameter sliding body 413 to the upper side ZU, and a large-diameter sliding convex portion 415 that is convex in a front view and is provided on the lower side ZD of the large-diameter sliding body 413.

[0068] The large-diameter sliding body 413 is a plate-like member in plan view, with both ends in the longitudinal direction X and on the far side YB chamfered into an arc shape. The large-diameter sliding body 413 is formed so that the width-side cutout portion 217 can be inserted therethrough. The large-diameter sliding protrusion 414 is a rectangular parallelepiped that protrudes upward from the front side YF and the center in the longitudinal direction X of the large-diameter sliding body 413 .

[0069] The large-diameter sliding protrusion 415 is formed in a convex shape in a front view that is slightly smaller than the cross-sectional shape of the groove 212, and is slidable in the width direction Y relative to the groove 212. Specifically, the length of the lower part of the large-diameter sliding protrusion 415 in the longitudinal direction X is shorter than the length of the groove 212 in the longitudinal direction X, and is longer than the inner width of the pair of protruding pieces 218. The large diameter spring portion 412 is a compression spring that can be inserted into the groove portion 212, and has a stronger biasing force than the small diameter spring portion 422 described below. The length of the large diameter spring portion 412 is approximately the same as the length of the groove portion 212 along the width direction Y.

[0070] The small diameter adjusting part 42 has substantially the same configuration as the large diameter adjusting part 41, and is integrally formed with a small diameter sliding part 421 that slides in the groove part 212 and a small diameter spring part 422 that is a spring member that urges the small diameter sliding part 421 outward in the width direction Y. Note that the following description will be based on the small diameter sliding part 421 attached to the groove part 212d.

[0071] As shown in Figures 4(c) and 4(d), the small diameter sliding portion 421 is composed of a small diameter sliding body 423 that is shorter in length along the longitudinal direction X than the large diameter sliding body 413, a small diameter sliding protrusion 424 that has the same configuration as the large diameter sliding protrusion 414, and a small diameter sliding protrusion 425 that has the same configuration as the large diameter sliding protrusion 415. The small diameter spring portion 422 has the same configuration as the large diameter spring portion 412, except that the biasing force of the small diameter spring portion 422 is weaker than that of the large diameter spring portion 412.

[0072] As shown in Figure 2, the adjustment portion regulating body 50 is composed of a groove mounting portion 51 that is convex in front view and can be fixed by being pressed into the rectangular groove portion 214 through an opening on the upper side ZU, and an approximately disk-shaped adjustment disk portion 52 that is provided on the upper side ZU of the groove mounting portion 51.

[0073] The groove mounting portion 51 is a rectangular parallelepiped in plan view that has approximately the same shape as the rectangular groove portion 214, and the length of the groove mounting portion 51 in the vertical direction Z is approximately the same as the length of the groove portion 212 and the rectangular groove portion 214 in the vertical direction Z. The adjustment disk portion 52 is formed in a flat, approximately disk-like shape, and is configured so that its lower end surface comes into contact with the upper end surface of the main body lower portion 211 when the adjustment portion restricting body 50 is attached to the rectangular groove portion 214.

[0074] The length adjuster 10 is made up of the storage section 20, path regulation section 30, length adjustment section 40, and adjustment section regulation body 50 configured as described above. Specifically, the length adjustment section 40 and the adjustment section regulation body 50 are attached to the groove section 212 provided in the storage section main body 21 of the storage section 20 (see FIG. 5(a)).

[0075] More specifically, the large diameter spring portion 412 is inserted into the groove portions 212a, 212c, and 212e, and then the large diameter sliding convex portion 415 is inserted so that the chamfered side of the large diameter sliding main body 413 faces outward in the width direction Y. Thereafter, the groove mounting portion 51 is press-fitted into the rectangular groove portion 214 from the upper side ZU to fix the adjuster restricting body 50. The large diameter adjuster 41 attached to the groove portion 212a is referred to as the large diameter adjuster 41a, the large diameter adjuster 41 attached to the groove portion 212c is referred to as the large diameter adjuster 41c, and the large diameter adjuster 41 attached to the groove portion 212e is referred to as the large diameter adjuster 41e.

[0076] Furthermore, after inserting the small diameter spring portion 422 into the groove portions 212b, 212d, and 212f, the small diameter sliding convex portion 425 is inserted so that the chamfered side of the small diameter sliding main body 423 faces outward in the width direction Y. Thereafter, the groove mounting portion 51 is press-fitted into the rectangular groove portion 214 from the upper side ZU to fix the adjuster restriction body 50. The small diameter adjuster 42 attached to the groove portion 212b is referred to as the small diameter adjuster 42b, the small diameter adjuster 42 attached to the groove portion 212d as the small diameter adjuster 42d, and the small diameter adjuster 42 attached to the groove portion 212f as the small diameter adjuster 42f.

[0077] In this way, the length adjuster 40 attached to the storage body 21 is provided between the plate-shaped restricting portion 31 on the right side XR and the cylindrical restricting portion 32 in the longitudinal direction X (see FIG. 2). In addition, the length adjuster 40 is prevented from falling off from the storage body 21 by the adjuster restricting body 50.

[0078] Next, the storage lid 22 is attached to the storage body 21 to which the length adjuster 40 and the adjuster restrictor 50 are attached. At this time, as shown in FIG. 5(b), the large-diameter sliding protrusion 414 of the large-diameter adjuster 41 and the small-diameter sliding protrusion 424 of the small-diameter adjuster 42 are inserted into the through-hole 223 provided in the storage lid 22. Then, with the storage lid 22 attached to the storage body 21, the upper end portions of the large-diameter sliding protrusion 414 and the small-diameter sliding protrusion 424 are slightly exposed on the upper side ZU above the upper end surface of the storage lid 22.

[0079] Next, a method of attaching the length adjuster 10 to the wire harness 100 and a method of adjusting the apparent length L of the wire harness 100 will be described with reference to FIG. The wire harness 100 is routed through the length adjuster 10 from which the housing lid portion 22 has been removed. Specifically, as shown in FIG. 6( a), the large-diameter harness 110 is inserted through the left-side insertion portion 215 on the near side YF and wound around the cylindrical restricting portion 32 from the left side XL. Then, the large-diameter harness 110 is wound around the large-diameter adjusting portion 41a from the far side YB, wound around the large-diameter adjusting portion 41c from the near side YF, and wound around the large-diameter adjusting portion 41e from the far side YB. The large-diameter harness 110 thus wound around the large-diameter adjusting portion 41 is then inserted through the right-side insertion portion 216. In this manner, the large-diameter accommodated portion 111 of the large-diameter harness 110 is routed in a wavy manner.

[0080] The thin harness 120 is inserted through the left-side insertion portion 215 on the rear side YB and wound around the cylindrical restricting portion 32 from the left side XL. Then, it is wound around the thin diameter adjusting portion 42b from the front side YF, wound around the thin diameter adjusting portion 42d from the rear side YB, and wound around the thin diameter adjusting portion 42f from the front side YF. The thin harness 120 wound around the thin diameter adjusting portion 42 in this manner is inserted through the right-side insertion portion 216. The thin diameter accommodated portion 121 of the thin harness 120 thus arranged is arranged in a wavy pattern that intersects with the thick diameter harness 110. At the intersection of the thick diameter harness 110 and the thin diameter harness 120, the thin diameter harness 120 is disposed on the upper side ZU.

[0081] In this way, by assembling the housing lid portion 22 to the housing main body 21 in which the wire harness 100 is routed, the length adjuster 10 can be attached to the wire harness 100 to configure the wire harness with length adjuster 1. In the wire harness with length adjuster 1 configured in this way, the routing path of the large diameter harness 110 is route R1, and the routing path of the small diameter harness 120 is route R2. As shown in FIG. 6(a), the apparent length L of the wire harness 100 in a state where the accommodated portion 101 of the wire harness 100 is entirely accommodated in the accommodating portion 20 is defined as the shortest length L1.

[0082] Next, a method for adjusting the apparent length L of the wire harness 100 in the wire harness 1 with a length adjuster will be described. An external force F1 toward the right side XR is applied to the wire harness 100 inserted through the right-side insertion portion 216, i.e., the large diameter harness 110 and the small diameter harness 120. As a result, as shown in FIG. 6(a), an external force F2 toward the inside in the width direction Y acts on the large diameter adjustment portion 41 around which the large diameter harness 110 is wound and the small diameter adjustment portion 42 around which the small diameter harness 120 is wound. Specifically, the external force F2 in a direction approaching the imaginary straight line X1 acts on the large diameter adjustment portion 41 and the small diameter adjustment portion 42.

[0083] As a result, as shown in Figure 6(b), the large-diameter accommodated portion 111 and the small-diameter accommodated portion 121 are pulled out from the accommodating portion 20, shortening the lengths of the large-diameter accommodated portion 111 and the small-diameter accommodated portion 121, and making the apparent length L of the wire harness 100 longer than the shortest length L1.

[0084] 6(c), by pulling out the entire accommodated portion 101 of the wire harness 100 from the accommodation portion 20, the large diameter sliding convex portion 415 of the large diameter adjustment portion 41 and the small diameter sliding convex portion 425 of the small diameter adjustment portion 42 are engaged with the protruding piece 218 provided in the groove portion 212. This prevents the large diameter adjustment portion 41 and the small diameter adjustment portion 42 from unintentionally sliding outward in the width direction Y due to the biasing forces of the large diameter spring portion 412 and the small diameter spring portion 422. In other words, unintentional extension of the lengths of the large diameter accommodated portion 111 and the small diameter accommodated portion 121 can be prevented, and unintentional shortening of the apparent length L of the large diameter harness 110 and the small diameter harness 120 can be prevented.

[0085] Furthermore, when the entire accommodated portion 101 is pulled out from the accommodation portion 20, the large diameter sliding protrusion 414 of the large diameter adjustment portion 41 and the small diameter sliding protrusion 424 of the small diameter adjustment portion 42 abut against the inner surface in the width direction Y of the through-hole portion 223. This prevents the large diameter adjustment portion 41 and the small diameter adjustment portion 42 from sliding excessively, and prevents unintended interference between the large diameter adjustment portion 41 and the small diameter adjustment portion 42 and the accommodated portion 101 (see FIG. 6(c)). The apparent length L of the wire harness 100 in a state where the housed portion 101 of the wire harness 100 is completely pulled out is defined as the maximum length L2.

[0086] Furthermore, by applying an external force to the thick-diameter sliding protrusion 414 and the thin-diameter sliding protrusion 424 in the direction away from the imaginary straight line X1 in the width direction Y, the thick-diameter adjustment part 41 and the thin-diameter adjustment part 42 can be moved in the direction away from the imaginary straight line X1.

[0087] This allows the lengths of the large-diameter accommodated portion 111 and the small-diameter accommodated portion 121 to be increased, thereby shortening the apparent length L of the large-diameter harness 110 and the small-diameter harness 120. In this way, the apparent length L of the large-diameter harness 110 and the small-diameter harness 120 can be adjusted within the range between the shortest length L1 and the longest length L2.

[0088] In this way, by arranging the large diameter harness 110 and the small diameter harness 120 in a wave-like manner that intersects with each other, the apparent length L of the large diameter harness 110 and the small diameter harness 120 can be adjusted by utilizing the gap in the route R1 of the large diameter harness 110 and the route R2 of the small diameter harness 120, and the internal space of the storage section 20 can be effectively utilized.

[0089] As described above, by adjusting the apparent length L of the wire harness 100, it is possible to prevent interference between the worker performing the wiring work and the long wire harness 100, and unintended interference between the wire harness 100 and another member, thereby improving the efficiency of the wiring work. After the wiring work of the wire harness 100 is completed, the wire harness 100 may be fixed to the plate-shaped restricting portion 31 with tape or a cable tie. Moreover, after the wiring work of the wire harness 100 is completed, the length adjuster 10 may be removed.

[0090] The large diameter sliding portion 411 that bends the large diameter accommodated portion 111 is long in the longitudinal direction X, and the small diameter sliding portion 421 that bends the small diameter accommodated portion 121 is short in the longitudinal direction X. This prevents the large diameter accommodated portion 111 from being excessively bent by the large diameter sliding portion 411 biased by the large diameter spring 412 portion with a strong biasing force, while the small diameter accommodated portion 121 is reliably bent by the small diameter sliding portion 421 biased by the small diameter spring portion 422 portion with a weak biasing force. In other words, the curvature of the curved portions of the large diameter accommodated portion 111 and the small diameter accommodated portion 121 is adjusted appropriately.

[0091] Furthermore, since the large diameter sliding protrusion 414 of the large diameter adjustment part 41 and the small diameter sliding protrusion 424 of the small diameter adjustment part 42 are inserted into the through-hole 223 of the housing lid part 22, the sliding range between the large diameter adjustment part 41 and the small diameter adjustment part 42 is restricted to outside the center part in the width direction Y of the housing main body 21. This prevents unintended interference between the large diameter adjustment part 41 and the small diameter harness 120 and between the small diameter adjustment part 42 and the large diameter harness 110.

[0092] In addition, in this embodiment, the length adjuster 10 is configured so that the thick-diameter accommodated portion 111 and the thin-diameter accommodated portion 121 are arranged in a wave-like pattern that intersects, but other configurations are also acceptable as long as the lengths of the thick-diameter accommodated portion 111 and the thin-diameter accommodated portion 121 can be adjusted.

[0093] Second Embodiment The length adjuster 10x and the wire harness with a length adjuster 1x according to the second embodiment will be described in detail below with reference to Fig. 7. In the following description, the same components as those described above will be denoted by the same reference numerals, and the description thereof will be omitted.

[0094] Here, Fig. 7 is an explanatory diagram of the wire harness 1x with a length adjuster. More specifically, Fig. 7(a) shows a plan view of the wire harness 1x with a length adjuster in a state where the housing lid portion 22x is removed, and Fig. 7(b) shows a plan view of the wire harness 1x with a length adjuster. Note that the dashed lines in Fig. 7(b) indicate the large-diameter housed portion 111 and the small-diameter housed portion 121.

[0095] The wire harness 1x with a length adjuster is composed of a wire harness 100 and a length adjuster 10x for adjusting the length of a housed portion 101. The length adjuster 10x has a housing portion 20x that houses the housed portion 101, and the housing portion 20x is provided with a path regulator 30x, a length adjuster 40, and an adjuster regulator 50x.

[0096] The storage section 20x is composed of a storage section main body 21x that opens to the upper side ZU, and a storage lid section 22x that closes the opening of the storage section main body 21x. The housing body 21x has the same configuration as the housing body 21, except for the groove 212, the rectangular groove 214, and the width-side notch 217.

[0097] A plurality of groove-shaped groove portions 212x are provided in the main body lower portion 211. The groove portions 212x are grooves that extend in the width direction Y, extending from an end portion on one side in the width direction Y to the vicinity of the other side. Further, rectangular groove portions 214x having substantially the same configuration as the rectangular groove portions 214 are provided on one outer side of the groove portions 212x in the width direction Y. The grooves 212x have the same configuration as the grooves 212 except for their length in the width direction Y and their arrangement.

[0098] The rectangular groove portion 214x is provided at a position spaced a predetermined distance inward in the width direction Y from one end of the groove portion 212x in the width direction Y. Specifically, the rectangular groove portion 214 is provided so that the distance in the width direction Y between the accommodating wall portion 213 and the rectangular groove portion 214x is sufficiently longer than the diameter of the large-diameter harness 110. The rectangular groove portion 214x has the same configuration as the rectangular groove portion 214 except for its arrangement.

[0099] Such groove portions 212x are provided at four locations spaced a predetermined distance apart in the longitudinal direction X, and the first and third groove portions 212x from the left end form openings on the front side YF, while the second and fourth groove portions 212x form openings on the back side YB. The width-side cutouts 217x have the same configuration as the width-side cutouts 217, except that they are formed at positions corresponding to the outer openings in the width direction Y of the grooves 212x.

[0100] The housing lid portion 22x has the same configuration as the housing lid portion 22 except for the through-hole portion 223. The top plate 221 of the storage lid 22x has through-holes 223x that penetrate in the plate thickness direction, at four locations that correspond to the grooves 212 when the storage lid 22x is attached to the storage body 21x. The through-holes 223x are formed from the vicinity of the end of the top plate 221 on the front side YF to the vicinity of the end of the back side YB (see FIG. 7(b)).

[0101] The path restricting portion 30x is composed of a plate-shaped restricting portion 31, a large diameter restricting portion 33 that restricts the large diameter harness 110, and a small diameter restricting portion 34 that restricts the small diameter harness 120. The large diameter restricting portion 33 and the small diameter restricting portion 34 are composed of an adjuster restricting body 50x that is substantially the same as the adjuster restricting body 50.

[0102] More specifically, the adjuster restricting body 50x is composed of a groove mounting portion 51 that is press-fitted into the rectangular groove portion 214x from the upper side ZU, and an adjuster cylindrical portion 53 that extends toward the upper side ZU from the groove mounting portion 51. The adjuster cylindrical portion 53 is a cylindrical body whose length in the vertical direction Z is slightly longer than the diameter of the large-diameter harness 110.

[0103] The storage portion 20x, the path regulator 30x, the length adjuster 40, and the adjuster regulator 50x configured in this manner constitute a length adjuster 10x. 7(a), in the storage unit main body 21x, the small diameter adjuster 42 is assembled into the groove 212x that opens to the front side YF, and then the small diameter restricting portion 34, which is the adjuster restricting body 50x, is attached. Furthermore, the large diameter adjuster 41 is assembled into the groove 212x that opens to the back side YB, and then the large diameter restricting portion 33, which is the adjuster restricting body 50x, is attached to the rectangular groove 214x. In this way, the length adjuster 10x is constructed by attaching the storage lid portion 22x to the storage unit main body 21x to which the length adjuster 40 and the adjuster restricting body 50x are assembled.

[0104] By attaching the length adjuster 10x configured in this manner to the wire harness 100, a wire harness with a length adjuster 1x is configured. To put it simply, the large diameter accommodated portion 111 of the large diameter harness 110, which passes through the left side insertion portion 215 on the front side YF, is wound around the large diameter regulating portion 33 from the front side YF, and is also wound around the large diameter adjusting portion 41 from the rear side YB.

[0105] In addition, the thin-diameter accommodated portion 121 of the thin-diameter harness 120 that passes through the left-side insertion portion 215 on the far side YB is wound around the thin-diameter regulating portion 34 from the far side YB, and is wound around the thin-diameter adjusting portion 42 from the front side YF. In this manner, the large diameter harness 110 and the small diameter harness 120 are arranged in a wavy shape and are arranged along each other.

[0106] By configuring the wire harness 1x with a length adjuster in this manner, the length of the thin-diameter accommodated portion 121 of the thin-diameter harness 120 is adjusted by utilizing the rear side YB of the thin-diameter restricting portion 33. Also, the length of the thin-diameter accommodated portion 111 of the thin-diameter harness 110 is adjusted by utilizing the front side YF of the thin-diameter restricting portion 34. This allows the internal space of the accommodation portion 20x to be used effectively.

[0107] In this embodiment, the adjuster-restricting body 50x is used to restrict the path of the accommodated portion 101, but a cylindrical restricting portion 32 may be provided instead of the adjuster-restricting body 50x. Also, the adjuster-restricting body 50x may be configured to be able to attach the cylindrical restricting portion 32.

[0108] The wire harness 1, 1x with a length adjuster configured as described above includes the wire harness 100 and the length adjuster 10 that accommodates a part of the wire harness 100 and adjusts the length of the accommodated portion 101 of the accommodated wire harness 100. The length adjuster 10, 10x has an accommodating portion 20, 20x that accommodates the accommodated portion 101. The accommodating portion 20, 20x includes a path restricting portion 30, 30x that restricts the paths R1, R2 of the accommodated portion 101 and a length adjusting portion 40 that adjusts the length of the accommodated portion 101. The path restricting portion 30, 30x is , and a width direction Y is a direction intersecting a longitudinal direction X, which is a direction along an imaginary straight line X1 connecting adjacent path regulation units 30, 30x on paths R1, R2, and the length adjustment unit 40 is provided between adjacent path regulation units 30, 30x on paths R1, R2, and is configured to slide in the width direction Y and abut against the accommodated portion 101, and is provided with a large-diameter spring portion 412 and a small-diameter spring portion 422 that urges the length adjustment unit 40 in a direction away from the imaginary straight line X1, thereby improving the ease of wiring the wire harness 100.

[0109] In detail, the accommodated portion 101 accommodated in the accommodating portion 20, 20x has the paths R1, R2 restricted by the path restricting portions 30, 30x, and is curved by the abutment of the length adjusting portion 40 biased by the large-diameter spring portion 412 or the small-diameter spring portion 422, so that the length of the accommodated portion 101 can be made longer than when it is routed linearly along the imaginary straight line X1. In other words, since the length of the accommodated portion 101 accommodated in the accommodating portion 20, 20x is increased, the apparent length L of the wire harness 100 including the length adjuster 10, 10x can be shortened.

[0110] Furthermore, by sliding the length adjustment unit 40 in a direction approaching the imaginary straight line X1, the length of the accommodated portion 101 curved by the length adjustment unit 40 can be made shorter than before sliding the length adjustment unit 40. This makes it possible to increase the apparent length L of the wire harness 100 equipped with the length adjuster 10, 10x.

[0111] In this way, by adjusting the sliding amount of the length adjustment portion 40 and adjusting the length of the accommodated portion 101, the wire harness 100 can be routed while adjusting the apparent length L of the wire harness 100. This makes it possible to prevent interference between the wire harness 100 and other components and between the wire harness 100 and the worker during the routing work, thereby improving the ease of the routing work.

[0112] Furthermore, since the apparent length L of the wire harness 100 can be adjusted by the length adjusters 10, 10x, even if the length of the wiring route varies depending on the vehicle model, such as the wire harness 100 that is routed along the side sill of the vehicle, the apparent length L of the wire harness 100 can be adjusted by the length adjusters 10, 10x, and the wire harness 100 can be routed along the desired wiring route.

[0113] In addition, since adjustment section regulating bodies 50, 50x and through-hole portions 223, 223x are provided to regulate the sliding range of the length adjustment section 40, the adjustment section regulating bodies 50, 50x and through-hole portions 223, 223x can prevent the length adjustment section 40 from sliding excessively, and the thick-diameter adjustment section 41 and the thin-diameter adjustment section 42 that have slid excessively can prevent the accommodated section 101 from being excessively bent, thereby reducing the load on the accommodated section 101.

[0114] Furthermore, since a protruding piece 218 is provided to regulate the position of the slid length adjustment part 40 in the width direction Y, the protruding piece 218 can prevent the length adjustment part 40 from sliding unintentionally, preventing the length of the accommodated part 101 from changing unintentionally, and reliably reducing the load on the accommodated part 101 caused by the large diameter sliding part 411 and the small diameter sliding part 421, which are biased by the large diameter spring part 412 and the small diameter spring part 422.

[0115] In addition, a length adjustment section 40 is provided between the cylindrical regulating section 32 and the plate-shaped regulating section 31 on the right side XR, and three thick diameter adjustment sections 41 and three thin diameter adjustment sections 42 are provided, and the thick diameter adjustment sections 41 and the thin diameter adjustment sections 42 are arranged in parallel at a predetermined interval in the longitudinal direction X, and each of the thick diameter adjustment sections 41 and the thin diameter adjustment sections 42 adjacent to each other on the paths R1 and R2 is slid to opposite sides in the width direction Y.

[0116] Therefore, by winding the accommodated portion 101 from one side in the width direction Y around the length adjustment portion 40 arranged on one side in the width direction Y, and by winding the accommodated portion 101 from the other side in the width direction Y around the length adjustment portion 40 arranged on the other side in the width direction Y, the accommodated portion 101 can be curved in a wavy shape and routed. This allows the length of the accommodated portion 101 to be extended, and the range of the apparent length L of the wire harness 100 that can be adjusted by the length adjuster 10, 10x can be increased.

[0117] Furthermore, the accommodating section 20 is configured to be able to accommodate the accommodated portions 101 of the two wire harnesses 100, and is provided with length adjustment sections 40 corresponding to each of the two wire harnesses 100, so that the lengths of the accommodated portions 101 of the two wire harnesses 100 can be adjusted with one length adjustment device 10, 10x, further improving the ease of wiring work.

[0118] Furthermore, the accommodating sections 20, 20x are configured to be able to accommodate the accommodated portions 101 of the two wire harnesses 100, one of which is a large-diameter harness 110 and the other a small-diameter harness 120, and among the multiple length adjustment sections 40, the length adjustment section 40 that adjusts the length of the large-diameter accommodated portion 111 is called the large-diameter adjustment section 41, and the length adjustment section 40 that adjusts the length of the small-diameter accommodated portion 121 is called the small-diameter adjustment section 42, and the large-diameter adjustment section 41 and the small-diameter adjustment section 42 are arranged adjacent to each other in the longitudinal direction X, and each of the large-diameter adjustment section 41 and the small-diameter adjustment section 42 is slid to the opposite side in the width direction Y.

[0119] Therefore, by wrapping the accommodated portion 101 around the thick-diameter adjustment portion 41 and the thin-diameter adjustment portion 42, which are adjacent to each other in the longitudinal direction X and slide to opposite sides in the width direction Y, from the outside in the width direction Y, the thick-diameter accommodated portion 111 and the thin-diameter accommodated portion 121 can be arranged in an intersecting wavy pattern.

[0120] In other words, the thin-diameter accommodated portion 121 can be arranged in the gaps between the thick-diameter accommodated portions 111 arranged in a wavy pattern, and the thick-diameter accommodated portion 111 can be arranged in the gaps between the thin-diameter accommodated portions 121 arranged in a wavy pattern, so the internal space of the accommodation section 20 can be utilized efficiently.

[0121] Furthermore, the biasing force of the large diameter spring portion 412 of the large diameter adjustment portion 41 is set stronger than the biasing force of the small diameter spring portion 422 of the small diameter adjustment portion 42, which adjusts the length of the small diameter accommodated portion 121, which has a smaller diameter than the large diameter harness 110. Therefore, by abutting the large diameter adjustment portion 41, which is biased by the large diameter spring portion 412 with a strong biasing force, against the large diameter accommodated portion 111, the large diameter accommodated portion 111 can be reliably curved. This allows the length of the large diameter accommodated portion 111 to be reliably adjusted.

[0122] Furthermore, the small diameter adjustment part 42, which is biased by the small diameter spring part 422 with a weak biasing force, can be brought into contact with the small diameter accommodated part 121. As a result, when the small diameter accommodated part 121 is pulled out to the outside of the accommodation part 20, the large diameter adjustment part 41 and the small diameter adjustment part 42 can be reliably slid by the external force acting on the small diameter harness 120, and the apparent length L of the small diameter harness 120 can be easily adjusted. In this way, by creating a difference in the biasing force between the large diameter spring portion 412 and the small diameter spring portion 422, the lengths of the accommodated portions 101 of the large diameter harness 110 and the small diameter harness 120, which have different diameters, can be reliably adjusted, and the apparent length L can be easily adjusted.

[0123] Furthermore, a left-side insertion portion 215 and a right-side insertion portion 216 through which the wire harness 100 is inserted are provided on both sides of the paths R1, R2 in the accommodating portion 20, and of the left-side insertion portion 215 and right-side insertion portion 216 provided on both sides in the longitudinal direction X, the left-side insertion portion 215 is arranged on the left side XL, and two left-side insertion portions 215 are provided at an interval in the width direction Y, and cylindrical regulating portions 32 are arranged inside the accommodating portion 20 between the left-side insertion portions 215 and between the left-side insertion portion 215 and the large diameter adjustment portion 41a, so that unintended interference between the wire harness 100 and the large diameter adjustment portion 41 and the small diameter adjustment portion 42 can be prevented on the left side XL, and damage to the wire harness 100 can be prevented.

[0124] In more detail, by wrapping the large-diameter harness 110 and the small-diameter harness 120 that pass through the pair of left-side insertion portions 215 around the cylindrical restricting portion 32 from the left side XL, the cylindrical restricting portion 32 can distribute the large-diameter harness 110 and the small-diameter harness 120 in the width direction Y.

[0125] This makes it possible to prevent unintended interference between the accommodated portion 101 and the large diameter adjustment portion 41 and the small diameter adjustment portion 42 when extending the apparent length L of the wire harness 100. That is, even if the large diameter adjustment portion 41a arranged on the rear side YB slides to the front side YF, or even if the small diameter adjustment portion 42b arranged on the front side YF slides to the rear side YB, unintended interference between the accommodated portion 101 distributed in the width direction Y and the large diameter adjustment portion 41 and the small diameter adjustment portion 42 on the left side XL can be prevented, and damage to the wire harness 100 can be prevented.

[0126] By distributing the large diameter harness 110 and the small diameter harness 120 in the width direction Y, it is possible to prevent unintended interference between the accommodated portion 101 and the large diameter adjustment portion 41 and the small diameter adjustment portion 42 when extending the apparent length L of the wire harness 100. That is, even if the large diameter adjustment portion 41 arranged on the rear side YB slides to the front side YF on the left side XL and the small diameter adjustment portion 42 arranged on the front side YF slides to the rear side YB on the left side XL, it is possible to prevent unintended interference between the accommodated portion 101 of the wire harness 100 distributed in the width direction Y and the large diameter adjustment portion 41 and the small diameter adjustment portion 42 on the left side XL, and it is possible to prevent damage to the wire harness 100.

[0127] In addition, multiple length adjustment units 40 and path regulation units 30x are provided, and one length adjustment unit 40 is arranged between the path regulation units 30x, so that the path regulation units 30x reliably regulate the paths R1, R2 of the accommodated portion 101, while the length adjustment unit 40 reliably adjusts the length of the accommodated portion 101.

[0128] Furthermore, the accommodating section 20x is configured to be able to accommodate the accommodated portions 101 of the two wire harnesses 100, and a length adjusting section 40 is provided corresponding to each of the two wire harnesses 100, so that the lengths of the accommodated portions 101 of the two wire harnesses 100 can be adjusted, further improving the ease of wiring work.

[0129] The accommodating portion 20x is configured to be able to accommodate the accommodated portions 101 of the two wire harnesses 100, and a left-side insertion portion 215 and a right-side insertion portion 216 through which the wire harness 100 is inserted are provided on both sides of the accommodating portion 20x in the longitudinal direction X. The direction connecting the left-side insertion portion 215 and the right-side insertion portion 216 on both sides of the paths R1 and R2 is the longitudinal direction X, and the longitudinal direction X intersects with the width direction Y. The path restricting portion 30x restricts the large-diameter harness 110. The restricting portion 30x is a large diameter restricting portion 33, and the path restricting portion 30x that restricts the small diameter harness 120 is a small diameter restricting portion 34. Of the length adjusting portions 40, the length adjusting portion 40 that adjusts the length of the large diameter harness 110 is a large diameter adjusting portion 41, and the length adjusting portion 40 that adjusts the length of the small diameter harness 120 is a small diameter adjusting portion 42. Two large diameter restricting portions 33 are provided on the front side YF at a predetermined interval in the longitudinal direction X, and the small diameter restricting portion 34 is provided on the back side YB. Two of the large diameter restricting portions 33 and the small diameter restricting portions 34 are provided at a predetermined interval in the longitudinal direction X, and the large diameter restricting portions 33 and the small diameter restricting portions 34 are alternately arranged in the longitudinal direction X. One large diameter adjusting portion 41 is provided between the large diameter restricting portions 33, and one small diameter adjusting portion 42 is provided between the small diameter restricting portions 34. The large diameter adjusting portion 41 is arranged on the front side YF of the small diameter restricting portions 34, and the large diameter adjusting portion 41 is biased toward the back side YB, and the small diameter adjusting portion 42 is arranged on the back side YB of the large diameter restricting portions 33. In addition, since the thin diameter adjustment portion 42 is biased toward the front side YF, the length of the thin diameter accommodated portion 121 can be adjusted by the thin diameter adjustment portion 42 by utilizing the rear side YB of the thin diameter restriction portion 33 that restricts the path R1 of the thin diameter harness 110, and further, the length of the thick diameter accommodated portion 111 can be adjusted by the thick diameter adjustment portion 41 by utilizing the front side YF of the thin diameter restriction portion 34 that restricts the path R2 of the thin diameter harness 120, so the internal space of the accommodation portion 20x can be used efficiently.

[0130] Furthermore, one of the two wire harnesses 100 is a large-diameter harness 110 and the other is a small-diameter harness 120, and the biasing force of the large-diameter spring portion 412 of the large-diameter adjustment portion 41 is set stronger than the biasing force of the small-diameter spring portion 422 of the small-diameter adjustment portion 42, which adjusts the length of the small-diameter accommodated portion 121, which has a smaller diameter than the large-diameter harness 110. Therefore, by bringing the large-diameter adjustment portion 41 biased by the large-diameter spring portion 412 with a strong biasing force into contact with the large-diameter accommodated portion 111, the large-diameter accommodated portion 111 can be reliably curved. This allows the length of the large-diameter accommodated portion 111 to be reliably adjusted.

[0131] Furthermore, the small diameter adjustment part 42, which is biased by the small diameter spring part 422 with a weak biasing force, can be brought into contact with the small diameter accommodated part 121. As a result, when the small diameter accommodated part 121 is pulled out to the outside of the accommodation part 20, the large diameter adjustment part 41 and the small diameter adjustment part 42 can be reliably slid by the external force acting on the small diameter harness 120, and the apparent length L of the small diameter harness 120 can be easily adjusted. In this way, by creating a difference in the biasing force between the large diameter spring portion 412 and the small diameter spring portion 422, the lengths of the accommodated portions 101 of the large diameter harness 110 and the small diameter harness 120, which have different diameters, can be reliably adjusted, and the apparent length L can be easily adjusted.

[0132] In the configuration of the present invention and the correspondence between the configuration and the above-mentioned embodiments, the long body of the present invention corresponds to the wire harness 100, the large diameter harness 110, and the small diameter harness 120, The accommodated portions correspond to the accommodated portion 101, the large-diameter accommodated portion 111, and the small-diameter accommodated portion 121, The route corresponds to routes R1 and R2, The housing corresponds to the housing 20, 20x, The path regulation parts correspond to the path regulation parts 30, 30x, the large diameter regulation part 33, and the small diameter regulation part 34. The length adjustment part corresponds to the length adjustment part 40, The imaginary line corresponds to the imaginary line X1, The first direction corresponds to the longitudinal direction X, The cross direction corresponds to the width direction Y, The slide contact portion corresponds to the large diameter sliding portion 411 and the small diameter sliding portion 421, The biasing portion corresponds to the large diameter spring portion 412 and the small diameter spring portion 422, The length adjuster is compatible with the length adjuster 10, 10x. The slide restricting portion corresponds to the adjusting portion restricting body 50, 50x and the through-hole portion 223, 223x, The contact restriction portion corresponds to the protruding piece 218, The first elongated body is adapted to accommodate a large diameter harness, The second elongated body is adapted to accommodate a small diameter harness, The first length adjusting portion corresponds to the large diameter adjusting portion 41, The second length adjusting portion corresponds to the small diameter adjusting portion 42, The insertion portions correspond to the left insertion portion 215 and the right insertion portion 216, The one-side insertion portion corresponds to the left-side insertion portion 215, The first path restriction portion corresponds to the large diameter restriction portion 33, The second path restriction portion corresponds to the small diameter restriction portion 34, The wire harness with length adjuster corresponds to the wire harness with length adjuster 1, 1x, but the present invention is not limited to the configuration of the above-mentioned embodiment, and can be applied based on the technical idea shown in the claims, and many embodiments can be obtained.

[0133] For example, in the present embodiment, the length adjuster 10 is attached to the wire harness 100, but it may also be attached to a hose through which a fluid such as washer fluid or cooling water flows, or to a tube such as a corrugated tube through which the wire harness 100 is inserted. Furthermore, the length adjuster 10 may be attached to the wire harness 100 and the tube.

[0134] Furthermore, in this embodiment, the length adjusters 10, 10x are attached to two wire harnesses, the large diameter harness 110 and the small diameter harness 120, but the length adjuster 10 may be attached to a single elongated body.

[0135] Furthermore, when attaching the length adjuster 10, 10x to a single bundle of elongated bodies obtained by bundling a plurality of elongated bodies, the single bundle of elongated bodies may be branched into multiple pieces, and the length adjuster 10, 10x may be attached to the branched bundle of elongated bodies. More specifically, for example, a highly rigid bundle of elongated bodies may be branched into multiple pieces, and the length adjuster 10, 10x may be attached to the branched bundle of elongated bodies. This makes the branched bundle of elongated bodies less rigid than the bundle of elongated bodies before branching, and therefore the branched bundle of elongated bodies can be easily curved by the length adjuster 10, 10x, and the apparent length of the bundle of elongated bodies can be easily adjusted.

[0136] Alternatively, the bundle of elongated bodies may be branched into elongated bodies with high rigidity and elongated bodies with low rigidity, and the length adjuster 10, 10x may be attached thereto. Specifically, if the bundle of elongated bodies is a bundle of large-diameter harnesses 110 and small-diameter harnesses 120, the bundle may be branched into the large-diameter harnesses 110 and the small-diameter harnesses 120, and the length adjuster 10, 10x may be attached thereto. Furthermore, if the bundle of elongated bodies is a mixture of aluminum wires and copper wires, the bundle may be branched into aluminum wires with high rigidity and copper wires with low rigidity, and the length adjuster 10, 10x may be attached thereto. Furthermore, if the bundle of elongated bodies is a mixture of copper wires and communication cables, the bundle may be branched into copper wires with high rigidity and communication cables with low rigidity, and the length adjuster 10, 10x may be attached thereto.

[0137] In this way, by branching a bundle of long bodies of different rigidity into long bodies of different rigidity and attaching length adjusters 10, 10x, the apparent length of the long body with high rigidity can be adjusted by the large diameter adjustment section 41, while the apparent length of the long body with low rigidity can be adjusted by the small diameter adjustment section 42.

[0138] In addition, in this embodiment, the left side insertion portion 215 is formed at two locations spaced a predetermined distance apart in the width direction Y, but the location at which the left side insertion portion 215 is formed is not limited, and it may be formed at one location or multiple locations. In addition, in this embodiment, the right-side insertion portion 216 is formed in one location in the central part of the width direction Y, but the location where the right-side insertion portion 216 is formed is not limited, and it may be formed in multiple locations.

[0139] Furthermore, although the length adjuster 10 is configured to be able to adjust the apparent lengths L of two wire harnesses 100, it may also be configured to be able to adjust the apparent lengths L of three or more elongated bodies. In this embodiment, the apparent lengths L of the large-diameter harness 110 and the small-diameter harness 120 are adjusted simultaneously, but it is also possible to adjust the apparent length L of one without adjusting the apparent length L of the other, or to adjust the apparent lengths L of one and the other in sequence.

[0140] In this embodiment, the large diameter spring portion 412 and the small diameter spring portion 422 are compression springs, but they may be compression springs, tension springs, leaf springs, rubber, or the like, as long as they can exert a biasing force. In this embodiment, the large-diameter harness 110 and the small-diameter harness 120, which have different diameters, are housed inside the housing sections 20, 20x, but harnesses of the same diameter may be housed, or only one harness may be housed. Also, the large-diameter main wire may be branched inside the housing section 20. In this case, the length adjustment section 40 can be used to reliably bend the main wire, thereby reliably adjusting the length of the housed portion 101.

[0141] In addition, in this embodiment, the apparent length L of the wire harness 100 is adjusted by pulling out the wire harness 100 from the right-side insertion portion 216, but it may be adjusted by pulling out the wire harness 100 from the left-side insertion portion 215. Also, the apparent length L of only one of the large-diameter harness 110 and the small-diameter harness 120 may be adjusted. Furthermore, in this embodiment, the adjuster restrictors 50, 50x are fixed by press-fitting, but any configuration may be used as long as they can be fixed to the accommodating portions 20, 20x, and they may be configured to be lockable or may be welded.

[0142] In addition, in the present embodiment, the apparent length L of the wire harness 100 is adjusted by extending it from the shortest length L1 to the longest length L2, but it may also be adjusted by shortening the apparent length L. Furthermore, the position of the length adjusting part 40 may be adjusted in advance so that the apparent length L of the wire harness 100 to which the length adjuster 10 is attached is between the shortest length L1 and the longest length L2, and the apparent length L may be adjusted to be extended or shortened as necessary.
