The wire harness that connects these electronic devices includes, for example, a main harness that constitutes a main circuit and a sub-harness that constitutes other circuits.

  Generally, since the sub-harness is routed along the same route as the main harness, when the wire harness is routed, the sub-harness corresponding to an additional function is routed after the main harness is routed. Route along the harness. Various protectors that protect the main harness and hold the sub-harness in consideration of such a routing procedure have been devised.

  For example, Patent Document 1 proposes a protector that includes a hook-shaped base material that protects the main harness, and a holding portion that protrudes outward from the outer surface of the side wall of the base material and holds the sub-harness. Yes.

  The protector described in Patent Document 1 will be described in detail. The holding portion which is formed in a U shape and includes a locked portion, and the locked portion of the holding portion is locked at the upper end of the side surface. The base member provided with the locking part is connected to the base member via a thin hinge part, and in a state where the holding part is rotated with the hinge as a fulcrum, the locked part provided in the holding part and the The locking portion on the outside of the holding portion is locked.

A wire harness attachment method for attaching a wire harness to a storage space of a protector, and a step of attaching a main harness, which is a main harness of the wire harnesses, to a base material of the storage space, and a regulation provided on the side portion Partitioning the storage space into a main harness space for storing the main harness at a portion, and regulating the main harness;
Partitioning the storage space, regulating the main harness, attaching an additional sub-harness of the wire harness to the open side of the storage space, and covering the cover material The step of attaching to the base is performed in this order.

The base material includes a case where the bottom surface portion and the side surface portion are integrally formed and a case where the bottom surface portion and the side surface portion are formed separately.
Further, the cross-sectional shape of the base body need not be limited to a specific shape. For example, when the cross-sectional shape is a substantially concave shape with an open top surface or an arc shape, the cross-sectional shape of the bottom surface is U-shaped. And the case where it is V-shaped, and also includes the case where the heights of the opposing wall surfaces are different.

  The cover material may have any shape as long as it covers the opening surface of the base material. For example, when the cover material lays the upper surface of the side surface portion having the same height, the cover material is opposite to the bottom surface portion. The case where it protrudes to the upper surface side used as the side, the case where it protrudes to the bottom surface side, etc. are included. Moreover, the case where the cross-sectional shape of the said cover material is reverse concave shape, circular arc shape, etc. is included.

  The wire harness is a main harness which is a first wire harness housed in the main harness space which is the first layer, and a second wire harness which is housed in the sub harness space which is the second layer. Refers to a configuration that consists of a harness. For example, when the main harness is composed of a wire harness that is routed in a main circuit and the sub harness is connected to an electronic device that is added according to a vehicle type, specifications, or the like, Including a wire harness that is routed in a main circuit and a wire harness that is connected to an electronic device to which the main harness is added.

The main harness and the sub-harness include a covered electric wire in which a conducting wire that conducts an electric line is covered with an insulating resin, a bundle of the covered electric wires, and the sub-harness accommodated in the sub-harness space includes a communication wire For example, when the sub-harness is not routed to the instrument panel, a cooling water transport tube or the like is included.

  To divide the storage space described above means to divide the storage space into a main harness space in which the main harness is arranged and a sub harness space in which the sub harness is arranged.

Specifically, the storage space is completely divided into the main harness space and the sub-harness space by the restriction portion that is a planar body along the bottom surface of the base material, or the restriction portion is By partially disposing the base material along the bottom surface of the base material, the storage space is partitioned so that the main harness space and the sub harness space are opened in a place where the base material is not disposed. Including doing.
In the case where the storage space is partially divided, the number is not limited to a specific number.

  The restricting portion includes a configuration in which the side portions facing each other and a configuration in which the side portion is provided between the side portions and the bottom portion. The shape of the restricting portion is a flat plate-like body or a plate having a circular cross section. It includes a body, an elastic body such as a string body and rubber.

According to the present invention, the main harness and the sub-harness can be separated and stored in the same storage space with a simple structure.
More specifically, by providing the restriction portion, the storage space can be divided into the main harness storage space for storing the main harness and the sub harness storage space for storing the sub harness. Thereby, after attaching the base material to the main harness and partitioning the storage space, the sub-harness can be stored in the sub-harness storage space. That is, the main harness and the sub-harness can be stored separately in the same storage space with a simple structure in which the restriction portion is provided.

  The restricting portion is configured to delimit the storage space on the upper surface side of the bottom surface portion and to restrict the base material disposed on the base body from being separated from the harness. With this configuration, for example, the main harness can be moved in a state where the protector is attached in order to route the sub-harness at another work place.

As an aspect of the present invention, the storage space may be an in-base storage space formed by the bottom surface portion and the side surface portion.
The storage space in the base refers to the storage space provided in the base material composed of the bottom surface portion and the side surface portion. That is, the cover material forms the upper surface of the base material and does not form the storage space.

  According to this invention, the main harness and the sub-harness can be stored in the storage space in the base. In other words, the main harness and the sub-harness can be accommodated at a position lower than the side surface portion, and the main harness and the sub-harness attached to the base material are prevented from being easily separated from the base material. it can.

As an aspect of the present invention, the restricting portion may be provided in the vicinity of both side end portions in the wiring direction in which the wire harness is routed.
The vicinity of both end portions in the wiring direction in which the wire harness is routed refers to the vicinity of the opening portion of the protector in a state where the cover material is attached to the base material. That is, it refers to a predetermined range along the side surface portion from a position where the wire harness arranged on the protector leads.

According to this invention, it can prevent more reliably that the said main harness leaves | separates from the said base material.
More specifically, since the main harness is generally high in rigidity, when an external force is applied to the main harness derived from the cover material, the main harness disposed in the opening portion is easily separated from the base material. .

  However, according to the present invention, since the restricting portion is provided in the vicinity of the end that is the opening portion, for example, even if a force acts on the main harness, the main harness is more reliably separated from the base material in the opening portion. Can be prevented.

  Accordingly, for example, the main harness can be more reliably prevented from being separated from the base material due to vibration during transportation, and the attachment work for attaching the main harness to the protector, and the attachment work for attaching the sub-harness to the protector. Can be done at a remote location. That is, the main harness can be moved with the protector attached to route the sub-harness at another work place.

  Moreover, since it can prevent that the said base material leaves | separates from the said main harness, the damage of the said main harness and protector by the said main harness interfering with another member can be prevented.

  Furthermore, as an aspect of the present invention, the restricting portion is configured by a plate-like restricting plate that spans between the side portions facing each other, and a plurality of the restricting plates route the wire harness. It can be characterized by being arranged along.

  The above construction means that the restriction plate straddles between the side portions facing each other, but the end portion of the restriction plate is not necessarily in contact with the outer wall side of the side portion, for example, the end of the restriction plate The structure which fixes a part and the inner wall side of the said side part may be sufficient.

  The term “along the line of intersection between the bottom surface portion and the side surface portion” means that the crossing portion of the bottom surface portion and the side surface portion is along the intersection. In other words, it means along the wire harness arranged in the storage space formed by the bottom surface portion and the side surface portion.

  According to the present invention, for example, even when an unintended external force acts on the wire harness, the plurality of restriction plates can regulate the wire harness.

  In addition, for example, when the restriction plate is a single piece, the sub harness falls into the bottom surface side due to its own weight, i.e., the main harness storage space, in a place where the restriction plate is not disposed. By providing a plurality of restriction plates, a virtual restriction surface passing through the plurality of restriction plates is formed, and the sub-harness can be prevented from falling into the main harness storage space.

  Accordingly, the sub-harness can be supported at a plurality of locations, the sagging of the sub-harness can be prevented, and the sub-harness having an appropriate length can be efficiently routed along a desired routing route.

  Furthermore, as an aspect of the present invention, the facing side surface portion is provided with a recessed portion that penetrates in the thickness direction and is recessed on the bottom surface portion side, and the recessed portion that faces the regulating portion is bridged. It can be.

  According to this invention, since the restriction portion is configured to be fitted into the recess, the restriction portion can be reliably assembled at a desired position. Therefore, the assembling of the restricting portion is facilitated and workability can be improved.

  Moreover, when attaching the said cover material to the said base material after attaching the said wire harness to the said accommodation space, interference with the said control part and the said cover material can be prevented. For this reason, it is not necessary to make the said cover material into a complicated structure, and it is not necessary to newly install a cover material, and cost can be reduced.

Furthermore, since the cover material is independent of the restricting portion, the cover material can be processed according to the purpose of use of the protector. For example, when the side surface portion of the cover material covers the restriction portion and the concave portion, the dustproof property and the waterproof property can be improved. Furthermore, since the inside cannot be seen from the outside, the external shape can be made an integrated design.
On the other hand, when the side surface portion of the cover material is processed into a shape that does not cover the restricting portion and the recess, the inside can be visually confirmed from the outside, so that the internal state can be easily confirmed.

Furthermore, as an aspect of the present invention, the restricting portion may include a restricting portion fixing means that is fixed to the side surface portion.
The restricting portion fixing means includes a fixing means for fixing the restricting portion and the side surface portion, and a temporary fixing means capable of releasing the fixation after fixing. Moreover, the said restriction | limiting part fixing means includes the case where it is provided in one when it is provided in both the said side parts.

  The fixing and temporary fixing methods may be any method as long as they can be fixed or temporarily fixed. For example, the restriction portion or the side surface portion is locked by a locking portion such as a hook and a corresponding locked portion. And the case of fixing with tape, string, rubber or the like.

  According to the present invention, the main harness can be more reliably regulated, and the regulating portion can further prevent the main harness from being detached. For example, even when an unintended external force is applied during transportation, the base body can be transported with the base body securely attached to the main harness.

  Further, for example, when the restricting portion fixing means is a temporary fixing means, a position where the main harness is easily detached can be temporarily fixed, and therefore the base material can be easily attached to the main harness.

  Furthermore, as an aspect of the present invention, the restricting portion and the side portion are integrally formed, and the restricting portion is pivotally supported on the side portion so as to pivot about one end side of the restricting portion. Supporting means may be provided, and the restricting part fixing means may be configured to fix the restricting part pivoted about the pivoting means in a erected state.

  According to the present invention, the base member and the restricting portion are connected by the pivoting operation of the restricting portion around the pivot supporting means by providing the pivot supporting means for connecting the base material and the restricting portion. Can be stopped. Therefore, for example, the restricting portion and the base material can be fixed with one hand, and the workability of attaching the main harness can be improved.

  Furthermore, a harness fixing part for fixing the main harness arranged on the base material can be provided on the base material.

  The harness fixing portion may have any configuration as long as the harness can be fixed to the base material. For example, the harness fixing portion is wound together with a hole for passing a binding band around which the wire harness is wound and fixed, a double-sided tape, rubber, a string, or the like. Including a fixed part to be fixed.

  According to the present invention, it is possible to more firmly restrict the main harness from being separated from the base material.

In other words, it is provided at a location where the opening and the attached wire harness bend or change the angle.

As shown in FIGS. 6 and 7, the restricting portion 35 is a plate-like body in which the concave portion 34 and one end side in the width direction W are connected to each other, and includes a restricting plate 351, a pivotal support portion 352, a temporary fixing locking portion 353 It is comprised integrally with.
The restriction plate 351 has a length in the longitudinal direction L, that is, the width of the restriction plate 351 is slightly smaller than the width of the concave portion 34, and the distance in the width direction W is smaller than the distance between the side portions 32 facing each other. Has a slightly longer shape.

  As shown in FIG. 7, the pivotal support portion 352 is a hinge provided at the end on the back side of the restriction plate 351 and is connected to the upper surface of the recess 34. For this reason, the restricting portion 35 can pivot about the pivot portion 352 that is a connecting portion with the recess 34.

As shown in FIG. 7B, the temporary fixing / locking portion 353 integrally includes a temporary fixing / locking support portion 353a and a temporary fixing / locking protrusion 353b.
The temporarily fixed locking support portion 353a is a plate-like body that is lowered substantially vertically downward from the front end portion of the restriction plate 351 in a state where the restriction plate 351 is horizontal with the base material bottom surface portion 31a, and has a lower end side central portion A temporarily fixed locking protrusion 353b having a substantially triangular cross section protruding outward is protruded.

  The temporarily fixed locking protrusion 353b is a protruding portion having a substantially triangular cross section that tapers downward in a state where the restricting plate 351 is horizontal with the base material bottom surface portion 31a, and the upper surface is parallel to the restricting plate 351. The lower end portion has a rounded shape.

As shown in FIGS. 6 and 7, the temporarily fixed locked frame 36 is a locking frame that protrudes in the front direction in the width direction W from the side surface portion 32 located at the lower end portion of the recess 34.
More specifically, the temporarily fixed locked frame 36 has two locked frames that protrude outward along the side surface portion 32 at a predetermined interval as shown in FIGS. 5B and 7. 361 and the to-be-latched surface 362 which constructs the upper end part of the to-be-latched frame 361 are comprised integrally.

  The length in the height direction H of the frame to be locked 361 is substantially equal to the length in the height direction H of the temporarily fixed locking portion 353, and the length in the width direction W is the same as the length in the width direction W of the temporarily fixed locking portion 353. It is almost equal to the length. Also, the length in the height direction Z of the locked surface 362 erected between the locked frames 361 is longer than the length from the upper end of the temporarily fixed locking support portion 353a to the upper surface of the temporarily fixed locking protrusion 353b. It is a short length. That is, the upper surface of the temporarily fixed locking projection piece 353b is engaged with the bottom surface of the locked surface 362 in a state where the regulation plate 351 is level with the base material bottom surface portion 31a.

  The interval between the locked frames 361, that is, the width of the locked surface 362 is slightly larger than the width of the temporarily fixed locking portion 353, and the side surface portion 32, the locked frame 361, and the locked surface 362 The temporary fixing locking portion 353 can be inserted.

  Similarly to the temporarily fixed locked frame 36, the cover fixing frame 37 includes two cover side locked frames 371 and a cover side locked surface 372 for erection of the upper end portion of the cover side locked frame 371. The cover-side locked frame 371 is formed so that the interval between the cover-side locked frames 371 is slightly larger than the width of the cover-locking piece 23. The bottom surface of the stop surface 372 is configured to engage with the top surface 233 of the cover locking piece 23 (see FIGS. 3 and 5B).

  The base material 30 having such a configuration forms a storage space S in which the wire harness 100 is accommodated by the bottom surface portion 31 and the side surface portion 32. Further, the storage space S can be divided into a main storage space M formed below and a sub-harness space O formed above by locking the restricting portion 35 to the temporarily fixed locked frame 36. Yes (see FIG. 9).

  Next, the attachment method which attaches the wire harness 100 to the protector 10 is demonstrated based on FIG.8 and FIG.9.

  First, as shown in FIG. 6, each regulating portion 35 is opened, and the buckle 41 of the binding band 40 is passed through each through hole 39. At this time, the binding band 40 is passed through the through hole 39 so that the band 42 is arranged at the position of the through hole 391 for arranging the buckle.

  Next, as shown in FIG. 9A, the main harness 200 is disposed at a desired position on the bottom surface portion 31 (step s1). At this time, the main harness 200 is disposed on the back side in the base material front end portion 30f, but the position of the main harness 200 disposed on the back side is regulated by the base material bottom surface portion 31a and the front end side locking auxiliary surface portion 31b. It will be.

  At the same time, the position of the main harness 200 disposed in the base material central portion 30c is also regulated by the base material bottom surface portion 31a and the central locking auxiliary surface portion 31c, and the portion disposed in the base material rear end portion 30r is also the base material bottom surface. The position restriction inspection is performed by the portion 31a and the rear end side locking auxiliary surface portion 31d (not shown). Therefore, by using the base material 30, the position of the main harness 200 can be regulated to a desired shape.

  Next, as shown in FIG. 9A, the main harness 200 arranged at a desired position is fixed to the base member 30 with the binding band 40 (step s2). Thereby, the main harness 200 arrange | positioned in a desired position can be fixed more reliably, for example, even when an external force acts, it can prevent leaving from the base material 30 easily.

  At this time, the through hole 39 can be accommodated in the base material 30 by arranging the buckle 41 so as to be located in the through hole 39 formed at the intersection of the base material bottom surface portion 31 a and the side surface portion 32. That is, it is possible to prevent the through hole 39 from protruding outward (see FIG. 9).

  Then, as shown in FIG. 9B, the restricting portion 35 is pivoted around the pivot portion 352 so that the restricting plate 351 is horizontal with the base material bottom surface portion 31 a, and provided on the front side of the restricting portion 35. The temporarily fixed locking portion 353 and the locked surface 362 are locked and temporarily fixed (step s3). In this way, the main harness 200 is restrained from above by the restricting portion 35, thereby restricting the main harness 200 from being separated from the base material 30.

  Further, by this division, the ratio of the main harness storage space M occupied by the main harness 200 is 75% of the cross-sectional area of the storage space S, and the cross-sectional area occupied by the main harness 200 with respect to the cross-sectional area of the main harness space M is 70%. For this reason, the main harness storage space M has sufficient play with respect to the cross-sectional area of the main harness 200, and even if an external force acts on the main harness 200, the main harness 200 can escape to the play portion. Even if an external force is applied to the harness 200, no load is applied to the main harness 200.

  Then, as shown in FIG. 9C, four bundles of sub-harnesses 300 are arranged on the temporarily fixed locked frame 36 and the three restriction portions 35 temporarily fixed (step s4). At this time, since the restricting portion 351 that is a configuration of the three restricting portions 35 temporarily fixed to the temporarily fixed locked frame 36 forms a restricting surface, the sub harness 300 is prevented from falling into the main harness space M due to its own weight. Can be arranged in a desired shape.

  After the sub-harness 300 is disposed on the upper surface of the restriction surface formed by the restriction portion 35 in this way (step s4), as shown in FIG. 9D, the cover fixing frame 37 constituting the base material 30 is covered with the cover material. The cover material 20 and the base material 30 are assembled and fixed so that the 20 cover locking pieces 23 engage (step s5). At this time, since the lower surface of the lid upper surface portion 21 is formed in an arc shape, even when the sub harness 300 interferes with the lower surface of the lid upper surface portion 21, it can escape into the play space of the lid upper surface portion 21, and The cross-sectional area of the harness storage space O can be increased, and many sub-harnesses 300 can be stored.

Finally, the sub harness 300, the main harness 200, and the harness fixing portion 33 are wound with the tape 400 to fix the wire harness 100 and the protector 10 (see FIG. 1).
The protector 10 can be attached to the wire harness 100 by storing the main harness 200 and the sub-harness 300 in the storage space according to the above procedure.

  As described above, the base material 30 composed of the side surface portion 32 and the bottom surface portion 31 extending from both ends of the bottom surface portion 31 in the width direction, and the cover material 20 that covers the opening surface formed on the upper surface side of the base material 30. Is a protector 10 having a storage space S for storing the wire harness 100 formed by the cover material 20 and the base material 30, and on the side surface portion 32 on the bottom surface portion 31 side with respect to the cross-sectional area of the storage space S. The storage space S is stored so that the cross-sectional area ratio of the cross-sectional area to be formed, that is, the cross-sectional area of the main harness storage space M is 75%, and the main harness storage space M for storing the main harness 200 and the sub-harness 300 are stored. By dividing into the sub-harness storage space O and having a regulation part 35 for regulating the wire harness 100 arranged on the bottom side, A main harness 200 and the sub-harness 300 can be accommodated by separation in the same storage space S at prime to structure.

  More specifically, the storage space S can be divided into a main harness storage space M for storing the main harness 200 and a sub-harness storage space O for storing the sub-harness 300 by providing the restricting portion 35. Thus, after the base material 30 is attached to the main harness 200 and the storage space S is divided by the restricting portion 35, the sub harness 300 can be stored in the sub harness storage space O. That is, the main harness 200 and the sub-harness 300 can be stored separately in the same storage space S with a simple structure in which the restriction portion 35 is provided.

  The restricting portion 35 is configured to divide the storage space S on the upper surface side of the bottom surface portion 31 and restrict the base material 30 disposed on the base body from being separated from the harness. With this configuration, for example, the main harness 200 can be moved with the protector 10 attached to route the sub-harness 300 at another work place.

In addition, the restriction portion 35 is configured so that the cross-sectional area of the main harness storage space M is 75% of the cross-sectional area of the storage space S, so that the cross-sectional area ratio of the main harness 200 with respect to the cross-sectional area of the main harness storage space M is set. When the main harness 200 is attached to the protector 10, play can be provided in the space of the main harness 200. Accordingly, even when an external force is applied to the main harness 200, it is difficult to apply a load to the main harness 200, and the main harness 200 can be disposed on the base material 30 with a margin.
Therefore, the attachment work for attaching the main harness 200 to the base member 30 can be facilitated.

  At the same time, since the ratio of the cross-sectional area of the sub-harness 300 to the cross-sectional area of the sub-harness storage space O can be less than 70%, the sub-harness 300 can be easily attached in the same manner as the main harness 200. A case where a harness 300 is further added can be dealt with.

  Further, by forming the storage space S with the bottom surface portion 31 and the side surface portion 32, the main harness 200 and the sub harness 300 can be stored in the in-base storage space S. In other words, since the sub harness 300 accommodated in the sub harness accommodation space O does not protrude above the accommodation space S, the main harness 200 and the sub harness 300 attached to the base material 30 are easily separated from the base material 30. Can be prevented.

  In the present embodiment, the cover material 20 is configured to form the upper surface of the base material 30, but is not limited to this configuration. For example, when the cover material 20 protrudes upward, The cover member 20 may have an arc shape in cross section.

  Furthermore, by providing the restricting portion 35 in the vicinity of both end portions in the wiring direction in which the wire harness 100 is routed, the base material 30 can be more reliably prevented from separating from the main harness 200.

  More specifically, since the main harness 200 has a configuration in which a plurality of covered electric wires are bundled, the rigidity is high, and when an external force acts on the main harness 200 led out from the cover member 20, the main harness 200 disposed in the opening portion is It is easy to leave the base material 30.

  However, according to the present invention, since the restricting portion 35 is provided at the base material front end portion 30f and the base material rear end portion 30r that are the opening portions, even if an external force is applied to the main harness 200, the main harness 200 is formed at the opening portion. It is possible to prevent the separation from 30 more reliably.

  Thereby, for example, the main harness 200 can be more reliably prevented from being separated from the base material 30 due to vibrations during transportation, and the attachment work for attaching the main harness 200 to the protector 10 and the attachment work for attaching the sub harness 300 to the protector 10. Can be done at a remote location. That is, in order to route the sub-harness 300 at another work place, the main harness 200 with the protector 10 attached can be moved.

  Moreover, since it can prevent that the main harness 200 leaves | separates from the base material 30, damage to the main harness 200 by the main harness 200 interfering with another member can be prevented.

  Furthermore, the regulation part 35 is comprised by the plate-shaped regulation board erected between the side parts 32 which face, and the several regulation part 35 is arrange | positioned along the wiring direction which routes the wire harness 100. FIG. Thus, even when an unintended external force acts on the wire harness 100, the plurality of restricting portions 35 can restrict the wire harness 100.

  Further, for example, when the plate-like restricting portion 35 is a single piece, the sub harness 300 falls into the bottom portion 31 side, that is, the main harness storage space M due to its own weight at a place where the restricting portion 35 is not disposed. However, by providing a plurality of restricting portions 35 formed in a plate shape, a virtual restricting surface passing through the plurality of restricting portions 35 is formed, and the sub-harness 300 falls into the main harness storage space M. Can be suppressed.

  As a result, the sub-harness 300 can be supported at a plurality of locations, the sagging of the sub-harness 300 can be prevented, and the sub-harness 300 having an appropriate length can be efficiently routed along the desired routing route.

  Further, the facing side surface 32 is provided with a recessed portion 34 that penetrates in the thickness direction and is depressed on the bottom surface portion 31 side, and the recessed portion 34 that the restricting portion 35 faces is bridged. Since it can be set as the structure fixed by fitting in the recessed part 34, the control part 35 can be assembled | attached to a desired position reliably. Therefore, assembly of the restricting portion 35 is facilitated, and workability can be improved.

  In addition, when the cover member 20 is attached to the base member 30, interference between the restricting portion 35 and the cover member 20 can be prevented. For this reason, it is not necessary to make cover material 20 into a complicated structure, and it is not necessary to newly install cover material 20, and cost can be reduced.

  Furthermore, since the restricting portion 35 includes the temporarily fixed locking portion 353 and the temporarily fixed locked frame 36 that are fixed to the side surface portion 32, the main harness 200 can be more reliably restricted. However, the detachment of the main harness 200 can be further prevented. Thereby, for example, even when an unintended external force is applied during transportation, the base body can be transported with the base body securely attached to the main harness 200.

  Further, for example, when the temporarily fixed locking portion 353 and the temporarily fixed locked frame 36 are used as the temporary fixing means, a position where the main harness 200 is easily detached can be temporarily fixed. Therefore, the base material 30 is attached to the main harness 200. Easy to install.

  In this embodiment, the restricting portion 35 and the side surface portion 32 are temporarily fixed by the temporarily fixed locking portion 353 and the temporarily fixed locked frame 36. However, the method of fixing the restricting portion 35 and the side surface portion 32 is also described. Any method may be used, and includes, for example, a case where locking is performed by a locking portion such as a hook and a corresponding locked portion, and a case where fixing is performed using tape, string, rubber, or the like.

Furthermore, the regulation part 35 and the side part 32 are integrally formed, and a pivotal support part 352 for pivoting the regulation part 35 on the side part 32 so as to pivot about one end side of the regulation part 35 is provided. The fixed locking portion 353 is configured such that the restriction portion 35 pivoted around the pivot portion 352 is fixed in a state of being laid so as to straddle the concave portion 34, so that the restriction portion 35 having the pivot portion 352 as the center is fixed. The base member 30 and the restricting portion 35 can be locked by the turning operation.
Therefore, for example, the restricting portion 35 and the base material 30 can be fixed with one hand, and the workability of attaching the main harness 200 can be improved.

  Furthermore, a provisional support portion 352 is provided, and a concave portion 34 provided on the side surface portion 32 facing the restricting portion 35 is erected, and a temporarily fixed locked frame 36 provided outwardly of the side wall portion 32 and temporarily fixedly locked By adopting a configuration in which the portion 353 is locked and temporarily fixed, there is no need to provide a temporary fixing means or the like inside the side surface portion 32, and the volume of the storage space S can be secured. Accordingly, the wire harness 100 can be prevented from being damaged by the temporary fixing means while securing the volume of the storage space S in which the wire harness 100 is accommodated.

  Further, the base material 30 is provided with a through hole 39 for fixing the main harness 200 disposed on the base material 30, and the main harness 200 is fixed by a binding band 40 that penetrates the through hole 39, thereby allowing the main harness to be fixed. It can control more firmly that 200 leaves | separates from the base material 30. FIG.

  In the present embodiment, the main harness 200 disposed in the base material 30 is fixed using the through hole 39, but is limited to the through hole 39 provided for fixing the main harness 200 disposed in the base material 30. For example, it may be a fixing portion that is wound and fixed together with tape, rubber, string, or the like that winds and fixes the main harness 200.

In correspondence between the configuration of the present invention and the above-described embodiment,
The fixing means corresponds to the temporarily fixed locking portion 353 and the temporarily fixed locked frame 36,
The pivot means corresponds to the pivot section 352,
The fixing portion corresponds to the through hole 39,
The present invention is not limited only to the configuration of the above-described embodiment, and many embodiments can be obtained.

  For example, in the present embodiment, the temporary fixing locking portion 353 and the temporary fixing locked frame 36 are temporary fixing means that can be fixed and released after the regulating portion 35 and the side surface portion 32 are fixed. For example, a fixing means for fixing the restricting portion 35 and the side surface portion 32 may be used.

  However, by making the fixing by the temporary fixing locking portion 353 and the temporary fixing locked frame 36 temporary fixing, there is an effect that the protector 10 can be reused when the main harness 200 is replaced.

  In addition, the temporary fixing locking portion 353 and the temporary fixing locked frame 36 are provided on one side, but the shape is not limited to this shape. It is good also as a structure which provides the fixed latching frame 36 and is temporarily fixed by both the side parts 32. FIG.

Furthermore, in the present embodiment, the restricting portion 35 is configured to construct the opposing side surface portion 32, but may be configured to construct between the side surface portion 32 and the bottom surface portion 31.
Furthermore, in the present embodiment, the restricting portion 35 is a plate-like body, but it is only necessary to be able to partition the storage space S and restrict the main harness 200, and it is not necessarily a flat plate-like body. Other examples of the restricting portion 35 may be, for example, a plate-like body having a circular cross section, an elastic body such as a string body or rubber.

Furthermore, since the cover material 20 is independent of the regulation plate 35, the cover material 20 can be processed according to the purpose of use of the protector 10. For example, when the side surface portion of the cover material 20 covers the regulation plate 35 and the recess 34, the dustproof property and the waterproof property can be improved. Furthermore, since the inside cannot be seen from the outside, the external shape can be made an integrated design.
On the other hand, when the side surface portion of the cover material 20 is processed into a shape that does not cover the regulation plate 35 and the recess 34, the inside can be visually confirmed from the outside, so that the internal state can be easily confirmed.
