On the other side of the inner peripheral surface of the inner peripheral surface or the outer peripheral surface of the inner holding portion, the convex portion and the concave portion which is recessed so as to be lockable may be formed.

According to the present invention, the outer holding portion and the inner holding portion can be reliably locked by the convex portion and the concave portion, so that the branch line protection portion integrally formed with the outer holding portion can be set in a desired direction. It can be locked more securely.

Further, as an aspect of the present invention, a movement adjusting portion for adjusting the movement of the outer holding portion with respect to the inner holding portion in the longitudinal direction may be provided.
According to the present invention, since the position of the branch line protection portion can be adjusted along the longitudinal direction, the arrangement position of the branch line can be adjusted in the longitudinal direction while the trunk line is fixed at a predetermined position.

Further, as an aspect of the present invention, the length of the inner holding portion in the longitudinal direction may be longer than the length of the corresponding outer holding portion.
According to the present invention, the locked state of the outer holding portion can be made more stable.

More specifically, the contact area between the inner holding portion and the outer holding portion that holds the trunk line is smaller than the case where the length of the inner holding portion in the longitudinal direction is shorter than the corresponding length of the outer holding portion. Is increased, so that the locked state of the outer holding portion with respect to the inner holding portion can be stabilized. As a result, when an unexpected force acts on the branch line protection portion, it is possible to prevent the outer holding portion from moving in the circumferential direction.

Further, for example, a convex portion provided on the inner peripheral surface of the outer holding portion is fitted and locked with one of a plurality of concave portions provided side by side in the longitudinal direction on the outer peripheral surface of the inner holding portion. In this case, even if the outer holding portion is moved along the longitudinal direction, the convex portion is fitted into another concave portion provided along the longitudinal direction of the recess in which the convex portion is fitted. It can be stopped. In this way, even when the outer holding portion is moved along the longitudinal direction, the outer holding portion can be locked to the inner holding portion by the locking portion, and the branch line protection portion can be reliably locked. Can be adjusted and fixed in a desired arrangement direction.

Further, as an aspect of the present invention, the outer holding portion may be configured to have a circumferential cross section and may be provided with an opening / closing portion that can be opened and closed.
The cross-sectional circumference refers to a tubular body configured to cover the entire circumference of the trunk line in the circumferential direction. The cross-sectional shape of the tubular body may be any shape such as a circular shape, an elliptical shape, or a rectangular shape.

According to the present invention, the trunk line and the branch line can be easily and surely housed in the branch line protection portion and the trunk line protection portion in an open state. Further, by closing the protector while the trunk line and the branch line are housed, the wire harness can be surrounded by the protector to protect the wire harness, and the branch portion of the branch line can be reliably protected. The branch line can be arranged in a desired direction, and the branch line can be supported.

Further, as an aspect of the present invention, the branch line protection portion may be formed in a diameter-expanded shape in which the diameter increases from the tip end side to the base end side.
According to the present invention, the extra length portion of the branch line can be stored, and when the direction of the branch line protection portion is adjusted to a predetermined direction, the branch portion of the branch line interferes with the branch line protection portion. Since it can be prevented, the load applied to the branch portion of the branch line can be reduced.

Further, as an aspect of the present invention, the tip portion of the branch line protection portion may have flexibility.
According to the present invention, the branch line extending from the tip of the branch line protection portion can be directed in a more desired direction.

More specifically, if there is a discrepancy between the direction in which the branch line protection portion is arranged and the position of electronic devices connected to the branch line, the branch line will be curved and arranged. Since the tip portion of the branch line protection portion has flexibility, the tip end side of the branch line protection portion can be bent along the curve of the branch line, and the branch line can be directed in a more desired direction. The length of the branch line can be shortened.

Furthermore, since the tip portion of the branch line protection portion is also curved along the curvature of the branch line, the branch line has the tip as compared with the case where the tip portion of the branch line protection portion does not have flexibility. By interfering with the opening, the load acting on the branch line can be reduced.

Further, as an aspect of the present invention, a fixing portion for fixing the trunk line protection portion to the trunk line may be provided.

At that time, the branch line 120 branching from the trunk line 110 can be arranged so as to project outward from the insertion space S.

Although the connecting portion 22 connects the lower surface side of the holding portion main body 21, it does not necessarily have to have this configuration. For example, the side surfaces of the holding portion main body 21 may be connected, and the number thereof is also one. Not limited to this, a plurality of connecting portions 22 may be connected, but it is preferable to provide a sufficiently large insertion space S between the holding portion main body 21r and the holding portion main body 21l, and the connecting portion 22 is supported. It is preferable to have a sufficiently open space also in the circumferential direction of the inner holding portion 20.

As shown in FIGS. 3 and 4A, the fitting recess 23 is formed on the outer peripheral surface of the holding portion main body 21 (each of the holding portion main body 21r and the holding portion main body 21l) of the holding portion main body 21. It is a depression having a depth of about one-third of the thickness, and 15 pieces are arranged in the circumferential direction in 5 rows along the longitudinal direction X, for a total of 45 pieces at equal intervals.

As shown in FIGS. 3 and 4A, the fixing portion 24 is an arc-shaped plate-like body extending outward along the longitudinal direction X on the lower side of the holding portion main body 21, and is held by the outer peripheral surface. It is formed so as to be flush with the outer peripheral surface of the main body 21. The outer end of the fixing portion 24 slightly protrudes downward.
As described above, the inner holding portion 20 is formed so that the holding portion main body 21 and the fixing portion 24 are plane-symmetrical with respect to the central surface of the connecting portion 22.

The harness protection portion 30 assembled so as to cover the outer peripheral surface of the inner holding portion 20 is directed from the main body 31 of the trunk line protection portion 31 which is a tubular body and the central portion of the main body of the trunk line protection portion 31 in the width direction Y (−Y direction). It is composed of a branch line protection portion 32 that protrudes vertically, and a fitting convex portion 33 is formed on the inner peripheral surface of the trunk line protection portion main body 31.

The trunk line protection portion main body 31 is a cylindrical body having an inner diameter of the same length as the outer diameter of the holding portion main body 21 and one size shorter than the length of the inner holding portion 20 in the longitudinal direction X, and is divided into two in the vertical direction. It is composed of a trunk line protection unit main body 31u and a trunk line protection unit main body 31d. The trunk line protection unit main body 31u forming the upper half and the trunk line protection unit main body 31d forming the lower half are connected via a hinge 34 provided in the + Y direction, and can be opened and closed mutually with the hinge 34 as a rotation axis. ing.

The branch line protection portion 32 protruding from the central portion of the trunk line protection portion main body 31 in the −Y direction is a substantially cylindrical body whose diameter increases toward the base end side which is a connecting portion with the trunk line protection portion main body 31. Similar to the main body 31 of the trunk line protection unit 31, the branch line protection unit 32u and the branch line protection unit 32d are divided into two in the vertical direction. The branch line protection unit 32u is integrally configured with the trunk line protection unit main body 31u, and the branch line protection unit 32d is integrally configured with the trunk line protection unit main body 31d.

Further, the cylindrical branch line protection portion 32 includes a base end portion 321 which is a connecting portion with the trunk line protection portion main body 31, a branch line protection portion main body 322 extending from the base end portion 321 in the + Y direction, and a branch line. The tip portion 323 extending toward the tip side of the protection portion main body 322 is arranged side by side in this order from the + Y direction to the −Y direction.

The tip portion 323 points in the −Y direction with respect to half of the branch line protection portion 32, and is composed of a member having flexibility as compared with other portions. The tip portion 323 has a length of about half that of the branch line protection portion 32, but this length can be adjusted as appropriate.

Further, inside the branch line protection portion 32, an insertion hole through which the branch line 120 can be inserted is provided along the width direction Y, and the outer diameter of the branch line 120 is at the center of the front end of the branch line protection portion 32 in the front view. An opening 324 having the same inner diameter as that of the above is provided.
The outer diameter of the insertion hole, that is, the inner diameter of the branch line protection portion 32 increases toward the proximal end side. More specifically, the inner diameters of the branch line protection portion main body 322 and the tip portion 323 are configured to be the same as the outer diameter of the branch line 120, but the inner diameter of the proximal end portion 321 increases toward the proximal end side. (See FIG. 5 (c)).

The fitting convex portion 33 is a convex portion that protrudes from the inner peripheral surface of the trunk line protection portion main body 31 toward the inner diameter side by a length substantially equal to the depth of the fitting concave portion 23, and each side portion is squared. There is. The fitting convex portions 33 having such a configuration are provided at equal intervals of 18 along the inner peripheral surface.

Further, the trunk line protection portion main body 31 is lined up in four rows from both outer ends toward the center side in the longitudinal direction X at the same intervals as the rows of the fitting recesses 23. That is, the fitting convex portions 33 are arranged on the inner peripheral surfaces on both outer sides of the trunk line protection portion main body 31, with 18 in each row and 72 in four rows, for a total of 144 pieces, and the trunk line protection portion main body. The fitting convex portion 33 is not provided on the inner peripheral surface of the central portion of the 31 in the longitudinal direction X.

By assembling the protector 10 composed of the inner holding portion 20 and the harness protecting portion 30 configured in this way to the wire harness 100, the branch line 120 can be arranged in a desired direction with respect to the trunk line 110.

Hereinafter, a method of assembling the inner holding portion 20 and the harness protecting portion 30 to the wire harness 100 will be briefly described.
First, a state in which the inner holding portion 20 is assembled to the wire harness 100 will be described with reference to FIG.

The holding portion main body 21 is arranged below the wire harness 100 so that the branch lines 120 are arranged between the holding portion main bodies 21 separated by a predetermined interval, and the trunk line is arranged from the opening provided above the holding portion main body 21. Assemble 110. At this time, since the holding portion main body 21 has elasticity, the opening portion of the holding portion main body 21 expands outward, and the trunk line 110 can be inserted inside the holding portion main body 21.

Further, since the inner diameter of the holding portion main body 21 is smaller than the outer diameter of the trunk wire 110, the trunk wire 110 inserted inside the holding portion main body 21 is surely held by the holding portion main body 21.
The fixing portion 24 and the trunk line 110 are wound around the fixing tape 40 to be fixed, so that the inner holding portion 20 holds the trunk line 110 more firmly.

In the state where the wire harness 100 is assembled to the inner holding portion 20 in this way, the branch line 120 is inserted in the −Y direction from the insertion space S provided between the holding portion main bodies 21. Here, since the insertion space S has a space having a sufficient size with respect to the inner diameter of the branch line 120, there is a sufficient distance between the holding portion main body 21 and the branch line 120. Further, since the connecting portion 22 for connecting the holding portion main bodies 21 to each other is provided on the lower side, a sufficient space is provided in the upward direction of the branch line 120 (see FIG. 6B).

Next, a method of assembling the harness protection portion 30 to the wire harness 100 to which the inner holding portion 20 is assembled will be described.
As shown in FIG. 7A, the wire harness 100 to which the inner holding portion 20 is assembled is arranged above the harness protection portion 30 in the open state so that the branch line 120 is above the branch line protection portion 32. , The wire harness 100 to which the inner holding portion 20 is assembled can be lowered downward and assembled to the harness protection portion 30.

In this state, the fitting recess 23 provided on the longitudinal direction X center side of the outer peripheral surface of the holding portion main body 21 and the fitting convex portion 33 provided on the longitudinal direction X center side of the inner peripheral surface of the trunk line protection portion main body 31. The inner holding portion 20 and the harness protecting portion 30 can be fixed by fitting the two.

Then, the harness protection portion 30 can be closed by rotating the trunk line protection portion main body 31u toward the −Y side with the hinge 34 as the rotation axis. In this state, the branch line 120 is held by the branch line protection unit 32. As shown in FIG. 7B, both ends of the holding portion main body 21 in the longitudinal direction X protrude from both ends of the harness protection portion 30 in the longitudinal direction.

Further, as shown in FIG. 8A, which is a cross-sectional view of the central portion of the protector 10 in the longitudinal direction to which the wire harness 100 is assembled, the base end side of the branch line 120 protruding in the + Y direction and the branch line protection portion 32 ( It is not in contact with the base end portion 321), and a gap is provided.
Further, as shown in FIG. 8B, the fitting concave portion 23 and the fitting convex portion 33 are fitted to each other to lock the inner holding portion 20 and the harness protection portion 30.

In this way, the branch line protection portion 32 of the harness protection portion 30 is locked by fitting the fitting protrusion 33 into the fitting recess 23 with respect to the inner holding portion 20 that holds the wire harness 100. By rotating the central axis of the trunk line 110 as a rotation axis, the arrangement direction of the branch line protection portion 32 with respect to the trunk line 110 can be changed.

Specifically, as shown in FIG. 9A, the branch line protection portion 32 arranged along the −Y direction is rotated 20 degrees counterclockwise with the central axis of the trunk line 110 as the rotation axis. The case will be described.

When the branch line protection portion 32 is arranged along the −Y direction, as shown in FIG. 9B, the fitting convex portion 33 is fitted to the fitting concave portion 23 to form a branch line. The harness protection portion 30 is locked to the inner holding portion 20 so that the protection portion 32 is in the −Y direction.

In this state, when the branch line protection portion 32 is rotated counterclockwise with the central axis of the trunk line 110 as the rotation axis, as shown in FIG. 9C, the fitting convex portion 33 having chamfered corners is formed. , It will ride on the convex portion that separates the adjacent fitting recesses 23 from each other. At this time, since the fitting concave portion 23 is made of an elastic resin and the sides of the fitting convex portion 33 are squared, the fitting convex portion 33 is a bank that more easily separates the fitting concave portion 23. You will be able to ride on top of it.

Further, when the branch line protection portion 32 is rotated upward with the central axis of the trunk line 110 as the rotation axis, as shown in FIG. 9D, the fitting convex portion rides on the convex portion separating the fitting concave portion 23. 33 is fitted with the adjacent fitting recess 23, and the harness protection portion 30 is locked with respect to the inner holding portion 20.

More specifically, as shown in FIGS. 9A and 9B, the fitting convex portion 33b fitted in the fitting recess 23b is a fitting recess 23a and a fitting recess 23b. You can ride on the bank formed between them.

Further, when the branch line protection portion 32 is rotated upward with the central axis of the trunk line 110 as the rotation axis, the fitting convex portion 33b moves counterclockwise to the fitting recess 23a as shown in FIG. 9D. Fit. As a result, the harness protection portion 30 is locked with respect to the inner holding portion 20.

In this way, the branch line protection unit 32 can be adjusted in a desired direction by rotating the branch line protection unit 32 with the central axis of the trunk line 110 as the rotation axis. As a result, the branch line 120 held by the branch line protection unit 32 can be arranged in a desired direction according to the position of the corresponding electronic device or the like.

Similarly, when the harness protection portion 30 is moved along the longitudinal direction X with respect to the inner holding portion 20, the fitting recess 23 adjacent to the fitting recess 23 to which the fitting convex portion 33 fits in the initial state is also obtained. Therefore, the position of the branch line protection portion 32 can be moved along the longitudinal direction X.

Further, the length of the inner holding portion 20 along the longitudinal direction X (the distance between the outer ends of the holding portion main body 21 in the longitudinal direction X) is longer than the length of the trunk line protecting portion main body 31, and the holding portion main body is formed. Since the number of rows of the fitting recesses 23 provided in the 21 is larger than the number of rows of the fitting protrusions 33, even if the harness protection portion 30 is moved along the longitudinal direction X, a certain number of rows are provided. The fitting convex portion 33 can be fitted to the fitting concave portion 23, and the harness protection portion 30 can be fixed to the inner holding portion 20. Thereby, the arrangement position of the branch line 120 can be adjusted along the longitudinal direction X.

Further, since the insertion space S provided between the holding portion main bodies 21 has a sufficient size as compared with the inner diameter of the branch line 120, the branch line is before adjusting the arrangement direction of the branch line protection portion 32. The extra length portion of the branch line 120 can be sufficiently stored, and the extra length portion of the branch line 120 can be pulled out even when the arrangement direction of the branch line protection portion 32 is adjusted.

Furthermore, since the inner diameter of the base end portion 321 increases toward the base end side, there is a gap between the base end portion 321 and the branch line 120. By providing the gap in this way, it is possible to prevent the branch line 120 from interfering with the inner diameter of the base end portion 321 and being damaged even when the wiring direction of the branch line protection portion 32 is changed.

Further, by adjusting the wiring direction of the branch line protection portion 32, the tip of the branch line 120 may be curved toward the electronic device side to which the branch line 120 is connected, but the tip of the branch line protection portion 32 is the tip portion. Since the portion 323 is composed of a member having flexibility as compared with other portions, the portion 323 is curved in accordance with the curvature of the branch line 120 (see FIG. 10).

Therefore, the load applied to the contact portion of the branch line 120 in contact with the opening 324 can be reduced, and the contact portion of the branch line 120 with the opening 324 can be prevented from being damaged.

In this way, the protector 10 that protects the wire harness 100 composed of the trunk line 110 in which a plurality of electric wires are bundled and the branch line 120 branched from the trunk line 110 includes an inner holding portion 20 that protects the trunk line 110 and a trunk line protection. It is composed of a branch line protection portion 31 and a branch line protection portion 32 that protects the branch line 120 and projects in the width direction Y intersecting the longitudinal direction X of the trunk line protection portion main body 31, and defines the branch line protection portion 32. By providing the fitting concave portion 23 and the fitting convex portion 33 for adjusting the arrangement direction of the branch line 120, the arrangement direction of the branch line 120 protected by the branch line protection portion 32 can be adjusted in a desired direction.

Therefore, the wire harness 100 can be protected according to the wiring condition of the wire harness 100 composed of the trunk line 110 and the branch line 120 that is complicatedly branched from the trunk line 110.

Further, the protector 10 is composed of an inner holding portion 20 for holding the trunk line 110 and a harness protecting portion 30 for holding the outer peripheral surface of the inner holding portion 20, and the inner holding portion 20 and the harness protecting portion 30 are arranged in the circumferential direction. A fitting concave portion 23 and a fitting convex portion 33 that are relatively movable and can be locked in a desired direction are provided, and the branch line protection portion 32 is integrally formed with the harness protection portion 30 to form a branch line. The branch line 120 protected by the protection portion 32 can be reliably adjusted in a desired arrangement direction.

Further, since the inner holding portion 20 does not move with respect to the trunk line 110 in accordance with the movement of the harness protection portion 30 in the circumferential direction, the trunk line 110 does not twist due to the movement of the harness protection portion 30 in the circumferential direction. Therefore, by adjusting the arrangement direction of the branch line 120, it is possible to prevent the trunk line 110 from being loaded.

Furthermore, by arranging the inner holding portion 20 from the branch portion of the branch line 120 along both sides in the longitudinal direction X, that is, the inner holding portion 20 sandwiches the branch portion of the branch line 120 in the longitudinal direction X. By being arranged along both sides, the inner holding portion 20 can hold the trunk line 110 more stably, and the harness protecting portion 30 integrally formed with the branch line protecting portion 32 is securely fixed to the trunk line 110. can. Therefore, the branch line protection portion 32 can be reliably adjusted in a desired direction, and the branch line 120 can be reliably arranged in a desired direction.

Further, since the inner holding portion 20 can stably hold the trunk line 110, it is possible to more reliably prevent the inner holding portion 20 from moving in the circumferential direction with respect to the trunk line 110 due to the movement of the harness protection portion 30 in the circumferential direction. .. As a result, it is possible to more reliably prevent the trunk line 110 held by the inner holding portion 20 from being twisted.

Furthermore, the fitting convex portion 33 projects toward the inner holding portion 20 on the inner peripheral surface of the harness protection portion 30, and the fitting concave portion 23 is locked with the fitting convex portion 33 on the outer peripheral surface of the inner holding portion 20. Since it is configured to be recessed as much as possible, the harness protection portion 30 and the inner holding portion 20 can be securely locked by the fitting recess 23 and the fitting convex portion 33, and are integrally configured with the harness protection portion 30. The branch line protection portion 32 can be locked more reliably in a desired direction.

Further, since the fitting concave portion 23 and the fitting convex portion 33 for adjusting the movement of the harness protection portion 30 in the longitudinal direction X with respect to the inner holding portion 20 are provided, the branch line protection portion 32 is provided along the longitudinal direction X. The position can be adjusted, and the arrangement direction of the branch line 120 can be adjusted along the longitudinal direction X with the trunk line 110 fixed at a predetermined position.

Further, by making the length of the inner holding portion 20 along the longitudinal direction X longer than the length of the corresponding harness protecting portion 30, the locked state of the harness protecting portion 30 can be made more stable.

More specifically, the contact area between the inner holding portion 20 holding the trunk line 110 and the harness protecting portion 30 is smaller than the case where the length of the inner holding portion 20 in the longitudinal direction X is shorter than the length of the corresponding harness protecting portion 30. Therefore, the locked state of the harness protection portion 30 with respect to the inner holding portion 20 can be stabilized. As a result, it is possible to prevent the harness protection portion 30 from moving in the circumferential direction when an unexpected force acts on the branch line protection portion 32.

Further, when the fitting convex portion 33 formed on the inner peripheral surface of the harness protection portion 30 is fitted and locked to the plurality of fitting concave portions 23 formed on the outer peripheral surface of the inner holding portion 20. Even if the harness protection portion 30 is moved along the longitudinal direction X, the fitting convex portion 33 can be locked to another fitting recess 23 adjacent to the fitting recess 23 in the longitudinal direction X. In this way, even when the harness protection portion 30 is moved along the longitudinal direction X, the harness protection portion 30 is locked to the inner holding portion 20 by fitting the fitting concave portion 23 and the fitting convex portion 33. Therefore, the branch line protection portion 32 can be adjusted and fixed in a desired arrangement direction.

Further, the harness protection portion 30 is configured to have a circumferential cross section and is provided with a hinge 34 that can be opened and closed, so that the harness protection portion 30u is open to the harness protection portion 30d and the trunk line 110 and the branch line are opened. The 120 can be easily and surely stored in the branch line protection portion 32, the inner holding portion 20, and the trunk line protection portion main body 31. Further, by closing the protector 10 with the trunk line 110 and the branch line 120 housed, the wire harness 100 can be surrounded by the protector 10 to protect the wire harness 100, and the branch portion of the branch line 120 can be reliably protected. The branch line 120 can be arranged in a desired direction and can be supported in a desired direction.

Further, the branch line protection portion 32 is configured to have an enlarged diameter shape in which the diameter increases from the tip end side to the base end side, so that the extra length portion of the branch line 120 can be stored and the direction of the branch line protection portion 32. Is adjusted in a predetermined direction, it is possible to prevent the branch portion of the branch line 120 from interfering with the branch line protection portion 32, so that the load applied to the branch portion of the branch line 120 can be reduced.

Furthermore, since the tip portion 323, which is the tip portion of the branch line protection portion 32, has flexibility, the branch line 120 extending from the tip of the branch line protection portion 32 can be directed in a more desired direction.

More specifically, if there is a discrepancy between the direction in which the branch line protection portion 32 is arranged and the position of electronic devices connected to the branch line 120, the branch line 120 will be curved and arranged. Since the tip portion of the branch line protection portion 32 is flexible, the tip end side of the branch line protection portion 32 can be bent along the curve of the branch line 120, and the branch line 120 can be directed in a more desired direction. At the same time, the length of the branch line 120 can be shortened.

Furthermore, since the tip portion of the branch line protection portion 32 is also curved along the curvature of the branch line 120, the branch line 120 has a tip opening as compared with the case where the tip portion of the branch line protection portion 32 does not have flexibility. The load acting on the branch line 120 can be reduced by interfering with the branch line 120.

Further, since the fixing portion 24 for fixing the inner holding portion 20 to the trunk line 110 is provided, the inner holding portion 20 can be reliably fixed to the trunk line 110. As a result, even when the harness protection portion 30 is rotated in the circumferential direction with respect to the inner holding portion 20, it is possible to prevent the inner holding portion 20 from being pulled by the harness protection portion 30 and rotating.

The convex portion corresponds to the fitting convex portion 33, and corresponds to the fitting convex portion 33.
The recess corresponds to the fitting recess 23 and
The opening and closing part corresponds to the hinge 34,
The present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

For example, the number of the fitting convex portion 33 provided on the inner peripheral surface of the trunk line protection portion main body 31 and the number of the fitting concave portions 23 provided on the outer peripheral surface of the holding portion main body 21 need not be the same as the number of the present embodiment. , The size and the number can be adjusted as appropriate.

Further, the fitting concave portion 23 and the fitting convex portion 33 need not be arranged in a concave manner as long as they can be fitted to each other, and the fitting convex portion fitted to the fitting concave portion 23 does not necessarily have to be arranged. The number of 33 may be reduced.

Furthermore, in the present embodiment, the inner holding portion 20 and the harness protection portion 30 are fixed by fitting the fitting concave portion 23 and the fitting convex portion 33, but such a configuration is not always necessary. For example, it may have a claw shape that locks each other.

Further, in the present embodiment, the harness protection portion 30 is a cylindrical body having a circular cross section configured to cover the entire circumference of the trunk line 110 in the circumferential direction, but the cross section does not have to be circular, for example, an ellipse. It may have any shape such as a shape or a rectangular shape.

Further, the trunk line protection portion main body 31 is composed of a cylindrical body that surrounds the outer peripheral surface of the inner holding portion 20 along the circumferential direction, but it is not always necessary to surround the inner holding portion 20, as shown in FIG. 11, for example. In addition, it may be composed of only the trunk line protection unit main body 31d. In this case, in order to securely fix the trunk line protection portion main body 31d to the inner holding portion 20 and the trunk line 110, the trunk line protection portion main body 31d and the inner holding portion 20 may be fixed with a fixing tape 40 or the like.
In this way, the trunk line protection portion main body 31 may be configured to cover a part of the inner holding portion 20.

Furthermore, the protector 10 may not have the inner holding portion 20 and may be composed only of the harness protecting portion 30.
Specifically, the fitting convex portion 33 is formed in a triangular shape in a side view that can be locked to the trunk line 110, and the branch line protection portion 32 is fitted when the central axis of the trunk line 110 is rotated as a rotation axis. The joint convex portion 33 can be configured to bite into the trunk line 110 and be locked.

Further, instead of the inner holding portion 20, a binding band provided with locking pieces on both sides can be used. By tightly closing the binding band provided with the locking pieces on both sides, one side can bite into the trunk line 110 and hold the trunk line 110. Then, the fitting convex portion 33 provided on the inner peripheral surface of the harness protection portion 30 can be configured to be engageable with the locking piece on the other surface side provided on the binding band. As a result, the harness protection portion 30 can be fixed to the inner holding portion 20, and the harness protection portion 30 can be moved in one direction in the circumferential direction with respect to the inner holding portion 20.

Further, although the inner diameter of the holding portion main body 21 is shorter than the outer diameter of the trunk line 110, it is not always necessary to have such a configuration. For example, the inner diameter of the holding portion main body 21 is smaller than the outer diameter of the trunk line 110. It doesn't matter if it's big. In this case, in order to securely fix the inner holding portion 20 and the trunk line 110, it is preferable to securely fix the fixing tape 40 or the like by wrapping the fixing tape 40 or the like around the fixing portion 24.

Furthermore, in the configuration in which the branch line protection portion 32 is adjusted in a predetermined arrangement direction, the branch line protection portion 32 is arranged with respect to the inner holding portion 20 as in the fitting recess 23 and the fitting convex portion 33. In addition to the configuration in which the branch line protection unit 32 is rotated around the central axis of the trunk line as the installation direction, as shown in FIG. 12, the anchor 60 for fixing the protector 10 to the vehicle 200 or the like is fixed. A plurality of portions 50 are provided on the outer peripheral surface of the harness protection portion 30 at equal intervals (9 in FIG. 12), and the protectors 10 are arranged and anchors are attached so that the branch line protection portions 32 have a desired angle. Therefore, the arrangement direction of the branch line protection portion 32 can be adjusted (see FIG. 12B).
