Electrical equipment equipped to improve the operability and comfort of automobiles is electrically connected to batteries, etc. via wire harnesses, and signals are transmitted and received, and power is supplied. .. The wire harness for connecting the electric devices in this way is arranged in the vehicle body by accommodating a part of the wire harness in the protector and fixing it to the vehicle body.

Further, a corrugate is fixed to the protector insertion port so that the wire harness does not interfere with the protector insertion port and is damaged, and the wire harness is inserted through this corrugate. At this time, the corrugate is inserted from the protector insertion slot to a predetermined position so that the corrugate does not come out of the protector insertion slot.

For example, the protector disclosed in Patent Document 1 is provided with a positioning portion for abutting the tip of the corrugated portion on a wire insertion portion for fixing the corrugate and inserting a wire harness, and a wire through a hole through which the positioning portion can be visually recognized. By providing it on the bottom surface of the insertion portion, it is said that it is possible to visually confirm that the corrugated portion is inserted to a predetermined position in the wire insertion portion.

However, in the protector disclosed in Patent Document 1, since the positioning portion is provided on the insertion port side of the through hole, the field of view from the through hole is blocked by the positioning portion, and the tip of the corrugate and the positioning portion are separated from each other. It was difficult to visually check whether they were in contact with each other. Therefore, it was not possible to confirm that the corrugated was inserted to the predetermined position.

In view of the above problems, it is an object of the present invention to provide a protector and a protector with a wire harness that can surely confirm that the corrugated piece is inserted to a predetermined position.

The present invention is a protector that internally accommodates a wire harness inserted into a bellows-structured corrugate in which a ridge portion that rises in the outer peripheral direction and a groove portion that dents in the inner peripheral direction are alternately arranged along the longitudinal direction. It has a corrugated fixing portion for fixing the corrugate and an insertion port into which the end of the corrugated is inserted, and a wire insertion portion for inserting the wire harness is provided inside. An insertion confirmation unit for confirming from the outside that the corrugated has been inserted to a predetermined position is provided, and the insertion confirmation unit includes a contact portion that abuts on the outer peripheral surface of the corrugate inserted from the insertion port to a predetermined position. It is characterized in that it is composed of a moving support portion that movably supports the contact portion to the outside so that it can be confirmed from the outside.

Further, in the present invention, a wire harness inserted into a bellows-structured corrugate in which a raised portion raised in the outer peripheral direction and a groove portion recessed in the inner peripheral direction are alternately arranged along the longitudinal direction, and an end portion of the corrugated portion are inserted. It is composed of a protector having an insertion port to be inserted and a wire insertion portion for inserting the wire harness inside, and the corrugated portion is inserted into the wire insertion portion from the insertion port to a predetermined position. An insertion confirmation unit for confirming from the outside is provided, and the insertion confirmation unit can confirm the contact portion that abuts on the outer peripheral surface of the corrugate inserted to a predetermined position from the insertion port and the corresponding contact portion from the outside. It is characterized in that it is a protector with a wire harness composed of a moving support portion that movably supports the outside.

The raised portion and the groove portion may form an uneven shape along the longitudinal direction, and the height of the raised portion, the depth of the groove portion, and the shapes of the raised portion and the groove portion are not particularly limited. That is, the raised portion may be configured to be raised in the outer peripheral direction from the groove portion, and similarly, the groove portion may be configured to be recessed in the inner peripheral direction from the raised portion.

The contact portion has a structure in which the contact portion with the corrugate is flat, or a structure in which the contact portion with the corrugate protrudes toward the inside of the wire insertion portion or is recessed toward the outside. Includes a configuration that can be fitted to the raised portion and the groove portion in the corrugated portion.

The term "contacting with the outer peripheral surface" means that the contact portion abuts on the raised portion or the groove portion of the corrugated, and not only when the abutting portion simply contacts the outer peripheral surface of the corrugated portion, but also on the abutting portion. Includes the case where is fitted with the groove portion or the raised portion.
The moving support portion includes, for example, a configuration in which the abutting portion is supported so as to slide, a configuration in which the abutting portion is supported so as to translate from the inside to the outside of the wire insertion portion, and the like.

The above-mentioned confirmation from the outside means to confirm the contact portion visually or by force. For example, the contact portion configured to be flush with the surface constituting the wire insertion portion may come into contact with the outer peripheral surface of the corrugate so as to project to the outside of the wire insertion portion, or the wire. When the contact portion arranged inside the insertion portion abuts on the outer peripheral surface of the corrugate, it becomes flush with the surface constituting the wire insertion portion, or projects to the outside of the wire insertion portion. It means that the contact portion can be visually confirmed and tentacle confirmed. Further, the contact portion closes all or a part of the through hole provided so that the inside of the wire insertion portion can be visually recognized, and the inside of the wire insertion portion can be visually recognized or tentacled from the through hole. It means that the contact portion can be visually confirmed or visually confirmed from the outside by moving the contact portion to the outside.

According to the present invention, it can be surely confirmed that the corrugated piece is inserted to a predetermined position.
More specifically, by inserting the corrugated to a predetermined position, the abutting portion in contact with the outer peripheral surface of the corrugated portion moves to the outside of the wire insertion portion. Thereby, the contact portion can be visually confirmed or visually confirmed by a tentacle from the outside, and it can be surely confirmed that the corrugated portion is inserted to a predetermined position of the wire insertion portion.

Further, for example, even when the protector is assembled to the vehicle body and the contact portion is arranged in a position where it cannot be visually observed, or even when the protector is installed in a dark place, the contact portion can be confirmed by tentacles. Therefore, it is possible to confirm whether or not the corrugated is inserted to a predetermined position without removing the protector from the vehicle body.

As an aspect of the present invention, the wire insertion portion is provided with a through hole penetrating the outside and the inside, and the moving support portion has the contact portion internally arranged so as to correspond to the through hole. It may be supported so as to be movable up to the through hole.
The term "arranged inside so as to correspond to the through hole" means that the protector is arranged at a position corresponding to the position of the through hole, for example, the contact portion is said to be the same. When the contact portion is arranged so as to be movable toward the through hole by being pivotally supported by the edge portion forming the through hole, or when the contact portion is arranged facing the through hole. , It means that the contact portion is arranged so as to be movable with respect to the through hole.

Movable to the above-mentioned through hole means that the abutting portion can be moved so as to be flush with the surface constituting the wire insertion portion forming the through hole, or the abutting portion can be moved to the through hole. This includes cases where the wire can be as close as possible by visual inspection or by tentacles.

According to the present invention, since the contact portion in contact with the outer peripheral surface of the corrugate moves to the through hole, the contact portion can be confirmed from the through hole. Therefore, it can be surely confirmed that the corrugated is inserted to a desired position.
Further, when the contact portion moves to the through hole, the through hole is at least partially closed by the contact portion, so that foreign matter can enter the inside of the wire insertion portion from the through hole. Can be prevented.

Furthermore, since the abutting portion moves to the through hole, that is, the abutting portion does not project to the outside of the through hole, for example, a space for arranging another device outside the protector. Can be secured and the appearance can be improved.

Further, as an aspect of the present invention, the contact portion may be smaller than the shape of the through hole.
The above-mentioned smaller than the shape of the through hole means that, for example, when the through hole has a rectangular shape, the corresponding length corresponds to at least one of the longitudinal direction and the lateral direction of the through hole. The length of the contact portion may be short. It should be noted that the shapes of the through hole and the contact portion do not have to be similar to each other.

INDUSTRIAL APPLICABILITY According to the present invention, a gap can be provided between the contact portion and the through hole, and when the contact portion excessively enters the inner side, the contact is made through the through hole. The portion can be returned to a position where it properly abuts on the corrugated.

Further, as an aspect of the present invention, the protector is composed of a protector main body formed with a concave cross section by a bottom surface portion and side wall portions on both sides, and a lid portion covering the opening, and the bottom surface portion or the lid of the protector main body.

The side wall portion refers to a side wall erected on both ends of the bottom surface portion. When the side wall portion is erected from both ends in the width direction intersecting the longitudinal direction in the bottom surface portion, or when it is erected inside the both ends of the bottom surface portion, one of the side surfaces thereof is erected in the width direction. This includes the case where the other side is erected at one end and the other side is erected inside the other end.

According to the present invention, since the through hole can be easily provided in the wire insertion portion, the workability can be improved and the manufacturing cost can be reduced.
Further, when the protector is attached to the vehicle body, one of the lid portion and the bottom surface portion is a surface that comes into contact with the vehicle body side. That is, since the other side of the lid portion or the bottom surface portion is arranged so as to face the outside of the vehicle body, the through hole and the moving support portion are provided on the other side so as to be attached to the vehicle body. However, it can be easily and surely confirmed whether or not the corrugated corrugated portion is inserted to a predetermined position.

Further, as an aspect of the present invention, the contact portion may be provided at a position corresponding to the raised portion of the corrugated portion or the circular apex portion of the groove portion in the mounting direction in which the lid portion is mounted on the protector main body. good.

According to the present invention, the height of the contact portion can be lowered, so that the rigidity of the contact portion can be increased. This makes it possible to prevent the contact portion from being damaged due to contact with the corrugate.
In addition, it is possible to prevent the contact portion from moving due to contact with the outer peripheral surface of the corrugate that is not intended.

Further, as an aspect of the present invention, the moving support portion may be supported by the wire insertion portion and may be provided with a pivot support portion for pivoting the contact portion.
According to the present invention, the contact portion can be pivoted to the outside of the wire insertion portion with a simple configuration.

Further, in a state where the contact portion is not in contact with the corrugate, the inclination of the contact portion with respect to the wire insertion portion becomes large. On the other hand, when the contact portion comes into contact with the corrugate, the contact portion is pivoted and the inclination with respect to the wire insertion portion is reduced. In this way, by pivoting the contact portion, the change in the contact portion that can be confirmed from the outside of the wire insertion portion becomes clear, so that the contact portion can be confirmed more reliably visually or by tentacles. Therefore, it can be confirmed more reliably that the corrugated has been arranged to a predetermined position.

Further, as an aspect of the present invention, the moving support portion may be configured to be connected to one end side of the plate-shaped connecting portion, and the contact portion may be provided on the other end side of the connecting portion.
According to the present invention, the moving width of the contact portion provided on the other end side of the connecting portion can be increased. That is, since the amount of change of the contact portion with the outer peripheral surface of the corrugate before and after contact can be increased, the contact portion can be more reliably confirmed visually or by tentacles. Therefore, it is possible to more reliably confirm that the corrugate is inserted to a predetermined position.

Further, as an aspect of the present invention, the connecting portion may have a trapezoidal shape in which one end side is wider than the other end side.
According to the present invention, it is possible to improve the strength of one end side of the connecting portion provided with the pivot portion.

Further, as an aspect of the present invention, the contact portion is provided on the proximal end side of the wire harness inserted from the insertion port in the insertion direction, and the pivot portion is inserted from the insertion port of the wire harness. It may be provided on the tip side in the insertion direction.

According to the present invention, since the contact portion can be provided on the insertion port side, the length of the corgate to be extra-inserted is shortened in order to confirm whether the corrug is inserted to a predetermined position. Can be done. Therefore, it is possible to prevent the corrugated length from becoming unnecessarily long, and it is possible to reduce the weight.

Further, as an aspect of the present invention, the contact portion may be configured by a fitting portion that fits into the raised portion or the groove portion.
According to the present invention, since the contact portion can be stably moved to the outside, it can be confirmed that the corrugated portion has been inserted to a predetermined position more reliably.

In order to accommodate the wire harness 100 in the protector 2, the wire harness 100 inserted through the corrugated 200 is deformed according to the shape of the protector main body 10. That is, the wire harness 100 is accommodated in the harness accommodating portion 30, and the main harness 110 and the sub harness 120 are deformed so as to be inserted in accordance with the shapes of the main insertion portion 40 and the sub insertion portion 50.

Next, the −X direction end of the main corrugate 210 comes into contact with the positioning portion 44, and the grooves of the main corrugate 210 and the sub corrugate 220 are fitted into the main side fixing rib 43 and the sub side fixing rib 53. The positions of the main corrugated 210 and the sub corrugated 220 are adjusted, and the deformed and position-adjusted wire harness 100 is fitted into the protector body 10 from above.

After the wire harness 100 inserted through the corrugated 200 is fitted into the protector main body 10, the lid portion 20 is lowered from above so as to close the upper opening portion of the protector main body 10, and the locked portion 13 and the lid side are closed. The lid portion 20 is fixed to the protector main body 10 by locking the locking portion 23.
As a result, the protector 1 with a wire harness can be manufactured by assembling the wire harness 100 inserted through the corrugate 200 to the protector 2.

In the protector 1 with a wire harness manufactured in this manner, as shown in FIG. 7, the main corrugate 210 is inserted into the main insertion portion 40 so that the tip of the main corrugate 210 abuts on the positioning portion 44, and the protector 1 is inserted into the main insertion portion 40. The groove portion 212 is fitted with the main side fixing rib 43.

Further, when the outer peripheral surface of the main corrugated 210 and the protruding portion 731 come into contact with each other, the support plate 71 and the fitting portion 73 are pivotally moved toward the −Z direction with the hinge portion 72 as the pivot shaft, and the support plate 71 and the protrusions are formed. The support portion 732 is arranged so as to be flush with the bottom surface 41 of the main insertion portion. As a result, the support plate 71 and the fitting portion 73 can partially close the through hole 60.

By visually observing the through hole 60 closed in this way, the fitting portion 73 can be confirmed from the outside, and by touching the through hole 60, the fitting portion 73 closing the through hole 60 can be confirmed. It can be confirmed that the corrugated 210 is arranged in a predetermined position.

More specifically, in the protector 2 in which the wire harness 100 is not inserted through the main insertion portion 40, as shown in FIGS. 5 and 6, the insertion confirmation portion 70 is the tip end portion (−X direction side end portion) of the support plate 71. ) Is arranged inside the main insertion portion 40, so that the support plate 71 is bent inward of the main insertion portion 40 with the hinge portion 72 as an axis. Therefore, the inside of the main insertion portion 40 can be visually recognized from the through hole 60.

By accommodating the wire harness 100 in such a protector 2, more specifically, the main corrugated 210 arranged so that it can be inserted to a predetermined position with respect to the main insertion portion 40 can be inserted from the + Z direction to-. By moving it in the Z direction, the outer peripheral surface of the main corrugated 210 comes into contact with the protruding portion 731. As a result, the fitting portion 73 pivotally rotates with the hinge portion 72 as the pivot axis, and the fitting portion 73 pivotally moves downward.

Then, the main corrugated 210 is inserted to a predetermined position in the main insertion portion 40, that is, the tip of the main corrugated 210 is in contact with the positioning portion 44, and the groove portion 212 is fitted to the main side fixing rib 43. The protrusion 731 fits into the groove 212, and the protrusion support 732 is flush with the bottom surface 41 of the main insertion portion to partially close the through hole 60.

Since the through hole 60 is partially blocked by the fitting portion 73 in this way, the fitting portion 73 (projection support portion 732) can be visually or visually confirmed through the through hole 60, and the main corrugated 210 is located at a predetermined position. It can be surely confirmed that the main insertion portion 40 is inserted up to.
Since the fitting portion 73 is arranged at the central portion in the width direction Y on the bottom surface 41 of the main insertion portion, the protruding portion 731 comes into contact with the lower circular apex portion of the groove portion 212.

On the other hand, as shown in FIG. 8, for example, when the main corrugated 210 is not inserted to a predetermined position, the outer peripheral surface and the protruding portion 731 of the main corrugated 210 are inserted when the main corrugated 210 is inserted from above. The support plate 71 does not pivot with the hinge portion 72 as the pivot axis, and the protrusion support portion 732 may close the through hole 60 as shown in FIG. 8 (b). No.

Therefore, the inside of the main insertion portion 40 can be visually recognized from the through hole 60, and it can be confirmed that the through hole 60 is not blocked by touching the through hole 60. This makes it possible to recognize that the main corrugated 210 has not been inserted to a predetermined position.

Since the height of the protrusion 731 is the same as the depth of the groove of the groove 212, that is, the height of the protrusion 731 is made as low as possible, the height of the protrusion 731 is different from that of the groove 212 to which the protrusion 731 fits. It is possible to prevent contact and fitting.

As described above, the wire harness 100 inserted into the main corrugated 210 having a bellows structure in which the raised portion 211 raised in the outer peripheral direction and the groove portion 212 recessed in the inner peripheral direction are alternately arranged along the longitudinal direction X is housed inside. The protector 2 has a main side fixing rib 43 for fixing the main corrugated 210 and a main insertion port 45 into which an end portion of the main corrugated 210 is inserted, and a main insertion portion 40 for inserting the wire harness 100 is provided inside. The main insertion portion 40 is provided with an insertion confirmation unit 70 for confirming from the outside that the main corrugated 210 has been inserted to a predetermined position from the main insertion port 45, and the insertion confirmation unit 70 is provided at a predetermined position from the main insertion port 45. The fitting portion 73 that abuts on the outer peripheral surface of the main corrugated 210 and the fitting portion 73 that abuts on the outer peripheral surface of the main corrugated 210 are supported, and the fitting portion 73 that abuts on the outer peripheral surface of the main corrugated 210 can be confirmed from the outside. Since it is composed of the hinge portion 72 that supports it so as to be movable outward, it can be surely confirmed that the main corrugated 210 is inserted to a predetermined position.

More specifically, by inserting the main corrugated 210 to a predetermined position, the fitting portion 73 in contact with the outer peripheral surface of the main corrugated 210 moves outward. By visually confirming the fitting portion 73 that has moved outward in this way from the outside or by tentacles, it is possible to reliably confirm that the main corrugated portion 210 is inserted to a predetermined position of the main insertion portion 40.

Further, the main insertion portion 40 is provided with a through hole 60 penetrating the outside and the inside, and the hinge portion 72 supports the fitting portion 73 arranged inside so as to correspond to the through hole 60, and the main corrugate. By supporting the fitting portion 73 in contact with the outer peripheral surface of the 210 so as to be movable up to the through hole 60, the fitting portion 73 can be confirmed from the through hole 60. Therefore, it can be surely confirmed that the main corrugated 210 is inserted to a desired position.

Further, when the fitting portion 73 moves to the through hole 60, the through hole 60 is at least partially closed by the fitting portion 73, so that foreign matter can enter the inside of the main insertion portion 40 from the through hole 60. Can be prevented.

Furthermore, since the fitting portion 73 moves to the through hole 60 and is flush with the bottom surface 41 of the main insertion portion, that is, the fitting portion 73 does not protrude to the outside of the through hole 60, for example, the protector 2 It is possible to secure a space for arranging other devices on the outside of the and improve the appearance.

Further, by making the fitting portion 73 smaller than the shape of the through hole 60, a gap can be provided between the fitting portion 73 and the through hole 60. As a result, when the fitting portion 73 excessively enters the inner side, the fitting portion 73 can be returned to a position where it correctly abuts on the main corrugate 210 through the through hole 60.

Further, the protector 2 is composed of a protector main body 10 formed with a concave cross section by a bottom surface portion 11 and side wall portions 12 on both sides, and a lid portion 20 covering the opening, and the bottom surface portion 11 (bottom surface of the main insertion portion) in the protector main body 10. By providing the through hole 60 and the insertion confirmation portion 70 in the 41), the through hole 60 can be easily provided in the main insertion portion 40, so that the workability can be improved and the manufacturing cost can be reduced.

Further, when the protector 2 is attached to the vehicle body, one of the lid portion 20 or the bottom surface portion 11 is a surface that comes into contact with the vehicle body side. That is, since the other side of the lid portion 20 or the bottom surface portion 11 is a surface to be arranged toward the outside of the vehicle body, the vehicle body is provided with the through hole 60 and the hinge portion 72 on the other side of the lid portion 20 or the bottom surface portion 11. It is possible to easily and surely confirm whether the main corrugated 210 is inserted to a predetermined position even when it is attached to the main corrugated gate 210.

Further, the fitting portion 73 is provided at a position corresponding to the peak portion of the raised portion 211 or the groove portion 212 of the main corrugated 210 in the mounting direction in which the lid portion 20 is mounted on the protector main body 10, so that the fitting portion 73 is provided. The height of the fitting portion 73 can be lowered, and the rigidity of the fitting portion 73 can be increased. This makes it possible to prevent the fitting portion 73 from being damaged when it comes into contact with the main corrugated 210.

Further, since the hinge portion 72 is supported by the main insertion portion 40 and can pivot the fitting portion 73, the fitting portion 73 can be pivoted to the outside of the main insertion portion 40 with a simple configuration.

Further, in a state where the fitting portion 73 is not in contact with the main corrugate 210, the inclination of the fitting portion 73 with respect to the main insertion portion 40 (main insertion portion bottom surface 41) becomes large. On the other hand, when the fitting portion 73 comes into contact with the main corrugate 210, the fitting portion 73 pivots and the inclination with respect to the main insertion portion 40 (main insertion portion bottom surface 41) becomes small. By pivoting the fitting portion 73 in this way, the change in the fitting portion 73 that can be confirmed from the outside of the main insertion portion 40 becomes clear, so that the change can be confirmed more reliably by visual inspection or by tentacles. Therefore, it can be confirmed more reliably that the main corrugated 210 is arranged to a predetermined position (see FIGS. 7 and 8).

Furthermore, the hinge portion 72 is connected to one end side of the plate-shaped support plate 71, and the fitting portion 73 is connected to the other end side of the support plate 71, whereby the other end side of the support plate 71 is connected. The moving width of the fitting portion 73 provided in the above can be increased. As a result, the amount of change of the fitting portion 73 before and after contact with the outer peripheral surface of the main corrugated 210 can be increased, and it can be confirmed more reliably that the main corrugated 210 is inserted to a predetermined position.
Further, since the support plate 71 has a trapezoidal shape whose one end side (-X direction) is wider than that of the other end side, the strength of the one end side of the support plate 71 provided with the hinge portion 72 can be improved.

Further, the fitting portion 73 is provided on the base end side (+ X direction side) of the wire harness 100 inserted from the main insertion port 45 in the insertion direction (longitudinal direction X), and the hinge portion 72 is inserted from the main insertion port 45. Since the fitting portion 73 can be provided on the insertion port side by being provided on the tip side (-X direction side) of the wire harness 100 to be inserted, is the main corrugate 210 inserted to a predetermined position? In order to confirm that, the length of the main corrugated 210 to be inserted extra can be shortened. Therefore, it is possible to prevent the main corrugated 210 from becoming unnecessarily long, and it is possible to reduce the weight.

Further, since the fitting portion 73 is configured to be fitted to the groove portion 212, the fitting portion 73 can be stably moved downward (on the −Z direction side), so that the fitting portion 73 can be moved more reliably. It can be confirmed that the main corrugated 210 has been inserted to a predetermined position.

The insertion slot corresponds to the main insertion slot 45,
The wire insertion part corresponds to the main insertion part 40,
The contact portion corresponds to the fitting portion 73 and corresponds to the fitting portion 73.
The mobile support and pivot correspond to the hinge 72 and
The connecting portion corresponds to the support plate 71,
The present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

For example, in the present embodiment, the through hole 60 and the insertion confirmation portion 70 are provided on the bottom surface 41 of the main insertion portion, but it is not always necessary to provide the through hole 60 and the insertion confirmation portion 70 on the bottom surface 41 of the main insertion portion. It may be provided on the upper surface portion 21 corresponding to 40.

If the bottom surface 41 of the main insertion portion is a surface to be attached to the vehicle body side, the upper surface portion 21 is arranged on the outside. Therefore, by providing the through hole 60 and the insertion confirmation portion 70 in the upper surface portion 21, the protector 1 with a wire harness can be provided. Even when assembled to the vehicle body, it can be surely confirmed that the main corrugated 210 is inserted to a predetermined position.

Further, in the present embodiment, the through hole 60 and the insertion confirmation portion 70 are provided only in the main insertion portion 40, but of course, they may be provided in the sub insertion portion 50.
Furthermore, although the main insertion portion 40 in the present embodiment is provided with the positioning portion 44, the positioning portion 44 is not always indispensable, and even in a state where the positioning portion 44 is not provided like the sub insertion portion 50. By providing the through hole 60 and the insertion confirmation portion 70, it can be surely confirmed that the main corrugate 210 is inserted to a predetermined position.

Further, in the present embodiment, the fitting portion 73 is provided at the + X direction side end portion of the support plate 71 extending from the hinge portion 72 connected to the −X direction side edge portion of the through hole 60, for example. As shown in FIG. 10, a fitting portion 73 may be provided at the −X direction side end portion of the support plate 71 extending from the hinge portion 72 connected to the + X direction side edge portion of the through hole 60.

That is, in the present embodiment, the fitting portion 73 is provided on the main insertion port 45 side with respect to the hinge portion 72, but as shown in FIG. 10, the fitting portion 73 is fitted on the positioning portion 44 side with respect to the hinge portion 72. A portion 73 may be provided.

According to this embodiment, even if an external force acts on the main corrugated 210 toward the + X direction, the fitting portion 73 fitted to the groove 212 in the main corrugated 210 is pivoted upward (+ Z direction side). It will move, and it is possible to prevent the main corrugated 210 from coming off in the + X direction.

Further, in the present embodiment, the fitting portion 73 is configured to be fitted with the groove portion 212 of the main corrugated portion 210, but it is not always necessary to have this configuration, for example, the main corrugated portion 210 in the fitting portion 73. The contact portion that comes into contact with the outer peripheral surface may be configured to be flat, or the contact portion in the fitting portion 73 may be configured to be recessed so as to be matable with the raised portion 211. However, by configuring the fitting portion 73 to fit with the groove portion 212, the pivoting fitting portion 73 is guided to a position where the fitting portion 73 fits along the side wall of the raised portion 211, so that the fitting portion 73 is securely fitted. The portion 73 and the groove portion 212 can be fitted.

Further, the fitting portion 73 may be configured to abut on the raised portion 211 of the main corrugated 210 in addition to abutting on the groove portion 212.
Further, as shown in the present embodiment, in addition to the hinge portion 72 that supports the fitting portion 73 so as to slide, the fitting portion 73 is translated from the inside to the outside in the main insertion portion 40. It may be a supportive configuration.

Further, in the present embodiment, the outer surface of the protrusion support portion 732 is a flat surface, but for example, by increasing the plate thickness in whole or in part, the main corrugated 210 is inserted to a predetermined position. The protrusion support portion 732 may be configured to protrude to the outside of the bottom surface 41 of the insertion portion. Thereby, the fitting portion 73 can be confirmed more reliably visually or by force.
A step may be created by making the plate thickness of the protrusion support portion 732 thinner than that of the bottom surface 41 of the main insertion portion.

Further, although the shape of the insertion confirmation portion 70 is smaller than that of the through hole 60, for example, the length of at least one side in the longitudinal direction X or the width direction Y should be shortened with respect to the rectangular through hole 60. Therefore, a gap may be created between the through hole 60 and the insertion confirmation portion 70.
Further, the through hole 60 does not have to have a rectangular shape, and its shape can be appropriately changed such as a circular shape, an elliptical shape, or an oval shape.
