Is described.

By the way, in such a slit, since the movement in the direction perpendicular to the longitudinal direction of the wire harness (insertion member) is allowed, if the movement amount is too large, the wire harness may interfere with other members, There is a risk of being bitten by the member. That is, it is desirable to stably maintain the position of the insertion member inserted through the insertion hole.
JP 2006-282127 A

  In view of the above facts, an object of the present invention is to obtain a vehicle body structure capable of stably maintaining the position of the insertion member inserted through the insertion hole.

  In the first aspect of the present invention, the insertion member is inserted and an insertion hole that allows movement in a direction intersecting the longitudinal direction of the insertion member is formed, and the first plate-like member constituting the vehicle body, A second plate member attached to the one plate member so as to cover the insertion hole when viewed in the thickness direction of the first plate member, and at least one of the first plate member and the second plate member And a movement range limiting means that is provided on one side and contacts the insertion member outside the insertion hole to limit the movement range of the insertion member.

  In the present invention, the insertion member is inserted through the insertion hole of the first plate-like member constituting the vehicle body. The insertion hole is allowed to move in a direction orthogonal to the longitudinal direction of the insertion member.

  A second plate member is attached to the first plate member. This 2nd plate-shaped member has covered the penetration hole seeing in the thickness direction of the 1st plate-shaped member. Therefore, it is possible to prevent the foreign matter from passing through the insertion hole carelessly.

  Further, at least one of the first plate member and the second plate member is provided with a movement range limiting means. The movement range limiting means limits the movement range of the insertion member by contacting the insertion member outside the insertion hole. Therefore, the insertion member is allowed to move in the direction perpendicular to the longitudinal direction at the portion inserted through the insertion hole, and the movement range is limited outside the insertion hole, that is, at the portion where the movement range limiting means is in contact. . Thereby, the position of the insertion member inserted through the insertion hole can be stably maintained.

  According to a second aspect of the present invention, in the first aspect of the present invention, the movement range limiting means is attached to the first plate member, and the insertion member is inserted between the first plate member. It is a movement restriction sheet which restrict | limits the movement range of an insertion member by comprising the insertion part.

  Therefore, the movement range of the insertion member is limited by the insertion portion configured between the first plate-like member and the movement restriction sheet, and the position can be stably maintained. Since the movement restricting sheet is simply attached to the first plate-like member, the structure is simple.

  In invention of Claim 3, in invention of Claim 1 or Claim 2, the said 2nd plate-shaped member is provided with the sticking part for sticking to said 1st plate-like member, Said The movement range limiting means is constituted by the sticking part.

  Therefore, the range of movement of the insertion member can be limited and the position can be stably maintained by effectively utilizing the sticking part for sticking the second plate-like member to the first plate-like member. Since a new member for limiting the movement range of the insertion member is unnecessary, the number of parts does not increase.

  The invention according to claim 4 is characterized in that, in the invention according to claim 3, the sticking portion is formed at a position covering the insertion hole as viewed from above the second plate-like member. To do.

  Thus, by allowing the sticking portion to cover the insertion hole from above, it is possible to suppress the intrusion of water droplets or the like through the insertion hole.

  According to a fifth aspect of the invention, in the first aspect of the invention according to any one of the first to fourth aspects, the first plate member covers a hole formed in an inner panel of the vehicle door. It is a part cover, the insertion member is a wire harness for sharing electric power inside the vehicle door, and the insertion hole is a slit formed in the hole cover and through which the wire harness is inserted. The second plate-like member is a sub-sheet adhered to the hole cover so as to cover the slit of the hole cover.

  In the present invention, the hole formed in the inner panel of the vehicle door is covered with the hole cover, but the hole cover is formed with an insertion hole. Moreover, in this invention, the wire harness which supplies electric power to the inside of a vehicle door is provided, and this wire harness is penetrated by the slit formed in the hole cover. Further, the sub-sheet attached to the hole cover covers the slit of the hole cover.

  And in this way, in the vehicle door provided with the wire harness, the position of the wire harness inserted through the slit can be stably maintained.

  Since this invention set it as the said structure, the position of the penetration member penetrated by the penetration hole can be maintained stably.

  FIG. 1 partially shows a door structure 12 according to an embodiment of a vehicle body structure of the present invention. In the drawings, the front side of the vehicle is indicated by an arrow FR, the upper side is indicated by an arrow UP, and the outer side in the vehicle width direction is indicated by an arrow OUT.

  This door structure 12 includes an inner panel 14 and a hinge side panel 16 that constitute a vehicle door (the whole image is not shown). Various electrical components such as a window regulator are arranged between the inner panel 14 and an outer panel (not shown), and power supply to these electrical components and transmission / reception of control signals are performed by the wire harness 18. Yes. Hereinafter, a direction orthogonal to the longitudinal direction of the wire harness 18 is referred to as a “lateral direction”.

  A service hole 20 is formed in the inner panel 14 and is normally closed by a service hole cover 22. The service hole cover 22 is formed with a slit 24 substantially horizontally along the vehicle front-rear direction.

  A sub sheet 26 is attached to the service hole cover 22 from the outside in the vehicle width direction. As shown in detail in FIG. 2, the sub-sheet 26 has a shape (rectangular shape in the present embodiment) that covers the slit 24, and a flat inverted U-shaped weld portion 28 is set on the upper portion. Yes. The sub-sheet 26 is partially welded at the welded portion 28 so as to be adhered to the service hole cover 22. In particular, the welded portion 28 is set to be watertight at a position covering the slit 24 when viewed from above the sub-sheet 26. Thus, water droplets or the like that have flowed down on the outer side in the vehicle width direction are prevented from entering the inner side in the vehicle width direction through the slit 24.

  As can be seen from FIG. 3, the wire harness 18 extending from the vehicle front side is inserted into the slit 24. That is, when the wire harness 18 is traced from the vehicle front side toward the rear side, the wire harness 18 passes from the lower side between the sub-seat 26 and the service hole cover 22 to the upper side, and comes out from the slit 24 to the inner side in the vehicle width direction. The wire harness 18 is movable in the vehicle front-rear direction within the range of the slit 24.

  As shown in FIGS. 1 and 2, a sub-sheet 30 is attached to a surface on the inner side in the vehicle width direction of the service hole cover 22 at a position obliquely above the sub-sheet 26 and on the vehicle rear side. In this embodiment, the sub-sheet 30 is formed in a rectangular shape, and is welded to the service hole cover 22 by two welding portions 32 provided so as to be parallel to the two end sides. The orientation of the welded portion 32 is set so as to be substantially parallel to the extending direction of the wire harness 18 in the vicinity of the sub-sheet 30. An insertion portion 34 through which the wire harness 18 is inserted is configured between the two welded portions 32 and between the service hole cover 22 and the sub-sheet 30. That is, the movement of the wire harness 18 in the lateral direction is restricted by inserting the wire harness 18 through the insertion part 34.

  In the door structure 12 of the first embodiment having such a configuration, the wire harness 18 is inserted through the slit 24 of the service hole cover 22. The slit 24 is set so as to be covered with a sub-sheet 26 attached to the service hole cover 22 and to be watertight at a position where the welded portion 28 covers the slit 24. Thus, water droplets or the like that have flowed down on the outer side in the vehicle width direction are prevented from entering the inner side in the vehicle width direction through the slit 24.

  The wire harness 18 is partially inserted through an insertion portion 34 formed between the service hole cover 22 and the sub seat 30 on the vehicle rear side with respect to a portion inserted through the slit 24. Thereby, the movement to the horizontal direction of the wire harness 18 is restrict | limited. For example, in the configuration without the sub-sheet 30, the wire harness 18 may be greatly displaced as indicated by a two-dot chain line 18A in FIG. 4, but in this embodiment, the wire harness 18 is largely displaced in this way. In addition, the position of the wire harness 18 can be stably maintained (moving between the two dash-dot lines ME). In addition, since the sub-sheet 30 is simply attached to the service hole cover 22, the structure is not complicated and a simple structure is sufficient.

  In the first embodiment, the movement restriction sheet (sub-sheet 30) is taken as an example of the movement range restriction device of the present invention. However, the movement range restriction device is formed in a sheet shape as described above. It is not limited to a thing, For example, a string-like thing may be sufficient.

  FIG. 5 partially shows the door structure 52 according to the second embodiment of the present invention. Below, only a different point from 1st embodiment is demonstrated, the same code | symbol is attached | subjected about the same component, a member, etc., and detailed description is abbreviate | omitted.

  In the door structure 52, the sub-sheet 30 is not provided as compared with the door structure 12 of the first embodiment. Further, the shape of the welded portion 54 of the sub-sheet 26 is different from the shape of the welded portion 28 of the first embodiment.

  That is, as shown in detail in FIG. 6, the welded portion 54 according to the second embodiment includes a flat inverted U-shaped portion like the welded portion 28 of the first embodiment. On the vehicle rear side, it extends obliquely downward and to the vehicle front side. The diagonally extending portion 54L has an action of restricting the movement of the wire harness 18 in the lateral direction.

  In the door structure 52 of the second embodiment having such a configuration, the movement range of the wire harness 18 is limited by the extended portion 54 </ b> L of the weld portion 54. In particular, the lower end of the extended portion 54L is a point that restricts the movement of the wire harness 18. For example, in the configuration without the extended portion 54L, the wire harness 18 may be greatly displaced as shown by two-dot chain lines 18B and 18C in FIG. In the present embodiment, as indicated by the alternate long and short dash line 18D in FIG. 6, even if the wire harness 18 tries to be displaced in the lateral direction, the displacement is limited by hitting the extension portion 54L (in practice, in the vicinity of the extension portion 54L). Since the gap between the service hole cover 22 and the sub-seat 26 is narrow, the wire harness 18 is placed in the lateral direction so as to be sandwiched between the service hole cover 22 and the sub-seat 26 before contacting the extension portion 54L. The displacement is often limited).

  In particular, in the second embodiment, the movement of the wire harness 18 in the lateral direction is limited by partially extending the welded portion 54 set to attach the sub-sheet 26 to the service hole cover 22. That is, in the second embodiment, the sticking portion 54 is effectively used, and the sub-sheet 30 of the first embodiment is not necessary, so the number of parts is further reduced. Further, even when it is impossible or difficult to dispose the sub-sheet 30 of the first embodiment in relation to other members, it can be easily applied.

  Of course, it is also possible to use a configuration in which the sub-sheet 26 is attached to the service hole cover 22 by the welded portion 54 having the extended portion 54L of the second embodiment and a configuration in which the sub-sheet 30 is provided.

  In each of the above embodiments, as a configuration for attaching the sub-sheets 26 and 30 to the service hole cover 22, an example in which the sub-sheets 26 and 30 are partially welded by the welding portion 28 is given as an example. The structure for attaching the sub-sheet to the cover is not limited to this. For example, as shown in FIG. 7, the sub sheet 26 may be attached to the service hole cover 22 with a double-sided adhesive tape 56. Furthermore, the sub-sheets 26 and 30 may be attached to the service hole cover 22 using, for example, rivets or hooks. However, the sub-sheet 26 is also required to have an action of covering the slit 24 and suppressing the water that has flowed down from the upper side from reaching the slit 24. From this point of view, the sub-sheet 26 is preferably attached to the service hole cover 22 in a watertight manner by welding or adhesion.

  Moreover, in the above, the example applied to the door structure (internal structure of the vehicle door) is given as the vehicle body structure of the present invention, and the service hole cover 22 is an example of the first plate member in the present invention. . However, the body part to which the present invention is applicable is not limited to such a door structure. That is, in a structure in which an insertion member such as a wire harness is inserted into an insertion hole such as a slit formed in the first plate-like member, the movement range of the insertion member is appropriately limited, and the position is maintained stably. It is preferable to do. The present invention can be preferably applied to such a part. However, in the door structure as described above, for example, it is assumed that the position of the wire harness changes with the opening / closing operation of the vehicle door. Moreover, various members are arranged in the vehicle door, and it is desired to prevent the wire harness from contacting and being caught in these members. Therefore, the door structure as described above is particularly preferable as an application target of the vehicle body structure of the present invention.
