JP 2004-10216 A Japanese Patent No. 2639512

  In the example disclosed above, the concavo-convex portions (engagement portions) that engage with each other exist on one side wall portion of the four side wall portions that surround the four sides. The other three side walls are substantially flush with the side walls and the legs at the corners at both ends of the side walls. Therefore, if any one of the three sides is used as a mounting surface when the roll-shaped material supported by the member is mounted on a pallet or the like, the peripheral direction of the flat plate portion which is the direction of the side wall portion and the leg It is placed on two surfaces, the direction protruding from the flat plate part, which is the direction of the part, and the stability of the placement is ensured.

  However, when the roll-shaped materials supported by the members are arranged adjacent to each other, the side wall portions that are adjacent to each other and are engaged with each other are only on one specific surface of the four surfaces. The side wall must be selected. The direction of adjacent placement is limited, and special consideration is required for adjacent placement.

  In this regard, in another example disclosed above, stack bosses and stack pockets are formed on each of the four side wall portions (side walls), and the side wall portions (side walls) can be freely selected when arranged adjacent to each other. It is secured.

  However, any of the four side walls (side walls) is a mounting surface. In this case, the mounting surface is limited to the protruding portion of the stack boss on the side wall (side wall). Since the arrangement area of the stack boss is limited within the range of the wall thickness of the side wall (side wall), the stack boss basically extends in the direction of the side wall. For this reason, the mounting surface only exists linearly in the direction of the side wall portion within the range of the wall thickness of the side wall portion. When the roll-shaped material supported by the member is placed, the support in the direction intersecting the direction of the placement surface, for example, the axial direction of the roll-shaped material may be unstable. Here, it is conceivable to secure a sufficient wall thickness. However, in this case, the physique and weight of the member are increased, and there is a possibility that the recovery and conveyance of the member may be hindered.

  The present invention has been proposed in view of the above-mentioned problems, and is used as a member that is attached to both ends of the roll-shaped material and sandwiches the roll-shaped material when the roll-shaped material is transported / stored. An object of the present invention is to provide a member for transporting and storing a roll-shaped material having a placement surface in which the stability of placement is ensured while ensuring the convenience of fitting.

The members for transporting and storing the roll-shaped material according to the present application are used in pairs, and each piece supports the respective ends of the bobbin portion of the roll-shaped material, thereby sandwiching the bobbin portion from both sides. It is used for transportation and storage. A rectangular flat plate portion, a support portion provided at the central portion of the flat plate portion for supporting the bobbin portion of the roll-shaped material, a rectangular side wall portion connected to the periphery of the flat plate portion, and each corner portion of the flat plate portion And a column portion provided upright from the flat plate portion. At one end of the side wall portion, the first convex portion disposed at the first position of the one end portion, straddling the side wall portion from the column portion, and the second position disposed at the second position adjacent to the first position. 1 recess. The other end of the side wall portion is fitted when the first convex portion is line-symmetrically folded with respect to the center line of the side wall portion parallel to the winding axis of the roll-shaped material supported by the support portion. A first fitting concave portion and a first fitting convex portion that fits when the first concave portion is line-symmetrically folded with respect to the center line are provided. Between the side wall of each first convex portion between the ends, the first recess, the first fitting recess, and the positional relationship of the first fitting projection is Ri same der, the first protrusion and the first fitting convex portion, Ru is formed in two directions of a direction intersecting the direction and the direction across the side wall portion to the support portion.

  The members for transporting and storing the roll material are used in pairs. By sandwiching the roll-shaped material from both ends of the winding shaft and bundling it with a bundling belt or the like, the roll-shaped material becomes a loadable state in which cargo handling such as transportation and storage is possible. The end portion of the roll-shaped material is supported by supporting the bobbin portion of the roll-shaped material with a support portion provided at the central portion of the rectangular flat plate portion.

  When roll-shaped materials in a state where cargo handling is possible are arranged side by side or stacked vertically, the side walls between the members for transporting and storing the roll-shaped materials arranged adjacent to each other come into contact with each other. At this time, the first convex portion, the first concave portion, the first fitting concave portion, and the first fitting convex portion formed on the side wall portion are each of the four side wall portions connected to the respective peripheral edges of the flat plate portion. The first protrusion of one side wall and the first fitting recess of the other side wall, and the first recess of one side wall and the first fitting protrusion of the other side wall. Each part fits.

A 1st convex part and a 1st fitting convex part are fitted in each of a 1st fitting recessed part and a 1st recessed part in two directions of the direction ranging from a side wall part to a support | pillar part, and the direction which cross | intersects this direction. Moreover, in the side wall part used as a mounting surface (bottom surface), a 1st convex part and a 1st fitting convex part can be handled in two directions, the direction over a side wall part and a support | pillar part, and the direction which cross | intersects this direction. Supports roll materials in

  Moreover, one of the side wall portions on the four sides serves as a placement surface (bottom surface) when placing the roll-shaped material in a loadable state. In the side wall part used as a mounting surface (bottom surface), the roll-shaped material which is in a cargo handling possible state is supported by the 1st convex part and the 1st fitting convex part.

  Further, the side wall portions are fitted to each other when they are folded symmetrically with respect to the center line at positions symmetrical with respect to the center line of the side wall portion parallel to the winding axis of the roll-shaped material in a loadable state. And at least a pair of second convex portions and second concave portions. Moreover, the positional relationship of a 2nd convex part and a 2nd recessed part is the same between each side wall part.

  In addition to the first convex portion, the first concave portion, the first fitting concave portion, and the first fitting convex portion, the side wall portion includes at least one pair of the second convex portion and the second concave portion.

  Thereby, in the adjacent arrangement, the first protrusion of one side wall and the first fitting recess of the other side wall, and the first recess of one side wall and the first fitting protrusion of the other side wall. In addition, the second convex portion of the one side wall portion and the second concave portion of the other side wall portion, and the second concave portion of the one side wall portion and the second convex portion of the other side wall portion are fitted.

  Moreover, in the side wall part used as the mounting surface (bottom surface) at the time of mounting, in addition to a 1st convex part and a 1st fitting convex part, the roll-shaped material in the state which can be handled by a 2nd convex part is supported.

  According to the member for transporting and storing the roll-shaped material according to the present application, when the roll-shaped material in a loadable state is placed adjacent to another roll-shaped material in any of the upper, lower, left, and right directions, One convex portion and the first fitting concave portion, and the first concave portion and the first fitting convex portion can be respectively fitted. When stacking up and down, or when connecting to the left and right, it is not necessary to select the orientation of the roll-shaped material that is adjacently placed and ready to be handled, and can be in a fitted state regardless of the orientation. . A degree of freedom in workability when adjacently arranged is ensured.

  Further, the first convex portion and the first fitting concave portion, and the first concave portion and the first fitting convex portion, which are fitted to each other, are all formed to extend from the side wall portion to the support column portion, and in the side wall portion. Compared with the case where it forms, it has a long shape. Therefore, the opposing sides in the fitted state of the first convex portion and the first fitting concave portion and the first concave portion and the first fitting convex portion that are fitted to each other can be made sufficiently long. When an external force is applied, it is the opposite side that is in the fitted state that receives the external force. When the opposite side has a sufficient length, it can withstand an external force and maintain the fitting state, and the fitting strength can be improved.

  Furthermore, the 1st convex part and 1st fitting convex part of a side wall part which correspond to the mounting surface (bottom surface) which mounts the roll-shaped material in the state which can be handled are formed ranging from a side wall part to a support | pillar part, Since it has a long shape compared to the case where it is formed, the area of the placement surface when placing the roll-shaped material in a loadable state can be increased. For this reason, the independence stability at the time of mounting improves.

In addition, a first convex portion and a first fitting convex portion are formed in two directions, a direction extending from the side wall portion to the support column portion and a direction intersecting with the direction, and fitting into the first fitting concave portion and the first concave portion, respectively. If so, it can withstand external force in at least two directions. The fitting state can be maintained regardless of the direction of the external force, and the fitting strength can be further improved. Moreover, when supporting a roll-shaped material in the mounting surface (bottom surface) of a roll-shaped material, since a 1st convex part and a 1st fitting convex part have a surface of 2 directions, self-supporting stability is further improved. be able to.

  Moreover, if each side wall part is provided with at least one pair of the second convex part and the second concave part, these parts are also used for fitting in the adjacent arrangement and also function as a mounting surface. The self-supporting stability in the fitted state and placement can be further strengthened.

  FIG. 1 is an exploded perspective view showing a configuration when a roll-shaped material R is supported by a member 1 for transportation and storage and is brought into a loadable state for transportation or storage. The roll-shaped material R is configured by winding a film-like long sheet around a bobbin portion BO. A pair of transport and storage members 1 and 1 are brought into contact with the bobbin BO with the roll material R sandwiched between both ends of the winding shaft of the roll material R, and the binding band BA is bridged. As a result, the roll-shaped material R is fixed together with the pair of materials 1 and 1 for transportation and storage and is ready for cargo handling. In this embodiment, the support part 13 which protrudes and is provided from the center part of the member 1 for conveyance storage mentioned later is inserted in the hollow hole of the bobbin part BO, and is attached. The material 1 for transportation and storage is supported so as to protect the roll-shaped material R in a state in which the material can be handled, and can be transported or stored.

  The perspective view of the member 1 for conveyance storage is shown to FIG. 2 is a perspective view seen from the side facing the roll-shaped material R, and FIG. 3 is a perspective view seen from the side opposite to the roll-shaped material R.

  First, the surface facing the roll-shaped material R will be described with reference to FIG. Opposite to the roll-shaped material R, a rectangular flat plate portion 11 is provided. On the four sides at the periphery of the flat plate portion 11, there are provided side wall portions 12 that are bent and connected to the rear of the flat plate portion 11 at substantially right angles.

  A cylindrical support portion 13 protrudes from the central portion of the flat plate portion 11. The support portion 13 has, for example, a truncated cone shape in which the diameter of the cross-section gradually decreases from the proximal end portion toward the distal end portion. Moreover, you may have a structure of providing an unevenness | corrugation or a rib in an outer surface. Thereby, when inserting the support part 13 in the hollow hole of the bobbin of the roll-shaped material R, both fitting strength can be ensured.

  At the corners corresponding to the four vertices of the flat plate portion 11, a support column portion 14 is erected so as to protrude in the same direction as the support portion 13. A disc-shaped fitting board 15 is formed at the tip of the column part 14. As shown in FIG. 11, the support column 14 and the fitting board 15 are provided with support columns for stacking the transport storage member 1 and transported storage storage when the transport storage member 1 is transported for collection. It becomes a contact part to the member 1.

  Next, the back surface on the opposite side to the roll-shaped material R will be described with reference to FIG. A plurality of ribs for ensuring the strength of the transporting and storing member 1 are formed on the back surface.

  A central annular rib 21 having a diameter larger than the diameter of the support portion 13 is formed at a position corresponding to the back surface of the support portion 13 in the central portion. In a state in which the transport and storage member 1 is stacked for collection and transportation (FIG. 11), the outer surface of the support portion 13 is stored in close contact with the inner surface of the central annular rib 21. In this case, the front end of the support portion 13 is retracted and stored to a position close to the step portion 21 a formed in the inner portion of the inner annular rib 21. In the state where the transport and storage member 1 is stacked, the tip of the support portion 13 and the stepped portion 21a are stacked with a predetermined gap. Even if there is variation between the individual members of the transporting and storing member 1 or deformation over time, the contact between the tip of the support portion 13 and the stepped portion 21a is the same as that of the fitting plate 15 provided at the tip of the column portion 14. The contact with the internal fitting chamber diagonal ribs 23a is not preceded. Thereby, at the time of lamination | stacking, the contact | abutting with the fitting board 15 and the corner fitting chamber diagonal rib 23a is performed reliably, and it can laminate | stack stably.

  At each corner, a corner fitting chamber 22 is formed in a substantially rectangular ring shape by two side walls 12 intersecting each other and a partition wall 22a connected thereto. When stacking the transport and storage member 1, the fitting board 15 is fitted into the corner fitting chamber 22. Diagonal ribs 23 that connect the central annular rib 21 and the partition wall 22a are formed on a diagonal line connecting the corner fitting chambers 22 positioned diagonally. Furthermore, corner fitting chamber diagonal ribs 23 a are formed on the diagonal extending from the diagonal ribs 23 and along the diagonal in the corner fitting chamber 22. Here, the corner fitting chamber diagonal ribs 23 a are formed at positions deeper than the diagonal ribs 23 by the thickness of the fitting board 15. When the transporting and storing member 1 is stacked, the front end portion of the fitting board 15 and the corner fitting chamber diagonal ribs 23a come into contact with each other.

  Further, each of the two side wall portions 12 facing each other is formed with a side wall connecting rib 24 parallel to the length direction of the side wall portion 12 on the other side. One is formed on each side of the central annular rib 21. In addition, partition wall connecting ribs 25 that connect adjacent partition walls 22 a are formed in parallel with the length direction of the side wall portion 12. Further, a side wall / center ring connecting rib 26 that connects the side wall portion 12 and the center ring rib 21 is formed. Furthermore, the auxiliary | assistant rib 27 which connects the adjacent side wall connection rib 24 and connects this to the side wall part 12 is formed.

  Next, the side structure will be described with reference to FIGS. FIG. 4 is a plan view of the side wall portion 12. Here, the side wall portion 12 has the same shape on all four sides.

  The column portions 14 are connected to both end portions of the side wall portion 12. In each end portion, the region extending from the side wall portion 12 to the support column portion 14 is bisected by an L-shaped surface end convex portion 31 and a surface end concave portion 31a that are bent in a bowl shape. The surface end convex portion 31 at one end portion is relative to the surface end concave portion 31a at the other end portion and the center line XX of the side wall portion 12 parallel to the winding axis of the roll-shaped material supported by the support portion 13. Are arranged in a line-symmetrical positional relationship.

  Further, at the center portion of the side wall portion 12, a rectangular surface center convex portion 32 and a surface center concave portion 32 a are formed in pairs by extending the thickness direction of the side wall portion 12 and extending in the length direction of the side wall portion 12. ing. And the shape of this pair is formed side by side on both sides of the center line XX. The arrangement positions in the thickness direction of the central convex part 32 and the central concave part 32a are opposite on the left side and the right side across the center line XX. That is, the central protrusion 32 on one side and the central recess 32a on the other side are arranged in a line-symmetrical positional relationship with respect to the center line XX.

  Here, the top end portion of the surface end convex portion 31 and the central surface convex portion 32 are partitioned by a plane parallel to the side wall portion 12. The height from the base end portion to the top portion of the surface end convex portion 31 and the surface central convex portion 32 is the same. Therefore, when the roll-shaped material R in a state capable of cargo handling is placed on a pallet or the like, the surfaces supporting the roll-shaped material R as the placement surface (bottom surface) are the top and two surfaces of the two surface end convex portions 31. There are a total of four apexes of the central convex portion 32. In addition to the direction along the length direction of the side wall portion 12 by the surface center convex portion 32 and the direction along the length direction of the side wall portion 12 of the surface end convex portion 31, the column portion 14 of the surface end convex portion 31. It is mounted with a top portion serving as a mounting surface (bottom surface) in a direction along the standing direction. It has a mounting surface (bottom surface) in two directions, and can be mounted in a state excellent in self-supporting stability.

  Further, the positional relationship among the surface end convex portion 31, the surface end concave portion 31 a, the central surface convex portion 32, and the central surface concave portion 32 a is the same in the four side wall portions 12. For this reason, when the roll-shaped material R in a state capable of cargo handling is arranged side by side horizontally or vertically, there is no restriction on the arrangement direction of each roll-shaped material R.

  FIG. 5 shows how the convex portions and the concave portions in the side wall portion 12 are adjacently disposed. When the two side wall portions 12 are opposed to each other, the one surface end convex portion 31 and the other surface end concave portion 31a, and the one surface central convex portion 32 and the other surface central concave portion 32a are in contact with each other. It is in a positional relationship that matches.

  Therefore, as shown in FIG. 6, when the roll-shaped material R in a loadable state is disposed adjacent to each other, the opposing side wall portions 12 are each of the surface end convex portions 31, the surface end concave portions 31 a, and the central surface convex portions 32. And the central recess 32a come into contact with each other and are fitted to each other, and the roll-shaped material R in a state capable of cargo handling is disposed adjacently.

  In this case, in the side wall part 12, between the surface end convex part 31 or the surface end recessed part 31a and the surface center convex part 32 and the surface center recessed part 32a, and two sets of the surface center convex part 32 and the surface center recessed part 32a. A band extending portion 33 is formed therebetween. The band transfer part 33 is a place where the binding band BA is bridged when the both sides of the roll-shaped material R are sandwiched and bound by the pair of members 1 for transport and storage. It is formed with a width that allows the binding band BA to be accommodated so that the binding band BA that is bridged when adjacently arranged does not have an insufficient fit. Further, the gap 33a corresponding to the thickness of the binding band BA is formed.

  The fitting is performed in two directions: a direction along the length direction of the side wall portion 12 and a direction along the standing direction of the support column portion 14, that is, a direction along the thickness direction intersecting the length direction of the side wall portion 12. Further, the convex portion and the concave portion are configured to face each other. The side wall portion is formed by fitting the surface center convex portion 32 and the surface center concave portion 32a and fitting the portion along the length direction of the side wall portion 12 among the surface end convex portion 31 and the surface end concave portion 31a. 12 are fitted with opposing surfaces in a direction along the length direction. By this opposing surface, the fitting strength in the thickness direction of the side wall portion 12 is ensured. Moreover, it is fitted with an opposing surface in the direction along the support | pillar part 14 among the fitting of the surface end convex part 31 and the surface end recessed part 31a. The opposing surface ensures fitting strength in the length direction of the side wall portion 12. Furthermore, by ensuring the fitting strength in these two directions, the fitting strength can also be ensured in the twisting direction.

  As shown in FIG. 10, in the case of adjacent arrangements such as stacking in the vertical direction and connection arrangement in the horizontal direction of the roll-shaped material R in a state capable of handling, any of the vertical direction, the horizontal direction, and the twist direction Since the fitting state is maintained even with respect to the external force in the direction, it is possible to effectively prevent misalignment or collapse of the load even when transported and stored in the vertical and horizontal directions.

  In FIG. 7, the perspective view seen from the side which opposes the roll-shaped material R about the member 1A for conveyance storage is shown. FIG. 8 is a plan view of the transport and storage member 1A as viewed from the side wall. The plan view has the same shape on four sides.

  1 A of conveyance storage members are provided with the surface end convex part 41 and the surface end recessed part 41a instead of the surface end convex part 31 and the surface end recessed part 31a in the member 1 for conveyance storage. Since the other structure is the same as that of the case of the member 1 for conveyance storage, description here is abbreviate | omitted.

  In each end portion of the side wall portion 12, the region extending from the side wall portion 12 to the support column portion 14 is a square surface end convex portion 41 and a surface end concave portion 41 a which is a concave portion into which the surface end convex portion 41 is fitted. Divided into two. The surface end convex portion 41 at one end portion is disposed at a position symmetrical with respect to the surface end concave portion 41 a at the other end portion and the center line XX of the side wall portion 12.

  The surface end concave portion 41 a is located adjacent to the surface end convex portion 41. At one end, a surface end convex portion 41 is provided at the outer end portion, and a surface end concave portion 41a is adjacent to the inside. At the other end, a surface end concave portion 41a is provided at the outer end portion, and the surface end convex portion 41 is adjacent to the inside thereof. The surface end concave portion 41 a disposed at the outer end portion also serves as a side wall of the surface end convex portion 41 disposed at one outer end portion of the adjacent side wall portion 12.

  The top end of the surface end convex portion 41 is partitioned by a plane parallel to the side wall portion 12, and the height from the base end portion to the top portion is the same as that of the central surface convex portion 32. Therefore, when the roll-shaped material R in a state where the material can be handled by the carrying and storing member 1A is placed on a pallet or the like, the surface supporting the roll-shaped material R as the placement surface (bottom surface) is the two surface end convex portions 41. , And two central projections 32 in total. In addition to the direction along the length direction of the side wall portion 12 by the center convex portion 32, the surface end convex portion 41 also has a top portion that becomes a mounting surface (bottom surface) in the direction along the support column portion 14. Placed. It has a mounting surface (bottom surface) in two directions, and can be mounted in a state excellent in self-supporting stability as in the case of the transporting and storing member 1.

  As in the case of the transport and storage member 1, also in the transport and storage member 1A, the positional relationship between the surface end convex portion 41, the surface end concave portion 41a, the surface central convex portion 32, and the surface central concave portion 32a is four sides. The side wall portions 12 are formed identically. For this reason, when the roll-shaped material R in a state capable of cargo handling is disposed adjacent to the left or right or up and down, there is no restriction on the arrangement direction of each roll-shaped material R.

  FIG. 9 shows a state of fitting between the convex portions and the concave portions in the side wall portion 12 when adjacently arranged. When the two side wall portions 12 are opposed to each other, the one surface end convex portion 41 and the other surface end concave portion 41a, and the one surface central convex portion 32 and the other surface central concave portion 32a are fitted to each other. It is a positional relationship.

Therefore, as in the case of the transport and storage member 1 (FIG. 6), when the transport and storage member 1A is disposed adjacent to each other, the opposing side wall portions 12 are respectively connected to the surface end convex portions 41 and the surface end concave portions 41a, The in-plane convex part 32 and the in-plane concave part 32a can be fitted and adjacent to each other.

  As in the case of the transport and storage member 1, the fitting intersects the direction along the length direction of the side wall portion 12 and the direction along the standing direction of the support column portion 14, that is, the length direction of the side wall portion 12. The convex part and the concave part are configured so as to face each other in two directions along the thickness direction. Thereby, fitting strength is secured in these two directions. Further, the fitting strength can be ensured in the twisting direction by the fitting in these two directions.

  In the case of adjacent arrangements such as stacking in the vertical direction and connection arrangement in the horizontal direction as shown in FIG. 10, the fitting state is applied to any external force in the vertical direction, the horizontal direction, and the twisting direction. Therefore, even when transported and stored in the vertical and horizontal directions, it is possible to effectively prevent misalignment and load collapse.

  Here, the surface end convex portions 31 and 41 at one end of the side wall portion 12 are an example of either the first convex portion or the first fitting convex portion, and are formed at the other end portion of the side wall portion 12. The certain surface end convex portions 31 and 41 are an example of the other one of the first convex portion and the first fitting convex portion. Similarly, the surface end recesses 31 a and 41 a at one end of the side wall 12 are an example of either the first recess or the first fitting recess, and the surface end at the other end of the side wall 12. The recesses 31a and 41a are one example of either the first recess or the first fitting recess. Further, the center convex portion 32 is an example of a second convex portion, and the central recess portion 32a is an example of a second concave portion.

  As described above in detail, according to the embodiment of the present invention, when the roll-shaped material R is sandwiched between the up-and-down and left-right directions by the carrying and storage member 1 or 1A that enables loading and unloading. Also, between the side wall portion 12 of the transporting and storing member 1 or 1A, the surface end convex portion 31 or 41 and the surface end concave portion 31a or 41a, and the surface central convex portion 32 and the surface central concave portion 32a are fitted to each other. Adjacent placement is possible without any backlash. In this case, it is not necessary to select the arrangement direction of the roll-shaped material R that is adjacently disposed and ready to be handled, and the fitting state can be formed regardless of the orientation.

  Further, the surface end convex portion 31 and the surface end concave portion 31 a or the surface end convex portion 41 and the surface end concave portion 41 a which are fitted to each other are formed in a region extending from the side wall portion 12 to the column portion 14. In addition to the fitting along the length direction of the side wall portion 12 by the central convex portion 32 and the central concave portion 32 a formed in the side wall portion 12, the direction along the support column portion 14, that is, the thickness of the side wall portion 12. It is also fitted in the direction. Since the fitting is performed in two different directions, the fitting state can be maintained regardless of the direction of the external force, and the fitting strength can be improved. In addition, when the roll-shaped material is placed on the mounting surface (bottom surface), the roll-shaped material R is supported by having the mounting surface (bottom surface) in two directions. it can.

  Needless to say, the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention.

  For example, in the embodiment, the support portion 13 is formed to protrude from the flat plate portion 11 and is inserted into the hollow hole of the bobbin portion BO of the roll-shaped material R, but the present application is not limited to this. If the bobbin part BO is a structure which protrudes from the end surface of the roll-shaped material R, it can also be set as a support part by forming an opening in the flat plate part 11.

  Moreover, as a structure which bisects the area | region ranging from the side wall part 12 to the support | pillar part 14, the surface end convex part 31 and the surface end recessed part 31a which have L shape, or the surface end convex part 41 and the surface end recessed part 41a which have a square shape However, the present application is not limited to this. Other configurations are possible as long as the region extending from the side wall portion 12 to the column portion 14 is divided into two. For example, it can be bisected by a triangular shape. Also, a U-shape or the like is possible. In particular, as long as the shape has walls facing each other in the length direction of the side wall portion 12 and the thickness direction crossing this direction, the strength can be maintained to maintain the fitted state regardless of the direction of the external force. .

Moreover, although the structure provided with the two sets of the surface center convex part 32 and the surface center recessed part 32a was illustrated in the side wall part 12, this application is not limited to this. If it is set as 3 or more sets, the improvement of fitting strength and the self-supporting stability at the time of mounting can be improved further.
