Description

  The present invention relates to a vehicle electrical component housing case for housing electric wires or electronic control components in a vehicle.

  A protector may be used for a wire harness in a vehicle or the like in order to restrict and protect the electric wire included in the wire harness according to the arrangement route.

  Examples of the protector as described above are disclosed in Patent Documents 1 and 2.

  Patent document 1 is disclosing the protector which provided the cover body in the protector main body of the long U-shaped groove body.

  Patent document 2 is disclosing the technique which folds the paperboard sheet | seat material formed by mixing a pulp fiber material and a waterproof resin solution, and accommodates a wire harness.

Japanese Patent Laid-Open No. 08-154324 Japanese Patent Laid-Open No. 10-191529

  However, in the protector disclosed in Patent Document 1, it is necessary to manufacture a protector having a shape corresponding to the arrangement path of the wire harness using an injection mold apparatus. For this reason, a large and complicated injection mold apparatus is required.

  In addition, the protector disclosed in Patent Document 2 has a problem that the strength is low because the pulp fiber material uses a sheet material sheet mixed with a waterproof resin solution for waterproofing.

  In view of this, it has been proposed to bend a hollow plate material in which a hollow structure is formed between a plurality of plate-shaped portions to form a shape that can accommodate a wire harness.

  However, when such a hollow plate material starts burning, air may be supplied to the burning portion through the space in the hollow plate material.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to further reduce the speed at which the flame spreads when a housing case for a vehicle electrical component is formed by bending a hollow plate material.

  In order to solve the above-described problem, the vehicle electrical component storage case according to the first aspect is disposed between a plurality of plate-like portions and the plurality of plate-like portions, and is hollow between the plurality of plate-like portions. A hollow plate material including an intervening portion that forms a space is bent and formed into a shape that can accommodate a vehicle electrical component, and the hollow plate material is partially deformed so as to partially block the hollow space. Provided with a protruding portion.

  A 2nd aspect is a storage case for vehicle electrical components which concerns on a 1st aspect, Comprising: As for the said protrusion part, at least 1 of these plate-shaped parts protrudes toward the said hollow space. It is formed by being partially processed.

  A 3rd aspect is a storage case for vehicle electrical components which concerns on a 1st or 2nd aspect, Comprising: The said interposition part parallels several elongate said hollow space between these several plate-shaped parts. The protrusion is formed at a position that blocks the hollow space in the extending direction.

  A 4th aspect is a storage case for vehicle electrical components which concerns on a 3rd aspect, Comprising: The said protrusion part was formed corresponding to two adjacent things among these hollow spaces. And the second protrusion, and the first protrusion and the second protrusion are provided at positions shifted in the extending direction of the hollow space.

  A 5th aspect is a storage case for vehicle electrical components which concerns on any one 1st-4th aspect, Comprising: The said hollow plate material is a pair of side wall part standingly arranged by the both sides of the bottom part and the said bottom part It is provided with the accommodating main-body part formed by bending so that it may become a shape containing these.

  A sixth aspect is a vehicle electrical component housing case according to the third or fourth aspect, wherein the hollow plate member includes a bottom part and a pair of side wall parts erected on both side parts of the bottom part. And the hollow space extends along the extending direction of the housing main body.

  In the electric wire module according to the seventh aspect, the vehicle electrical component storage case according to any one of the first to sixth aspects and at least a part of the extending direction are stored in the vehicle electrical component storage case. With electric wires.

  According to the 1st-7th aspect, since the said hollow plate material is provided with the projection part deform | transformed partially so that the said hollow space may be partially interrupted, it becomes difficult to flow air in a hollow plate material. For this reason, even if a hollow board material starts combustion, it becomes difficult to supply air through the space in a hollow board material with respect to the combustion part. Thereby, the speed which spreads can be reduced more.

  According to the second aspect, since it is sufficient to process at least one of the plurality of plate-like portions, the protrusion can be easily formed.

  When the hollow space in the hollow plate material is elongated, air easily flows in the extending direction. Therefore, if the protrusion is formed at a position where the hollow space is blocked in the extending direction, it becomes difficult for air to flow in the extending direction of the hollow space, and the speed at which the flame spreads can be effectively reduced. .

  According to a fourth aspect, the plurality of protrusions include a first protrusion and a second protrusion formed corresponding to two adjacent ones of the plurality of hollow spaces, and the first protrusion Since the portion and the second projecting portion are provided at positions shifted in the extending direction of the hollow space, the hollow plate material is difficult to bend at the portion where the projecting portion is formed.

  According to the 5th aspect, it can be set as the structure suitable for accommodating the electric wire as a vehicle electrical component in the space enclosed by a bottom part and a pair of side wall part.

  According to the sixth aspect, since the hollow space extends along the extending direction of the housing main body portion, the extending direction of the interposition part that partitions the hollow space is in the extending direction of the housing main body portion. Will extend along. For this reason, it is hard to bend an accommodating main-body part. Moreover, the speed which spreads in the extension direction of a storage main-body part can be reduced more.

  According to the seventh aspect, it is possible to regulate the path while accommodating and protecting at least a part of the extending direction of the electric wire in the vehicle electrical component housing case.

  Hereinafter, the electric wire module according to the embodiment will be described. In the present embodiment, an example in which the vehicle electrical component housing case is used as a protector that houses at least a part of the extending direction of at least one electric wire will be described.

<Overall structure of electric wire module>
The overall structure of the electric wire module 10 will be described. FIG. 1 is a schematic perspective view showing the electric wire module 10, and FIG. 2 is a partially enlarged view of FIG.

  The electric wire module 10 includes at least one electric wire 14 and a protector 20 as a vehicle electrical component storage case.

  The electric wire 14 is configured such that an insulation coating or the like is extruded around the conductor. Here, the electric wire module 10 includes an electric wire bundle 12 (wire harness) in which a plurality of electric wires 14 are bundled. The wire bundle 12 may be branched at an intermediate portion in the extending direction of the protector 20 or outside. Here, a part of the extending direction of the wire bundle 12 is accommodated in the protector 20.

  As will be described below, the protector 20 is formed by bending the hollow plate member 50 into a shape that can accommodate the wire bundle 12 that is a kind of vehicle electrical component. The hollow plate member 50 includes a plurality of plate-like portions 52 and intervening portions 54 disposed between the plurality of plate-like portions 52, and a hollow space is formed between the plurality of plate-like portions 52 by the interposition portions 54. It is set as the formed structure.

  Here, an example of the hollow plate member 50 will be described with reference to FIG.

  The hollow plate member 50 includes a plurality (two in this case) of plate-like portions 52 and an interposition portion 54 disposed between the plurality of plate-like portions 52. Here, the hollow plate member 50 includes a plurality of interposition portions 54 interposed in parallel between the plurality of plate-like portions 52.

  The plate-like portion 52 is formed in a flat plate shape. A plurality of plate-like portions 52 are connected via an intervening portion 54 with a space therebetween.

  The plurality of interposition parts 54 are arranged in parallel between the two plate-like parts 52 with a space therebetween. Each interposed portion 54 is formed in an elongated plate shape, and is disposed in a vertical posture with respect to the two plate-like portions 52. One side portion of each interposition portion 54 is connected to one plate-like portion 52, and the other side portion is connected to another one plate-like portion 52. Thereby, the two plate-like portions 52 and the plurality of interposition portions 54 are integrally connected so as to exhibit a ladder-like cross section in a plane orthogonal to the extending direction of the interposition portions 54.

  The plurality of interposition parts 54 form a plurality of elongated hollow spaces in parallel between the plurality of plate-like parts 52. Each hollow space is surrounded by two intervening portions 54 and two adjacent intervening portions 54. Therefore, the cross-sectional shape orthogonal to the extending direction has a square shape.

  In addition, the material which forms the several plate-shaped part 52 and the interposition part 54 is not specifically limited. The plurality of plate-like portions 52 and the intervening portions 54 may be formed of paper, may be formed of resin, or may be configured by a combination thereof. When at least one of the plurality of plate-like portions 52 and the intervening portion 54 is formed of paper, it is preferable to perform a water repellent treatment or the like on the surface.

  When the hollow plate material 50 is molded from a resin, for example, the hollow plate material 50 can be continuously produced by an extrusion molding apparatus that extrudes resin from an extrusion hole corresponding to the ladder-shaped cross section. Thus, the hollow plate member 50 can be easily manufactured at low cost. The interposition part 54 may be connected to the plate-like part 52 by an adhesive or welding.

  According to such a hollow plate member 50, the plurality of plate-like portions 52 are connected by the interposition portions 54 at intervals, and thus are difficult to bend. Further, since the interposition portion 54 is interposed between the plate-like portions 52, the hollow plate material 50 is also reinforced by the interposition portion 54 so that it is difficult to bend and dent. In particular, in this example, the hollow plate member 50 can be made difficult to bend in the extending direction of the interposition part 54.

  Therefore, by manufacturing the protector 20 using the hollow plate member 50, the electric wire 14 can be sufficiently protected and the path can be sufficiently restricted. Further, since a hollow structure is formed between the plurality of plate-like portions 52 of the hollow plate member 50, the weight can be reduced and the material cost can be reduced accordingly.

  Note that an electromagnetic shield member such as a metal foil (aluminum foil) may be provided on at least a part of the hollow plate member 50 described above.

  Moreover, when each hollow plate material includes three or more plate-like portions, it is preferable that an intervening portion is provided between each. Thereby, the intensity | strength of a hollow plate material can be improved more.

  The protector 20 is formed by bending the hollow plate member 50.

  Here, the protector 20 includes a housing main body portion 21 including a bottom portion 22 and a pair of side wall portions 24, a first lid portion 26, and a second lid portion 28.

  The bottom 22 is formed in an elongated plate-like portion. The pair of side wall portions 24 are formed in an elongated plate shape, and are erected so as to protrude from both side portions of the bottom portion 22 to one main surface side of the bottom portion 22. And the said wire bundle 12 is accommodated in the space in the accommodating main-body part 21 comprised by the bottom part 22 and a pair of side wall part 24. FIG.

  The first lid portion 26 and the second lid portion 28 are formed in an elongated plate shape. The first lid part 26 is formed so as to extend from one side wall part 24 toward the other side wall part 24. The second lid portion 28 is formed so as to extend from the other side wall portion 24 toward the one side wall portion 24.

  That is, the hollow plate material 50 before forming the protector 20 is formed in a square shape, and the hollow plate material 50 is bent at a plurality of linear folds arranged in parallel at intervals, whereby the bottom portion is formed. 22, a pair of side wall portions, a first lid portion 26, and a second lid portion 28.

  Here, in each fold of the hollow plate member 50, the plate-like portion 52 that is positioned on the outer peripheral side is cut along the fold. Thereby, the hollow plate material 50 is bent beautifully along the fold. However, it is not essential that the plate-like portion on the outer peripheral side is cut at the 50th folding plate.

  And the 1st cover part is in the state which accommodated the extension direction intermediate part of the wire bundle 12 in the accommodation main-body part 21, and pulled out the both ends of the wire bundle 12 through the both-ends opening of the accommodation main-body part 21 outward. 26 is folded so as to be disposed over the entire end portion of the pair of side wall portions 24. Subsequently, the second lid portion 28 is overlaid on the first lid portion 26 so as to cover the entire outside of the first lid portion 26. In this state, the overlapping state of the first lid portion 26 and the second lid portion 28 is maintained. This superposition state is maintained, for example, by forming one tab-like piece of the second lid portion 28 and the first lid portion 26 and forming a slit in the other, and inserting the tab-like piece into the slit. The second lid portion 28 and the first lid portion 26 are overlapped and bonded by ultrasonic welding, heat welding, adhesive, or the like, and an adhesive tape is wound around the outer periphery of the protector 20. Can do.

  In the completed form of the protector 20, the extending direction of the elongated hollow space of the hollow plate member 50 coincides with the extending direction of the protector 20. Since the hollow plate member 50 is difficult to bend in a direction orthogonal to the extending direction of the hollow space (that is, the extending direction of the interposition part 54), the extending direction of the elongated hollow space of the hollow plate member 50 is set as described above. By doing so, the protector 20 becomes difficult to bend. Thereby, path | route control of the wire bundle 12 can be performed more reliably. But the extension direction of the elongate hollow space of a hollow board | plate material may cross | intersect (the orthogonal direction is included) with respect to the extension direction of a protector.

  The protector 20 has a square tube shape in the completed form, but may have a circular tube shape or the like. In addition, here, the protector 20 extends linearly, but may be bent in the middle thereof. As a configuration for bending the protector, for example, a configuration in which an accordion structure is formed in the intermediate portion in the extending direction, or a configuration in which the intermediate portion in the extending direction of the protector is cut off except for a part around the outer periphery, and the like. Can be adopted. Further, an opening for branching a part of the inner wire bundle and guiding it outward may be formed in the intermediate portion of the protector 20 in the extending direction.

  One or both of the first lid portion 26 and the second lid portion 28 of the protector 20 may be omitted.

  The protector 20 configured as described above is formed by partially deforming the hollow plate member 50 to form a protrusion 30 for partially blocking the hollow space.

<Protrusions>
4 is a schematic partial sectional view taken along line IV-IV in FIG. 2, and FIG. 5 is a schematic partial sectional view taken along line VV in FIG. 4 and 5 also show a processing tool 38 for forming the protrusion 30.

  As shown in FIGS. 1 to 4, the protector 20 has a protrusion 30. Here, a plurality of protrusions 30 are formed on the protector 20. FIG. 1 shows a state in which at least one protrusion 30 is formed corresponding to each of the plurality of hollow spaces of the second lid 28. Further, the protrusions 30 are similarly formed on each of the bottom portion 22 and the pair of side wall portions 24, but FIG. 1 shows a state in which one protrusion 30 is formed on one side wall portion 24, and the like. Is omitted.

  When attention is paid to the second lid 28, the first protrusions 30a and the second protrusions 30b are alternately formed in the parallel direction with respect to the plurality of hollow spaces formed in parallel (FIG. 1). . That is, the 1st protrusion part 30a and the 2nd protrusion part 30b are formed corresponding to two adjacent things among several hollow spaces. In addition, when it is necessary to distinguish the formation position regarding the projection part 30, it attaches | subjects the referential mark 30a, 30b, and attaches | subjects the referential mark 30 when it is not necessary to distinguish the formation position.

  The first protrusion 30a and the second protrusion 30b are provided at positions shifted in the extending direction of the hollow space. Therefore, even when the first protrusion 30a or the second protrusion 30b is formed in each of the hollow spaces formed in parallel, the first protrusion 30a and the second protrusion 30b are the second lid portion. The positional relationship is not arranged in a line in the width direction of 28. Between each of the plurality of first protrusions 30a, there is a portion where none of the protrusions 30a, 30b is formed. Similarly, any of the protrusions 30a, 30b, between each of the plurality of second protrusions 30b. A portion where 30b is not formed is interposed.

  Moreover, the protrusion part 30 is formed in the position which interrupts | blocks the elongate hollow space in the extension direction. Here, at least one (here, two) protrusions 30 are formed in the intermediate portion in the extending direction of the hollow space. Therefore, it is difficult for air to flow along the extending direction of the elongated hollow space.

  But the projection part may be formed in the edge part of elongate hollow space.

  The protruding portion 30 is formed by partially deforming at least one of the plurality of plate-like portions 52 so as to protrude into the hollow space. Here, among the plurality of plate-like portions 52, the one located on the outer surface side of the protector 20 is partially deformed so as to partially protrude toward the hollow space.

  More specifically, the protrusion 30 is formed by bending a part of the belt-like portion of the plate-like portion 52 along the elongated hollow space toward the hollow space. Both ends of the short strip portion forming the protrusion 30 in the plate portion 52 are connected to the other portions of the plate portion 52, and both side portions of the short strip portion are separated from the other portions. Then, the central portion in the extending direction of the belt-like portion is bent so as to be closest to the other plate-like portion 52. Thereby, the projection part 30 has interrupted the elongate hollow space in the middle in the extension direction. Here, the protrusion 30 is bent in a U shape so as to be curved, but may be bent in an V shape at an angle.

  When the hollow space is viewed along the extending direction, it is preferable that the protrusion 30 protrudes over the entire hollow space and completely blocks the hollow space, but this is not essential. When the hollow space is viewed along the extending direction, a gap may be formed at the tip and both sides of the protrusion 30. Even in this case, the flow of air through the hollow space can be suppressed.

  The protrusion 30 as described above can be formed by pressing and pressing a rod-shaped processing tool 38 against the hollow plate member 50.

  That is, the processing tool 38 is formed in a rectangular parallelepiped bar shape. When the tip of the processing tool 38 is viewed in the width direction (see FIG. 4), it has a shape that is rounded to draw a semicircular arc. Further, when the front end portion of the processing tool 38 is viewed from the front side orthogonal to the width direction (see FIG. 5), the processing tool 38 has a rectangular shape. The width dimension of the processing tool 38 is formed to be the same as or smaller than the dimension between the adjacent interposition portions 54.

  Then, in a state where the hollow plate material 50 is arranged on the processing table or the like, the processing tool 38 is arranged in a posture along the width direction of the hollow space. When pressed against the plate-like portion 52 on one side, the short belt-like portion forming the protrusion 30 in the plate-like portion 52 is pressed and protrudes into the hollow space. Here, it is assumed that both sides of the short strip portion are sheared by both side edges of the processing tool 38 during the press working, but both sides of the strip portion are deformed while being connected to other portions. Also good.

  When the plate-shaped portion 52 is pressed by the processing tool 38, if the processing tool 38 is heated, the plate-shaped portion 52 becomes soft or partially melted, so that the processing can be easily performed.

  The above processing is preferably performed before the hollow plate material 50 is bent into the shape that forms the protector 20, that is, in the form of a flat plate.

  In addition, although it was set as the structure which shields hollow space by deforming the plate-shaped part 52 here, it is good also as a structure which interrupts hollow space by deforming an interposition part. For example, you may make it interrupt the said hollow space by deform | transforming an interposed part in the edge part of the extension direction of a hollow space.

<Effects>
According to the electric wire module 10 and the protector 20 configured as described above, the hollow plate member 50 includes the protrusion 30 that is partially deformed so as to partially block the hollow space. The air flow at is suppressed by the protrusion 30. For this reason, even if the hollow plate member 50 starts to burn, it becomes difficult for air to be supplied to the burning portion through the space in the hollow plate member 50. Thereby, the speed which spreads can be reduced more.

  Of course, since the protrusion 30 is formed by partially deforming the hollow plate member 50, the hollow structure is maintained in other portions. For this reason, effects, such as weight reduction and material cost reduction by using the hollow plate material 50, can fully be exhibited.

  Moreover, since the projection part 30 is formed by processing the plate-shaped part 52 partially in the hollow plate material 50, the projection part 30 can be formed easily. In addition, it is preferable that the plate-like portion 52 to be processed is located on any outer surface of the hollow plate member 50.

  In addition, in the state assembled as the protector 20, the protrusion 30 may be recessed from the outside to the inside of the protector 20, or may be recessed from the inside to the outside.

  Further, in the hollow plate member 50 as described above, air easily flows in the extending direction of the elongated hollow space. Therefore, if the protrusion 30 is formed at a position where the hollow space is blocked in the extending direction, air hardly flows in the extending direction of the hollow space. Thereby, the speed which spreads can be reduced effectively.

  The plurality of protrusions 30 include a first protrusion 30a and a second protrusion 30b that are formed corresponding to two adjacent ones of the plurality of hollow spaces, and the first protrusion 30a and the second protrusion 30b. The protrusion 30b is provided at a position shifted in the extending direction of the hollow space. Although the hollow plate member 50 is inferior in strength at the portion where the first protrusion 30a or the second protrusion 30b is formed, the first protrusion 30a and the second protrusion 30b do not line up linearly. For this reason, it becomes difficult for the hollow plate member 50 to bend at the portion where the first protrusion 30a or the second protrusion 30b is formed.

  Further, since the hollow space of the hollow plate member 50 extends along the extending direction of the housing main body 21, the extending direction of the interposition part 54 that partitions the hollow space is along the extending direction of the housing main body 21. Will be extended. For this reason, it becomes difficult for the accommodation main-body part 21 to bend. Therefore, when the wire bundle 12 is accommodated by the protector 20, the route of the wire bundle 12 can be more reliably regulated. In this case, since the protrusion 30 is formed at a position that blocks the hollow space of the hollow plate member 50 in the extending direction, the speed at which the burning spreads in the extending direction of the housing main body 21 can be further reduced. .

<Modification>
Based on the above embodiment, various modifications will be described.

  6 is a schematic perspective view showing a protrusion 130 according to a modification, FIG. 7 is a schematic partial cross-sectional view taken along line VII-VII in FIG. 6, and FIG. 8 is a schematic partial cross-sectional view taken along line VIII-VIII in FIG. FIG.

  In this modification, the protrusion 130 is formed in a shape that protrudes into a truncated cone shape by cutting off the apex of the cone shape. That is, the protruding portion 130 is formed by projecting a part of the strip-shaped portion along the elongated hollow space in the plate-shaped portion 52 in a truncated cone shape toward the hollow space.

  The tip of the projection 130 is in contact with or near the inner surface of the other plate-like portion 52, and both sides of the projection 130 are located near the side surface of the interposition portion 54. For this reason, the hollow plate member 50 is blocked in the extending direction by the protrusion 130.

  The protrusion 130 as described above can be formed by pressing and pressing a rod-shaped processing tool 138 against the hollow plate member 50.

  That is, the processing tool 138 is formed in a round bar shape. The outer diameter of the processing tool 138 is formed to be smaller than the dimension between adjacent intervening portions 54.

  When the tip of the processing tool 138 is pressed against the plate-like portion 52 on one side of the hollow plate 50 in a state where the hollow plate 50 is disposed on the processing table or the like, the plate-like portion 52 is pressed, Of the plate-like portion 52 that is in contact with the tip end surface of the processing tool 138 is recessed in the hollow space, and the portion of the plate-like portion 52 that is in contact with the tip end surface of the processing tool 138 is pushed into the hollow plate 50. It is. Thereby, the truncated cone-shaped protrusion 130 is formed.

  Also by this modification, the same effect as the said embodiment can be acquired. Note that, when the press working is performed, a part of the protrusion 130 may be broken, but it is preferable that the protrusion 130 is not broken. This is to suppress the inflow of air from the broken portion.

  Note that the protrusion is not limited to the shape described in the embodiment and the modification, and may have any shape. For example, the protruding portion may have a V-shaped protruding shape. Moreover, the protrusion part may be formed ranging over several hollow space formed in parallel.

  Moreover, the example of a hollow plate material is not restricted to what was demonstrated by the said embodiment.

  For example, the hollow plate member 250 shown in FIG. 9 has a configuration in which an interposition portion 236 is provided between a plurality (here, two) of plate-like portions 232.

  The interposition part 236 is a member formed in a plate shape having an uneven shape. The interposition part 236 is joined to the inward surface of the plate-like part 232 in a state of being sandwiched between the plurality of plate-like parts 232. The plate-like portion 232 and the interposed portion 236 are joined with, for example, an adhesive or a pressure-sensitive adhesive. Thereby, a hollow structure corresponding to the uneven shape exhibited by the interposition portion 236 is formed between the plurality of plate-like portions 232.

  Here, the interposition part 236 is formed in a shape in which a peak part 236a and a valley part 236b are continuous in a wave shape. The extending direction of the peak part 236a and the extending direction of the valley part 236b are in a parallel positional relationship. Therefore, when the interposition part 236 is viewed in plan, the plurality of peak parts 236a and the plurality of valley parts 236b are alternately arranged. It is set as the structure formed in parallel. The top part of the peak part 236a and the bottom part of the valley part 236b may be curved, or may be bent at a predetermined angle. Of the peak portion 236a and the valley portion 236b, a portion disposed between the plate-like portions 232 becomes a partition portion that forms a plurality of spaces extending in parallel.

  And the interposition part 236 is inserted | pinched between the several plate-shaped parts 232, while the lower surface of the bottom part of the trough part 236b and the lower plate-shaped part 232 are joined, the upper surface of the top part of the peak part 236a, and upper side The plate-like portion 232 is joined.

  Similarly to the above-described embodiment or modification, protrusions 30 and 130 (only one protrusion 30 is shown in FIG. 9) can be formed on such a hollow plate member 250.

  FIG. 10 is a partially cutaway perspective view showing a hollow plate 350 according to another modification. The hollow plate 350 according to the example shown in FIG. 10 has a configuration in which an interposition portion 336 is provided between a plurality (here, two) of plate-like portions 332.

  That is, the interposition part 336 is a member formed in a plate shape having an uneven shape, and more specifically, a configuration in which a plurality of protrusions 337 are formed so as to be scattered in a plan view of the interposition part 336. Has been. Here, in a state in which the interposition portion 336 is viewed in plan, the plurality of protrusions 337 are formed so as to be arranged at regular intervals in the vertical and horizontal directions. The protrusion 337 is formed so as to protrude from the substrate portion 338 extending in a flat plate shape in the interposition portion 336 to the one main surface side, and has a shape in which the upper end portion of the cylinder is closed. Here, the protrusion 337 is formed in a shape that gradually narrows upward, ie, a frustum shape. The protrusion 337 may be formed in a truncated cone shape, may be formed in a truncated pyramid shape, or may be formed in a shape obtained by rounding the corners of the truncated pyramid.

  Then, the interposition part 336 is sandwiched between the plurality of plate-like parts 332, the lower surface of the substrate part 338 is joined to the lower plate-like part 332, and the top part of the protrusion 337 is joined to the upper plate-like part 332. ing.

  Also for such a hollow plate 350, the protrusions 30 and 130 (only one protrusion 130 is shown in FIG. 10) can be formed as in the above-described embodiment or modification. Also in such a hollow plate 350, by forming the protrusions 30 and 130, the flow of air in the hollow space is hindered, so that the speed at which the flame spreads can be further reduced.
