However, the number of arrangements of the first inclined surface 111 and the size of one first inclined surface 111 are not limited to those shown in the figure, and are appropriately set according to the size of the outer wall surface member 11.

The outer wall surface member 11 has a rectangular first opening 112 penetrating the outer wall surface member 11 on the lowest end 111a side of each first inclined surface 111. The weight of the outer wall surface member 11 is reduced by the first opening 112. The first opening 112 has the same width as the width of the first inclined surface 111 in the Z1-Z2 direction, is adjacent to the lowest end 111a of the first inclined surface 111 arranged on the Y1 direction side, and is in the Y2 direction. It is arranged so as to be adjacent to the highest end 111b of the first inclined surface 111 arranged on the side. Therefore, the first opening 112 and the first inclined surface 111 are alternately arranged along the Y1 direction. The first opening 112 arranged at the end portion 11d on the most Y2 direction side of the outer wall surface member 11 is provided so as to open to the Y2 direction side of the outer wall surface member 11.

In the outer wall surface member 11, both side edges 11c and 11c extending along the Y1-Y2 direction are provided with a plurality of rectangular displacement prevention plate portions 113 protruding toward the slide member 12 side, respectively. The misalignment prevention plate portions 113 and 113 of the side edges 11c and 11c are arranged so as to be staggered along the Y1-Y2 direction. The distance between the adjacent deviation prevention plate portions 113 and 113 on one side edge 11c is set to correspond to the width of the deviation prevention plate portion 113 arranged on the other side edge 11c along the Y1-Y2 direction. .. Therefore, when the two outer wall surface members 11 and 11 are aligned in the Y1-Y2 direction and the inner side surfaces 11a and 11a are overlapped with each other facing each other (when the outer wall surface members 11 and 11 are in a reduced state), the figure is shown. As shown in 4, the displacement prevention plate portions 113, 113 of the outer wall surface members 11 and 11 are alternately combined so as to prevent mutual positional deviation of the outer wall surface members 11 and 11 along the Y1-Y2 direction. It has become.

In the slide member 12, a plurality of second inclined surfaces 121 are provided on both outer surface surfaces 12a and 12a facing the outer wall surface members 11 and 11. The second inclined surface 121 has substantially the same size as the first inclined surface 111 of the outer wall surface member 11, and has a shape in which the inclined direction is opposite to the first inclined surface 111. The second inclined surface 121 is arranged at the same position on both outer surfaces 12a and 12a. Therefore, the second inclined surfaces 121 and 121 of both outer surfaces 12a and 12a are inclined so as to gradually widen along the Y2 direction.

The second inclined surface 121 is arranged on both outer surfaces 12a and 12a of the slide member 12 in the same number as the first inclined surface 111 so as to correspond to the first inclined surface 111 of the outer wall surface member 11. Each second inclined surface 121 has the same structure. The second inclined surface 121 is arranged on the slide member 12 so as to be offset toward the Y1 direction as a whole.

In the present embodiment, the highest end portion 121b of the second inclined surface 121 is a flat surface substantially parallel to the outer surface 12a, similarly to the highest end portion 111b of the first inclined surface 111.

Similar to the outer wall surface member 11, the slide member 12 also has a rectangular second opening 122 penetrating the slide member 12 on the lowest end 121a side of each second inclined surface 121. The weight of the slide member 12 is reduced by the second opening 122. The second opening 122 has the same width as the width of the second inclined surface 121 in the Z1-Z2 direction, is adjacent to the lowest end portion 121a of the second inclined surface 121 arranged on the Y2 direction side, and is in the Y1 direction. It is arranged so as to be adjacent to the highest end portion 121b of the second inclined surface 121 arranged on the side. Therefore, the second inclined surface 121 and the second opening 122 are alternately arranged along the Y1 direction.

The slide member 12 has a rectangular push surface portion 123 at the end portion 12b on the Y2 direction side. The height of the push surface portion 123 is equal to the height of the main body portion of the slide member 12. Further, the width of the push surface portion 123 along the X1-X2 direction is larger than the width (thickness) of the main body portion of the slide member 12. The end portion of the slide member 12 on the Y2 direction side has a T-shape in a plan view due to the provision of the push surface portion 123, and is formed in a wide shape.

The push surface portion 123 has a plurality of convex portions 124 on both end faces in the X1-X2 direction. As shown in FIGS. 6 and 7, when the slide member 12 is pushed in the Y1 direction with respect to the outer wall surface member 11, the convex portion 124 is located on the most Y2 direction side of the two outer wall surface members 11 and 11. It can be fitted to each first opening 112 to be arranged. As a result, further movement of the slide member 12 in the Y1 direction is prevented, and the push surface portion 123 is sandwiched between the end portions 11d, 11d of the pair of outer wall surface members 11, 11.

Next, the specific operation of the spacer 1 at the time of expansion and contraction will be further described with reference to FIGS. 8 and 9 together with the method of using the spacer 1 when holding the two members to be held.

It protrudes from between the ends 11d and 11d of 11.

In the reduced state, the first inclined surface 111 of the outer wall surface member 11 abuts so as to overlap along the second inclined surface 121 of the slide member 12. At this time, the highest end 111b of the first inclined surface 111 of the outer wall surface member 11 is arranged in the second opening 122 of the slide member 12. Further, the highest end portion 122b of the second inclined surface 121 of the slide member 12 is arranged in the first opening portion 112 of the outer wall surface member 11. As a result, the outer wall surface member 11 in the reduced state is in the state of being closest to the outer surface surface 12a of the slide member 12, and the width W1 of the spacer 1 (the width of the pair of outer wall surface members 11) is minimized. Further, the displacement prevention plate portions 113, 113 of the outer wall surface members 11, 11 are alternately combined along the Y1-Y2 direction as shown in FIG.

Next, by further inserting the spacer 1, as shown in FIG. 8, the end portions 11e and 11e of the outer wall surface members 11 and 11 on the leading side in the insertion direction (Y1 direction) are arranged at the end of the insertion direction. It is brought into contact with the abutting surface E2 to be formed (second step).

Further, by pushing the slide member 12 in the Y1 direction using the push surface portion 123, the slide member 12 is relatively moved in the Y1 direction with respect to the outer wall surface members 11 and 11. Since the push surface portion 123 is formed wider than the slide member 12 on the tail side of the slide member 12 along the push-in direction (Y1 direction), the push surface portion 123 can be used to easily push the slide member 12 in. Can be operated.

As the slide member 12 moves in the Y1 direction, the first inclined surface 111 of the outer wall surface member 11 slides while being guided along the second inclined surface 121 of the slide member 12. As a result, as shown in FIG. 9, the outer wall surface members 11 and 11 gradually start to move in the X1 direction and the X2 direction away from the slide member 12.

When the slide member 12 is pushed in the Y1 direction to the extent that it abuts on the abutting surface E2, the highest end 111b of the first inclined surface 111 becomes the highest end 121b of the second inclined surface 121 as shown in FIGS. 7 and 10. Ride up. As a result, the outer wall surface member 11 and the slide member 12 overlap each other with the highest end portions 111b and 121b of the first inclined surface 111 and the second inclined surface 121, and the outer wall surface member 11 is from the outer surface 12a of the slide member 12. The most separated, the width W1 between the pair of outer wall surface members 11 is maximum. As a result, the outer wall surface members 11 and 11 are in the expanded state, come into contact with the holding target surfaces E1 and E1, respectively, and apply a pressing load to the holding target members E and E, respectively. The holding target members E and E pressed against the pair of outer wall surface members 11 and 11 come into contact with other members or other surfaces (not shown) arranged in the pressing direction, whereby these members or surfaces and the spacer 1 It is held between (third step).

Here, as shown in FIG. 10, the width W1 of the spacer 1 in the expanded state is set so that W1> W2 is slightly larger than the maximum separation distance W2 between the two holding target surfaces E1 and E1. Will be done. This is set by appropriately adjusting the protruding heights of the highest end portions 111b and 121b of the first inclined surface 111 and the second inclined surface 121. As a result, the pair of outer wall surface members 11 and 11 in the expanded state abut on the two holding target surfaces E1 and E1, and further, as shown by the white arrows in FIG. 10, the holding target surfaces E1 and E1 are further brought into contact with each other. An appropriate pressing load can be applied in the direction of increasing the distance between them.

Further, the first inclined surface 111 of the outer wall surface member 11 and the second inclined surface 121 of the slide member 12 corresponding thereto are arranged at equal intervals along the moving direction (Y1-Y2 direction) of the slide member 12. Therefore, it is possible to apply an even pressing load to the holding target surface E1 by the outer wall surface member 11. Moreover, since the first inclined surface 111 and the second inclined surface 121 in the deployed state overlap each other with the highest end portions 111b and 121b made of flat surfaces, the holding target surfaces E1 and E1 can be supported in a columnar shape. Therefore, the spacer 1 can stably hold the objects to be held E and E even when a large pressing load is applied by the outer wall surface members 11 and 11 in the deployed state.

Further, as shown in FIGS. 6, 7, and 10, the push surface portion 123 in the expanded state forms a flush end surface on the Y2 direction side of the spacer 1, so that the push surface portion 123 is in a flush state. By confirming that, it can be easily confirmed that the spacer 1 is in the expanded state.

When the spacer 1 is removed by releasing the pressing against the holding target surfaces E1 and E1, the slide member 12 of the spacer 1 in the expanded state is used in the pressing surface portion 123 in the direction opposite to the insertion direction with respect to the outer wall surface member 11. Remove it by moving it relatively in the (Y2 direction). When the slide member 12 is removed from between the outer wall surface members 11 and 11, the outer wall surface members 11 and 11 are in a free state, so that they can be easily pulled out from between the holding target members E and E.

As described above, according to this spacer 1, the outer wall surface member 11 is brought into contact with the holding target surface E1 simply by moving the slide member 12 in the pushing direction to unfold the pair of outer wall surface members 11 and 11. Since the pressing load can be applied to the holding target member E, the holding target member E can be held quickly and easily. Moreover, when the spacer 1 is inserted between the two holding target members E and E, the spacer 1 is in a reduced state, so that the spacer 1 can be easily inserted even in a narrow space. The spacer 1 when not in use can be stored compactly by reducing it. Further, the spacer 1 can be used repeatedly. Further, since the outer wall surface member 11 in the unfolding operation only moves in the direction away from the slide member 12 and hardly moves in the surface direction with respect to the holding target surface E1, the holding target surface E1 and the outer wall surface member 11 It does not rub against and is not damaged by rubbing the holding target surface E1.

At least one of the first inclined surface 111 of the outer wall surface member 11 and the second inclined surface 121 of the slide member 12 may be formed in a convex curved shape along the inclined direction (Y1-Y2 direction). FIG. 11 shows an example in which the second inclined surface 121 of the slide member 12 is formed in a convex curved shape along the inclined direction. As a result, the contact portion of the outer wall surface member 11 with the first inclined surface 111 becomes close to point contact. Therefore, the frictional resistance between the first inclined surface 111 and the second inclined surface 121 can be reduced, and the slide member 12 can be smoothly moved during the unfolding operation. A similar convex curved inclined surface may be provided on the first inclined surface 111 of the outer wall surface member 11, or may be provided on both the first inclined surface 111 and the second inclined surface 121.

The spacer 1 may have an operation unit for pulling out the slide member 12 from between the outer wall surface members 11 and 11. FIG. 12 is a perspective view showing an example of the operation unit.
The operation unit shown in FIG. 12 is composed of a through hole 125 provided in the push surface portion 123. Using a jig 100 having a hook-shaped portion 101 that can be inserted into the through hole 125, the hook-shaped portion 101 is inserted and locked in the through hole 125, and then the jig 100 is pulled toward the outside to remove the slide member 12. It can be pulled out from between the wall surface members 11 and 11. Compared to the case where the operating portion is formed by a protruding portion such as a knob and the protruding portion is pulled by a tool such as a finger or pliers, the through hole 125 does not form a protruding portion in the spacer 1 in the expanded state. ..

The spacer 1 may be provided with a locking mechanism that locks the outer wall surface members 11 and 11 and the slide member 12 in the unfolded state. FIG. 13 shows an example of the first locking mechanism provided on the spacer 1.
The first locking mechanism is provided at the highest end 111b of the first inclined surface 111 of the outer wall surface member 11 and the highest end 121b of the second inclined surface 121 of the slide member 12. In the present embodiment, the concave portion 111c is provided at the highest end 111b of the first inclined surface 111, and the convex portion 121c having a shape corresponding to the concave portion 111c is provided at the highest end 121b of the second inclined surface 121. The concave portion 111c and the convex portion 121c are adapted to engage with each other unevenly when the highest end portions 111b and 121b overlap each other (when they are in the expanded state).

The first locking mechanism restricts the relative movement of the pair of outer wall surface members 11 and 11 and the slide member 12 by fitting the concave portion 111c and the convex portion 121c, and locks the spacer 1 in the expanded state. do. As a result, the outer wall surface member 11 of the spacer 1 can hold the pressed state against the holding target surface E1. Further, the concave portion 111c and the convex portion 121c are fitted with a "click" sound or feel, so that the operator can easily perceive that the spacer 1 is in the unfolded state.

The concave portion 111c and the convex portion 121c shown in the present embodiment are curved in an arc shape along the Y1-Y2 direction. Therefore, the concave portion 111c and the convex portion 121c can smoothly perform either the fitting operation or the fitting release operation by moving the slide member 12. At least one pair of the first inclined surface 111 and the second inclined surface 121 having such a first locking mechanism may be used in the spacer 1.

FIG. 14 shows an example of a second locking mechanism provided on the spacer 1.
The second locking mechanism is provided on the end portions 11d, 11d of the outer wall surface members 11, 11 and the push surface portion 123 of the slide member 12. In the present embodiment, the convex portions 11f and 11f are provided on the end portions 11d and 11d of the outer wall surface members 11 and 11, and the convex portions 11f correspond to both end faces of the push surface portion 123 facing the end portions 11d and 11d. A concave portion 123a having a shape is provided. The convex portion 11f and the concave portion 123a are adapted to engage with each other in an uneven manner when the outer wall surface members 11 and 11 are in the expanded state.

Similarly to the first locking mechanism, the second locking mechanism also limits the relative movement of the pair of outer wall surface members 11 and 11 and the sliding member 12 by fitting the convex portion 11f and the concave portion 123a. However, since the spacer 1 is locked in the expanded state, the same effect as that of the first locking mechanism can be obtained. The spacer 1 may be provided with only one of a first locking mechanism and a second locking mechanism, or may be provided with both a first locking mechanism and a second locking mechanism.

Next, a specific application example of the spacer 1 described above will be described.
15 to 17 show an example in which the spacer 1 according to the present invention is applied to a battery device. FIG. 15 is a perspective view showing a part of the battery device according to the present invention in an exploded manner. FIG. 16 is a perspective view showing a part of a battery cell group in the battery device according to the present invention in an exploded manner. FIG. 17 is a front view showing the internal structure of the battery device according to the present invention. The directions shown in FIGS. 15 to 17 correspond to the directions shown in FIGS. 1 to 14.
The battery device 2 shown in the present embodiment has an exterior body 20, a battery cell group 3 housed in the exterior body 20, and a spacer 1 housed in the exterior body 20.

The exterior body 20 is formed in a square cylinder shape by a rigid body such as aluminum or an aluminum alloy. Both ends of the exterior body 20 in the length direction (Y1-Y2 direction) are opened in a horizontally long rectangular shape. The exterior body 20 has an upper wall 21, a lower wall 22, and two side walls 23 and 23 facing each other in the X1-X2 direction.

The two side walls 23, 23 are provided with temperature control medium flow paths 24, 24 through which the temperature control medium flows, respectively. As a result, the inner surface 23a of the side wall 23 constitutes a heat exchange surface with the temperature control medium in the temperature control medium flow path 24. The temperature control medium flow path 24 in each side wall 23 extends over the entire length of the exterior body 20 in the length direction.

As the temperature control medium, generally, cooling air or a cooling liquid for cooling the battery cell described later housed in the exterior body 20 is used, but if necessary, a predetermined temperature for heating the battery cell is used. Air or liquid heated to a temperature can also be used.

The temperature control medium flow path 24 shown in the present embodiment is provided inside the side wall 23. Therefore, it is not necessary to process a groove or the like for constructing the temperature control medium flow path 24 in the exterior body 20 afterwards, and the exterior body 20 can be compactly configured, so that the battery device 2 is compact. It is possible to change. Further, although not shown, the temperature control medium flow path 24 inside the side wall 23 may be configured by, for example, a groove recessed from the outside of the side wall 23. In this case, by covering the groove from the outside of the side wall 23 with a plate or the like, a flow path through which the temperature control medium can flow is configured inside the side wall 23. Further, the temperature control medium flow path 24 inside the side wall 23 may be formed by a pipe having heat transfer property. In this case, the side wall 23 provided with the temperature control medium flow path 24 is configured by burying or fixing the pipe to the side wall 23 so as to be heat exchangeable.

Such an exterior body 20 can be formed of an extruded product having the Y1-Y2 direction as the extrusion direction by forming the exterior body 20 into the same shape along the Y1-Y2 direction. Thereby, the exterior body 20 can be easily formed. Further, since the tubular exterior body 20 made of an extruded product does not have a joint portion in which plate materials are joined to each other, assembly variation and thermal strain due to the joint portion do not occur. Moreover, the stress when the battery cell group 3 is pressed toward the side wall 23 by the spacer 1 does not concentrate on the joint portion and cause distortion. Therefore, it is possible to configure the battery device 2 having the exterior body 20 having a stable shape.

As shown in FIGS. 15 and 16, the battery cell group 3 is configured by stacking a plurality of rectangular parallelepiped battery cells 30 made of, for example, lithium ion secondary batteries along the Y1-Y2 direction. Although not shown in FIGS. 15 and 16, insulating separators are arranged between the battery cells 30 and 30 adjacent to each other in the stacking direction, and are sandwiched by the adjacent battery cells 30 and 30. The battery cell 30 is configured by accommodating an electrode body in a cell case made of aluminum, an aluminum alloy, or the like, and has a pair of positive and negative electrode terminals 31, 31 on the upper surface. The electrode terminals 31, 31 of the two battery cells 30, 30 adjacent to each other in the stacking direction are electrically connected to each other by the bus bar 32. As a result, all the battery cells 30 of the battery cell group 3 are electrically connected in series or in parallel.

The battery cell group 3 composed of the plurality of stacked battery cells 30 is inserted into the exterior body 20 while sliding along the Y1-Y2 direction. In order to maintain the stacked state of each battery cell 30, the battery cell group 3 may be integrated by collectively restraining the stacked battery cells 30 with a restraint band or the like (not shown). The battery device 2 of the present embodiment accommodates two battery cell groups 3 and 3 juxtaposed in the X1-X2 directions in the exterior body 20.

A heat transfer sheet 25 is arranged between the battery cell group 3 and the inner surface 23a of the side wall 23. The heat transfer sheet 25 may be formed in a long length along the stacking direction of the battery cells 30, or may be divided into a plurality of pieces corresponding to each battery cell 30. Further, the heat transfer sheet 25 before the battery cell group 3 is housed in the exterior body 20 may be previously attached to the battery cell 30 or may be previously attached to the inner surface 23a of the side wall 23. .. The heat transfer sheet 25 is brought into close contact with both the battery cells 30 and the inner surface 23a of the side wall 23 by pressing the battery cell group 3 toward the side wall 23 by the spacer 1 described later. This stabilizes the heat exchangeable contact state between each battery cell 30 and the inner surface 23a of the side wall 23, and at the same time enables more efficient heat exchange.

The battery cells 3 and 3 housed in the exterior body 20 are fastened in the exterior body 20 along the Y1-Y2 direction by the end plates 26 arranged at both ends of the exterior body 20 in the Y1-Y2 direction. It is housed in a state of being. FIG. 15 shows only one of the two end plates 26, 26. The end plate 26 is fixed to both end faces of the exterior body 20 by bolts (not shown).

The end plate 26 is formed of a metal such as aluminum or an aluminum alloy, a resin such as engineering plastic, or a rigid body such as a composite of these metals and a resin. The end plate 26 may have a communication flow path (not shown) that communicates with the temperature control medium flow path 24 inside. As a result, the temperature control medium in the exterior body 20 can be efficiently flowed by using the end plate 26.

As shown in FIG. 17, in the battery device 2, the spacer 1 is arranged between the two battery cell groups 3 and 3 in the exterior body 20. In the battery device 2 shown in the present embodiment, after one end surface (end surface on the Y1 direction side) of the exterior body 20 is sealed by the end plate 26, two battery cell groups 3 and 3 are housed in the exterior body 20. Will be done. After that, the spacer 1 in the reduced state is inserted between the battery cell groups 3 and 3, as shown in FIGS. 4 and 8. At this time, the spacer 1 is inserted into the exterior body 20 along the Y1 direction from the side where the push surface portion 123 is not arranged.

Since the reduced spacer 1 inserted between the battery cell groups 3 and 3 abuts on the end plate 26, after that, as described above, the slide member 12 is pushed in to push the pair of outer wall surface members 11 and 11. By unfolding, as shown by the white arrow in FIG. 17, the two battery cell groups 3 and 3 can be separated and pressed against the two opposite side walls 23 and 23, respectively. That is, in this case, the surface facing each other between the two battery cell groups 3 and 3 is the surface to be held. Since the spacer 1 can collectively apply a pressing load to each of the battery cells 30 of the battery cell groups 3 and 3 simply by moving the slide member 12 in the Y1 direction and deploying the spacer 1, the battery cell group 3 3 can be quickly and easily held and accommodated in the exterior body 20. Moreover, according to this configuration, it is possible to simultaneously hold the two battery cell groups 3 and 3 in the exterior body 20 with only one spacer 1.

Here, the arrangement relationship between each battery cell 30 of the battery cell group 3 and the first inclined surface 111 and the second inclined surface 121 of the spacer 1 will be described with reference to FIG. FIG. 18 is a diagram showing a portion of the arrangement relationship between the spacer and the battery cell in the battery device according to the present invention in a cross-sectional view of the spacer.
As shown in FIG. 18, the spacer 1 in the expanded state includes the highest end portion 111b of the first inclined surface 111 of the outer wall surface members 11 and 11 and the highest end portion 121b of the second inclined surface 121 of the slide member 12. Are overlapped with each other, and the overlapping portions of the highest end portions 111b and 121b are arranged one-to-one at the positions of the battery cells 30 constituting the battery cell group 3. Therefore, the contact portion between the outer wall surface member 11 and the battery cell 30 is supported in a columnar shape by the overlapping portion between the highest end portions 111b and 121b, so that the spacer 1 exerts a stable pressing load on the battery cell 30. Can be granted. Therefore, each battery cell 30 can be efficiently pressed toward the side walls 23, 23, and more efficient heat exchange with the temperature control medium becomes possible.

The two battery cell groups 3 and 3 in the exterior body 20 can also be pressed by one spacer 1 each. 19A and 19B are diagrams illustrating other arrangement relationships between the spacer and the battery cell group in the battery device according to the present invention. The parts having the same reference numerals as those in FIGS. 15 to 17 indicate parts having the same configuration. The above explanations are used for those explanations, and are omitted here.

Between the two battery cell groups 3 and 3 in the exterior body 20, a central wall 27 for partitioning the accommodation space of the battery cell group 3 is provided in the exterior body 20. In this case, by arranging the two spacers 1 and 1 between the upper wall 21 and the battery cell groups 3 and 3, respectively, the two spacers 1 and 1 place the battery cell groups 3 and 3 on the lower wall 22, respectively. Can be pressed toward.

The battery device 2B shown in FIG. 19B has a temperature control medium flow path 24 on the central wall 27 in the exterior body 20. In this case, by arranging the two spacers 1 and 1 between the side walls 23 and 23 and the battery cell groups 3 and 3, respectively, the two spacers 1 and 1 place the battery cell groups 3 and 3 on the central wall 27, respectively. Can be pressed towards.

Although not shown, the battery device may have only one battery cell group 3 in the exterior body 20. In this case, the battery cell group 3 is pressed against any of the upper wall 21, the lower wall 22, or the side wall 23, 23 by one spacer 1.

Next, an example in which the spacer 1 is applied to the floor surface height adjusting mechanism will be described. FIG. 20A is a vertical cross-sectional view showing a part of the floor surface height adjusting mechanism in which the spacer according to the present invention is in a reduced state. FIG. 20B is a vertical cross-sectional view showing a part of the floor height adjusting mechanism in which the spacer according to the present invention is in the expanded state.
In the floor surface height adjusting mechanism, the spacer 1 is arranged on the floor surface F, and the floor plate member 200 is provided on the spacer 1. In the spacer 1, one outer wall surface member 11 is brought into contact with the floor surface F, and the other outer wall surface member 11 is brought into contact with the floor plate member 200.

As shown in FIG. 20A, the floor surface height adjusting mechanism moves the slide member 12 of the spacer 1 in the reduced state in the Y1 direction, so that the outer wall surface members 11 and 11 are shown in FIG. 20B. Is in the expanded state, and the floor plate member 200 is configured to be separated from the floor surface F. Thereby, the height of the floor plate member 200 from the floor surface F can be adjusted quickly and easily.
