    Therefore, according to the rainwater storage device G described above, the rectangular parallelepiped main body 10 includes the first frame member 11, the second frame member 12, the third frame member 13, and the fourth frame member 14 by the connecting means. Since they are connected, before installation, as shown in FIG. 9, the first frame member 11, the second frame member 12, the third frame member 13, and the fourth frame member 14. It is flat and not bulky, does not take up space in transportation, etc., and can transport many first frame members 11, second frame members 12, third frame members 13, and fourth frame members 14, In installation, the first frame member 11, the second frame member 12, the third frame member 13, and the fourth frame member 14 are connected by a connecting means to form a rectangular parallelepiped main body 10. In addition to being strong, it takes a lot of internal space that is a space for storing rainwater inside the rectangular solid body 10. Bets can be, since the main body 10 of a rectangular parallelepiped shape in the recess 2 formed by digging down the ground are arranged in the vertical and or horizontal and vertical, and that also stable structurally.

    The connecting means is not limited to that shown in FIGS. 4 to 8 described above. For example, in FIGS. 4 to 8, the first concave portion 11b and the fourth convex portion 14c are omitted, and the fourth means The contact surface 14A of the frame member 14 and the contact surface 11A of the first frame member 11 may be brought into contact with each other. As shown in FIG. 10, the second frame member 12 and the third frame The member 13 may be foldably connected by the second connecting portion 100. The first frame member 11 and the second frame member 12 can be bent freely by a first connection portion (not shown, but the same as the second connection portion 100). The frame member 13 and the fourth frame member 14 are connected to each other so as to be bent by a third connecting portion (not shown, but the same as the second connecting portion 100). The frame member 14 and the first frame member 11 may be brought into contact with each other. As shown in FIG. 11, the connecting means includes the first frame member 11, the second frame member 12, and the third frame member. The frame member 13 and the fourth frame member 14 are arranged in an annular shape, and an adhesive is applied to the contact surfaces (12A and 11B, 13A and 12B, 14A and 13B, and 14B and 11A) to connect them. Anyway.

Further, the rectangular parallelepiped main body 10 is not limited to the one described above, and may be, for example, those shown in FIGS. 12 to 14.
That is, 11M is a V-shaped first protrusion provided so as to protrude from the first frame member 11, and 12M is a V-shape provided so as to protrude from the second frame member 12. The shape-shaped second protrusion and 13M protrude from the third frame member 13, and the V-shaped third protrusion and 14M protrude from the fourth frame member. The V-shaped fourth protrusion provided on the rectangular parallelepiped body 10 includes a V-shaped first protrusion 11M, a V-shaped second protrusion 12M, and a V-shaped third protrusion. The protrusion 13M and the V-shaped fourth protrusion 14M come into contact with each other to form an X-shaped member. More preferably, as shown in FIG. 14, the tip of the V-shaped first projection 11M, the tip of the V-shaped second projection 12M, and the V-shaped third projection 1
The 3M tip and the tip of the V-shaped fourth protrusion 14M are brought into contact with each other so that an X-shaped member is formed. As a result, the strength of the rectangular parallelepiped main body 10 can be increased.

Further, the rectangular parallelepiped main body 10 is not limited to the above-described one, and for example, the one shown in FIG.
That is, the rectangular parallelepiped main body 10 is configured by connecting the first L-shaped member L1 and the second L-shaped member L2 by the connecting means at the installation site.
The first L-shaped member L1 has an opening inside (not shown, but in FIG.
a second rectangular shape having an opening (not shown, but in FIG. 4, the opening 12a) joined orthogonally to the rectangular first frame member 11 having a) Frame member 12
In addition, the second L-shaped member L2 has a rectangular third frame member 13 having an opening (not shown, but in FIG. 4, the opening 13a) inside. And a fourth frame member 14 having a rectangular shape having an opening (not shown, but an opening 14a in FIG. 4) inside. The means is the same as that in the above-described embodiment, and is, for example, the concave portion 11b and the convex portion 14c, and the concave portion 13b and the convex portion 12c.

Further, as shown in FIG. 16, the rectangular parallelepiped main body 10 is configured by arranging the same rectangular parallelepiped main body 10 vertically and / or vertically and horizontally.
