  FIG. 3 is a perspective view of the rain protection device 6. As shown in the figure, the rain protection device 6 is expanded between the opening 2a and the opening / closing door 3 with the opening / closing door 3 opened 90 degrees outward. The rain protection device 6 is provided with a rain protection sheet plate 6a as a rain protection member, and the rain protection sheet plate 6a is made of a plate-like body made of, for example, acrylic, polycarbonate, foam synthetic resin or the like having waterproof properties. In addition, if this rainproof sheet board 6a is a board | plate material which has a certain degree of rigidity, an appropriate material can be employ | adopted.

  The rainproof sheet plate 6a has a substantially rectangular shape having a corner end A, a left corner end B, a hanging corner end C, a right corner end D, and sides AB, BC, CD, and DA. . The corner end A is disposed at a corner between the opening 2 a and the open / close door 3. The left corner end B and the right corner end D are disposed adjacent to the corner end A, and the hanging corner end C is disposed at the diagonal position of the corner end A, as shown in FIG. In the above, the corner end A and the right corner end D are engaged with both ends of the upper end 3 a of the open / close door 3. The corner end A may be locked not in the opening / closing door 3 but in the vicinity of the upper side of the shaft of the opening 2a.

  For example, the corner end portion A is attached with a hooked first hooking portion 6b, which is a hooked first hooking portion, and the right corner end D is attached with a hooked hooking portion 6c, which is a second hooking portion.

  The hooking portions 6 b and 6 c are locked by a pair of hooked portions 3 b formed of, for example, an annular string attached to both sides of the upper end 3 a of the open / close door 3. The hooked portion 3b, which is the first hooked portion, is provided near the shaft at the upper end of the open / close door 3 or near the shaft at the upper end of the opening 2a.

  The second hooked portion consisting of a pair is a hooked portion 3b provided at the upper end of the open / close door 3 and a hooked portion provided near the center of the horizontal frame 2b at the top of the opening 2a. And 2c.

  The above-mentioned locking is not limited to the embodiment. For example, the hooking portion 6b and the hooked portion 3b are interchanged, a surface fastener is attached to the side portion AB, and a surface fastener corresponding to the upper end 3a is attached. It can also be locked using these surface fasteners. Furthermore, for example, an eyelet hole made of metal or synthetic resin may be attached to the corner end portions A and D, and locking may be performed by a cord connecting the hooked portion 3b and the eyelet holes. Alternatively, hooks, rings, cords, hook and loop fasteners, etc. can be combined as appropriate.

  Near the left corner end B and the right corner end D, the end of a cord 6 d such as a rope is fixed. The attachment point for attaching the end of the cord 6d to the vicinity of the left corner end B and the right corner end D of the rainproof sheet 6a is substantially the same as the attachment point for the hook 6c.
