That is, when the cutout 60a is provided in the inner contact portion 32A3 from the connection portion with the outer shell base portion 32A1 in the outer shell bone member 32A, the square tube portion 32A4 is removed together with the inner contact portion 32A3. The accommodating part 60 which can accommodate the finding wall part 52 in the inside of the material 32 is ensured. In this case, in the present embodiment, the outer skeleton member 32A is formed of resin, so that the notch 60a for the accommodating portion 60 can be easily configured. In the present embodiment, since the outer peripheral reinforcing rib 54A and the inner peripheral reinforcing rib 54B are provided between the finding wall portion 52 and the fitting protruding portion 51a, as shown in FIG. 6, the inner shell bone member 32B. It is necessary to form a rib notch 61 in advance at the lower end of the rib, and to arrange the outer peripheral reinforcing rib 54A and the first rib portion 54B1 of the inner peripheral reinforcing rib 54B in the rib notch 61. The notch 61 for ribs is a notch formed in the lower end part of the cylinder contact part 32B2 in the inner shell member 32B, and is formed so as to open to the lower end.

  As described above, according to the cap member 50 attached to the lower end portion of the door-end aggregate 32 in a state where the finding wall portion 52 is accommodated in the accommodating portion 60, the finding surface 52b facing the room of the finding wall portion 52 is formed. It can arrange | position so that it may become on the surface substantially the same as the surface where the surface material 33 is found. The water stop member 55 held by the cap member 50 is in contact with the main door tight material 41 attached to the inner cover portion 36B2 and the main door sub-tight material 40 attached to the prospective edge material 36A, and Is located at a position facing the main tight portion 12Db in the transverse tight material 12D of the lower frame 12.

  Therefore, in a state where both the main door 20 and the child door 30 are closed, the main door tight material 41 and the main door sub-tight material 40 of the child door 30 are connected to the horizontal tight material 12D of the lower frame 12 via the water stop member 55. It becomes continuous, and the water stop property between the frame bodies 10 can be ensured. In addition, the portion facing the main tight portion 12Db of the lateral tight member 12D provided on the lower frame 12, that is, the finding surface of the surface material 22 facing the interior of the main door 20, and the finding surface of the surface material 33 facing the interior of the child door 30 In the cap member 50, a finding surface 52b (a portion below the holding portion 53b) facing the room of the finding wall portion 52 is disposed on the same surface. Thereby, there is no possibility that a gap will be generated between the main door 20 and the child door 30 and the main tight portion 12Db of the lateral tight material 12D, and water stoppage can be improved. Furthermore, since it is not necessary to perform any processing on the transverse tight material 12D, the number of handling parts does not increase, and there is no possibility that the manufacturing operation of the joinery becomes complicated and the manufacturing cost increases. The above-described operation and effect are similarly achieved between the cap member 50 attached to the upper end portion of the door-end aggregate 32 and the upper frame 11.

  In the above-described embodiment, the door-end aggregate 32 of the child door 30 is formed of resin, but the door-end aggregate may be formed of metal such as aluminum alloy or steel. . Moreover, although the door-end aggregate 32 is comprised by the outer-shell member 32A and the inner-shell member 32B, it does not necessarily need to be provided with the two bone members 32A and 32B, and a detailed structure is also a thing of implementation. Not exclusively. Further, although the cap member 50 is illustrated as having the fore cover portion 51, the finding wall portion 52, the edge cover portion 53, and the fitting protrusion portion 51a, it is of course possible to apply cap members having other configurations. . Furthermore, in the cap member 50, the finding surface 52b of the finding wall portion 52 is positioned on the same surface as the finding surface of the surface material 33, but the finding surface of the cap member is not necessarily the same as the finding surface of the surface material. There is no need to lie on the surface of the. In addition, although the fitting which comprised the dimension along the left-right direction of the main door 20 larger than the child door 30 is illustrated, so that the dimension along the left-right direction of the main door 20 may become the same as the child door 30. You may comprise, or it may comprise so that the child door 30 may become large.
