And the trunk edge 7 can be smoothly fitted to the trunk edge receiving member 6.

  Further, since the trunk rim 7 can be supported by the inner lip portion 67, the area for supporting the trunk rim 7 can be enlarged. For this reason, the support force of the trunk edge 7 in the trunk edge receiving member 6 can be improved.

  Further, since the trunk edge 7 has a simple shape in which only the locking lip 74 protrudes inward, as shown in FIG. 7, the two trunk edges 7a and the trunk edge 7b are fitted to face each other. Moreover, since it can pack up compactly with the packing materials 100, such as a string and a sheet | seat, portability can be improved. Similarly, since the trunk edge 7 and the trunk edge receiving member 6 can be formed by a simple bending process, the wall thickness can be increased. In particular, since the trunk edge 7 can be formed by three simple bending processes, it can be easily thickened. Further, by increasing the thickness of the trunk edge 7 and the trunk edge receiving member 6, the strength of the base member 1 is remarkably improved, so that the number of the trunk edge receiving member 6 and the trunk edge 7 attached to the housing 2 is reduced. Thus, the cost of the base member 1 can be reduced.

  According to the mounting method of the base member 1 according to the present embodiment, the locking lip 74 is brought into contact with the trunk edge receiving member 6 from the housing 2 side to rotate the trunk edge 7, and 7 can be fitted to the trunk edge receiving member 6. In addition, when the trunk edge 7 is fitted to the trunk edge receiving member 6 in this manner, the locking lip 74 is locked to the trunk edge receiving member 6, so that the other side wall 63 and the other side wall 73 are connected. The barrel edge 7 is attached to the barrel edge receiving member 6 only by screwing. That is, the barrel edge 7 can be attached to the trunk edge receiving member 6 by screwing only one side of the base member 1. Thereby, the work man-hour for fixing the trunk edge 7 and the trunk edge receiving member 6 can be reduced, and the workability at the time of attaching the trunk edge 7 to the trunk edge receiving member 6 can be improved. . In addition, the work space on the side of the one side wall 72 (one side wall 62) can be reduced, so that the workability particularly at the corners can be significantly improved.

  Furthermore, since the building 10 according to the present embodiment employs the base member 1 with good workability as described above, the workability of the building 10 as a whole can be improved.

  The present invention is not limited to the above embodiment.
