  For example, in the present embodiment, the rain gutter structure 40 includes the gutter receiving member 45 that receives the water guide member 44 that discharges rain water to the outside through the opening 42 of the column 6 from the gutter 41 and supports the gutter 41. However, it is formed with a receiving portion 50 and a holding portion 51 similar to those of the present embodiment, and is inserted and arranged in the support column 6 and directly receives rainwater flowing through the support column 6. The rain gutter structure 40 may be configured by including a rain water receiving member that discharges the rain water to the outside through the six opening portions 42.

  In other words, unlike the present embodiment, the rod 41 and the water guide member 44 are not used, the hollow portion 27 of the column 6 is used as a rod, and rainwater flowing down the hollow portion 27 of the column 6 is received and the opening of the column 6 is opened. The rain gutter structure 40 may be configured with a rain water receiving member that is discharged from the portion 42 to the outside. Even in this case, it is necessary to form the rainwater receiving member and the column 6 so that the entire outer peripheral surface of the receiving portion 50 of the rainwater receiving member is in close contact with the entire inner surface of the hollow portion 27 of the column 6. Of course, it is possible to obtain the same effects as the present embodiment.

  In the present embodiment, the opening 42 is formed with a gap between the lower end 47b of the adjacent upper column side panel piece 47a and the upper end 47c of the lower column side panel piece 47a. The position of the opening 42 may be freely changed by replacing the column side panel piece 47a that has been previously formed through the opening 42 with another column side panel piece 47a. Even in this case, it is possible to obtain the same effect as that of the present embodiment.

  In the present embodiment, the building exterior structure B is described as a garden room type building exterior structure. However, the building exterior structure according to the present invention may be a side-through type building exterior structure. Moreover, although the front wall part 1 (and side wall part 3) demonstrated as what is provided with the waist wall 15, it does not need to limit to this and this invention is a building external structure of the type shown in FIG.
