PROBLEM TO BE SOLVED: To provide a deck under a cabin capable of securing dynamic rigidity as well as weight saving effect.SOLUTION: An outer frame 30 comprises a first structure S1 and a second structure S2. A width T2 in a thickness direction of the second structure S2 is greater than a width (plate thickness t1) in a thickness direction of the first structure S1. The whole of a front face side 33 is configured by the first structure S1, while the whole of a rear face side 31 is configured by the second structure S2. At least a part of a rear side part X2 of a side face part 35 is configured by the second structure S2. A part of the side face part 35 which is not configured by the second structure S2, is configured by the first structure S1.SELECTED DRAWING: Figure 4

    【課題】キャビン下デッキの動剛性を確保でき、かつ、キャビン下デッキを軽量化する。【解決手段】外枠30は、第1構造S1と、第2構造S2と、により構成される。第2構造S2の厚さ方向の幅T2は、第1構造S1の厚さ方向の幅(板厚t1)よりも大きい。前面部33の全体は、第1構造S1により構成される。後面部31の全体は、第2構造S2により構成される。側面部35の後側X2部分の少なくとも一部は、第2構造S2により構成される。側面部35のうち第2構造S2により構成されない部分は、第1構造S1により構成される。【選択図】図4
