CHASSIS STRUCTURE

To provide a chassis structure capable of suppressing a mechanical load received by a deck.SOLUTION: A chassis 15 includes a pair of right-and-left main sills constituted of a front side main sill 102 and a rear side main sill 155 connected respectively to a pair of right-and-left side frames 16 and extending in a cross direction, cross sills constituted of a front side cross sill 171, a center cross sill 172 and a rear side cross sill 173 bridged over the pair of right-and-left main sills, and a deck 100 connected to the main sills and the cross sills, and covering the main sills and the cross sills from above, in which the deck 100 is constituted of a corrugated steel sheet where a crest part M1 and a trough V1 extending respectively in one direction are aligned alternately.SELECTED DRAWING: Figure 2 【課題】デッキが受ける機械的な負荷を抑えることのできるシャーシ構造を提供する。【解決手段】シャーシ１５は、左右一対のサイドフレーム１６の各々に連結されて車両の前後方向に延びる前側縦根太１０２および後側縦根太１５５で構成される左右一対の縦根太と、左右一対の縦根太に架け渡される前側横根太１７１、中央横根太１７２、および、後側横根太１７３とで構成される横根太と、縦根多と横根太とに連結されて縦根太および横根太を上方から覆うデッキ１００とを備え、デッキ１００が１方向に延びる山部Ｍ１と谷部Ｖ１とが交互に並んだ波型鋼板で構成されている。【選択図】図２
