PROBLEM TO BE SOLVED: To provide a cab structure of a combine harvester whose support column-standing position is brought close to a drivers seat as much as possible, whose hood support structure is simplified, and whose support column can be supported with a strong member (for example, an engine cover) placed under an air cleaner box.SOLUTION: The cab structure of the combine harvester 1 equipped with a hood 15 for covering the upper side of the cab 8 is characterized by disposing the base portion of the support column 16 in an air cleaner box 13 disposed adjacent to the rear side of a drivers seat 7 in a penetrated state, when the support column 16 of the hood 15 is vertically disposed in the cab 8. Thereby, the standing position of the support column is brought close to the drivers seat as much as possible to simplify the hood support structure.COPYRIGHT: (C)2011,JPO&INPIT【課題】支柱の立設位置を可及的に運転シートに近付け、フード支持構造を簡略化する。また、エアクリーナボックスの下方にある強固な部材(例えば、エンジンカバー)で支柱を支持可能とする。【解決手段】運転部8の上方を覆うフード15を備えたコンバイン1において、運転部8に、フード15の支柱16を立設するにあたり、該支柱16の基部を、運転シート7の後方に隣接して配置されるエアクリーナボックス13内に貫通状に配置することにより、支柱の立設位置を可及的に運転シートに近付け、フード支持構造を簡略化する。【選択図】図2
