PROBLEM TO BE SOLVED: To provide a combine-harvester capable of increasing the capacity of a fuel tank arranged in a space formed between the back side lower portion of a thresher and the front side lower portion of a straw discharging processor, and easily attaching and detaching the fuel tank.SOLUTION: A frame 1A extending in a longitudinal direction is provided at the rear portion of an airframe frame, and a left side frame 1B and a right side frame 1C which extend from the left side portion and the right side portion of the frame 1A are provided. A left side support plate 30 is fixed on the left side frame 1B, and a right side support plate 32 is fixed on the right side frame 1C. A fuel tank is mounted in the space which is formed between the back side lower portion of a thresher and the front side lower portion of a straw discharging processor. An expanding portion 20C bulging toward the lower side is formed at a transverse central part of a bottom wall 20B of the fuel tank. On the left side support plate 30, a portion of the bottom wall 20B which is positioned on the lefthand side of the expanding portion 20C is placed. On the right side support plate 32, a portion of the bottom wall 20B which is positioned on the righthand side of the expanding portion 20C is placed.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2018,JPO&INPIT【課題】脱穀装置の後側下部と排藁処理装置の前側下部との間に形成される空間に配置される燃料タンクの容量を増大させると共に、燃料タンクを容易に着脱可能なコンバインを提供する。【解決手段】機体フレームの後部に左右方向に延在するフレーム１Ａを設け、フレーム１Ａの左側部及び右側部から各々後側に向かって延在する左側フレーム１Ｂと右側フレーム１Ｃを設け、左側フレーム１Ｂに左側支持プレート３０を固定し、右側フレーム１Ｃに右側支持プレート３２を固定し、脱穀装置の後側下部と排藁処理装置の前側下部との間に形成される空間に燃料タンクを設け、燃料タンクの底壁２０Ｂの左右方向の中央部に下側に向かって膨れた膨出部２０Ｃを形成し、左側支持プレート３０に膨出部２０Ｃよりも左側に位置する底壁２０Ｂの部位を載置し、右側支持プレート３２に膨出部２０Ｃよりも右側に位置する底壁２０Ｂの部位を載置した。【選択図】図７
