PROBLEM TO BE SOLVED: To easily attach/detach an engine mounted within an engine compartment under a drivers seat.SOLUTION: In the working vehicle with the engine (E) mounted within the engine compartment (7) formed under the drivers seat (5), a rear cover frame (12) on the rear side of the engine compartment (7) is made detachable, so that the engine (E) is drawn out rearward by detaching the rear cover frame (12) and opening the rear side of the engine compartment (7). In addition, an electric component housing box (11) is disposed above the engine compartment (7), and an electric equipment mounting panel (14), in which an electrical component (9) connected to the engine (E) by wiring is mounted, is disposed inside the electric equipment housing box (11). The rear cover frame (12) serves also as a rear surface cover of the electric equipment housing box (11). The electric equipment mounting panel (14) is taken out rearward by detaching the rear cover frame (12).COPYRIGHT: (C)2012,JPO&INPIT【課題】運転席下方のエンジンルーム内に搭載されたエンジンの着脱容易化を図る。【解決手段】運転席(5)の下方に形成したエンジンルーム(7)内にエンジン(E)を搭載した作業車両において、エンジンルーム(7)の後部側の後部カバー枠(12)を着脱自在に構成し、後部カバー枠(12)を取外し、エンジンルーム(7)の後部側を開放してエンジン(E)を後方へ引き出す構成とする。また、エンジンルーム(7)の上部に電装収納ボックス(11)を設け、電装収納ボックス(11)内にエンジン(E)と配線で接続した電装部品(9)を取付けた電装取付パネル(14)を設け、後部カバー枠(12)は、電装収納ボックス(11)の後面カバーを兼用する構成とし、後部カバー枠(12)を取外して電装取付パネル(14)を後方へ取出す構成とする。【選択図】 図3
