PROBLEM TO BE SOLVED: To provide a four-wheel drive working vehicle which is designed to arrange a center of gravity of a body lower than ever by devising arrangement positions of an engine, electric motor and battery to be compact and arranging the electric motor and the battery at low positions.SOLUTION: A four-wheel drive working vehicle comprises: an operation part including a driver's seat 22; a prime mover part including an engine and an electric motor 8; and a vehicle body frame for supporting the operation part and the prime mover part. The vehicle body frame comprises: a front machine frame including the operation part; and a rear machine frame disposed behind the front machine frame at a higher position than the floor surface of the operation part. The engine is arranged under the rear machine frame. A battery 9 and the electric motor 8 are mounted above the front machine frame, with a gravity G2 of an assembly of battery 9 and electric motor 8 arranged under a position of gravity G1 of the whole traveling body.SELECTED DRAWING: Figure 7

    【課題】エンジン、電動モータ、及びバッテリの配設位置を工夫して、コンパクトに、かつ電動モータ、及びバッテリを低位置に配置して、機体の低重心化を図る。【解決手段】運転座席22が設けられた運転部と、エンジン及び電動モータ8を配備した原動部と、その運転部及び原動部を支持する車体フレームが備えられ、車体フレームは、運転部が設けられた前部機枠と、運転部の床面よりも高い位置で前部機枠の後方側に後部機枠を備え、エンジンが後部機枠の下側に配備され、バッテリ9と電動モータ8とが、前部機枠の上側で、かつ、走行機体全体の重心G1位置よりも下方側に、バッテリ9と電動モータ8の集合体の重心G2を位置させた。【選択図】図7
