PROBLEM TO BE SOLVED: To solve problems, for example, in a conventional transport vehicle or the like including a vertically-mounted engine, an axle, and a mechanical transmission gear and hydraulic infinite variable speed device disposed between the engine and axle, the engine being a heavy object is disposed on one side of lateral sides, therefore lateral weight balance cannot be preferably held and results in reduction of travel stability, and the engine is constructed individually from the mechanical transmission gear and hydraulic infinite variable speed device, so that a space and fixing member for installing the engine are required, resulting in increase of size increase of vehicle and component cost.SOLUTION: An engine 4 is disposed on an approximate center of a vehicle width of a transport vehicle 1, and the engine 4 is integrated with a mechanical transmission gear 5 to which a hydraulic infinite variable speed device 6 for forming an axle drive unit 3, and plural first PTO axes 105 and second PTO axes 106 for outputting PTO motive force from the mechanical transmission gear 5 are disposed in a dispersed state, in left and right sides, sandwiching the engine 4.
【課題】従来より、縦置きエンジンと、車軸と、エンジンから車軸までの間に配設する機械式伝動装置・油圧式無段変速装置とを配設した運搬車等では、重量物のエンジンが左右一側に寄せて配設されており、左右重量バランスを良好に保つことができずに走行安定性が低下したり、エンジンが、機械式伝動装置・油圧式無段変速装置を備えるトランスミッションとは全く別体に構成されており、エンジンの設置に必要な空間や固定部材が別途に必要となって、車両の大型化・部品コストが増加する、という問題があった。【解決手段】運搬車1の車幅の略中央にエンジン4を配設し、エンジン4を、油圧式無段変速装置6を装着した機械式伝動装置5と一体化させて車軸駆動ユニット3を形成すると共に、機械式伝動装置5からPTO動力を出力する複数の第一PTO軸105・第二PTO軸106を、エンジン4を挟んで左右に分散配置した。【選択図】図1
