PROBLEM TO BE SOLVED: To provide a service vehicle prime mover structure capable of ensuring the high draw-in capability of a radiator fan and the high exhaust capability of a dust discharge fan, suppressing the overheat of an engine, and ensuring the less frequency of maintenance and inspection work.SOLUTION: The object is attained by disposing an oxidation catalyst device 11 oxidizing unburned fuel contained in exhaust gas discharged from an engine (E) in an internal region of a vehicle body above the engine (E) along a front-rear direction, disposing an outdoor-air-draw-in radiator fan (20) capable of being switched between a driven state and a stopped state and an exhaust-gas dust discharge fan (30) capable of being switched between a driven state and a stopped state between the engine (E) and a radiator (50) cooling coolant circulating in the engine (E); and providing a heat shield cover (95) between a side panel (6A) disposed a vehicle body internal side of a driver seat (6) in a side view and the oxidation catalyst device (11).

    【課題】ラジエータファンの吸入能力と排塵ファンの排気能力が高く、エンジンのオーバヒートを抑制し、保守・点検作業の頻度が少ない作業車輌の原動部構造を提供する。【解決手段】エンジン(E)の上部における機体内側の部位に、エンジン(E)から排出される排気ガス中の未燃燃料を酸化する酸化触媒装置(11)を前後方向に沿って配置し、エンジン(E)とエンジン(E)を循環する冷却水を冷やすラジエータ(50)の間に、駆動状態と停止状態に切換可能な外気吸入用のラジエータファン(20)と駆動状態と停止状態に切換可能な排気用の排塵ファン(30)を配置し、側面視において操縦席(6)における機体内側に配置されたサイドパネル(6A)と酸化触媒装置(11)の間に、遮熱カバー(95)を設けることにより解決される。【選択図】図15
