PROBLEM TO BE SOLVED: To provide a rolling compaction vehicle capable of avoiding burning caused by dust entering through the outside air inlet together with the outside air and making contact with the exhaust pipe inside the heat exchanger cover, while preventing outside air from being sucked into the heat exchanger cover from within the tire house.SOLUTION: A heat exchanger 21 is arranged between an engine room 9 and an outside air lead-in chamber 20. A heat exchanger cover 26 is fixed to the lower side of the outside air lead-in chamber 20 and communicated with the outside air lead-in chamber 20. An exhaust pipe 31 of an engine 10 is extended into a tire house 15 via the inside of the outside air lead-in chamber 20 and through an exhaust through-hole 32 on a bottom wall 26c of the heat exchanger cover 26. Outside air is introduced into the outside air lead-in chamber 20 and the heat exchanger cover 26 from an outside air inlet 24 of a hood 11 and caused to circulate through a heat exchanger 21 using the negative pressure generated by the operation of the engine 10. A minimum clearance dimension L2 of an annular gap 35 between the exhaust through-hole 32 and the exhaust pipe 31 is set larger than the maximum clearance dimension L1 of the mesh on a mesh panel 25 provided on the outside air inlet 24.SELECTED DRAWING: Figure 2

    【課題】タイヤハウス内から熱交換器カバー内への外気の吸込みを防止した上で、外気導入口から外気と共に侵入するゴミが熱交換器カバー内で排気管との接触により燃える事態を回避できる転圧車両を提供する。【解決手段】エンジンルーム9と外気導入室20との間に熱交換器21を配設し、外気導入室20の下側に熱交換器カバー26を固定して外気導入室20と連通させる。エンジン10の排気管31を外気導入室20内を経由して熱交換器カバー26の底壁26cの排気貫通孔32を経てタイヤハウス15内へと延設する。エンジン10の運転で発生した負圧により、フード11の外気導入口24から外気導入室20内及び熱交換器カバー26内に外気を導入して熱交換器21を流通させる。外気導入口24に設けた網目パネル25の網目の最大隙間寸法L1に対して、排気貫通孔32と排気管31との間の環状隙間35の最小隙間寸法L2を大きく設定する。【選択図】図2
