PROBLEM TO BE SOLVED: To provide a working vehicle facilitating heat release in an engine bonnet getting to have a high temperature due to regeneration of DPF while maintaining the strength of the engine bonnet.SOLUTION: Heat discharge holes 13a, 13b are formed on a top plate 13 of an engine bonnet 9. Reinforcing members 21, 22 are fixed on the inside wall surface of the engine bonnet 9 so as to be located below the heat discharge holes 13a, 13b. A prescribed space 30 is provided between the reinforcing members 21, 22 and the heat discharge holes 13a, 13b and the top plate 13. Cross-sectional surfaces of the reinforcing members 21, 22 are formed each into an almost U-shape.COPYRIGHT: (C)2014,JPO&INPIT【課題】ボンネットの強度を維持しつつ、DPFの再生によって高温となったボンネット内の放熱を促進する。【解決手段】ボンネット9の天板13に排熱孔13a,13bを設け、該排熱孔13a,13bの下方に位置するように、ボンネット9の内壁面に補強部材21,22を固定する。該補強部材21,22と、排熱孔13a,13b及び天板13との間には、所定間隙30を設ける。また、前記補強部材21,22は、断面略U字状に形成される。【選択図】図6
