PROBLEM TO BE SOLVED: To provide a fuel tank for a construction machine, capable of stably supplying fuel even in the rapid rippling state of a liquid surface in the tank.SOLUTION: In the top board 41a of a tank body 41 in which fuel is stored, a chuck valve 42 is provided therethrough to face a predetermined height position in the tank body 41, the surroundings of the chuck valve 42 is covered with a cylindrical cover member 47 having a bottom and extending from the top board 41a of the tank body 41, and a distribution hole 47a through which the fuel in the tank body 41 is distributed is provided in the cover member 47. Thus, even in the rapid rippling state of a liquid surface in a fuel tank 40, frequent opening/closing of the chuck valve 42 can be prevented.SELECTED DRAWING: Figure 6 【課題】タンク内の液面が激しく波立った状態でも安定的に燃料を供給できる新規な建設機械の燃料タンクの提供。【解決手段】燃料が溜められるタンク本体４１の天板４１ａに、これを貫通してタンク本体４１内の所定の高さ位置に臨むようにチェック弁４２を備え、前記チェック弁４２の周囲を前記タンク本体４１の天板４１ａから延びる有底筒状のカバー部材４７で覆うと共に、このカバー部材４７にタンク本体４１内の燃料が流通する流通穴４７ａを設ける。これによって燃料タンク４０内の液面が激しく波立った状態でもチェック弁４２が頻繁に開閉動作するのを回避できる。【選択図】図６
