UREA WATER TANK
To provide an urea water tank in which urea water can be prevented from accumulating in a breather pipe disposed in a manner of penetrating through a top surface of a tank main body.SOLUTION: A urea water tank 1 mounted on a work machine comprises: a tank main body 2 including a bottom surface portion 21, a side surface portion 23, and a portion 25; and a breather pipe 5 disposed in a manner of penetrating through the top surface portion 25. A first opening end at one end side of the breather pipe 5 is positioned outside the tank main body 2. A second opening end at the other end side of the breather pipe 5 is positioned in a space formed at an upper side with respect to a maximum liquid level of the urea water stored in an internal space, of the internal space of the tank main body 2. In the case in which the tank main body 2 is in a horizontal state, an upper pipe portion positioned at an upper side of the top surface portion 25 of the breather pipe 5 includes an upper inclined portion extended obliquely upward from a side of the top surface portion 25 and does not include a horizontally extending horizontal region.SELECTED DRAWING: Figure 1
【課題】タンク本体の上面を貫通するように設けられたブリーザパイプの管内に尿素水が滞留するのを防止することが可能な尿素水タンクの提供。【解決手段】作業機械に搭載される尿素水タンク１は、底面部２１と側面部２３と上面部２５とを含むタンク本体２と、上面部２５を貫通するように設けられるブリーザパイプ５とを備える。ブリーザパイプ５のうち一端側の第一開口端は、タンク本体２の外側に配置される。ブリーザパイプ５のうち他端側の第二開口端は、タンク本体２の内部空間のうち当該内部空間に貯留された尿素水の最大液位よりも上側に形成される空間に配置される。タンク本体２が水平状態にある場合において、ブリーザパイプ５のうち上面部２５の上側に配置される上側パイプ部は、上面部２５の側から斜め上方に延伸する上方傾斜部を含む一方、水平に延伸する水平領域を含まない。【選択図】図１
