Abstract
Description
図1は、油圧ショベル100の側面図である。図2は、油圧ショベル100の側方斜視図である。図2では、エンジン室カバー7の一部が取り外されている。
図3は、作動油タンク10の斜視図である。図4は、作動油タンク10の側面図である。
図6は、ブリーザホース16の内部に形成された空気流路30の構成を示す模式図である。
(1)ブリーザホース16は、ブリーザ弁15に連なる第1流路31と、第1流路31から分岐する第2流路32及び第3流路33とを形成する。第2流路32は、第1流路31と延伸方向が異なる。第2流路32は開放端を有し、第3流路33は閉塞端を有する。
上記実施形態において、第1流路31は、分岐点34に向かって下方に延び、第2流路32は、分岐点34から開放端に向かって下方に傾斜し、第3流路33は、分岐点34から閉塞端に向かって上方に傾斜することとしたが、異音の発生を抑制するという観点からはこれに限られるものではない。第2流路32の延伸方向と第1流路31の延伸方向が異なっている限り、第1流路31、第2流路32及び第3流路33の形状及び配置は適宜変更可能である。
