To provide a hook accommodating structure for a construction machine that can hold hooks further securely that are stored in a bucket link containment space in the construction machine.SOLUTION: A hook accommodating structure of a hydraulic excavator comprises a bucket link 5, a hook 7, and a holding unit 9. The holding unit 9 includes a fixed holding member 91 arranged on the left side of the hook 7 at a storage position PS1, a moving holding member 93 arranged on the right side of the hook 7, and an urging member 95. The fixed holding member 91 has a retaining portion 911 having a convex shape toward the inside of the hook portion of the hook 7 at the storage position PS1. The moving holding member 93 is configured to be movable in a direction away from the fixed holding member 91 against the urging force of the urging member 95. The hook 7 at the storage position PS1 has the retaining portion 911 arranged inside the hook portion, and the moving holding member 93 is urged to the side of the fixed holding member 91 by the urging member 95.SELECTED DRAWING: Figure 6

    【課題】建設機械においてバケットリンクの格納空間に格納されるフックをより確実に保持することが可能な建設機械のフック格納構造の提供。【解決手段】油圧ショベルのフック格納構造は、バケットリンク5と、フック7と、保持ユニット9とを備える。保持ユニット9は、格納位置PS1にあるフック7の左側方に配置される固定保持部材91と、フック7の右側方に配置される移動保持部材93と、付勢部材95とを備える。固定保持部材91は、格納位置PS1にあるフック7の鉤部内側に向けて凸形状をなす抜止部911を有する。移動保持部材93は、付勢部材95による付勢力に対抗して固定保持部材91から離れる方向に移動可能に構成される。格納位置PS1にあるフック7は、抜止部911が鉤部内側に配置されると共に付勢部材95により移動保持部材93が固定保持部材91の側に付勢される。【選択図】図6
