PROBLEM TO BE SOLVED: To provide a hook holding structure capable of surely fixing a hook.SOLUTION: A hydraulic shovel comprises a rotation link 71, a hook 8, and a hook holding member 91. The hook 8 is rotatably attached to the rotation link 71 with a position PS1 which is at a connection side of the bucket and rotation link 71 as a shaft, and moves between inside and outside of the rotation link 71. The hook holding member 91 is arranged on a position PS2 on a tip end side of the bucket cylinder relative to the position PS1, and is rotatably attached to the rotation link 71 with a shaft parallel to the rotation shaft of the hook 8 as a support shaft. The hook holding member 91 has an insertion member (loose fit member) 910, and in a state in which the hook holding member 91 holds the hook 8, the insertion member 910 contacts a hook part when the hook 8 moves from inside to outside of the rotation link 71, rotation of the hook 8 is thus regulated.SELECTED DRAWING: Figure 5

    【課題】フックをより確実に固定することが可能なフック保持構造の提供。【解決手段】油圧ショベルは、回動リンク71とフック8とフック保持部材91とを備える。フック8は、バケットと回動リンク71との接続側にある位置PS1を軸として回動リンク71に回動可能に取り付けられ、回動リンク71の内側と外側との間を移動する。フック保持部材91は、位置PS1よりもバケットシリンダの先端側にある位置PS2に配置されフック8の回動軸と平行な軸を支軸として回動リンク71に回動可能に取り付けられる。また、フック保持部材91は、挿通部材(遊嵌部材)910を有し、フック保持部材91がフック8を保持する状態において、フック8が回動リンク71の内側から外側に移動する際に挿通部材910が鉤部に当接することで、フック8の回動を規制する。【選択図】図5
