To provide a hook with a latch, which enables simplification of a hooking operation of a wire rope in the hook.SOLUTION: This hook with a latch comprises: a hook body 2 having a base 22 and a tip 23; a main latch 3 pivotally supported at one end on the base 22 and rotatable from a position of abutting at the other end against the inside of the tip 23 to close an opening 24 to a position of being separated inward from the hook body 2 to open the opening 24; a sub-latch 4 pivotally supported on the main latch 3, extending at one end toward the base 22, brought into contact at the other end with the outside or the top of the tip 23, and set at a position of abutting at one end against an inner part 22b of the base 22 and being separated at the other end from the outside of the tip 23; and biasing means 5 for biasing the sub-latch 4 to bias the main latch 3 in a direction to set the closing position. The sub-latch 4 rotates along rotation of the main latch 3. and the sub-latch 4 slides at one end inward along the base 22, and moves away at the other end from the outside of the tip 23.SELECTED DRAWING: Figure 1A
【課題】ワイヤロープをフックに引っ掛ける動作を簡素化した外れ止め付きフックを提供する。【解決手段】基部22と先端部23とを有するフック本体2と、一端が基部22に枢支され、他端が先端部23の内側に当接して開口部24を閉塞する位置から、フック本体2の内方へ離間して開口部24を開放する位置までの間で回動可能なメインラッチ3と、メインラッチ3に枢支され、一端が基部22へ向けて延設され他端が先端部23の外側または頂点に当接し、開放位置であるとき、一端が基部22の内側部22bに当接して他端が先端部23の外側から離間した位置にあるサブラッチ4と、サブラッチ4を付勢することでメインラッチ3を閉塞位置となる方向に付勢する付勢手段5と、を備える外れ止め付きフックは、メインラッチ3が回動するのに伴ってサブラッチ4も回動し、サブラッチ4の一端が基部22に沿って内方へ摺動しながら他端が先端部23の外側から離間する。【選択図】図1A
