To provide a hook lock for a sliding door which prevents unlocking even when external force in the unlocking direction is applied to a sickle-shaped hook without using an operation member such as a thumb turn in the locked state in a way without requiring a receiving tool for exclusive use or increasing the number of components.SOLUTION: A hook lock for a sliding door has locking means comprising a locking part 60 formed in a box-shaped case 10 embedded in a sliding door 100 and a locked part 70 formed at a link member 50, and the locking means blocks a rotation of a hook 20 when external force in the unlocking direction is applied thereto by restricting a movement of the link member 50 by the locking of the locking part 60 and the locked part 70 in the locked state, and the locking of the locking part 60 and the locked part 70 is unlocked when a thumb turn hub 30 is rotated in the unlocking direction.SELECTED DRAWING: Figure 1
【課題】専用の受け具を要したり部品点数を増やしたりしない方法で、施錠状態時に、サムターンなどの操作部材を用いることなく鎌形の鈎具に解錠方向への外力が加えられても解錠してしまうことのない引戸用鎌錠を提供する。【解決手段】引戸１００に埋め込まれた箱型のケース１０内に形成された係止部６０とリンク部材５０に形成された被係止部７０とからなる係止手段を有し、前記係止手段は、施錠状態において前記係止部６０と前記被係止部７０との係止により前記リンク部材５０の運動を規制することで、鈎具２０に解錠方向の外力が加わった際の回転を阻止するとともに、サムターンハブ３０を解錠方向へ回転させた際に前記係止部６０と前記被係止部７０との係止が解除される。【選択図】図１
