To provide a latch lock with a child-lock function which can prevent a child lock from interfering with unlocking when forcibly unlocking from the outside with a simple structure.SOLUTION: It is configured as such that between a rotary shaft 70 for interlocking a lever 10 on the indoor side and a display on the outdoor side, and a slider 80 that can be engaged with the rotary shaft 70 for a child lock, at a door locking position of the lever 10 and a locking position of the slider 80, engagement between the rotary shaft 70 and the slider 80 is released when the rotary shaft is pushed in from the outside during emergency unlocking, a clutch is formed with which rotation of the rotary shaft 70 is allowed. When forcibly unlocking from the outdoor side, physical contact between the rotary shaft 70 and the slider 80 is released, and unlocking is performed smoothly.SELECTED DRAWING: Figure 4 【課題】チャイルドロック機能付きの打掛錠について、簡易な構造で、室外側からの強制解錠時にチャイルドロックが解錠の妨げとなるのを防止することである。【解決手段】室内側のレバー１０と室外側の表示体とを連動させるための回転軸７０と、チャイルドロックのために回転軸７０と係合可能なスライダ８０との間に、レバー１０のドア施錠位置かつスライダ８０のロック位置において、非常解錠時に回転軸を室外側から押し込んだときに回転軸７０とスライダ８０との係合が解除され、回転軸７０の回転が許容されるクラッチが形成されている構成とする。室外側からの強制解錠の際に、回転軸７０とスライダ８０との物理的接触が解除され、解錠がスムーズにおこなわれる。【選択図】図４
