To provide an indoor latch lock that is small and can reduce the operation amount of an operation member.SOLUTION: The indoor latch lock is composed of a latch retaining body 4, a reverse latch 5, a first guide surface 10a, and a second guide 10b. The latch retaining body 4 advances and retracts by means of rotation of an operation member via a cam mechanism, and is biased constantly in a locking direction. The reverse latch 5 has a latch rear surface 5b and a latch sloping surface 5c, and is biased constantly on the latch rear surface side and provided rotatably on an end of the latch retaining body 4. The first guide surface 10a contacts the whole latch rear surface in a locked state, and exposes the rear end of the latch rear surface by retracting slightly. The second guide 10b guides the latch sloping surface.SELECTED DRAWING: Figure 1
【課題】小型で、操作部材の操作量を抑えることができる室内用ラッチ錠を提供すること。【解決手段】 操作部材の回動によりカム機構を介して進退するとともに常時施錠方向に付勢されたラッチ保持体４と、ラッチ背面５ｂとラッチ傾斜面５ｃとを有し常時ラッチ背面側に付勢されて回動可能に前記ラッチ保持体４の端部に設けられた反転ラッチ５と、施錠状態では前記ラッチ背面全体と接し、かつ若干の後退で前記ラッチ背面の後端部を露出させる第一のガイド面１０ａと、前記ラッチ傾斜面を案内する第二のガイド１０ｂとから構成されている。【選択図】図１
