PROBLEM TO BE SOLVED: To provide a latch lock of a simple configuration capable of releasing regulation on an inversion latch by operating an operation member, and actuating an inside/outside air pressure difference canceling device while stably maintaining the released state.SOLUTION: A lock box has the following components provided therein: a latch regulating member 54 for regulating an inversion latch 50; a drive cam 12 rotated by a predetermined amount by operation force of an operation member; an operation piece 46 for canceling regulation on the inversion latch, interposed between the drive cam and the latch regulating member; and an inside/outside air pressure difference canceling device that includes a sliding control body 24 slid toward a front side by driving force of the drive cam, and a swinging pressing body 27 rotated in a horizontal direction by the sliding control body. The drive cam includes: a first engaging part 13 engaging with the operation piece and extending outward in a radial direction; a second engaging part 14 engaging with the sliding control body and extending outward in the radial direction; and a cam part 48 on a top surface on a side of the operation piece. An inclined surface 48a and a horizontal support surface 48b continuing from the inclined surface are formed on the cam part, the inclined surface canceling the regulation on the inversion latch and the horizontal support surface maintaining the canceled state of the regulation by the latch regulating member.SELECTED DRAWING: Figure 2
【課題】簡単な構成で、操作部材の操作により反転ラッチの規制を解き、規制解除状態を安定的に維持したまま内外気圧差解消装置を作動させるラッチ錠を提供する。【解決手段】錠箱に反転ラッチ５０を規制するラッチ規制部材５４と、操作部材の操作力により所定量回転する駆動カム１２と、駆動カムとラッチ規制部材の間に介在する反転ラッチ規制解除用の作動片４６とを設け、駆動カムの駆動力によりフロント側に摺動する摺動制御体２４と、摺動制御体により水平方向に回転するスイング式押圧体２７とを備えた内外気圧差解消装置を設けた。駆動カムは作動片と係合する半径外方向の第１係合部１３と摺動制御体に係合する半径外方向の第２係合部１４とを有し、作動片の一側上面にカム部分４８を有し、カム部分には反転ラッチ規制解除用の傾斜面４８ａと傾斜面に続くと共にラッチ規制部材の規制を解除した状態を維持する水平支持面４８ｂとが形成されている。【選択図】図２
