To provide an automatic locking device capable of preventing a dead bolt from projecting to a maximum projection amount and becoming locked in an open door state.SOLUTION: An automatic locking device has a lock state in which a dead bolt 70 is projected to a maximum projection amount Pb and a latch state in which the same is projected to an intermediate projection amount Pa, and is equipped with a trigger mechanism 90 in which a trigger actuation member 91 inside a front plate 62 operates to act on a latch engagement member 85 to release the latch state when the door is closed. When the door is closed, a first permanent magnet M1 provided integrally with the trigger actuation member 91 responds to a second permanent magnet M2 provided inside a strike plate 61, and a magnetic force acting on each other is received to operate the trigger actuation member 91.SELECTED DRAWING: Figure 13
【課題】開扉状態で、デッドボルトが最大突出量まで突出してロック状態となるのを未然に防止することができる自動施錠装置を供する。【解決手段】デッドボルト70が最大突出量Pbまで突出したロック状態と中間突出量Paまで突出したラッチ状態を有し、閉扉したときにフロント板62の内側のトリガー作動部材91が作動してラッチ係止部材85に作用してラッチ状態を解除するトリガー機構90を備えた自動施錠装置において、閉扉したときに、トリガー作動部材91に一体に設けられた第１永久磁石M1がストライク板61の内側に設けられた第２永久磁石M2に対応して互いに作用する磁力を受けてトリガー作動部材91を作動することを特徴とする。【選択図】図１３
