To provide an automatic locking device capable of preventing a dead bolt from protruding to the maximum protrusion amount which results in a locked state while in a door open state.SOLUTION: In an automatic locking device which includes a dead bolt 20 having a locked state in which the dead bolt protrudes to the maximum protruding amount Pb and a latched state in which the dead bolt protrudes to an intermediate protruding amount and which is equipped with a trigger mechanism 30 that operates upon door closure a latch locking member 35 to cause a trigger operating member 31 inside a front plate 12 to activate thereby releasing the latched state, a configuration is employed in which upon door closure, a first permanent magnet M1 provided integrally with the trigger operating member 31 receives a magnetic force generated between the first permanent magnet and a second permanent magnet M2 provided inside a strike plate 11 to activate the trigger operating member 31.SELECTED DRAWING: Figure 7
【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提供する。【解決手段】デッドボルト２０が最大突出量Ｐｂまで突出したロック状態と中間突出量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１２の内側のトリガー作動部材３１が作動してラッチ係止部材３５に作用してラッチ状態を解除するトリガー機構３０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３１に一体に設けられた第１永久磁石Ｍ１がストライク板１１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３１を作動する構成とした。【選択図】図７
