PROBLEM TO BE SOLVED: To stabilize a size of force for extracting a hook.SOLUTION: A locking device of a fire door comprises a latch member (a latch plate 130) for locking a hook 600, a lock member (a lock lever 140) for locking the latch member in a locking state of the hook 600 and releasing a lock by shifting one end part in action time of force for extracting the hook 600, an energization member (a compression coil spring 154) for energizing in the direction for restraining shifting, an energization force adjustment screw (a release force adjustment screw 153) having a male screw part and a noncircular cross-section part and adjusting energization force and a pressing member 156 for pressing the noncircular cross-section part of the energization adjustment screw in the rotational center direction.SELECTED DRAWING: Figure 2
【課題】フックを引き抜く力の大きさを安定させる。【解決手段】防火扉の係止装置は、フック６００を係止するラッチ部材（ラッチ板１３０）と、ラッチ部材をフック６００の係止状態にロックし、フック６００を引き抜く力の作用時に一端部が変移してロックを解除するロック部材（ロックレバー１４０）と、上記変移を抑制する方向に付勢する付勢部材（圧縮コイルばね１５４）と、雄ねじ部と非円形断面部を有し上記付勢力を調整する付勢力調整ねじ（解除力調整ねじ１５３）と、付勢力調整ねじの非円形断面部を回転中心方向に押圧する押圧部材１５６と、を備える。【選択図】図２
