PROBLEM TO BE SOLVED: To suppress a rise of a temperature of a lock solenoid which is arranged at a ventilation device of an elevator.SOLUTION: An elevator having a function for controlling atmospheric pressure in a car chamber comprises: a ventilation window opening/closing member which is arranged so as to be opened and closed for the ventilation of the car chamber; a stopper for setting a position in which the ventilation window opening/closing member closes a door; a lock shaft for locking the door-closed ventilation window opening/closing member; a lock solenoid for operating the lock shaft; a non-lock elastic body for making the lock shaft of the lock solenoid retreat at the interruption of power; and a solenoid cover for covering the lock solenoid. The elevator also has an air flow-in port for supplying air in the car chamber in order to cool the lock solenoid. The solenoid cover has an air flow-out port for discharging air from the air flow-in port, and a valve for opening and closing the air flow-out port.SELECTED DRAWING: Figure 3
【課題】エレベータの換気装置に設けたロック用ソレノイドの温度上昇を抑制する。【解決手段】乗りかご室の内部の気圧を制御する機能を有するエレベータであって、乗りかご室の換気のために開閉可能に設けられた換気窓開閉部材と、換気窓開閉部材が閉扉する位置を設定するストッパーと、閉扉した換気窓開閉部材をロックするロック軸と、ロック軸を動作するロック用ソレノイドと、断電時にロック用ソレノイドのロック軸を後退させる非ロック用弾性体と、ロック用ソレノイドを覆うソレノイドカバーと、を備え、ロック用ソレノイドを冷却するために乗りかご室の内部の空気を供給する空気流入口を有し、ソレノイドカバーは、空気流入口からの空気を排出する空気流出口と、空気流出口の開閉をする弁と、を有する。【選択図】図3
