PROBLEM TO BE SOLVED: To provide an elevator which achieves automatic opening/closing of an emergency ventilation port provided at a car with small power consumption.SOLUTION: An elevator includes an opening/closing device 2 for opening/closing a ventilation port A provided at a car 10 by an opening/closing member 23. The opening/closing device includes an opening/closing mechanism 20 and a control mechanism 3. The opening/closing mechanism includes: a shaft 216 connected to the opening/closing member; and a self-hold type solenoid 21 including a first electromagnetic coil 211 and a second electromagnetic coil 212 provided together along an axial direction on the inside of a hollow cylindrical magnetic yoke 214, a permanent magnet 213 disposed between the first electromagnetic coil and the second electromagnetic coil, and a plunger 215 movable along a shaft center of the magnetic yoke and connected to a shaft. The control mechanism includes: power storage means 36 for charging power with the start of power feeding from a power supply as a trigger; and a control circuit 30 for flowing a current for predetermined time in the first electromagnetic coil, and for supplying a current to the second electromagnetic coil from the power storage means, with the stop of power feeding from the power supply as a trigger.SELECTED DRAWING: Figure 2

    【課題】かごに設けられた非常用換気口の自動開閉を少ない消費電力で実現するエレベーターを提供する。【解決手段】かご10に設けられた換気口Aを開閉部材23により開閉する開閉装置2を具えたエレベーターであって、開閉装置は、開閉機構20と制御機構3を具え、開閉機構は、開閉部材に接続されるシャフト216と、中空円筒状の磁気ヨーク214の内側に軸方向に沿って併設された第1の電磁コイル211及び第2の電磁コイル213と、第1の電磁コイルと第2の電磁コイルとの間に配設された永久磁石215と、磁気ヨークの軸心に沿って移動可能でありシャフトに連繋されたプランジャー215と、を具える自己保持型ソレノイド21と、を有し、制御機構は、電源からの給電開始を契機として充電する蓄電手段36と、第1の電磁コイルに所定時間電流を流し、電源からの給電停止を契機として、蓄電手段から第2の電磁コイルに電流を供給する制御回路30と、を具える。【選択図】図2
