To provide an elevator and an elevator evaluation method capable of quantitatively evaluating the airtightness of a car.SOLUTION: The elevator comprises: a car having a cage; a blower; a control unit that controls driving of the blower; and a pressure fluctuation measurement unit that measures fluctuation of atmospheric pressure in the cage and outputs measured information to the control unit. The control unit controls the blower to blow a prescribed amount of air into the cage, and derives a gap in the cage from pressure fluctuation information in the cage before and after driving of the blower.SELECTED DRAWING: Figure 5

    【課題】乗りかごの気密度を定量的に評価することができるエレベーター及びエレベーターの評価方法を提供する。【解決手段】エレベーターは、かご室を有する乗りかごと、送風機と、送風機の駆動を制御する制御部と、かご室の内部の気圧の変動を測定し、測定した情報を制御部に出力する圧力変動情報と、を備えている。そして、制御部は、送風機を制御してかご室に所定の風量の空気を送風し、送風機の駆動前後でのかご室の内部の圧力変動情報からかご室の隙間を導出する。【選択図】図5
