風装置となる。However, if the voltage between the control power supplies P and N becomes zero due to a lightning strike on the power distribution line that distributes power to the building where this elevator is installed, the B contact 3b of the voltage detection relay 3 will return to its normal state. Since the voltage of the emergency power supply 4 is applied to the strong side terminal of the fan 2, the fan 2 rotates at high speed. Therefore, even in the summer, the passengers inside the car 1 can wait without feeling uncomfortable until the power supply from the power distribution line is restored, and their sense of anxiety can be reduced. As a result, it is possible to prevent abnormal behavior of passengers who cannot bear the feeling of anxiety and forcefully open the car door, resulting in an elevator car ventilation device that can prevent accidents in the unlikely event of an accident.
