The invention provides an elevator device capable of reducing aerodynamic force noise generating during high-speed operation and prolonging the life of a plasma generation device, comprising an elevator car (14) rising and falling in a hoisting trunk (11); a commutating plate (28a,28b) arranged on the elevator car (14) and for commutating the air flow around the elevator car; a plasma generation device (1) arranged on the commutating plate and for playing the discharge plasma function and generating sheeted air flow along the side surface of the hoisting trunk of the elevator car; a sensor (31) on the elevator car (14) or the hoisting trunk (11) and outputting the distance information between the elevator car (14) and the hoisting trunk (11); a control device (23) for performing the switch control of the plasma generation device (1) based on the distance information output by the sensor (31) and the preset threshold value, wherein the control device makes the plasma generation device acts when the distance information is larger than the threshold value and makes the plasma generation device at sleep state when the distance information is less than the threshold value.
