Zusammenfassung:PROBLEM TO BE SOLVED: To provide a handling device for a vacuum valve capable of preventing generation of chattering of a movable contact when a pole of the vacuum valve is closed.SOLUTION: In a handling device for a vacuum valve including: a drive lever 204 which is rotatably supported at a frame 4, and rotates by coupling one end to a movable rod 106 which operates the vacuum valve 1 via a pin 206, and driving the other end by a cam mechanism 213 to deviate the movable rod 106 of the vacuum valve 1; and a pressurization spring 207 which energizes the movable rod to the side for closing the vacuum valve on one end side of the drive lever 204, a spring 5 for controlling pole closing speed which energizes a part between one end and a supporting point of the drive lever 204 in the direction opposite to the direction of spring force which acts from the pressurization spring to the drive lever is provided, and pole closing speed of the vacuum valve 1 is adjusted by adjusting the spring force of the spring 5 for controlling the pole closing speed.
