Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vibration-proof device of gas insulation switch gear which can effectively prevent propagation of vibration to a housing floor slab due to an impact force, when a gas cut-off device operates without deteriorating the vibration-proof characteristic of the gas insulation switch gear. SOLUTION: This vibration-proof device of the gas insulation switch gear is provided with an acceleration sensor 16 for detecting vibration accompanied by opening and closing of the gas breaker 12, installed on a floor slab 1 between the gas breaker 12 of the gas insulation switch gear installed on the floor slab 1 of housing and a pole 15 of the housing nearest to the relevant gas breaker; and a vibration-proof unit 17 which is installed on the housing slab to generate vibration in the inverse direction to the vibration due to the gas breaker with a signal from the acceleration sensor.
