を特徴とする真空バルブ。 An end plate that seals both ends of the insulating cylinder, and an end plate that passes through one of these end plates, advances and retreats in the axial direction, and passes through the other end plate in an airtight manner to approach and separate from a fixed contact fixed to the end plate. a movable contact comprising an electrode at the tip of a current-carrying rod, and peripheral edges of both ends in the axial direction are hermetically joined to the movable contact and the opening side of the one end plate through which the contact passes, respectively. In a vacuum valve equipped with a metal bellows that enables a movable contact to advance and retreat in the axial direction while maintaining a vacuum in an insulating cylinder, a layer of a stretchable synthetic resin is coated to a certain thickness on the atmosphere side surface of the metal bellows. A vacuum valve characterized by being formed with a diameter larger than 1.
