Claims

[Scope of utility model registration request]

A vacuum container is formed by closing both ends of the insulating cylinder with metal end plates and creating a high vacuum inside. A fixed electrode rod is airtightly introduced into this vacuum container from one metal end plate, and the other metal end plate is closed. A vacuum interrupter in which a movable electrode rod that can approach and separate from the fixed electrode rod is airtightly introduced from the end plate to the fixed electrode rod via a bellows, and a pair of electrodes that can be moved toward and away from the electrode rods are fixedly attached to each inner end of both electrode rods. In this step, one end of the bellows is radially overlapped and welded to a ring-shaped auxiliary member, the other end of the bellows is joined to a movable electrode rod, and the auxiliary member is attached to the inner surface of the metal end plate on the movable side. A vacuum interrupter characterized by being welded together.
