Claims

[Scope of utility model registration request]

A metal end plate having a through hole in the center is airtightly joined to both ends of a metal cylinder so as to close the opening, and a plurality of folds are provided on the outer circumferential surface of one end side of the through hole of each metal end plate. A vacuum vessel is formed by airtightly inserting the tubes through the other end thereof, and a pair of electrode rods is inserted into the tube to bring the pair of electrodes into contact with and separating them within the vacuum vessel while maintaining the airtightness of the vacuum vessel. A vacuum interrupter that is inserted and inserted so that it can be relatively approached and separated.
