PURPOSE:To fix a support metal to a vacuum container by forming metal fittings of plural wave parts. CONSTITUTION:An intermediate shield 10 between a vacuum container 1 and electrodes 4, 5, on which shield 10 metal fittings having wave parts 12, 13 which are mounted on the inner face of the vacuum container 1 are mounted. The temperature in the container 1 increases or decreases during the operation of a vacuum circuit breaker or at the time of mounting a support metal 11 on the inner face of the container 1 by brazing, so expansion and contraction of the intermediate shield 10 occur, but this deformation will be absorbed by the wave parts 12, 13. It is therefore possible to tightly fixate the support metal 11 without being dismounted from the container 1. |
