Abstract
A gas circuit breaker includes contact rings formed of an elastically deformable material, a movable contact that moves reciprocally along an axis line direction between a current supply position where the movable contact bridges the contact rings and a current cutoff position where the movable contact is separated from both the contact rings, holding tools formed in an annular shape and respectively attached to the contact rings, a covering member having electrically insulating property, slidably attached to a distal end portion of the holding tool in the axis line direction, and configured to be brought into contact with the contact ring, and a covering member having electrically insulating property, slidably attached to a distal end portion of the holding tool in the axis line direction, and configured to be brought into contact with the contact ring.
