Claims

[Scope of utility model registration request]

(1) A holder that is pivotally connected to a link and can be rotated by the link, a shaft groove formed in opposite sides of the holder on both sides of the holder, and a shaft supported by the shaft groove formed on both sides. In a circuit breaker opening/closing device comprising a movable contact block disposed between both side plates of a holder and swingably supported in the plate thickness direction, the shaft formed in the movable contact block is shaped like a substantially semi-cylindrical column. and the width of the insertion opening of the shaft groove formed in the holder into which the shaft is inserted is smaller than the diameter of the shaft and slightly larger than the minimum dimension in the radial direction of the shaft. circuit breaker switchgear.

(2) Utility Model Registration Scope of Claim In the circuit breaker opening/closing device according to claim 1, when the movable contact block is incorporated into the holder, a part of the rear stopper of the movable contact block has a shaft hole that is pivoted to the link of the holder. A switching device for a circuit breaker, characterized in that the opening direction of an insertion opening of a shaft groove provided in a holder so as to cross the holder and the shape of a part of a stopper of a movable contact stand are set.
