遮断器の開閉機構。 A cylindrical sheath shaft is attached between the poles of a cross bar that communicates the movable contact assemblies of a contact device in which multiple poles are arranged in parallel and is supported by the pole spacing wall; a side plate having a U-shaped groove that is arranged parallel to the contact device and swingably guides the sheath shaft; and a side plate that is connected between the side plate and the movable contact assembly and is in a closed position when standing up. a toggle mechanism that moves the movable contact assembly to an open position when it collapses, and a toggle mechanism that is pivotally supported on the side plate so that it can be engaged with the toggle mechanism, and is disengaged by swinging due to overcurrent or the like and collapses the toggle mechanism. A latch receiver, a handle lever that is swingably guided by the sheath shaft and has an operating handle fitted into its head, and a joint pin of the toggle mechanism that is stretched between the handle lever and the joint pin of the toggle mechanism. An opening/closing mechanism for a circuit breaker, comprising an opening/closing spring that reverses its action when a point is exceeded.
