Abstract

To provide an opening/closing device of a switch gear capable of improving efficiency of opening/closing operations by reducing the number of rotary connection parts in a link mechanism. In this switch gear opening/closing device, a movable contact 5 can be switched to the first position Y1, the second position Y2 and the third position Y3 with respect to a fixed contact. The device comprises: an operation lever 80 interlocked with the movable contact 5; a shaft 31 to which the base part of the operation lever 80 is fixed; a first operation mechanism 40, coupled with the shaft 31, to switch-operate the movable contact 5 to the first position, the second position and the third position; and a second operation mechanism 70 to selectively switch between prevention of movement and movement of the movable contact 5 from the second position to the third position by the first operation mechanism 40.
