Abstract
An opening/closing device of an embodiment has first to third movable contacts, first to third transmission mechanisms, first to third containers, a crankshaft, an operating mechanism, and a shock absorbing mechanism. The first to third movable contacts are accommodated in the first to third containers. The first to third transmission mechanisms are connected to the first to third movable contacts. The first to third containers accommodate at least the first movable contact. The crankshaft operates the first to third transmission mechanisms and changes the first to third movable contacts from a closed state to an open state. The operating mechanism is disposed on the side of the first transmission mechanism to rotate the crankshaft. The shock absorbing mechanism is disposed on the side of the third transmission mechanism to absorb a shock of rotational movement of the crankshaft.
