Abstract
This breaker device includes: a casing; an igniter configured to generate gas; a pusher located inside the casing and positioned below the igniter; a conductor including a separating portion positioned below the pusher; and an elastic member disposed to be positioned between the casing and the pusher to press the outer side surface of the pusher. In the state where the pusher is stationary after the pusher moves the separating portion downward under the pressure of the gas generated by the igniter, the pusher is located at a level below the elastic member, and the inner surface of the elastic member overlaps the pusher as viewed from above.
