Abstract
A bus bar is connected between a battery post and a stud bolt to which an electric power supply wire is connected. An opening is provided in a housing in which an explosive sealing portion is accommodated. Just before the opening, a broken portion of the bus bar is provided. In the broken portion, a recess portion is formed, and this portion of the broken portion is thin. On both sides of the broken portion, a cutout portions are formed. In case of emergency, electric current generates in a trigger wire, and an explosive in the explosive sealing portion is exploded. An explosive force is directed to the opening of the housing, and the broken portion located just before the opening receives the explosive force forward. Due to the foregoing, the recess portion is broken and both broken pieces are bent at the cutout portions and opened being separated from each other. In this way, an electric power supply circuit is shut off.
