ABSTRACT:
Between a relay terminal of a direct current motor and a contact terminal of an electromagnetic switch, there is provided a fuse which is melted to cut off an electric current upon reaching a predetermined temperature. By properly setting the predetermined temperature at which the fuse melts, it is possible to make the fuse heated to a high temperature and melted in a relatively short time to cut off the electric current in the event of, for example, a continuous operative condition caused due to such a failure as fusion adhesion of a movable contact point with a B-terminal and an M-terminal or fusion adhesion of a contact point mechanism outside a starter, or an overcurrent supply condition caused upon a rotor being locked.
