ABSTRACT:
In a starter, a power supply terminal connected to a solenoid coil of a magnet switch and connectable to a starter external circuit is provided on an end cover. The power supply terminal includes a terminal metal member, a bimetal which interrupts electric conduction between the solenoid coil and the terminal metal member at the time of temperature rise above a predetermined temperature, and a casing contacting a foot part of the terminal metal member and encasing the bimetal therein. The bimetal responds to each of the excessive heating of the terminal metal member and excessive energization current to interrupt the conduction. In case of a single axis-type starter, the power supply terminal is provided on a recess so that the terminal metal member does not extend axially beyond the rear end face of the end cover.
