Starter with overheat protection device

摘要

A starter capable of reliably and safely cutting off or breaking a motor circuit when the motor circuit is subjected to an excessively large thermal load is disclosed. The motor circuit includes an intermediate member made of metal and electrically connected between a motor lead wire and a positive-side brush lead wire. The intermediate member has a fuse function that undergoes melting to cutoff the motor circuit when a thermal load excessively larger than that in normal use occurs in the motor circuit.
