Abstract
In a starter motor, its electromagnetic switch has a movable contact cooperating with normally open contact member and normally closed contact member, and a part of a stationary contact in the normally closed contact member is formed into a locking piece to prevent the movable contact from contacting the passage formed in the cap of the switch, or the electromagnetic switch has a first movable contact cooperating with normally open contact member and a second movable contact cooperating with normally closed contact member, and an insulating partition wall is disposed between the first and second movable contacts, whereby the creeping distance between the normally open contact member and the normally closed contact member is increased as much, and the occurrence of current leakage is prevented.
