According to the invention, a starter includes a motor and an electromagnetic switch. The electromagnetic switch includes a switch case, a movable contact, a fixed contact, a contact cover, an excitation coil, an excitation coil terminal, a motor terminal, and a protective cover. The excitation coil terminal has a first end, which is located inside the contact cover and electrically connected to the excitation coil, and a second end that protrudes outside the contact cover so as to be electrically connected to a power source. The motor terminal has a first end, which is located inside the contact cover and electrically connected to the fixed contact, and a second end that protrudes outside the contact cover and is electrically connected to the motor. The protective cover covers both the second end of the excitation coil terminal and the second end of the motor terminal, thereby protecting both the second ends.

What is claimed is: 1. A starter comprising: a motor that generates torque, when supplied with electric power, to start an engine; and an electromagnetic switch that controls supply of electric power to the motor, the electromagnetic switch including a switch case, a movable contact, a fixed contact, a contact cover fixed to the switch case and covering the movable and fixed contacts, an excitation coil provided in the switch case, an excitation coil terminal fixed to the contact cover and having first and second ends, the first end being located inside the contact cover and electrically connected to the excitation coil, the second end protruding outside the contact cover so as to be electrically connected to a power source, a motor terminal fixed to the contact cover and having first and second ends, the first end of the motor terminal being located inside the contact cover and electrically connected to the fixed contact, the second end of the motor terminal protruding outside the contact cover and being electrically connected to the motor, and a protective cover that covers both the second end of the excitation coil terminal and the second end of the motor terminal, thereby protecting both the second ends, wherein the protective cover is formed in one piece to have a cup shape, wherein the second end of the motor terminal is connected to the motor via a conducting member that is made up of a metal plate, the protective cover is fixed to the conducting member at more than one place, and the protective cover comprises: a side wall that has an opening through which the conducting member is passed to electrically connect the second end of the motor terminal to the motor; and a plurality of claw portions that are formed on an inside surface of the side wall which defines the opening, the claw portions engaging with the conducting member, thereby fixing the protective cover to the conducting member. 2. The starter as set forth in claim 1, wherein the protective cover is fixed to the contact cover. 3. The starter as set forth in claim 2, wherein the contact cover is fixed to the switch case by means of a plurality of bolts, and the protective cover is fixed to the contact cover also by means of the plurality of bolts. 4. The starter as set forth in claim 3, wherein each of the bolts is made up of a stud bolt to include first and second threaded portions and a head portion interposed between the first and second threaded portions, the contact cover is fixed with the first threaded portions of the bolts, and the protective cover is fixed with the second threaded portions of the bolts. 5. The starter as set forth in claim 2, wherein the protective cover is fixed to the contact cover at more than one place. 6. The starter as set forth in claim 1, wherein the second end of the motor terminal is connected to the motor via a conducting member, and the protective cover covers both the second end of the excitation coil terminal and the second end of the motor terminal without touching the conducting member.
