Magnet switch and a starter using same

摘要

Disclosed is a starter which prevent a magnetic flux change of field device in a d.c. motor against a magnetic field produced by a battery cable and also prevents contact between the battery cable and the d.c. motor when a vehicle vibrates. In the periphery of a magnet switch cover, a pair of a first fixed contact and a second fixed contact are disposed opposing to a moving contact. The first fixed contact is conducted to a battery connecting terminal which connects to a battery cable. The switch cover covers a opening of the switch casing. A motor cover covers an opening of a motor casing disposed in parallel with a magnet switch. On a mounting surface of the battery cable connecting terminal in the switch cover, a washer protrudes from the back end portion of the motor cover in the axial direction.
