ABSTRACT:
In a starter, the pinion, which is rotated by torque of an electric motor, is slid axially by the plunger of an electromagnetic switch and is pushed against the engine ring gear by a conically coiled compression coil, which allows employment of a small electromagnetic switch. Further, in an electromagnetic switch in which the plunger confronted coaxially with the stationary iron core slidably supporting a rod with a movable contact is moved towards the stationary iron core by electromagnetic force, a conically coiled spring is interposed between the plunger and the stationary iron core in such a manner that the spring is substantially coaxial with the plunger and the iron core, so that the playing of the rod is prevented.
