Abstract
In an electromagnetic switch device, a direction where a first plunger moves at the time a solenoid for pinion extrusion operates and a direction where a second plunger moves at the time a solenoid for motor energization operates are constituted in the same direction. A concave portion having a predetermined depth D is formed in a first fixed iron core used for the solenoid for pinion extrusion and a stopper member that controls a returning position of the second plunger is arranged therein. A part of the second plunger overlaps to the first fixed iron core in the axial direction.
