Summary:PURPOSE:To increase the sliding stroke of a plunger without reducing suction force by setting the length of air gaps among each armature and a stator at different values, displacing the suction timing of respective armature and sliding the plunger engaged with each armature at multistages. CONSTITUTION:A plural pair of electromagnetic solenoids consisting of coils, stators and armatures are arranged so that the directions of suction of the armatures are directed in the same direction, the length of air, gaps among the stators and the armatures is set at a plurality of kinds, and a plunger is interlinked with respective armature while the plunger can be slid in the direction opposite to the direction of suction of the armature to the armature having the shortest length of the air gap in the interlinkage. The length delta1 of the air gap between the first armature 41 and the first stator 11, the length delta 2 of the air gap between the second armature 42 and the second stator 12 and the length delta3 of the air gap between the third armature 43 and the third stator 13 are set in the relationship of.
