ELECTROMAGNETIC LINEAR SOLENOID

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic linear solenoid comprising an even stroke characteristics by suppressing dispersion in electromagnetic attractive force accompanying movement of a moving piece. SOLUTION: Related to an electromagnetic solenoid comprising a coil 12, a stator 15 of magnetic material provided in the coil 12, a moving piece 15 of magnetic material movably provided in a guide hole 14a of the stator 14, and an elastic body 16 opposing a magnetic attractive force between the stator 14 and the moving piece 15, a reluctance at a part of the stator 14 or the moving piece 15 is changed.
