Solenoid actuator

Abstract

A solenoid actuator 1 includes: a coil 3; a first stator 10 and a second stator 20 disposed with an air gap 11 therebetween in an axial direction so as to form a magnetic path 4 around the coil 3; and a mover 50 configured to be movable in the axial direction to a maximum stroke position (X=Xmax) from an original position (X=0) on a radially inner side of the first stator 10 toward the second stator 20 by a magnetic force generated by energizing the coil 3. The mover 50 has an annular projection 100 projecting in the axial direction from a peripheral edge portion of the mover 50. The second stator 20 includes: a second yoke 24; and a second press part 40 made of a magnetic material and disposed on an inner peripheral side of the second yoke 24 so as to at least partially form an annular recess 120 for receiving the annular projection 100 of the mover 50 at the maximum stroke position (X=Xmax).
