Abstract
A solenoid actuator 1 (1A, 1B) 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 move in the axial direction toward the second stator 20 from an original position radially inward of the first stator 10 by a magnetic force generated by energizing the coil 3. The first stator 10 includes: a first yoke 14; and a first cylindrical member 30 fixed to an inner peripheral side of the first yoke 14 and forming the air gap 11.

A solenoid actuator, comprising:
- a coil;
- a first stator and a second stator disposed with an air gap therebetween in an axial direction so as to form a magnetic path around the coil;
- and
- a mover configured to move in the axial direction toward the second stator from an original position radially inward of the first stator by a magnetic force generated by energizing the coil,
- wherein the first stator includes:
- a first yoke;
- and
- a first cylindrical member fixed to an inner peripheral side of the first yoke and forming the air gap, the first cylindrical member being radially disposed between the mover and the first yoke.
