Abstract

A solenoid actuatorincludes: a coil; a first statorthat includes a first yokeand a cylindrical guidefixed to an inner peripheral side of the first yoke; a second statorarranged to face the first statorin an axial direction so as to form a magnetic patharound the coiltogether with the first stator; and a moverconfigured to move in the axial direction toward the second statorfrom an original position radially inward of the first statorby a magnetic force generated by energizing the coil. The cylindrical guideincludes: a magnetic tubedisposed in contact with an inner peripheral surface of the first yoke; and a non-magnetic layercovering an inner peripheral surface of the magnetic tube. A minimum distance dbetween the second statorand the magnetic tubeis greater than a minimum distance dbetween the second statorand the moverat the original position.
