Abstract
A solenoid actuatorincludes: a coil; a first statorand a second statordisposed with an air gaptherebetween in an axial direction so as to form a magnetic patharound the coil; and a moverconfigured 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 statortoward the second statorby a magnetic force generated by energizing the coil. The moverhas an annular projectionprojecting in the axial direction from a peripheral edge portion of the mover. The second statorincludes: a second yoke; and a second press partmade of a magnetic material and disposed on an inner peripheral side of the second yokeso as to at least partially form an annular recessfor receiving the annular projectionof the moverat the maximum stroke position (X=Xmax).
