Abstract
A solenoid includes a coil portion, a yoke having a cylindrical portion and a bottom portion and accommodating the coil portion, a plunger configured to slide in an axial direction, a stator core. The stator core has a magnetic attraction core, and a sliding core having a cylindrical core portion, a first magnetic flux transfer portion configured to transfer a flux between the yoke and the core portion, and a magnetic flux passage suppressing portion configured to suppress passage of magnetic flux between the sliding core and the magnetic attraction core. A second magnetic flux transfer portion is arranged on a radial outside of the magnetic attraction core end portion and transfers the magnetic flux between the magnetic attraction core and the cylindrical portion. The first magnetic flux transfer portion is gap-fitted in the cylindrical portion.
