Abstract: A stepped portion is formed in an outer peripheral portion of a slide core and is stepped to reduce an outer diameter of one portion of the slide core located on one axial side of the stepped portion. A first conducting portion of a ring core covers an outer peripheral surface of the one portion of the slide core and is slidable along an outer peripheral surface of the one portion of the slide core. The first conducting portion conducts a magnetic flux between the first conducting portion and the slide core in a radial direction. A second conducting portion of the ring core is configured into a form of a flange and radially outwardly extends from the first conducting portion. The second conducting portion conducts the magnetic flux between the second conducting portion and a bottom wall portion of a yoke in an axial direction.

Abstract: A communication hole is formed in a peripheral wall portion of a yoke. The communication hole communicates between an inside and an outside of the yoke. A gap, which is formed between one end portion of the coil and a bottom wall portion of the yoke, overlaps with the communication hole in an axial direction.
