Abstract
A solenoid valve includes: a moving core; a coil for generating magnetic force that attracts the moving core; a stator that forms a magnetic circuit in cooperation with the moving core and attracts the moving core; and a cup-shaped member disposed at the inner periphery of the stator and on the outer periphery of the moving core. The cup-shaped member reciprocatably supports the moving core, and restricts hydraulic fluid leakage from the moving core side to the outer periphery side. A collar made of a soft magnetic material, disposed so as to face a face on the stator side in the axial direction of the moving core, and forming a magnetic circuit in cooperation with the moving core and the stator.
