PROBLEM TO BE SOLVED: To suppress displacement in a radial direction of a mover 32, to suppress variation of attraction by a stator 33, and to stabilize the reduction speed of a back pressure, in a solenoid valve 3 of an injector. SOLUTION: The solenoid valve 3 has a spherical body 56 for transmitting force between a coil spring 34 and a mover 32, the spherical body 56 is received by a receiving surface 57 provided on the mover 32 and supported freely slidably in an axial direction by a stator 33, and the receiving surface 57 is provided so as to form a recess to be continuously reduced in diameter toward an energizing direction (distal end side) by the coil spring 34. Thus, by being abutted to the mover 32 through the receiving surface 57, the spherical body 56 exerts abutting force to the mover 32 so as to dissolve the displacement in the radial direction. Thus, in the solenoid valve 3, the displacement in the radial direction of the mover 32 is suppressed, the variation of the attraction by the stator 33 is suppressed, and the reduction speed of the back pressure is stabilized.
