<p>PROBLEM TO BE SOLVED: To provide a solenoid valve that has excellent hysteresis characteristics by securing the coaxiality between a core and a guide collar.SOLUTION: A solenoid part 14 which constitutes a solenoid valve 10 and is accommodated in a housing 12 has a lower core 56, an upper core 58, and a guide collar 78. The lower core 56 therein comprises an outer core member 68 having a press-in hole 76 formed and an inner core member 70 accommodated in the press-in hole 76. The inner core member 70 has a small-diameter end part 90 pressed in the guide collar 78 and also has a large-diameter end part 86, exposed from the guide collar 78, pressed in the press-in hole 76. The guide collar 78 has an opening end part inserted into the press-in hole 76, and a plunger 60 is inserted into it in a displaceable state. Further, the upper core 58 is mounted to cover the other closed end of the guide collar 78.</p> |
