<p>PROBLEM TO BE SOLVED: To provide a solenoid valve in which foreign matter is prevented from reaching a plunger side.SOLUTION: A lower core constituting a solenoid part of a solenoid valve has an outer core member and an inner core member 70 accommodated in a press-in hole of the outer core member. The inner core member 70 is in a substantially cylindrical shape, and has a large-diameter end part 86, whose diameter is set to a maximum as compared with other regions, at its one end part. The other end part, on the other hand, is a small-diameter end part 90 whose diameter is set to a minimum as compared with other regions. An intermediate-diameter part 88 having a diameter smaller than that of the large-diameter end part 86 and larger than that of the small-diameter end part 90 is arranged between the large-diameter end part 86 and small-diameter end part 90. Further, the inner core member 70 has a first step part 92 formed from the large-diameter end part 86 to the intermediate-diameter part 88 and a second step part 94 formed from the intermediate-diameter part 88 to the small-diameter end part 90 on a side wall thereof. The first step part 92 and second step part 94 are alienated at a predetermined angle.</p> |
