PROBLEM TO BE SOLVED: To provide a solenoid valve device that can suppress failure of a valve member or breakage of a movable core, and can increasing a pulling-out load from the valve member of the movable core.SOLUTION: An end 182 of a needle 178 has a tightening face 186 and a stepped face 190 in an order from an end face 184 toward an end 180 side. A base end part 164 of a caulking part 163 of a movable core 158 is formed thinner than a tip 165, and the tip 165 of the caulking part 163 is caulked in a radially inward direction to closely contact the stepped face 190 of the needle 178. The movable core 158 axially holds the end 182 of the needle 178 by an end face abutting part 161 and the tip 165 of the caulking part 163. By this, abrasion dust is not produced by loosening as in fixing the movable core to the needle, and high pressing force is not repeatedly applied to the movable core. Spring back in a radial outward direction of the tip 165 after caulking can be suppressed. |
