PROBLEM TO BE SOLVED: To provide a solenoid valve device for a high-pressure fluid capable of preventing fracture of a guide cylinder filled with the high-pressure fluid.SOLUTION: A fixed core 35 is disposed on an opening 208 of a guide cylinder 20 in which a movable core 30 is reciprocatably accommodated. The fixed core 35 is composed of a large diameter portion 351 fixed in the guide cylinder 20, and a small diameter portion 352 projecting outside in the axial direction of the guide cylinder 20. The small diameter portion 352 is provided with a first thread groove 353 to be screwed with a second thread groove 454 formed on a small diameter portion 453 of a cover portion 45. When the cover portion 45 and the fixed core 35 are screwed, rotating torque for rotating the cover portion 45 acts on the fixed core 35. Thus deformation of a magnetic blocking portion 21 formed with a relatively thin thickness in the guide cylinder 20 can be prevented, when the cover portion 45 is rotated with large rotating torque. Accordingly, fracture of the guide cylinder 20 filled with a gas fuel of high-pressure can be prevented. |
