PROBLEM TO BE SOLVED: To solve a problem in strainers of a conventional spool control valve that as engagement portions of the strainers disposed on both ends, are mounted on regulation means of sleeves by self rigidity, the engagement portions easily separate from the regulation means when external force acts on the strainers.SOLUTION: As locking claws 63 and 64 of strainers 8 and 9 are locked in locking grooves 33-36 of a sleeve 4 in fitting the strainers 8 and 9 to peripheral grooves 31 and 32 of the sleeve 4, the pair of locking claws 63 and 64 are caught by stepped grooves 41-44 even when the external force acts on the strainer 8, so that the strainers 8 and 9 can be prevented from separating from strainer mounting portions of the sleeve 4 even when the external force acts on the strainers 8 and 9. Further, as operability in assembling the strainers 8 and 9 to the peripheral grooves 31 and 32 of the sleeve 4 can be improved, mass-productivity and productivity of a solenoid valve can be improved. |
