PURPOSE: A solenoid valve automatically opens to let oil flow to a master cylinder when the outlet pressure of a hydraulic pump is over a certain value to appropriately adjust the braking pressure of the outlet of the hydraulic pump. CONSTITUTION: A solenoid valve includes a shaft hole(33a), a safety spring(39), a fixed member(40) and a fixed ring(38). The shaft hole(33a) is formed in an armature(33) for one end of a plunger(35) to be inserted into the armature(33) and to move forward and backward. The safety spring(39) is mounted in the shaft hole(33a) to support the one end of the plunger(35) elastically. The fixed member(40) is installed in the shaft hole(33a) to support the safety spring(39). The fixed ring(38) is fixed on one end of the armature(33) for the one end of the plunger(35) inserted into the shaft hole(33a) to be fixed and supported.
