ABSTRACT:
A solenoid actuator of high performance comprising a coil surrounded externally with a magnetic frame and having a stationary core disposed therein, with a movable core attracted to the stationary core upon energizing the coil being disposed axially slidably, wherein the magnetic frame comprises a pair of magnetic frame parts each fabricated from a sheet material by bending the sheet so as to define a top plate and a bottom plate integrally joined with a side plate for covering the top, bottom and side of the coil, and the pair of magnetic frame parts are assembled to each other with their top plates and bottom plates being overlapped to each other, to thereby provide simplified structure and easy assembling.
