Abstract:
An electromagnetic valve comprising:a coil for generating a magnetic force when said coil is energized; a coil bobbin made of resin, around which said coil is wound; an annular magnetic member magnetized by the magnetic force generated by said coil; a stator core fitted in an inner circumference of said coil bobbin and magnetized by the magnetic force generated by said coil; a housing made of resin, said housing formed separately from said coil bobbin for holding and fixing said magnetic member at one axial end face of said coil bobbin such that an inner circumference of said magnetic member is exposed, and for holding and fixing said stator core in the inner circumference of said coil bobbin; and a moving core arranged to face one axial end face of said stator core while providing an axial air gap therebetween, said moving core arranged in the inner circumference of said magnetic member while providing a radial side gap therebetween, said moving core attracted toward said stator core by the magnetic force generated by said coil; wherein the moving core directly faces the inner circumference of the magnetic member via the radial side gap.
