To raise the adsorbing force of an armature by generating a sufficient magnetic flux at a yoke without interfering with a fastening shaft, related to an electromagnetic actuator in which a plurality of laminates are fastened together with the fastening shaft to constitute a yoke.
Related to an electromagnetic actuator mechanism 62, a yoke 70 where a fastening shaft 75 is inserted in stacked laminates 68 and 69 for integration is provided with coil housing grooves 68a and 69a. A coil 71 housed in the coil housing grooves 68a and 69a is excited so that the yoke 70 generates a magnetic flux for attracting an armature 73. The fastening shaft 75 is disposed on the side of the yoke 70, outside a magnetic path C formed by the yoke 70, so that the yoke 70 generates a sufficient magnetic flux without interfered with the fastening shaft 75, for a raised attracting force of the armature 73.
