する電磁作動装置。[Claims for Utility Model Registration] A fixed core and a movable core are disposed in series with each other in the axial direction, and one of the mutually opposing surfaces of the fixed core and the movable core is made of a non-magnetic material. A plate-shaped magnetic killer is provided, one surface of the opposing core is provided with a spring accommodating recess in which one end of the return spring is accommodated, and the other end of the return spring is provided on the surface of the other core. In the electromagnetic actuating device that is fitted onto a cylindrical projection, a reduced diameter portion having a predetermined length is formed at the root of the cylindrical projection of the core, and the magnetic killer has a circular hole at the center thereof. It has an annular shape, the thickness of which occupies a majority of the length of the reduced diameter part of the protrusion of the core, and its outer diameter is greater than or equal to the outer diameter of the facing end surface of the core, and the diameter of the circular hole is An electromagnetic actuating device characterized in that the diameter is substantially equal to or slightly smaller than the maximum diameter of the projection, and slightly larger than the diameter of the reduced diameter portion of the projection.
