Claims (1)

[Claims for Utility Model Registration] (1) It has an iron core around which a coil is wound, one end of this iron core serves as a magnetic pole part, a yoke is provided at the other end of the iron core, and this yoke extends opposite to the iron core. , an electromagnetic block with the tip of this yoke as a magnetic pole part facing the core magnetic pole part, and a permanent magnet sandwiched between the middle part of each side of the two magnetic pieces from both ends in the direction of magnetization, and each magnetic piece is and an armature block which extends oppositely and whose opposite ends serve as opposed magnetic pole parts, the armature block being disposed at an end in the axial direction of the coil, and having a core magnetic pole part and a yoke magnetic pole part. Both blocks are combined so that they face one set and the other of the two sets of opposing magnetic pole parts of the armature block, and the armature block is perpendicular to the plane containing the iron core and yoke due to the action of the coil and permanent magnet. An electromagnetic device that is designed to move forward and backward within a plane. (2) The thickness of the magnetic pole portion of the iron core in the direction sandwiched between the opposing magnetic pole portions of the armature block is relatively thinner than the thickness of the magnetic pole portion of the yoke in the same direction. Electromagnetic device as described in section. (3) The electromagnet according to claim 1 or 2 of the utility model registration claim, wherein one set of opposing magnetic pole parts of the armature block has a relatively narrower interval than the other set of opposing magnetic pole parts. Device. (4) The electromagnet device according to claim 3, wherein each of the magnetic pole parts constituting a pair of opposing magnetic pole parts is bent inward, so that the interval between the opposing magnetic pole parts is relatively narrow. (5) The electromagnet according to claim 3 of the utility model registration claim, in which one of the magnetic pole portions forming a pair of opposing magnetic pole portions is bent inward, so that the spacing between the opposing magnetic pole portions is relatively narrow. Device. (6) The electromagnet device according to claim 5, wherein the two magnetic pieces are arranged in a V-shape so that the distance between the opposing magnetic poles is relatively narrow.
