Abstract

PURPOSE:To prevent generation of destruction of magnetic record of magmetic card, etc., and to enlarge magnetic attaching force of an engaging tool by a method wherein constituting magnetic field at a magnet is made to be concentrated at a magnetic pole face to engage with another locking tool having ferromagnetic plate. CONSTITUTION:An opening 1a is provided in the permanent magnet 1 penetrating from one side magnetic pole end face toward the other side magnetic pole end face. A ferromagnetic plate 2 is affixed to one side magnetic pole face of the magnet 1, a ferromagnetic plate 3 having an opening 3a to be connected to the opening 1a is affixed to the other side magnetic pole face, and the ferromagnetic plates 2, 3 are fixed in one body with cases 4. A ferromagnetic rod 6 is disposed in upright in the opening 1a of the magnet 1 interposing a magnetic gap between them, and a hole 3a of the ferromagnetic plate 3 is provided positioning as to surround the top part of the rod 6 to make magnetic flux at the top end part of the rod 6 to be concentrated to enlarge magnetic attaching force with a plate 5.
