<p>PROBLEM TO BE SOLVED: To provide a locking device incapable of being unlocked even if another magnetic substance is used and to make it impossible to disassemble or unlock the device from the outside thereof. SOLUTION: When a magnetized card key is inserted into an insertion section of an unlocking device, an operation pin 19 inserted into inserting operation holes 26 and 28 formed in an operation hole 20 of a lift 18, an operation piece 25 and a cover piece 27 by magnetic force distributed and inputted to the card key is moved by magnetic force of the card key, and the lift is interlocked with the operation piece. By turning a knob, a cam 30 having an insertion hole 301 inserting an inserting projection 102 of the knob thereinto pushes an uneven step section 23 in a through-hole formed in the central part of the lift while turning it, and a lifting section is guided by guides 14 and 141 formed in a fixed plate 12 and is lowered. An unlocking piece 25a energizing a pressure section 25a formed in the lower end of the operation piece interlocked with the operation pin to an inserting notch section 201 of a joint lever 2 with an elastic member 34 is lowered, and an interlocking projection 33 is inserted in an interlocking section 9 of a turning shaft to transfer the turning of the knob to a lock device.</p> |
