Flat thin magnet 47 and s pole the 2nd flat thin magnet 48 are still located in initial pole pieces 37.Thus, the pole of fixed permanent magnet 41 side
That cancels out each other between property and the polarity of permanent magnet side of permanent magnet groups zoarium 26 partly reduces further, adsorption section 38,
Absorption affinity at 38 strengthens.In this case, because n pole the 1st flat thin magnet 45 and n pole the 2nd flat thin magnet 46 are successively to homopolarity (n pole)
Move in the pole pieces 37 of side, therefore, the rotation torque that handle 32 is born also becomes larger, handle operation is relatively easy to.
As shown in figure 8, when permanent magnet groups zoarium 26 rotates 60 ° to rotate counterclockwise direction, n pole the 1st flat thin magnet 45
Move in the pole pieces 37 of homopolarity (n pole) further with n pole the 2nd flat thin magnet 46, and, s pole the 2nd flat thin magnet 48 crosses one
Individual distance piece 35 and start to move in the pole pieces 36 of opposition side (s pole).Thus, the polarity of fixed permanent magnet 41 side with
The part cancelled out each other between the polarity of permanent magnet side of permanent magnet groups zoarium 26 further reduces, adsorption section 38,38
The absorption affinity at place further enhances.In this case, the rotation torque that handle 32 is born also becomes larger, and can easily enter
Row handle 32 operates.
As shown in figure 9, when permanent magnet groups zoarium 26 rotates 180 ° to rotate counterclockwise direction, n pole the 1st flat thin magnet 45
All move to the pole pieces 37 of homopolarity (n pole) with n pole the 2nd flat thin magnet 46, and, s pole the 1st flat thin magnet 47 and s pole the 2nd
Flat thin magnet 48 all moves to the pole pieces 36 of opposition side (s pole).Thus, at adsorption section 38,38, carrying out self-retaining forever
Magnet 41, the absorption affinity of 40 sides add from n pole the 1st flat thin magnet 45 and n pole the 2nd flat thin magnet 46 and s pole the 1st flat thin magnet 47 long
With the absorption affinity of s pole the 2nd flat thin magnet 48 side, magnetic attracting device 20 is completely in opening.Also handss are easily carried out in this case
Handle 32 operates.In addition, handle 32 falls in groove 50 in this position, and, the hook portion 43 of stop part 52 is locking with handle 32, by
This, can safely maintain the absorption of magnetic (adsorbed component).
As described above, in the present embodiment, n pole the 1st flat thin magnet 45 and n pole the 2nd flat thin magnet 46 and s pole the 1st magnetic are made
Iron plate 47 and s pole the 2nd flat thin magnet 48 are partial to another distance piece 34 side ground configuration on magnetic component 42.And, in magnetic structure
Configure n pole the 1st flat thin magnet 45 and n pole the 2nd flat thin magnet 46, in the week of magnetic component 42 with offseting one from another phase place in the circumference of part 42
Configure to the phase place that offsets one from another upwards s pole the 1st flat thin magnet 47 and s pole the 2nd flat thin magnet 48.Thus, moving-magnet is n pole the 1st magnetic
Iron plate 45 and n pole the 2nd flat thin magnet 46 staggering time ground cross another distance piece 34 successively.Therefore, disposable with moving-magnet
Ground crosses the situation of another distance piece 34 simultaneously and compares, can peptizaiton in the repulsion of moving-magnet, can disperse and subtract
The rotation torque that miniature lever 32 is born, so that handle operation becomes easy.
In order to release the absorption to magnetic (closing magnetic attracting device), make handle 32 (permanent magnet groups zoarium 26) to upper
State direction in opposite direction to rotate.
In this case, because the power acting on handle 32 (permanent magnet groups zoarium 26) is also gradually reduced, it is thus possible to
Enough rotations drastically when unlatching returns to closing for the suppression handle 32 are such that it is able to avoid the problems such as tong, handle 32 damage.
So, magnetic is being adsorbed or is being released under the either case to the absorption of magnetic, handle 32 is because of rotation
When angle and the difference of moment of torsion that produces all diminish, therefore, it is possible to make handle 32 operation feel very smooth, excellent.
