As shown in Figure 8, when permanent magnet assembly 26 is when being rotated counterclockwise 60 ° of direction rotations, the N utmost point the 1st flat thin magnet 45 and the N utmost point the 2nd flat thin magnet 46 further move in the pole pieces 37 of homopolarity (the N utmost point), and the S utmost point the 2nd flat thin magnet 48 crosses a distance piece 35 and starts to move in the pole pieces 36 of opposition side (the S utmost point).Thus, the part of cancelling out each other between the polarity of fixed permanent magnet 41 sides and the polarity of the permanent magnet side of permanent magnet assembly 26 further reduces again, and the absorption affinity at 38,38 places, adsorption section further strengthens.In this case, it is large that the rotation torque that handle 32 bears also becomes gradually, can carry out like a cork handle 32 operations.
As shown in Figure 9, when permanent magnet assembly 26 is when being rotated counterclockwise 180 ° of direction rotations, the N utmost point the 1st flat thin magnet 45 and the N utmost point the 2nd flat thin magnet 46 all move in the pole pieces 37 of homopolarity (the N utmost point), and the S utmost point the 1st flat thin magnet 47 and the S utmost point the 2nd flat thin magnet 48 all move in the pole pieces 36 of opposition side (the S utmost point).Thus, 38,38 places in adsorption section, in the absorption affinity from fixed permanent magnet 41,40 sides, add that magnetic attracting device 20 is completely in opening from the absorption affinity of the N utmost point the 1st flat thin magnet 45 and the N utmost point the 2nd flat thin magnet 46 and the S utmost point the 1st flat thin magnet 47 and the S utmost point the 2nd flat thin magnet 48 sides.Also easily carry out in this case handle 32 operations.In addition, handle 32 falls into groove 50 in this position, and hook portion 43 and handle 32 engagings of stop part 52, thus, can maintain the absorption of magnetic (being adsorbed member) safely.
As mentioned above, in the present embodiment, make another distance piece 34 sides on the N utmost point the 1st flat thin magnet 45 and the N utmost point the 2nd flat thin magnet 46 and the S utmost point the 1st flat thin magnet 47 and the S utmost point the 2nd flat thin magnet 48 deflection magnetic components 42 and configure.And, configure the N utmost point the 1st flat thin magnet 45 and the N utmost point the 2nd flat thin magnet 46 the week of magnetic component 42 upwards staggering each other phase place, in the week of magnetic component 42, upwards stagger each other phase place and configure the S utmost point the 1st flat thin magnet 47 and the S utmost point the 2nd flat thin magnet 48.Thus, moving-magnet is that the N utmost point the 1st flat thin magnet 45 and the N utmost point the 2nd flat thin magnet 46 stagger and cross successively temporally another distance piece 34.Therefore, cross once the situation of another distance piece 34 with moving-magnet simultaneously and compare, can peptizaiton in the repulsion of moving-magnet, can disperse and reduce the rotation torque that handle 32 bears, thereby make lever operatedly to become easy.
In order to remove the absorption (closing magnetic attracting device) to magnetic, make handle 32(permanent magnet assembly 26) to the direction rotation with above-mentioned opposite direction.
In this case, owing to acting on handle 32(permanent magnet assembly 26) power also reduce gradually, therefore, can also suppress handle 32 from opening the rotation sharply turning back to while closing, thereby can avoid the problems such as tong, handle 32 damages.
Like this, under magnetic being adsorbed or remove arbitrary situation of the absorption of magnetic, handle 32 all diminishes because of the difference of the moment of torsion that the angle in when rotation produces, therefore, can make handle 32 operation feel very smooth and easy, excellent.
