In addition, in the above-described embodiment, the mode of magnetization of magnet 8 can properly select according to actual conditions, for example, both The mode of magnetization shown in Fig. 4 can be used, the mode of magnetization shown in Fig. 5 can be also used, certainly, can also use other mode of magnetizations.

In addition, in the above-described embodiment, relative to coil 7, the side Z1 on Z and opposite side Z2 are all provided with a first direction Magnet 8 is put, but is not limited thereto, also can the side Z1 on Z or opposite side Z2 set magnetic in a first direction only with respect to coil 7 Body.

In addition, in the above-described embodiment, a coil 7 is provided only with Z in a first direction, in a first direction on Z Magnet 8 relative with coil 7 side Z1 is provided only with one, in a first direction magnet relative with coil 7 the opposite side Z2 on Z 8 are also provided only with one, but are not limited thereto, and multiple coils 7 are may also set up on Z in a first direction, in a first direction on Z Magnet 8 relative with coil 7 side Z1 may also set up multiple, relative with coil 7 opposite side Z2 in a first direction on Z magnets 8 may also set up it is multiple.

In addition, in the above-described embodiment, multiple coils 7 are arranged with second direction X, are corresponded to therewith, in second party Multiple magnets 8 are arranged with to X, but are not limited thereto, a coil also can be only set on second direction X and corresponded to therewith Magnet.

In addition, in the above-described embodiment, connector 9 has viscoplasticity, but is not limited thereto, connector 9 also can be by Flexible material is formed, for example, connector 9 can be also made up of spring.
