At this time, the attachment portion is mounted with a high-strength attachment plate 13 to which the object is attached for protection of the fixed magnet 12.

The magnetic force generating unit 20 is configured to be a moving magnet 21 is disposed in a position opposite to the fixed magnet 12. At this time, the moving magnet 21 is disposed to face the polarity different from the fixed magnet 12. In addition, the magnetic force generating unit 20 is installed to be movable in the housing 10 so that the object is detached / attached to the attachment to the fixed magnet 12, the attachment portion.

In particular, the moving magnet 21 of the magnetic force generating unit 20 is a fixed magnet 12, when a plurality of permanent magnets are arranged in a predetermined arrangement on the attachment plate 13, a plurality of permanent magnets to correspond to this On the mounting plate 22 is arranged and arranged in an arrangement corresponding to the permanent magnet arrangement of the fixed magnet 12. Here, the predetermined arrangement may be implemented in a plurality of arrangements, such as a plurality of permanent magnets are arranged while maintaining a constant column and row or a circular arrangement state on the circular attachment plate 13 and the installation plate 22, the device In case of miniaturization, each permanent magnet can be composed of a single body.
