Abstract:
1. A levitation type supporting unit, which is interposed between an object to be supported and an installing surface so as to support the object respective to the installing surface, comprising: a lower magnet part having a lower magnet; an upper magnet part having an upper magnet, arranged at an upper part of the lower magnet part while having an interval in such a manner that the upper magnet part is spaced from the lower magnet part, the upper magnet has a surface facing the lower magnet, a polarity of the surface being equal to a polarity of a corresponding surface of the lower magnet; and a fixing part which includes an upper fixing cap being assembled with the upper magnet part so as to allow the upper magnet part to ascend and descend, a lower fixing cap which is spaced from the upper fixing cap and is assembled with the lower magnet part, and a connecting part formed between the upper fixing cap and the lower fixing cap, the connecting part connecting the upper fixing cap and the lower fixing cap in such a manner that a space formed between the lower magnet part and the upper magnet part is exposed, the fixing part preventing the upper magnet part from escaping from an upper position of the lower magnet part, wherein the lower magnet part includes a lower casing receiving the lower magnet, and the upper magnet part includes an upper casing receiving the upper magnet, and the upper fixing cap includes an upper receiving part receiving the upper casing, the upper receiving part having an opened upper side; a locking jaw being included at an upper part of the upper receiving part so as to prevent the upper magnet part from escaping toward an upper direction; and outer peripheral protuberances formed at an outer circumferential surface of the upper casing, the outer peripheral protuberances being locked with the locking jaw.
