Beschreibung
Zusammenfassung:	A vibration mechanism having a magnetic spring includes a lower frame, an upper frame vertically movably mounted on the lower frame via a plurality of link mechanisms, and at least two permanent magnets mounted on the lower frame and the upper frame, respectively, with the same magnetic poles opposed to each other. A plurality of springs are connected to the link mechanisms to produce a lifting force of the upper frame. The total spring constant of the permanent magnets and the springs is partially set to a negative value or substantially zero.
