Abstract

PURPOSE:To suppress the free vibration between two magnetic poles, by organizing a shaft, which controls on the same axis the opposing condition of top and bottom magnets which are placed so that the same poles are opposite to each other, by a magnetic body, and then, by allowing the center opening of two yokes to pass through the shaft as a part of the magnetic path. CONSTITUTION:Annular magnets 1 and 11, which are axially magnetized, are placed so that the same poles are mutually opposed to each other, and these magnets are securely attached to the bottoms of ?-shaped yokes 3 and 13 through spacers 2 and 12 made of non-magnetic body. And, sleeves 5 and 15 are securely attached to respective center holes of the magnets 1 and 11 through elastic bodies 4 and 14, and by making the sleeves 5 and 15 pass through a magnetic shaft 21 in such a manner as to be able to freely slide, a part of the magnetic path is provided. And therefore, respectively different poles are induced in the sections where the shaft 21 and the yokes 3 and 13 are opposed to each other, and attractions caused to spaces between them maintain amounts of projection of the shaft from the ?-shaped yokes at a constant value. It is possible, by doing so, suppress free vibration caused between the two magnetic poles.
