Abstract:
In order to optimize the clearances between both end surfaces of a sleeve 5 and each of the end surfaces of the fixed bodies 3 and 5, respectively, magnetic forces of repulsion being caused by each of the permanent magnets 3a, 5b, 5c and 8a is adjusted. At this time, by adjusting each of the distances between the permanent magnets 3a, 5b, 5c, 8a, respectively, by adjusting the quantity of the adjustment rings 9, the magnetic force of repulsion being caused by each of the permanent magnets 3a, 5b, 5c and 8a is adjusted.
