Abstract

PURPOSE: To increase the spring constant in the radial direction by providing the inverse polarity ring magnet with the back surface contacting the top surface of the fixed side magnet.
CONSTITUTION: The inverse polarity ring magnet 12 of which size and shape are the same with those of the fixed side ring magnet 2 is placed and fixed on the ring magnet 12 so that the back surface of the ring magnet 12 contacts the top surface of the fixed side magnet 2. By thus arranging the fixed side magnet, the radial spring constant can be increased.
