ABSTRACT:
A simple-structured non-contact-guidable magnetic floating device which has stable restoring forces in vertical and horizontal directions perpendicular to the direction of guiding the moving member. At least one inner magnetic member is formed so that magnetic poles are continuously arranged lengthwise thereof. Two outer magnetic members are disposed on both sides of the inner magnetic member in adjacent but spaced relation thereto and formed so that magnetic poles are continuously arranged in a lengthwise thereof. A non-magnetic coupling member is provided apart from the inner magnetic member, for coupling together the two outer magnetic members. A support is provided for supporting and fixing one of the inner and outer magnetic members. The other of the inner and outer magnetic members is held in a floating state in which it has restoring forces to its center positions in vertical and horizontal directions, by magnetic attractive forces between the inner and outer magnetic members or a combination of their magnetic attractive and repulsive forces, and the other magnetic member can be guided lengthwise thereof in the floating state.
