Claims

[Scope of utility model registration request]

a fixed member, a floating member that can slide in a predetermined sliding direction with respect to the fixed member, a fixed permanent magnet fixed to the fixed member and extending in the sliding direction, and a small gap between the magnetic poles of the fixed permanent magnet. In the magnetic levitation slide mechanism, the magnetic levitation type slide mechanism includes a levitation-side permanent magnet that faces the levitation-side permanent magnet and has a magnetic pole opposite to the magnetic pole, and is fixed to the levitation member and extends parallel to the fixed-side permanent magnet. Divide either or both of the fixed-side or floating-side permanent magnets into a plurality of pieces along the sliding direction, and create a gap sufficient to interrupt the lines of magnetic force between the end faces of adjacent ones of these divided magnets. A magnetic levitation slide mechanism.
