Patent ID: 8019397

Claim:
A magnetic levitation sliding structure comprising: a first slide member; a first magnetic portion which is disposed in the first slide member to extend along the lengthwise direction of the first slide member and has magnetic poles arranged perpendicular to the lengthwise direction of the first slide member, wherein the lengthwise direction of the first slide member is an extending direction; a second slide member slidingly engaged with the first slide member; and a second magnetic portion which is disposed in the second slide member to extend substantially parallel to the first magnetic portion and has magnetic poles with opposite magnetic polarity to those of the first magnetic portion in order for the first and second magnetic portions to repel each other, wherein the second magnetic portion is formed to have a shape corresponding to that of a side surface of the first magnetic portion so as to correspondingly enclose at least a portion of the side surface of the first magnetic portion that is partially disposed in the first slide member, thereby being slidingly engaged with the first magnetic portion, and wherein a cross-section of the first magnetic portion has a substantially circular shape, and wherein an internal surface of the second magnetic portion has a substantially semi-cylinder shape corresponding to the side surface of the first magnetic portion.
