Abstract
A low friction and stable sliding structure for an electronic device is provided. The sliding structure includes a first sliding member comprising at least one guide portion, a second sliding member including a receiving portion receiving the guide portion so as to slide along the first sliding member, a first magnet portion disposed in the guide portion, such that magnetic poles of the first magnet portion are arranged across a sliding direction, and a second magnet portion disposed in the receiving portion so that a repulsive force can act between the first magnet portion and the second magnet portion.
