Provided is a structure for a small-sized, lightweight air slide device in which the travel stability of a slider is high. This air slide device (1) comprises: a rail (2) having slider guide surfaces (211, 212) formed of a magnetic substance; and a slider (3) that moves in the length direction (X) of the rail (2) on the slider guide surfaces (211, 212) of the rail (2) in a non-contact manner. The slider (3) comprises: slide plates (31) combined in the shape of the letter L; and first and second air bearings (4A, 4B) attached to the respective slide plates (31) so as to be positioned between the respective slide plates (31) and the rail (2). Each of the first and second air bearings (4A, 4B) comprises: a magnetic-force generating part (41) that generates a magnetic force; and a compressed-air supplying part (42) that is arranged around the magnetic-force generating part (41) and discharges compressed air. An end surface (421) of the compressed-air supplying part (42) and an end surface (411) of the magnetic-force generating part (41) together constitute a support surface (40) that opposes each slider guide surface (211, 212) of the rail (2) in a non-contact manner. |
