A sliding and swiveling device includes a mounting plate, a moving seat, a moving assembly, and a rotating assembly. On the moving scat is provided an inner annular-toothed portion. The rotating assembly includes a fixedly toothed sleeve, a movably toothed ring, a first protruding strip, a camshaft, etc. In the toothed sleeve is provided an annular-toothed portion. On the toothed ring is provided an annular-toothed portion, and the upper surface thereof is provided a protruding pillar. The first protruding strip and camshaft are fitted on the mounting plate, which can be engaged each other or not. The mounting plate can freely rotate in twenty locking positions within 360 degrees around the toothed sleeve. Because the camshaft is also positioned on the mounting plate, the sliding and turning of the chair are both operated in the same place along with the movement thereof, thus it's convenient for users.
