Abstract: A rotary sliding device which can perform agile motion, without the need to make the driving means large, and a simulator using the same, are disclosed. The rotary sliding device includes first and second sliding plates 32 which slide in parallel and separately with a predetermined interval, a pair of stepping motors 20 for separately sliding said sliding plates 32, and a moving plate 12 and a seat 32. The first sliding plate 32 is connected to the moving plate 12 so as to allow it to rotate only around the rotation axis 38, and the second sliding plate 32 is connected to the moving plate 12 so as to engage therewith in a sliding direction, and to allow the moving plate 12 to move in the crossover direction to the sliding direction and to rotate by means of a roller 64.
