A movement device for a vehicle seat includes lower rails extending in a forward or rearward direction of a vehicle are arranged in a vehicle width direction on a vehicle floor. An upper rail provided at a lower part of a seat slidably movably engages with the lower rails. A recess is formed in the vehicle floor, enabling a carriage to be conveyed between the lower rails along the vehicle width direction. The carriage is separated from the vehicle floor, and guide rails are installed on the carriage. The guide rails are provided in extensions of the lower rails so as to be capable of directly accepting a sliding movement of the upper rail from the lower rails, as the upper rail is removed from the lower rail into the extension thereof.
