To provide a power seat slide device having improved effects of reducing abnormal sound, a temperature increase, and so on in gear mechanisms and so on. Gear mechanisms each include a case in which a worm and a worm wheel are rotatably supported, the cases are suspended from and supported by upper rails. The worms are connected to and supported by a rotational force transmission shaft of a drive mechanism, and the worm wheels are screwed to and supported by slide screws provided in lower rails. Further, the cases are supported on the lower rails via balls which are rolling members. This structure stabilizes a slide operation of the cases themselves and can further improve the effects of reducing abnormal sound and so on.
