Claims

[Scope of utility model registration request]

A power seat slide device in which an upper rail that connects to the seat and a lower rail that connects to the vehicle body engage with each other, and a screw shaft that moves the upper rail back and forth along the lower rail via a drive device is housed within the lower rail. A groove is formed in the upper surface of the upper rail in the longitudinal direction thereof, and a roller is rotatably interposed between the bottom surface of the groove and the upper surface of the lower rail,
Stoppers for regulating the rolling of the rollers are provided protruding near both ends and substantially at the center of the upper rail and the lower rail, respectively, and the driving device is disposed between a pair of stoppers projecting from the substantially center of the lower rail. A power seat slide device that is characterized by:
