Abstract
In order to neatly locate an electric drive mechanism under a seat, a unique measure is applied to a power seat slide device. An upper rail has an upper vertical flange through which the seat is secured to the upper rail. The vertical upper flange has a part mounting portion which extends forward beyond a front end of the upper rail. A recess is formed in the part mounting portion, which faces downward. A speed reduction gear box is neatly received in the recess and secured to the part mounting portion through a locking pin. An electric motor has one end secured to the gear box and the other end projected in a direction perpendicular to a direction in which the upper rail runs. A screw shaft extends from the gear box and extends in and along the upper rail. A nut member is secured to the lower rail and operatively engaged with the screw shaft.
