Abstract
A vehicular power seat slide device includes a lower rail adapted to be fixed to a vehicle body floor, an upper rail slidably mounted on the lower rail for supporting a seat device, a nut member secured to the lower rail, and a screw shaft threadably engaged with the nut member and operatively associated with a gear box. To reduce the bending moment in the screw shaft resulting from a load applied to the upper rail in the vehicle lengthwise direction, a flange is provided on the screw shaft, and a block member is secured to the upper rail between the flange and the gear box, with the block member being mounted with respect to the screw shaft to allow rotation of the screw shaft.
