PROBLEM TO BE SOLVED: To provide a power seat slide device, in which stroke quantity of the seat that moves with a large load can be regulated in a simple constitution, and stroke change to apply to other models can be performed at low cost. SOLUTION: The device is provided with a lower rail 21, an upper rail 22 supported by the lower rail to hold the seat, a lead screw member 23 shaft-supported by the upper rail to extend in the slide direction, a feed nut member 24 disposed on the lower rail, and engaged with the lead screw member, a gear box 51 for rotatably supporting a rotating member installed on the upper rail, and connected to the lead screw member, and a drive unit 25 to transmit rotation drive force to the lead screw member through an output rotation member supported by the gear box. Cut and raised parts 60-63 are provided on a pair of right and left vertical walls 22b of the upper rail at respectively facing positions to the feed nut member. The cut and raised parts on the right and left vertical walls are respectively provided at forward and rearward stroke ends of the upper rail where they abut on the feed nut member.
