An automatic seat positioning device for a vehicle driver's seat wherein a reversible motor is engaged with one of electromagnetic clutches and rotates so that an associated seat member actuating mechanism moves one of the seat members to a desired position for a specific driver from an initial position upto a maximum movable end. In such an automatic seat positioning device of the construction described above, a seat position detector corresponding to the seat member for detecting that the seat member arrives at a specific position at which the detector is located and a preset control circuit for presetting a counter, which indicates the set position of the seat member by counting the number of rotations of the motor, to a value corresponding to the number of rotations of the motor by which the seat member is moved from an initial starting position to the specific position are provided so that an indication error of the counter can be canceled due to slips which occur whenever the motor is repetitively started and stopped, engaged with the electromagnetic clutch. In addition, the automatic seat positioning device stores the positional data of the seat member set at the desired pos…
