1. A position memory device for a power driven seat of a vehicle comprising:
- a rotatable memory wheel which is connectable to the seat;
means for connecting and disconnecting the memory wheel to and from the seat to convert movement of the seat to rotation of the memory wheel when connection therebetween is established;
means for rotating the memory wheel into a first position when the memory wheel is disconnected from the seat;
memory switch means coupled to the memory wheel, the switch means being set in the OFF condition while the memory wheel is in the first position, and being set in the ON condition while the memory wheel is in a position other than the first position; and
power drive means able to move the seat together with the memory wheel while the switch means are in the ON condition, and being disabled from moving the seat while the switch means are in the OFF condition;
whereby, after the seat is stopped in a desired position and the memory wheel is disconnected from the seat and rotated to the first position, the memory wheel is connected to the seat to thereby memorize the desired position so that the seat may be returned to the memorized position from another position by the power drive means.
