To provide a motor driving system lifting and lowering type gate door capable of being compactly installed without requiring for any open margin in front and behind and in the horizontal direction on the ground and simply opening and closing with fine controllability by the motor.

The motor driving system lifting and lowering type gate door 1 is constituted by including a driving mechanism making the movement of the rise and fall of the door body 11 carry out and a guiding means making its posture vary between a vertical shut off state and horizontal full admission state by rotating the door body 11 with the movement of the rise and fall of the door body 11. The driving mechanism is constituted by including an electric motor and a chain drive mechanism rotationally driven by the electric motor. It is constituted of a pair of perpendicularly arranged right and left of the first guide rail 9 and a pair of reverse L-shaped right and left of the second guide rail 10 formed by connecting a vertical section 10a and a horizontal section 10b with a round-shape section 10c.
