PURPOSE: A gap zero driving system is provided to prevent safety accidents due to a height difference by inclining a gap zero when the heights of a platform and the threshold of an entrance of an electric vehicle are different. CONSTITUTION: A gap zero driving system comprises a base(400), a driving motor(201), a coupling part(202), a screw(203), an electromagnetic clutch(210), a cross operating rod(208), a coupling member(211), an operating rod(150), and an operating rod guide(206). The base is installed under an extended end of a platform. The driving motor is installed in the base. The coupling part couples the screw to a shaft of the driving motor. The screw is rotated by being interlocked with the coupling part. The electromagnetic clutch couples and interlocks the screw with the operating rod guide. The cross operating rod is coupled to or released from the electromagnetic clutch. The coupling member is coupled to the cross operating rod to be a single body. The operating rod is coupled to the coupling member. The operating rod guide slides the operating rod forwards and backwards.
