とする無人搬送車。[Claims for Utility Model Registration] (1) A main body frame, a front wheel that is attached to the main body frame and performs driving rotation and steering operations, a loading fork that is connected to the rear of the main body frame so as to be able to rise and fall, and the fork of the fork. In a low-lift conveyance vehicle having a rear wheel that is attached to the lower surface of the rear end side via an elevating mechanism and rotates as a driven vehicle, the vehicle is attached to a member that is located in front of the front wheel and moves with the steering operation of the front wheel, and that is attached to the running floor surface when moving forward. a forward movement sensor that detects a taxiway laid on the running floor; and a forward sensor that is attached to the rear end of the fork at a position rearward of the rear wheels and detects the taxiway laid on the running floor when traveling backwards. a reverse sensor, a steering motor that steers the front wheels, a control device that controls the steering motor according to output signals of the respective sensors so as to travel along the guideway, and controls elevation of the fork. An unmanned guided vehicle characterized by comprising a control device for controlling the vehicle. (2) In the automatic guided vehicle according to claim (1), the control device corrects a change in the output signal of the sensor due to a change in the distance between the reversing sensor and the traveling floor surface as the fork moves up and down. An automatic guided vehicle characterized by comprising a correction means for. (3) The automatic guided vehicle according to claim (1), wherein a steering handle for manual operation is connected to the front wheel, and the control device includes a switch means for switching from unmanned operation to manned operation. An automated guided vehicle.
