PURPOSE: An auxiliary trolley is provided to increase the convenience and to prevent the rattle by moving the trolley through the driving force of a conveyor and returning through the driving force of an air motor. CONSTITUTION: An auxiliary trolley(100) for an automated operation comprises a frame(10), a pillow member(20), a shaft(30), first and second roller members(40,50), a driving device(60), a synchronizing clamp(70) and a control unit(80). The frame is located in one side of a conveyor(31). The pillow member is installed under the frame. The shaft is supported in the pillow member. The first and the second roller members are installed in both ends of the shaft. The driving device drives the shaft. The synchronizing clamp is installed in the one side of the conveyor. The control unit controls the driving device and the synchronizing clamp. Thereby, the auxiliary trolley is moved forward with the conveyor without driving force. Moreover, the trolley is returned by driving an air motor without the rattle.
