PURPOSE:To secure the correct stop position and prevent the load destruction by pivotally supporting one edge of an arm through each vertical shaft onto a driving device for transferring a supporting base and a trolley which can shift along a guide rail and pivotally connecting the other edges of the both arms onto one longitudinal shaft. CONSTITUTION:When the first arm 5 is turned in the direction of arrow A by a driving device 3 for transfer, the second arm 7 is turned in the direction of arrow B through a pivotal shaft 9. Therefore, a trolley 6 shifts in the direction of arrow C. When the first arm 5 turns half, the first and second arms 5 and 7 are superposed, and the longitudinal shafts 4, 8, and 9 are arranged on the vertical plane extending in the longitudinal direction. Then, the first arm 5 is turned half, and the trolley 6 shifts to the front edge position as original position. With such constitution, the transfer speed at the front and rear edge positions of the trolley 6 can be reduced, and the trolley 6 can be slowly started and stopped, and the stop position precision can be improved, and the load destruction can be prevented.
