PURPOSE: To omit a protective cable, and to cut space thereby by holding a Y-shaped link whose end is pin-connected to a synchronous bar, through a running bar, so as to rotate freely, and by arranging a fixed cylinder on the end of a fork on the base end side of the Y-shaped link.

CONSTITUTION: A piston rod 23a of a cylinder 23 is lowered by changing over two electromagnetic change over valves 33, 34, and a piston rod 24a of a cylinder 24 is lifted, whereby one side of the base end of a Y-shaped link 17 is pushed up, and is rotated to the right, and a synchronous bar 21 is moved to the right. A lift arm is rotated to the left, and is raised through a small link, while a product is supported by its end, and is lifted. In this condition, a preceding bar 19 is moved to the left. The electromagnetic change over valves 33, 34 are changed over in reverse, and the piston rod 23a is pushed up, while the piston rod 24a is pulled down. At the time, since the lift arm is rotated to the right, and is pulled down, the product is put on a fixed board. One process is finished in this manner, and by repeating the process, carrier operation is proceeded.
