To enable the carrying work even in the field narrow in gap by engaging an engagement piece with a suspension rod restrict the suspension rod to a panel, and coupling a suspending means with one end part of the suspension rod to suspend the panel.

A counter-sunk hole 13 is formed in a circumferential edge of an opening of a suspension rod insertion hole 11, a hole 24 in a suspension rod 21 is positioned at the counter-sunk hole 13, an end part of the suspension rod 21 is prevented from being projected outward from a side edge 10a of a panel 10, a female screw 21a is formed in a face end of the suspension rod 21, a hook bolt 14 having a male screw 14a to be screwed in the female screw 21a is provided, the suspension rod 21 is substantially projected outward from the side edge 10a of the panel 10 by threadedly engaging the hook bolt 14 with the suspension rod 21, and the end part of the suspension rod 21 may be kept inside the side edge 10a by detaching the hook bolt 14 after completion of carriage. Since the suspension rod is little projected from the panel surface, this system is favorable for the work in a narrow working field.
