However, since the transport device grips the outer wall panel only at its upper end, the outer wall panel shakes. Therefore, it is necessary to provide an anti-sway device for the outer wall panel on the ground side, which causes a problem that the device becomes complicated.

In addition, when the self-propelled trolley travels, the gripping portion must be raised to the original position each time, and the transfer efficiency is not so good. Furthermore, since a control device for raising and lowering the gripper is required for each overhead traveling carriage, the manufacturing cost has increased significantly.

Accordingly, the present invention has been devised to solve the above-mentioned problems, and has as its object the purpose of having a simple structure, preventing the shaking of the outer wall panel during finishing work, and improving the transfer efficiency. An object of the present invention is to provide a transfer device for finishing an outer wall panel that can be manufactured at low cost.
