Since other components are the same as those of the conventional apparatus, description thereof is omitted. Moreover, the same code | symbol has shown the identical part through each figure.

  Next, the operation of the first embodiment configured as described above will be described. First, the clip member 3 is separated from the insertion holes 24A and 24B of the adjacent wall panels 2A and 2B at the front end side of the clip member 3 at a predetermined portion of the folded piece 23A of the adjacent one of the wall panels 2A. The clip member 3 is pushed in so as to enter the back surface side, the fixing portion 31 of the clip member 3 is brought into close contact with the folded piece 23A, and is fixed with a bolt 4 or a rivet (not shown) using the fixing hole 31a. Similarly, a plurality of clip members 3 are all attached. Next, the wall panel 2A to which the clip member 3 is attached is attached to a frame member such as a floor frame (not shown) constituting the cab 1. Since this attachment method is completely the same as the prior art, detailed description thereof will be omitted, but in the example of FIG. 2, among the wall panels 2 on the right side of the figure, the upper side of the figure is one wall panel 2A and the lower side is the other. Corresponds to the wall panel 2B.

  Next, the other wall panel 2B is prepared, and the abutting portion 33 on the other end side of the clip member 3 is inserted through the insertion hole 24B of the folded piece 23B to resist the biasing force of the spring on the other end side. The connecting portion 22B is pushed between the pressing portions 32 and 32 while expanding the pressing portion 32, and the other wall panel 2B is moved until the abutting portion 33 contacts the back surface of the main surface portion 21B of the other wall panel 2B. Push in from the indoor side to the outdoor direction. When the other wall panel 2B is pushed in, the top or bottom of the wall panel 2B is tilted forward, and the contact portions 33 of the clip members 3 provided at, for example, 5 to 7 locations in the up-down direction are sequentially folded back pieces 23B. The fitting operation is facilitated by fitting into the insertion hole 24B. In the operation of attaching the other wall panel 2B as described above, the contact portion 33 of each clip member 3 serves as a stopper for preventing a step, and the connecting portion with the one wall panel 2A is always connected in a flat state. Further, the fastening work on the hoistway side can be eliminated.
