Since each panel body has a structure in which the upper portion is engaged and the lower portion is fitted, the panel bodies can be easily attached and replaced. The joint can be adjusted in its prospective direction by rotating the main body, so that it is easy to adjust the installed panel body in and out of the prospective direction. Since it is mounted by engaging and fitting with the joint, it is easy to absorb interlayer displacement and in-plane deformation of the panel body.

If the notches are provided at the corners of each panel body, there is almost no influence of interlayer displacement on the panel body itself, and the face plate mounted on the frame is not distorted. Therefore, the size of the frame to be found can be reduced. Further, the frames of the upper, lower, left and right panel bodies can be brought close to each other, and the joint size can be kept to the minimum necessary. This makes it possible to achieve a curtain wall with an elegant appearance.
