    Abstract: Provided is a stretching structure for stretched member, whereby a frame can be manufactured inexpensively without the use of complex and expensive dies, and a stretched material having an attractive external appearance, particularly the external appearance in back view and side view, is obtained through a simple stretching operation. In a stretching structure for a stretched member (28) stretched onto a back frame (27) serving as the frame, the back frame (27) is equipped with a main frame member (32), the surface of which abuts the stretched member (28); and an upper auxiliary frame member (33) fastened to the back surface of at least a portion of the main frame member (32). The stretched member (28) is looped in succession about the outside peripheral surface of the main frame member (32) from the front side, and along the outside peripheral surface, the back surface, and the inside peripheral surface of the upper auxiliary frame member (33), affixing the outside peripheral edge portion of the stretched member (28) to the upper auxiliary frame member (33) at the surface thereof opposing the back surface of the main frame member (32).
