Abstract
A frame body fixed to a membraneis divided into multiple long-side frame bodiesand a short-side frame body aligned in a peripheral direction of a frame. Tension is applied to the frame bodyby pulling each frame body. Accordingly, it is not necessary to make the shape of each frame bodyconsistent with the frame(support part) in a complicated polygonal shape, and the shape of each frame bodycan be formed as a linear shape. Therefore, the shape of each frame bodyhardly varies. In addition, even if the shape of each frame bodyvaries, tension can be uniformly applied to the membrane, as it is configured that each frame bodyis pulled to apply tension to the membrane
