To provide a cloth spring tension structure which can achieve reduction in the weight and cost, can freely adjust a tension of a cloth spring, and easily re-adjusts the tension to the optimal state even when the tension is weakened with secular change.SOLUTION: A cloth spring tension structure includes a pair of fitting side parts 11 and 12 which are arranged so as to face each other, and a cloth spring 20 mounted in a state of being bridged between each of the fitting side parts 11 and 12, in which the cloth spring 20 has each end edge 23 and 24 which are arranged so as to face each other on both sides in a portion in contact with each of the fitting side parts 11 and 12 extending by only a tension between each of the fitting side parts 11 and 12, and one fitting side part 11 is steplessly movable in a direction close to or separated from the other fitting side part 12 and can freely adjust a tension of the cloth spring 20 by the movement.SELECTED DRAWING: Figure 1
【課題】軽量化およびコストダウンを実現することができ、布バネの張力を容易かつ自由に調整することができ、布バネが経年変化により張力が弱まっても、容易に再調整して最適な状態にすることができる布バネの張り構造を提供する。【解決手段】相対向して配置される一対の取付辺部11,12と、各取付辺部11,12の間に掛け渡された状態に装着される布バネ20と、を有し、布バネ20は、各取付辺部11,12に接している部分の両側で相対向する各端縁23,24が、各取付辺部11,12間における張力のみで延びた状態にあり、一方の取付辺部11は、他方の取付辺部12に対して離隔ないし近接する方向に無段階に移動可能であり、該移動によって布バネ20の張力を自由に調整することができる。【選択図】図1
