PROBLEM TO BE SOLVED: To change a spring load energizing a sprag while maintaining an eigen frequency of a leaf spring part, without changing a main dimension of the leaf spring part, in a ribbon spring for a sprag type one-way clutch.SOLUTION: A leaf spring part 30 of a ribbon spring 13 has a narrow width part 31 formed between a bridge part 21 and the tip of the leaf spring part 30 in a circumferential direction. The narrow width part 31 has an effective length in an axial direction smaller than the effective length of the leaf spring part 30 other than the narrow width part 31 in the circumferential direction.SELECTED DRAWING: Figure 3 【課題】 スプラグ型一方向クラッチ用リボンスプリングにおいて、板ばね部の主寸法を変更することなく、板ばね部の固有振動数を維持したうえで、スプラグを付勢するばね荷重を変更する。【解決手段】 リボンスプリング１３の板ばね部３０は、周方向において架橋部２１と板ばね部３０の先端との間に狭幅部３１が形成されており、狭幅部３１は、軸方向の有効長さが、周方向における狭幅部３１以外の板ばね部３０の有効長さより小さい。【選択図】 図３
