Abstract
A spring is assembled in an annular shape into a one-way clutch to urge engagement members disposed between inner and outer races of the one-way clutch in one direction. In the spring, first and second transverse sections are alternately provided. Those first and second transverse sections define receiving openings which have a generally rectangular shape adapted to receive the engagement members therein. Each first transverse section has a tab projecting into the respective receiving opening so as to press an engagement member received in the receiving opening. The first and second transverse sections also define adjusting openings which are provided alternately with the receiving openings for adjusting the widths of at least the first transverse sections. Each adjusting opening is of a generally rectangular shape and is provided with curved fillets protruding outwardly in a crosswise direction of the spring, so that the widths of the first transverse sections are prevented from becoming larger than those of the tabs even at their end portions.
