Abstract
A spring (11b) for a one-way clutch is provided that can suppress skewing of rollers and can restrain to a low level the stress generated due to bending of elastic pressure sections (23b1, 23b2). The spring (11b) is formed by subjecting an elastic metal plate to a bending process and comprises: a base section (22b) comprising a flat base-plate section (25); and a pair of elastic pressure sections (23b1, 23b2) formed by bending to an acute angle the both ends in the length direction of the base-plate section (25) towards the one side in the thickness direction of the base-plate section (25); and a pair of elbow sections (24a) located on the portions connecting the elastic pressure sections (23b1, 23b2) and the base-plate section (25). In particular, the elastic pressure sections (23b1, 23b2) cross each other in the middle sections in the length direction thereof.
