PROBLEM TO BE SOLVED: To provide a one-way clutch which includes a holder with a plurality of elastic pieces arranged therein and in which deformation of the holder into a tapered shape by reaction force generated upon warping of the elastic piece is suppressed,.SOLUTION: A holder (16) includes a plurality of window portions (16A) and a plurality of elastic pieces (28). The plurality of window portions are formed at equal intervals in the circumferential direction around a center axis (L) of a one-way clutch (10). The plurality of elastic pieces are disposed at equal intervals in the circumferential direction, and come in contact with one of an inner ring (12) and an outer ring (14). Each of the plurality of elastic pieces is disposed between two window portions adjacent to each other in the circumferential direction, and includes a first elastic piece (28A) and a second elastic piece (28B). One end in the axial direction where the center axis is extended, of the first elastic piece is a fixed end, and the other end in the axial direction is a free end. One axial-direction end of the second elastic piece is a free end, and the other axial-direction end is a fixed end. The free ends of the first elastic piece and the second elastic piece come in contact with one of the inner ring (12) and the outer ring (14). 【課題】複数の弾性片が配置された保持器を備えるワンウェイクラッチにおいて、弾性片が撓んでいるときの反力により、保持器がテーパ状に変形するのを抑制する。【解決手段】保持器（１６）は、複数の窓部（１６Ａ）と、複数の弾性片（２８）とを含む。複数の窓部は、ワンウェイクラッチ（１０）の中心軸線（Ｌ）周りの周方向に等間隔に形成されている。複数の弾性片は、周方向に等間隔に配置され、内輪（１２）及び外輪（１４）の一方に接触する。複数の弾性片の各々は、周方向で隣り合う２つの窓部の間に配置され、第１弾性片（２８Ａ）と、第２弾性片（２８Ｂ）とを含む。第１弾性片においては、中心軸線が延びる軸方向の一端が固定端であって、且つ、軸方向の他端が自由端である。第２弾性片においては、軸方向の一端が自由端であって、且つ、軸方向の他端が固定端である。第１弾性片及び第２弾性片の自由端が一方の部材に接触する。【選択図】図１
