PROBLEM TO BE SOLVED: To fix a direction in which a holder intermittently minute-rotates to an outer ring member in one direction, in a one-way clutch.SOLUTION: A one-way clutch is equipped with a plurality of sprags disposed between an outer ring member 5 and an inner ring member 6; and an annular holder 3 which holds the sprags at intervals in a circumferential direction. The holder 3 has an annular flange portion 34 which is integrated with an annular body portion formed with pockets for holding the sprags. The flange portion 34 has recessed/projecting portions 37 capable of contacting with an inner peripheral surface 5a of the outer ring member 5, on at least a part in the circumferential direction. Projecting portions 38 of the recessed/projecting portions 37 have projecting shapes which are asymmetric on one side and the other side in the circumferential direction with reference to a virtual line in a diametrical direction.SELECTED DRAWING: Figure 5 【課題】一方向クラッチにおいて、外輪部材に対して保持器が間欠的に微小回転する方向を一方とする。【解決手段】一方向クラッチは、外輪部材５と内輪部材６との間に配置される複数のスプラグと、これらスプラグを周方向に間隔をあけて保持するための環状の保持器３とを備えている。保持器３は、スプラグを保持するポケットが形成されている環状の本体部と一体である環状のフランジ部３４を有している。フランジ部３４は、周方向の少なくとも一部に、外輪部材５の内周面５ａに接触可能である凹凸部３７を有している。凹凸部３７が有する凸部３８は、径方向の仮想線を基準として周方向一方側と他方側とで非対称の凸形状を有している。【選択図】 図５
