To reduce cost of a seat reclining device.SOLUTION: A seat reclining device 1 has a recliner 5, a first bracket 6, an operation shaft 9, and a spring member 11 mounted on the operation shaft 9. A spring member 11 has one end 11a wound around one end 47 of the operation shaft 9. The one end 47 of the operation shaft 9 is formed so that a tip side of the one end 47 is twisted around an axial line C of a central axis with respect to a base end side. The operation shaft 9 applies twisting to the one end 47, and thereby the one end 11a of the spring member 11 can be strongly mounted. Therefore, a length in an axial direction of a part with a cross-sectional shape having a corner part 46 around which the one end 11a of the spring member 11 is wound can be set to be short, and processing cost can be reduced.SELECTED DRAWING: Figure 1

    【課題】シートリクライニング装置のコスト低減を図る。【解決手段】シートリクライニング装置1は、リクライナ5と、第1ブラケット6と、操作軸9と、操作軸9に取り付けられるばね部材11と、を有している。ばね部材11は、一端部11aが操作軸9の一端部47に巻かけられている。操作軸9の一端部47は、一端部47の先端側が基端側に対して中心軸軸線C周りに捩られた形状となるよう形成されている。操作軸9は、一端部47に捩れを加えることでばね部材11の一端部11aを強固に取り付けることが可能となる。そのため、ばね部材11の一端部11aが巻かけられる角部46を有する断面形状の部分の軸方向に沿った長さ短く設定することが可能となり、加工コストを低減することができる。【選択図】図1
