PROBLEM TO BE SOLVED: To enhance latch strength in the axial direction by an outer peripheral ring.SOLUTION: An outer peripheral ring 90 is mounted over the outer peripheral parts of a ratchet 10 and a guide 20 both disposed in a recliner 4, and functioning to latch them in the axial direction, the outer peripheral ring 90 including: a press part 91 for being abutted against the outer peripheral part of the ratchet 10 from outside in the axial direction; and a connection part 92 for being connected to the outer peripheral part of the guide 20. The connection part 92 is configured to be connected to the outer peripheral part by being caulked to the outer peripheral part of the guide 20 in a sandwiching manner from both sides in the axial direction; some parts of the connection part 92 in the circumferential direction form caulking pieces 92A for being caulked to the outer peripheral part from a position extending outside in the axial direction toward inside in the radial direction. Since the end parts 92A2 at the top of the bent portions of caulking pieces 92A are bent into recessed parts 24D formed on the outside face of the guide 20 in the axial direction, a movement toward outside in the radial direction becomes a hooked state. 【課題】外周リングによる軸方向の外れ止め強度を向上させる。【解決手段】リクライナ４のラチェット１０とガイド２０との外周部間に跨って装着されてこれらの軸方向の外れ止めをする外周リング９０は、ラチェット１０の外周部に軸方向の外側からあてがわれる押さえ部９１と、ガイド２０の外周部に結合される結合部９２と、を有する。結合部９２は、ガイド２０の外周部を軸方向の両側から挟むようにかしめられることで同外周部に結合される構成とされ、その円周方向の一部箇所が上記外周部を軸方向の外側に越えた位置から半径方向の内側にかしめられるかしめ片９２Ａとされて、かしめ片９２Ａは、その曲げられた先の端部９２Ａ２がガイド２０の軸方向の外側面に形成された凹部２４Ｄ内に折り曲げられることで半径方向の外側への移動が掛止された状態とされている。【選択図】図７
