To provide a reclining device capable of suppressing unlock of an engagement state caused by the inertial force in a walk-in mechanism while avoiding deterioration of operability during unlocking.SOLUTION: An embodiment of the present disclosure is a reclining device of a vehicle seat. The reclining device comprises: a tilt member transmitting oscillation force to a back frame; an engaging member connected to an oscillatable part of a frame of the vehicle seat relatively to the tilt member, which can oscillate between an engaging position to be engaged with the tilt member and un-engaging position where engagement is released; a regulation member which can oscillate between a regulation position to regulate oscillation from the engaging position of the engaging member to the un-engaging position and a non-regulation position not to regulate oscillation; and an operation member in which the regulation member is oscillated from the regulation position to the non-regulation position by oscillating from a lock position to an unlock position, and the engaging member is oscillated from the engaging position to the un-engaging position. Oscillation direction of the engaging member crosses oscillation direction of the regulation member.SELECTED DRAWING: Figure 1 【課題】ロック解除時の操作性の低下を避けつつ、ウォークイン機構における慣性力による係合状態の解除を抑制できるリクライニング装置を提供する。【解決手段】本開示の一態様は、乗物用シートのリクライニング装置である。リクライニング装置は、揺動力をバックフレームに伝達する傾倒部材と、乗物用シートのフレームのうち、傾倒部材に対して相対的に揺動可能な部分に連結され、傾倒部材と係合する係合位置と係合が解除された非係合位置との間で揺動可能な係合部材と、係合部材の係合位置から非係合位置への揺動を規制する規制位置と揺動を規制しない非規制位置との間で揺動可能な規制部材と、ロック位置からロック解除位置への揺動によって、規制部材を規制位置から非規制位置へ揺動させつつ、係合部材を係合位置から非係合位置へ揺動させる操作部材とを備える。係合部材の揺動方向と、規制部材の揺動方向とは、交差している。【選択図】図１
