PROBLEM TO BE SOLVED: To enhance performance of a reclining structure in which a seat back is fixed to a vehicle body side part in a state that angle of a backrest can be adjusted, and simplify it.SOLUTION: A reclining structure REC comprises: a connection shaft which is a tilt center of a seat back 2; a slide rail 10 which is arranged at a vehicle body side part BF, and curved in a circular arc shape around the connection shaft; a slider 20 which is slidably assembled on the slide rail 10; a detachable structure 30 in which the seat back 2 is attached to/detached from the slider 20; and a slide lock structure 40 which locks slide of the slider 20. The slide lock structure 40 comprises: a lock member 41 which is assembled with the slider 20 in which the lock member is slidable in a radial direction; a cam member 42 which is assembled with the slider 20 to be operated so as to extrude the lock member 41 in the radial direction; and a lock tooth 49 formed with the slide rail 10 in which a tooth surface faces in the radial direction so as to be engaged with the lock member 41 sliding in the radial direction.

    【課題】シートバックを車体側部に背凭れ角度の調整を行える状態に固定するリクライニング構造を、高性能かつ簡素にすること。【解決手段】リクライニング構造RECは、シートバック2の傾動中心となる連結軸と、車体側部BFに設けられて連結軸まわりの円弧形状に湾曲したスライドレール10と、スライドレール10にスライド可能な状態に組み付けられたスライダ20と、スライダ20にシートバック2を着脱させる着脱構造30と、スライダ20のスライドをロックするスライドロック構造40とを有する。スライドロック構造40は、スライダ20に対して径方向にスライド可能な状態に組み付けられたロック部材41と、ロック部材41を径方向に押し出すようにスライダ20に組み付けられて作動するカム部材42と、スライドレール10に径方向に歯面を向けて形成され径方向にスライド操作されたロック部材41を噛合させるロック歯49と、を有する。【選択図】図5
