To easily release a restriction caused by a locking mechanism from either a front side direction or a rear side direction of a seat back, and to easily perform a tilting operation of the seat back.SOLUTION: A locking release mechanism 50 of a seat device 10 includes: a concavity 33 provided across a rear face 62b from a top face 62a of a seat back 62 at an upper end of the seat back 62; and an operation lever 20 which releases the locking caused by a locking mechanism 40 by being rotationally operated outward of the concavity 33 from a non-operation position accommodated inside the concavity 33. The operation lever 20 includes: a lever body 20A; and a shaft part 20B which extends along a width direction of the seat back 62 on a front side and an upper side inside the concavity 33, and which is a rotation center of the lever body 20A. The lever body 20A has: an extension part 22 extending rearward beyond the shaft part; and an operation part 23 extending downward from a rear part of the extension part 22.SELECTED DRAWING: Figure 5

    【課題】シートバックの前方及び後方のいずれの方向からでもロック機構による規制の解除及びシートバックの傾動操作を簡単に行うこと。【解決手段】シート装置10のロック解除機構50は、シートバック62の上端部においてシートバック62の上面62aから後面62bにわたって設けられた凹部33と、凹部33内に収容されている非操作位置から凹部33の外方に向けて回動操作されることでロック機構40によるロックを解除する操作レバー20とを備えている。操作レバー20は、レバー本体20Aと、凹部33内の前側且つ上側においてシートバック62の幅方向に沿って延びるとともにレバー本体20Aの回動中心となる軸部20Bとを備え、レバー本体20Aは、軸部よりも後方に延びる延在部22と、延在部22の後部から下方に延びる操作部23とを有している。【選択図】図5
