Summary:PROBLEM TO BE SOLVED: To provide a vehicle seat that has a walk-in mechanism allowing a slide lock in a fixed position after a walk-in operation even in a forward inclining position of a seat back.SOLUTION: A vehicle seat comprises: a lower rail 10 (first rail); an upper rail 20 (second rail); a slide lock mechanism 30 that locks or unlocks a lock hole 15 (locking part) at a lower rail 10 side and a lock claw 31 (unlocked part) at an upper rail 20 side in an area where they are able to be selectively locked in a plurality of positions in a longitudinal direction; and a walk-in mechanism 40. The walk-in mechanism 40 comprises: a retaining mechanism unit that comprises a projection bracket 100 (a transfer preparation mechanism unit) set in a position further forward than a lockable area 35 at the lower rail 10 side and that retains an unlocked state by the slide lock mechanism 30 at the upper rail 20 side; and an un-retaining mechanism unit that brings the unlocked state into a state allowing shift to a locking state.SELECTED DRAWING: Figure 2 【課題】シートバックが前倒れ状態でもウォークイン操作後に定位置でスライドロックを可能とするウォークイン機構を有する乗物用シートとする。【解決手段】ロアレール10(第1レール)と、アッパレール20(第2レール)と、ロアレール10側の係止孔15(係止部)と、アッパレール20側のロック爪31(被係止部)とが長手方向の複数位置で選択的に互いに係止される係止可能領域内において係止または係止解除させるスライドロック機構30と、ウォークイン機構40と、を有する乗物用シートであって、ウォークイン機構40には、ロアレール10側において係止可能領域35より前方側の位置に設定される突出ブラケット100(移行準備機構部)が構成され、アッパレール20側においてスライドロック機構30による係止解除状態を維持させる維持機構部と、係止解除状態を係止状態に移行可能な状態とする維持解除機構部が構成される。【選択図】図2
