PROBLEM TO BE SOLVED: To provide a lumbar support device which smoothly deforms a warp plate.SOLUTION: A lumber support device has: a warp plate 31 in which an upper part is rotatably supported by a seat back frame 5 provided at a seat back for supporting a back part of a seating person; and a drive mechanism which rotatably supports a lower part of the warp plate 31 and drives the lower part of the warp plate 31 in a vertical direction. A low rigid part LR having lower rigidity is formed at an intermediate part of the warp plate 31.SELECTED DRAWING: Figure 1

    【課題】円滑に反りプレートを変形できるランバーサポート装置を提供することを課題とする。【解決手段】着座者の背部を支持するシートバックに設けられるシートバックフレーム5に上部が回転可能に支持される反りプレート31と、該反りプレート31の下部を回転可能に支持し、前記反りプレート31の下部を上下方向に駆動する駆動機構とを有するランバーサポート装置であって、前記反りプレート31の中間部には、剛性が低い低剛性部LRが形成されている。【選択図】図1
