PROBLEM TO BE SOLVED: To provide a lumbar support device with a simple structure that can be easily assembled.SOLUTION: A lumbar support device includes a slider 91 having pressing parts 91c and 91d which is moved by a drive mechanism, and a warp plate 31 which is provided with pressure receiving parts 31a and 31b pressed by the pressing parts 91c and 91d and which can adjust an extrusion amount to a seated person side by the pressing parts 91c and 91d. The pressing parts 91c and 91d are convex-shaped, and the pressure receiving parts 31a and 31b are concave-shaped. By the engagement of the pressing parts 91c and 91d with the pressure receiving parts 31a and 31b, the slider 91 and the warp plate 31 are connected to each other.SELECTED DRAWING: Figure 1
【課題】構造が簡単で、組付けが容易な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】駆動機構によって移動させられ、押圧部91c、91dを有するスライダ91と、押圧部91c、91dに押圧される押圧受け部31a、31bが設けられ、押圧部91c、91dにより着座者側への押し出し量を調整可能な反りプレート31と、を有し、押圧部91c、91dは凸状であり、押圧受け部31a、31bは凹状であり、押圧部91c、91dと押圧受け部31a、31bとが嵌合することで、スライダ91と反りプレート31とが接続される。【選択図】図1
