Zusammenfassung:To provide a vehicular seat in which a radio wave sensor can be disposed without hindering operations of a support member and a pressure receiving member.SOLUTION: A vehicular seat has in a seat back: a plate-like pressure receiving member 40 that receives a load from a seated person; a support member 50 that supports the pressure receiving member 40 from a rear side and changes the shape of the pressure receiving member 40; and a radio wave sensor 100. The support member 50 has: a lower lifting/lowering plate 54; an upper lifting/lowering plate 55 which moves vertically; an arch member 58 which is deformable in a deflected manner and one end of which is fixed to the lower lifting/lowering plate 54 and the other end of which is fixed to the upper lifting/lowering plate 55, wherein, when the upper lifting/lowering plate 55 moves closer to the lower lifting/lowering plate 54, the arch member 58 bends forward to pressurize the pressure receiving member 40 forward. The pressure receiving member 40 has: a middle portion 41 located at the middle in a right and left direction and pressurized by the arch member 58; and right and left side portions 42 arranged in both the right and left sides of the middle portion 41. A radio wave sensor 100 is attached to each side portion 42.SELECTED DRAWING: Figure 4 【課題】支持部材および受圧部材の動作を妨げることなく、電波センサを配設することができる乗物用シートを提供する。【解決手段】乗物用シートは、シートバック内に、着座者からの荷重を受ける板状の受圧部材40と、受圧部材40を後側から支持し、受圧部材40の形状を変化させる支持部材50と、電波センサ100とを備える。支持部材50は、下側昇降板54と、上下に移動する上側昇降板55と、一端が下側昇降板54に固定され、他端が上側昇降板55に固定された撓み変形可能なアーチ部材58であって、上側昇降板55が下側昇降板54に近接する方向に移動するときに前側に撓んで受圧部材40を前側に押圧するアーチ部材58とを有する。受圧部材40は、左右方向における中央に位置し、アーチ部材58によって押圧される中央部41と、中央部41の左右両側に配置された左右の側部42とを有する。電波センサ100は、側部42に取り付けられている。【選択図】図4
