To provide an impact absorbing device that can absorb impact at both of a front collision and a rear collision, and a vehicular seat.SOLUTION: An impact absorbing device 5 of a vehicular seat 1 comprises a first base member 50 fixed to a seat cushion 2, a second base member 51 fixed to a seat back 3, and an impact absorbing member 52. The first base member 50 supports the second base member 51 turnably, which allows the seat back 3 to tilt on the basis of turning of the second base member 51. The impact absorbing member 52 has: a first fixed part 56 fixed to the first base member 50; a second fixed part 57 fixed to the second base member 51; and a deformed part 60, provided between the first fixed part 56 and the second fixed part 57, which can be bent by turning of the second base member 51, where a distance between the first fixed part 56 and the second fixed part 57 at the time when the deformed part 60 is not yet bent is a middle value in a variance range of the distance.SELECTED DRAWING: Figure 2

    【課題】前方衝突及び後方衝突の両方に対して衝撃吸収可能な衝撃吸収装置及び乗物用シートを提供する。【解決手段】乗物用シート1の衝撃吸収装置5は、シートクッション2に固定される第1ベース部材50と、シートバック3に固定される第2ベース部材51と、衝撃吸収部材52と、を備え、第1ベース部材50は、第2ベース部材51を回動可能に支持しており、第2ベース部材51の回動に基づいてシートバック3の傾倒を許容し、衝撃吸収部材52は第1ベース部材50に固定された第1固定部56と、第2ベース部材51に固定された第2固定部57と、第1固定部56と第2固定部57との間に設けられており、第2ベース部材51の回動によって曲げられる変形部60と、を有し、変形部60が曲げられる前の第1固定部56と第2固定部57との間の距離は、距離の変域の中間値である。【選択図】図2
