To provide a support structure of a vehicular seat capable of moving a seat to an optimum oscillation position in a lateral direction and a longitudinal direction without rotating the seat in a yaw direction.SOLUTION: A support structure of a vehicular seat 1 includes: a base member (11) which is mounted on a floor 8 of a vehicle V; an intermediate member (13) which is supported by the base member so as to be slidable in a first direction in a plan view through a first sliding mechanism 23; and a seat support member (15) which is supported by the intermediate member so as to be slidable in a second direction crossing the first direction in the plan view through a second sliding mechanism 26 and supports the seat 1. The first sliding mechanism 23 has a curved shaped track having a curvature center 23X at a position higher than a center of gravity C of the seat 1 including a seated person. The second sliding mechanism 26 has a curved shaped track having a curvature center 26X at a position higher than the center of gravity C of the seat 1 including the seated person.SELECTED DRAWING: Figure 1

    【課題】シートをヨー方向に回転させることなく横方向や前後方向について最適な揺動位置に移動させることができる車両のシート支持構造を提供する。【解決手段】車両用のシート1の支持構造であって、自動車Vのフロア8に取り付けられたベース部材(11)と、第1摺動機構23を介して平面視において第1方向に摺動可能にベース部材に支持された中間部材(13)と、第2摺動機構26を介して平面視において第1方向に交差する第2方向に摺動可能に中間部材に支持され、シート1を支持するシート支持部材(15)と、を備え、第1摺動機構23が着座者を含むシート1の重心Cよりも高い位置に曲率中心23Xを有する湾曲形状をなす軌道を有し、第2摺動機構26が着座者を含むシート1の重心Cよりも高い位置に曲率中心26Xを有する湾曲形状をなす軌道を有する。【選択図】図1
