To provide a vehicular pedal device adapted to achieve by a comparatively simple configuration a construction that the depression angle in an initial movement range of pedal pad depression is taken great even if the fulcrum position of pedal arm rotation and the initial position of pedal pad depressing action are set in a comparatively narrow space range as viewed in a front-back direction in a rotational direction of the pedal arm.SOLUTION: A vehicular pedal device includes two link members 32 and 34 having a link-coupled structural arrangement that is link-coupled as (T1<(T2+T3+T4)) in which a distance (T2+T3+T4) obtained by adding a linear distance T2 between a fixed point D1 position and a movable point M1 position of the first link member 32, a linear distance T3 between a fixed point D2 position and a movable point M2 position of the second link member 34 and a linear distance T4 between the movable point M1 position of the first link member 32 and the movable point M2 position of the second link member 34 is longer than a linear distance T1 between the fixed points D1 and D2 positions of the first link member 32 and the second link member 34.SELECTED DRAWING: Figure 2 【課題】ペダルアームの回動支点位置とペダルパッドの踏込み作動初期位置とが、ペダルアームの回動方向の前後方向で見て、比較的狭いスペース範囲に設定される場合でも、ペダルパッド踏込みの初動範囲における踏込角を大きくとる構成を、比較的簡単な構成で達成する。【解決手段】２個のリンク部材３２、３４のリンク連結構成の配置は、第１リンク部材３２と第２リンク部材３４の固定点Ｄ１、Ｄ２位置間の直線距離Ｔ１より、第１リンク部材３２における固定点Ｄ１位置と可動点Ｍ１位置との間の直線距離Ｔ２と、第２リンク部材３４における固定点Ｄ２位置と可動点Ｍ２位置との間の直線距離Ｔ３と、第１リンク部材３２における可動点Ｍ１位置と前記第２リンク部材３４における可動点Ｍ２位置との間の直線距離Ｔ４とを加算した距離（Ｔ２＋Ｔ３＋Ｔ４）が長い距離（Ｔ１＜（Ｔ２＋Ｔ３＋Ｔ４））としてリンク連結されている。【選択図】図２
