PROBLEM TO BE SOLVED: To suppress deterioration in riding comfort during usual travelling of a vehicle and sufficiently secure a survival space for an occupant at a front collision of the vehicle.SOLUTION: An ECU 15, when determining that a state is a required preparation state, arranges head parts 27 of second stoppers 19L and 19R at operation positions, and when determining that the state is not the required preparation state, arranges the head parts 27 at retreating positions. In an operation state, since the head parts 27 are arranged at movable spaces 24 and approach first stoppers 16L and 16R, the first stoppers 16L and 16R contact with the head parts 27 immediately after a front collision, which promptly restricts a body 5 from moving forward with respect to a frame 2. In a retreating state, the head parts 27 are arranged outside the movable spaces 24, and the movable spaces 24 allow the first stoppers 16L and 16R and the second stoppers 19L and 19R to move relatively in a longitudinal direction, and allow the frame 2 and the floor member 12 to move relatively in the longitudinal direction.SELECTED DRAWING: Figure 2

    【課題】車両の通常走行時の乗り心地の低下を抑制し、且つ車両の前面衝突時の乗員の生存空間を十分に確保する。【解決手段】ECU15は、要準備状態であると判定した場合、第2ストッパ19L,19Rのヘッド部27を作動位置に配置し、要準備状態ではないと判定した場合、ヘッド部27を退避位置に配置する。作動状態では、ヘッド部27が可動空間24内に配置されて第1ストッパ16L,16Rに近接するので、前面衝突の直後に第1ストッパ16L,16Rとヘッド部27とが当接し、フレーム2に対するボディ5の前方への移動が迅速に規制される。退避状態では、ヘッド部27が可動空間24外に配置されて、可動空間24が、第1ストッパ16L,16Rと第2ストッパ19L,19Rとの相対的な前後方向の移動を許容し、フレーム2とフロア部材12との前後方向の相対的な移動を許容する。【選択図】図2
