PROBLEM TO BE SOLVED: To reduce the maximum deceleration of an occupant by enhancing ride-down efficiency at a front face collision of a vehicle.SOLUTION: A stopper device 10 comprises a first stopper 15 fixed to a floor member 12, and a second stopper 16 fixed to a frame 2. In the second stopper 16, a support member 21 is fixed to the frame 2, a movable member 22 is movably supported to the support member 21 in a fore-and-aft direction, and a collar 23, a socket 24 and a fuse bolt 25 hold a position of the movable member 22 with respect to the support member 21 at a first regulation position. After a vehicle 1 collides at a front face, and the movable member 22 of the second stopper 16 in the first regulation position and the first stopper 15 abut on each other, when the deceleration of a body 5 exceeds a threshold K, the holding of the movable member 22 to the first regulation position with respect to the support member 21 is released. The movable member 22 which has arrived at a second regulation position from the first regulation position regulates the movement of the body 5 to a front part with respect to the frame 2 once again.SELECTED DRAWING: Figure 4

    【課題】車両の前面衝突時にライドダウン効率を高めて乗員の最大減速度を低減する。【解決手段】ストッパ装置10は、フロア部材12に対して固定される第1ストッパ15と、フレーム2に対して固定される第2ストッパ16とを備える。第2ストッパ16は、支持部材21がフレーム2に固定され、可動部材22が支持部材21に前後方向に移動可能に支持され、カラー23、ソケット24、及びヒューズボルト25が支持部材21に対する可動部材22の位置を第1規制位置に保持する。車両1が前面衝突して、第1規制位置の第2ストッパ16の可動部材22と第1ストッパ15とが当接した後、ボディ5の減速度が閾値Kを超えると、支持部材21に対する可動部材22の第1規制位置への保持が解除される。第1規制位置から第2規制位置に到達した可動部材22は、フレーム2に対する前方へのボディ5の移動を再度規制する。【選択図】図4
