To solve a serious problem in an aging automobile society, that is, how to prevent a runaway accident due to wrong stepping on an accelerator pedal that may be caused by abruptly stepping on the accelerator pedal as the accelerator pedal is mistook for the brake pedal.SOLUTION: An expandable case 1 mounted with a control valve 22 is installed below an accelerator pedal 31, and an elastic material 23 is mounted which retains the control pedal 22 so that the control valve is not closed when pressed with stepping force by normal accelerator operation, so that the case 1 shrinks as internal air flows out. If the accelerator pedal 31 is stepped on with abrupt strong stepping force, the control valve 22 applied with abruptly rising internal pressure in the case 1 compresses the elastic material 23 and then the control valve 22 is closed to stop the case 1 from shrinking, so the accelerator pedal cannot be stepped on.SELECTED DRAWING: Figure 5
【課題】アクセルペダルをブレーキペダルと誤認し、アクセルペダルを急激に踏み込んで発生する、いわゆるアクセルペダルの踏み間違いによる暴走事故をいかに防止するか、高齢化が進む車社会の大きな課題となっている。【解決手段】アクセルペダル31の下部に、制御弁22を装着した伸縮可能なケース1を設置し、通常のアクセル操作による踏力で押された場合は、制御弁22が閉じないように保持する弾性材23を装着し、ケース1が内在する空気の流出により収縮する構造にしている。アクセルペダル31が急激な強い踏力で踏まれると、ケース1内の急上昇した内圧を印加された制御弁22が、弾性材23を圧縮し制御弁22が閉じてケース1の収縮を停止するため、アクセルペダルが踏み込めなくなる。【選択図】図5
