To provide an overstepping sudden start prevention accelerator pedal device with a mechanical structure which is excellent in reliability and can be attached to a vehicle that adopts an electronic throttle type accelerator pedal and an acceleration and brake device for the vehicle.SOLUTION: An overstepping sudden start prevention accelerator pedal device can perform a normal braking operation alone. At a safe limit rotation angle around a main shaft of an input piece stem or less, the input piece stem and an output piece stem are integrally connected to achieve a normal acceleration/deceleration operation of a vehicle with an operation of an accelerator pedal member. At the safe limit rotation angle or greater, the integration between the input piece stem and the output piece stem is released to return the accelerator pedal member to the initial state. The input piece stem is rotated around the main shaft up to a pedal acceleration limit rotation angle to actuate a brake link mechanism to perform the braking operation of the brake pedal.SELECTED DRAWING: Figure 1

    【課題】電子スロットル方式のアクセルペダルを採用する車両に装着可能な信頼性に優れた機械的な構造の過踏込み急発進防止アクセルペダル装置及び車両の加速・制動装置を提供する。【解決手段】本過踏込み急発進防止アクセルペダル装置は、単独で通常の制動操作をすることができ、入力こまステムの主軸回りの安全限界回転角未満において、前記入力こまステムと出力こまステムは一体に接続されてアクセルペダル部材の操作により車両の通常の加減速操作ができ、安全限界回転角以上において前記入力こまステムと出力こまステムの一体性が解除されて前記アクセルペダル部材が初期状態に復帰するとともに、前記入力こまステムはペダルアクセル限界回転角まで主軸回りに回動してブレーキリンク機構を作動させ前記ブレーキペダルの制動操作を行う。【選択図】図1
