PROBLEM TO BE SOLVED: To provide a retreat prevention device of a vehicle pedal device capable of suppressing deformation of a vehicle side member to a vehicle rear side, and suppressing retreat of an operation pedal, when a dash panel is displaced to a vehicle rear side.SOLUTION: A brake pedal device 1 comprises: a pedal bracket 10; an operation pedal 20; an intermediate lever 25; a connection link 30; a link mechanism part 40; and a first link fixing part. The link mechanism part 40 is formed of the pedal bracket 10, an upper side link member 41, a lower side link member 42, and an intermediate link member 43, namely forms a four-joint link mechanism. When front collision of the vehicle occurs, the brake pedal device 1 displaces downward constitution members of the link mechanism part 40, through a guide bracket 60, for downward moving a second support shaft 12. Therefore, since the intermediate lever 25 also moves downward with the second support shaft 12, the operation pedal 20 rotates around a first support shaft 11 to a vehicle front side through the connection link 30.SELECTED DRAWING: Figure 4 【課題】ダッシュパネルが車両後側へ変位した場合に、車両後方側への車体側部材の変形と共に、操作ペダルの後退を抑制可能な車両用ペダル装置の後退防止装置を提供する。【解決手段】ブレーキペダル装置１は、ペダルブラケット１０と、操作ペダル２０と、中間レバー２５と、連結リンク３０と、リンク機構部４０と、第１リンク固定部等を有している。リンク機構部４０は、ペダルブラケット１０と、上側リンク部材４１と、下側リンク部材４２と、中間リンク部材４３からなり、所謂、四節リンク機構を構成する。車両の前方衝突があった場合、ブレーキペダル装置１は、ガイドブラケット６０を介して、リンク機構部４０の構成部材を下方に変位させ、もって、第２支持軸１２を下方へ移動させる。これにより、中間レバー２５も第２支持軸１２と共に下方に移動する為、操作ペダル２０は、連結リンク３０を介して、第１支持軸１１まわりに車両前方側へ回動する。【選択図】図４
