To stabilize tread force of an accelerator pedal even when there are various variation of dimension errors, assembling errors and so on.SOLUTION: An accelerator pedal device for a motor vehicle comprises an accelerator arm 14 which is provided with a drum part 22 on one end part in an axial direction and is provided with a pedal part 28 on the other end part in the axial direction, a friction pad 16 which is attached in a manner capable of turning with respect to a housing 12 forming a pad axial part 38 as a center of turning and a spring member 18 which is interposed between the accelerator arm 14 and the friction pad 16. The drum part 22 includes an arm turning axis 24 which pivotally supports the accelerator arm 14 in a manner capable of turning and a recess 34 which dents from an outer peripheral part toward the arm turning axis 24. The friction pad 16 includes a friction part 40 which is pressed downward to the recess 34 by spring force of the spring member 18. The friction part 40 includes a side surface member 30 which is formed with a lateral part 50 facing the recess 34 in arc shape in cross sectional view. The side surface member 30 includes a contact part 52 which makes a point contact with respect to the recess 34 of the drum part 22.SELECTED DRAWING: Figure 5
【課題】寸法誤差や組付誤差等の各種バラツキがあった場合であっても、アクセルペダルの踏力を安定化させること。【解決手段】軸方向に沿った一端部にドラム部22が設けられていると共に、軸方向に沿った他端部にペダル部28が設けられているアクセルアーム14と、パッド軸部38を回動中心としてハウジング12に対して回動可能に取り付けられている摩擦パッド16と、アクセルアーム14と摩擦パッド16との間に介装されるばね部材18とを備え、ドラム部22は、アクセルアーム14を回動可能に軸支するアーム回動軸24と、外周部からアーム回動軸24に向かって窪む凹部34とを有し、摩擦パッド16は、ばね部材18のばね力によって凹部34に押圧される摩擦部40を有し、摩擦部40は、凹部34に臨む側面部50が断面円弧状に形成された側面部材30を有し、側面部材30は、ドラム部22の凹部34に対して点接触する接触部52を有する。【選択図】図5
