PROBLEM TO BE SOLVED: To reduce a retreating moving amount of a brake pedal when load is applied from the vehicle front side. SOLUTION: A link mechanism 20 for moving a brake pedal arm 17 to the front side is provided between a push rod 11 of a brake booster 2 and the brake pedal 5. A lower end face 33a engageable to a shaft-shaped member 24 provided on the link mechanism 20 is provided on a joint yoke 33. When space between a dash panel 8 and the joint yoke 33 is narrowed due to deforming of the dash panel 8 backward by receiving load from the front side, the link mechanism 20 is rotated to move the brake pedal arm 17 to the front side because the shaft-shaped member 24 is regulated by the lower end face 33a.
