A pedal bracket is divided into a main bracket and a sub-bracket. The main bracket and the sub-bracket are connected by a mounting bolt and a nut, the mounting bolt serving as a supporting shaft of a swing link which connects a brake pedal and a push rod. When an external force of a predetermined value or greater is applied to the front of the vehicle, an extending portion of the sub-bracket is pressed by the main bracket and swings substantially rearward of the vehicle and a clevis at the end of the push rod is forced in substantially toward the front side of the vehicle by a front surface of the extending portion. Accordingly, the brake pedal swings around a mounting bolt substantially toward the front side of the vehicle via the swing link and the like and a pedal pad is displaced substantially toward the front side of the vehicle.
