The apparatus includes a rotating bracket member that is disposed within a wheel of a vehicle and includes movement space therein, and elastic bodies, each of which has a first end fixed to a substantial rotation center position of the rotating bracket member. In addition, the apparatus includes weight bodies which are fixed to a second end of the elastic body, and are configured to move within the movement space based on a rotation speed of the wheel of the vehicle, and selectively contact the rotating bracket member.
