Abstract: The present disclosure includes: a cylinder; a piston that moves inside the cylinder in response to the operation of a brake pedal; a reactive rubber that is disposed inside the cylinder and that applies a reactive force to the piston by being compressed by the movement of the piston to one side; and a plug that is disposed inside the cylinder so as to surround an outer circumferential surface of the reactive rubber and that increases a sliding resistance against the movement of the reactive rubber to one side as the reactive rubber is compressed.
