    Abstract: An electric brake device is disclosed. The electric brake device includes a reservoir configured to store brake oil; a reaction force cylinder fluidically communicating with the reservoir and configured to change a pedal effort and a pressure of the brake oil in operative connection with a movement of a pedal; a wheel brake mechanism configured to restrain rotation of wheels of a vehicle in connection with the operation of the reaction force cylinder; and a pedal effort adjustment stopper configured to adjust a change in magnitude of the pedal effort according to the movement of the pedal, the pedal effort adjustment stopper comprising a coupling body mounted on at least one side of the reaction force cylinder and one or more pedal effort adjusters connected to the coupling body and movable in a longitudinal direction of the reaction force cylinder.
