    • PROBLEM TO BE SOLVED: To provide an electric brake system capable of suitably controlling a motor even when operated to start a vehicle just after completion of system-up. SOLUTION: When a predetermined system-down condition is prepared (SA7), a state detection control means controls to detect the state by a state detection means (SA8) and then system-down is conducted after the detection result is stored in a storage means (SA9). Even when the electric bake system is operated to start the vehicle just after the completion of the system-up, for example by turning an ignition key from off to on, a motor control means controls the motor based on the storage content of the storage means and the detection result of the state detection just before the completion of the system-down exists in the storage content of the storage means. Therefore, the motor can be suitably controlled by the content of the storage.

    • PROBLEM TO BE SOLVED: To provide an electric brake which is excellent in both responsibiveness during an initial brake operation and power transmission efficiency after frictional engagement between a brake pad and a braked member. SOLUTION: This device has a power transmission converting mechanism 4 for receiving a drive power of an electric motor to press a brake member 6 against a braked member 7. In this case, the power transmission converting mechanism 4 is composed of a gear 13 rotated by the electric motor, a nut 18 arranged opposite to the gear 13 and a rotary body arranged between the gear 13 and the nut 18, and further has a ramp mechanism for separating the nut 18 from the gear 13 through a relative rotation between the gear 13 and the nut 18, an irrotational screw member 31 threadedly engaged with the nut 18 and a brake member 6 to functionally abut against the screw member 31. The ramp mechanism unitedly rotates the gear 13 and the nut 18 until the brake member 6 abuts against the braked member 7 under fixed pressing force, and when the abutting force becomes more than the above fixed value, allows a relative rotation between the gear 13 and the nut 18 to make the nut 18 movable toward the braked member.
