<p>An electric brake device includes a disc rotor (42) which is rotatable together with a wheel of an automotive vehicle. An output rod (72) is provided to press a friction pad (78) onto the disc rotor (42) so as to exert a braking force on the wheel. A brake motor (30,32) is provided to generate a rotating force in response to an electric signal. A gear mechanism (48,66) is provided to axially move the output rod (72) relative to the disc rotor (42) in accordance with the rotating force, such that the output rod (72) is moved toward the disc rotor (42) when the brake motor (30,32) rotates in a forward direction, and that the output rod (72) is separated from the disc rotor (42) when the brake motor (30,32) rotates in a reverse direction. A load detection unit (10,82) detects a load acting on an end of the output rod (72) opposite to a position where the output rod (72) presses the friction pad (78) onto the disc rotor (42). A motor deceleration unit (10) decreases the rate of rotation of the brake motor (30,32) when the load detected by the load detection unit (10,82) is above a reference level. <IMAGE></p> |
