This electric braking device uses drive torque of an electric motor (MTR) to push a friction member against a rotating member secured to a vehicle wheel and produce braking torque in the vehicle wheel. This device comprises a body power source (BBD) for electric motor power supply secured to a body of the vehicle, and a vehicle wheel power source (BWH) for electric motor power supply secured to the vehicle wheel. The body power source (BBD) supplies power to the vehicle wheel power source (BWH) via a first electric path (PBD+PWH), and the vehicle wheel power source (BWH) supplies power to the electric motor (MTR) via a second electric path (PWH). When braking torque is produced in the vehicle wheel, the electric motor (MTR) is normally driven using the vehicle wheel power source (BWH). An electric braking device is thereby provided in which a power line electrically connecting the body side and the vehicle wheel side bends readily. |
