PROBLEM TO BE SOLVED: To provide a hydraulic electric braking device combined with an accumulator, capable of effectively utilizing the residual oil pressure. SOLUTION: In this hydraulic electric braking device operated by the discharged oil pressure of an electric pump 1, a high-pressure reservoir 10 and a low-pressure reservoir 11 are mounted in the electric braking device, a hydraulic cylinder 31 in the electric braking device is connected to the high-pressure reservoir 10 and the low-pressure reservoir 11 through a solenoid valve, and the residual oil pressure in releasing the brake is divided to be accumulated to the high-pressure reservoir and the low-pressure reservoir on the basis of a predetermined pressure as the boundary. |
