PROBLEM TO BE SOLVED: To provide a hydraulic device for obtaining a NVH characteristic of a vehicle having reduced noise and oscillation.SOLUTION: A hydraulic device 26 for a vehicle brake device equipped with a hydraulic pump 14 for pump supply of a hydraulic fluid flow into a damper pipe line 18, in which a damper 22 is connected to the damper pipe line 18 in a fluid guide type. In teh hydraulic device, a bypass line 28 bypassing the damper 22, and a bypass valve 30, which so guides the hydraulic fluid flow such that th fluid flow selectively passes through the damper pipe line 18 or the bypass line 28, are provided. |
