1. A hydraulic block of an electronic braking device for vehicles, comprising:
a first input port for receiving brake oil from a master cylinder;
a first output port for discharging the brake oil to a wheel brake;
a first inlet valve port for accommodating a first inlet valve disposed on a first inlet flow path connecting the first input port to the first output port; and
a first outlet valve port for accommodating a first outlet valve disposed on a first outlet flow path configured to depressurize the brake oil,
wherein the first outlet flow path is configured to pressurize the first outlet valve in an axial direction of a first plunger mounted inside the first outlet valve and to deliver the brake oil to the first outlet valve,
the first outlet flow path includes a first linear-decompression flow path,
the first linear-decompression flow path being configured to bypass the brake oil delivered from the first input port in a vertically downward direction, and to supply the brake oil to the first outlet valve in a direction parallel to the first outlet valve port,
the first linear-decompression flow path is vertically connected with the first outlet flow path to receive the brake oil, and
the first linear-decompression flow path includes at least two perpendicularly-bent portions after the brake oil passes a connection point of the first linear-decompression flow path with the first outlet flow path and before the brake oil reaches the first outlet valve port.
