PURPOSE: To provide an inlet valve structural body with switching valve in compactness wherein ensuring a pressure increasing amount can be attained by reducing noise and pulsation.

CONSTITUTION: In an inlet valve body structure 20 with switching valve used in a vehicle use brake control device performing antilock control or traction control by having a main fluid pressure flow path via a master cylinder 12, inlet valve 21 and a wheel cylinder of a wheel and having a return flow path 33 returned to the main fluid pressure flow path via a wheel cylinder 30, outlet valve 31 and a pump 35, the inlet valve body structure 20 with switching valve has a function of inlet and switching valves, to arrange the switching valve in series to the inlet valve. In the inlet valve body structure 20 with switching valve, switching is performed between an opening condition and a throttling condition by a differential pressure of the main fluid pressure flow path between a side of the master cylinder 12 and a side of the wheel cylinder 30.
