Hydraulic control valve device effectively reducing NVH effect. The hydraulic control valve device comprises the cap member (39) at the distal end of the smaller diameter portion (32b) of the magnet core and a throttled channel (39b) between the cap member (39) and the bottom portion (43a) of the outer piston (43), wherein fluid flow is switched to the throttled channel (39b) when the outer piston slides in the direction to close the communication hole (39a) of the bottom portion (39) of the smaller diameter portion (32b) by the hydraulic pressure difference between the hydraulic pressure at the master cylinder side and the wheel cylinder side.
