In the directional flow control valve that applies an axial force to move toward a position where the inlet port 5 and the outlet port 6 are communicated, the spring receiver 10 is brought into contact with the end 3a of the spool 3,
A directional flow rate control valve characterized in that a gap S1 is formed between the spring receiver 10 and the end surface 1a of the valve body 1 when the spool 3 is in the neutral position.
