置。 A supply passage for supplying pressure fluid, a bypass passage for releasing a portion of this supply fluid to the low pressure side, and a valve storage hole into which the supply passage and the bypass passage open are formed in the housing. The flow control device includes a spool valve that controls opening and closing of a bypass passage by sliding in the axial direction, and a union that closes one end of the valve housing hole, the union of the valve housing hole being attached to the tip of the union. A fluid control protrusion is formed that protrudes to the vicinity of the side opening edge and suppresses the supply fluid from flowing into the spool valve side between the outer periphery of the protrusion and the opening edge, and a notch is formed on the outer periphery of the fluid control protrusion. . A flow rate control device characterized in that an introduction path is formed between the notch and the valve storage hole to allow the working fluid from the supply path to flow uniformly into the spool valve side in the circumferential direction.
