Abstract
A flow rate control apparatus includes a valve mechanism capable of controlling a flow rate of a pressure fluid that flows from a second port to a first port. Second stopper walls are formed on a seating section of a needle valve constituting the valve mechanism and which is capable of advancing and retracting in an axial direction. In addition, in a total valve-closed state when the seating section of the needle valve is seated on a seat of a first body, the second stopper walls come into abutment and are stopped in a circumferential direction of the needle valve with respect to first stopper walls of the first body.
