To provide an antinoise structure for a flow rate control valve capable of reducing noise caused by vibration of a component connected to an upstream side and/or a downstream side of the flow rate control valve.
The flow rate control valve 12 is connected between a surge tank 14 constituting a fuel gas supply passage and a support body 16, and controls a flow rate of fuel gas. A sleeve member 32 and a filter member 43 damping pressure pulsation of the fuel gas when passing the fuel gas are provided in the surge tank 14. A sleeve member 60 damping the pressure pulsation of the fuel gas when passing the fuel gas is provided in the support body 16. The sleeve member 32, the filter member 43 and the sleeve member 60 are porous cylindrical members through which the fuel gas (fluid) can pass in a radial direction.
