Claims

[Scope of utility model registration request]

An orifice body 1 is formed by press-forming a thin metal plate into a cylinder shape with a bottom, and has a throttle hole 5 at the bottom for regulating the flow rate of fluid, and a housing 2 is molded from an elastic synthetic resin material. a diameter larger than the fluid passage 4, communicating with the fluid passage 4 and forming a stepped hole;
In the fluid flow rate regulating device that is press-fitted into the press-fit hole 3 of the orifice body 1, the press-fit hole 3 extends from the shoulder portion 3-1 formed in the communicating portion with the fluid passage 4 toward the opening end. A press-fit hole in an orifice body that is a tapered hole with a smaller diameter.
