が次式を満足することを特徴とする流量調整装置
。 Ｙ＝ＡＸ＋Ｒ 但し、Ａ＝−4/7〜−3/7 Ｒ＝０．４〜１．３５ Ｘ≦１．１，Ｙ≦１．１[Claims for Utility Model Registration] An outer cylinder having a fluid passage hole communicating with a fluid outlet and an inner cylinder having a fluid inflow hole communicating with a fluid inlet, the system having a fluid inlet that communicates with a fluid inlet, and which is configured to respond to the differential pressure of the fluid acting on the inner cylinder. By forming the inner cylinder to be movable within the outer cylinder via an elastic member, the opening area of the fluid passage hole formed in the outer cylinder is varied by the inner cylinder, and the fluid is discharged from the fluid inlet to the fluid outlet. In a flow rate regulating device that controls a constant amount, the outer cylinder and the inner cylinder are made of ceramics, and the average surface roughness of the inner circumferential surface of the outer cylinder is Raμm=X, and the outer circumference of the inner cylinder in sliding contact therewith. A flow rate adjusting device characterized in that the relationship between the average surface roughness of the surface Raμm=Y satisfies the following equation. Y=AX+R However, A=-4/7~-3/7 R=0.4~1.35 X≦1.1, Y≦1.1
