PROBLEM TO BE SOLVED: To provide a sample fluid variable pressure reducing device resolving accumulation of sample fluid and reducing pressure of the sample fluid in a state so that the sample fluid can be accurately analyzed. SOLUTION: In a variable pressure reducing mechanism part 23, a base end of a pressure regulating pipe 24 is connected to a one end opening of a cylindrical casing 33, an internal space 34 is communicated with a pressure regulating hole 25, a slide member 35 is provided in the internal space 34, a base end of a core wire 26 is fixed to the slide member 35, a female screw part 35a is formed on the slide member 35, a male screw part 37a is formed on an outer circumferential face of a screw shaft 37 and it is screwed in the female screw part 35a, a one end of the screw shaft 37 is protruded outside the casing 33 in a piercing state from another end opening of the casing 33 positioned in an opposite side to the pressure regulating pipe 24, the opening is sealed by a shaft seal part 39, a sample fluid outlet 46 is opened in a casing 33 side face, a pressure of the sample fluid inputted from a sample fluid inlet 27 is reduced in the pressure regulating hole 25, the sample fluid is passed through the internal space 34, and the sample fluid is delivered from the sample fluid outlet 46.
