PROBLEM TO BE SOLVED: To provide a core wire insertion type sample liquid decompression apparatus which can accurately and smoothly shuttle a driven shaft axially that advances and retreats a core wire, can prevent forces from orthogonally acting on the axis of the driven shaft, and can be made small by simplifying its structure. SOLUTION: In the sample liquid decompression apparatus having a drive shaft 22, the driven shaft 24 being disposed in coaxial alignment with the drive shaft, and the core wires 32, 34 advancing and retreating in accordance with the rotation of the driven shaft, a rotation transmitting mechanism 26 which transmits the rotational motion of the drive shaft to the driven shaft, is composed of a shaft coupling 44 which has a cut section 48 on its edge side and rotates in conjunction with the rotation of the drive shaft, and a cylindrical rotator 46 which is mounted on the edge section of the driven shaft so that its axis is perpendicular to that of the driven shaft and is inserted into the cut section of the shaft coupling while a gap is ensured in relation to its wall section and which rotates in conjunction with the rotation of the shaft coupling in order to rotate the driven shaft.
