する。 In the present invention, a cylindrical member made of a plurality of cylinders of different diameters slidably connected and configured to be expandable and contractible is inserted into the sample tube insertion port of the cavity resonator, and the innermost cylinder of the cylindrical member is inserted into the sample tube insertion port of the cavity resonator. It is characterized by being designed to hold sample tubes. Hereinafter, the present invention will be explained in detail using the drawings.

該ホルダ７は挿入口４へ挿入される。 FIG. 2 is a sectional view showing an example of a sample holder embodying the present invention, and the same components as in FIG. 1 are given the same numbers. In FIG. 2, the sample tube holder 7 has a two-stage structure having an outer tube 8 and an inner tube 9, and the inner tube 9 slides within the outer tube 8 and is expandable and retractable. 10 is a stopper. Then, with the sample tube 2 held by the inner tube 9, the holder 7 is inserted into the insertion port 4 until the flange 11 provided at the top of the outer tube 8 hits.

て小さくなる。 Figure 3 shows a holder having the above-mentioned configuration, (a)
A state in which the inner cylinder 9 is pulled out by the length thereof and (b) a state in which the holder 7 is pulled out by the fully extended length are shown, respectively. In the conventional example shown in FIG. 1, the holder 3 has already come out of the cavity resonator 1 in the state shown in FIG. I came into contact with. On the other hand, in the present invention, since the outer cylinder 8 is fitted into the insertion port in this state, the sample tube does not wobble, and the sample tube does not move until the outer cylinder 8 comes out in the state shown in Fig. 3b. There is a possibility of wobbling, but by this time most of the sample tube has already been extracted from the cavity resonator, and the tolerance for wobbling is extremely large compared to the conventional example. Therefore, the possibility of inconveniences such as sample tube breakage is extremely reduced.
尚、上記実施例では試料管ホルダ７を２段構造

し得る。 In the above embodiment, the sample tube holder 7 has a two-stage structure, but if the number of stages is further increased, the length of the holder when extended increases. This can further reduce the possibility of inconveniences such as damage occurring.
