A thermomechanical analyzer capable of performing, in addition to thermomechanical measurement, thermogravimetry of a sample of several grams or more only by switching parts of the analyzer. A thermomechanical analyzer has a heating furnace, a temperature detector for detecting temperature of the sample that is placed within the heating furnace, an attachable/detachable detecting rod and a sample holding member, wherein the sample is held between the detecting rod and the sample holding member. A load applying instrument applies an external force to the sample via the detecting rod. A displacement detector detects displacement of the detecting rod relative to the sample holding member. The thermomechanical analyzer is provided with a control computing apparatus for adjusting an output from the load applying instrument to bring an output from the displacement detector closer to a fixed value. The detecting rod and the sample holding member in the thermomechanical analyzer may be replaced respectively with a sample container and a container holding member. A recording device records output from the temperature detector and the load applying instrument.
