1. A load body state judging device to judge a state of a load body by analyzing signal data obtained by a displacement signal collection sensor which can collect a living body displacement signal of the load body supported by a load body supporting means, comprising:

  • an average displacement inclination operating means to divide an original waveform of signal data obtained by said displacement signal collection sensor into each prescribed time range and determine a rate of change of the signal data in the prescribed time range as a average displacement inclination;

    an emphasis displacement inclination operating means to determine an emphasis displacement inclination by slide-calculating a rate of change of an average displacement inclination for each prescribed sampling time at a prescribed slide lap rate over prescribed number of times from time series data of said average displacement inclination so that the time series data of the emphasis displacement inclination is obtained; and

    a state judging means to judge a load body state from the time series data of the emphasis displacement inclination obtained by said emphasis displacement inclination operating means.
