1. A work comfort evaluating device for evaluating a level of comfort of work by measuring myoelectric potentials of plural muscles when the work is done by antagonistic activities of said muscles, said work comfort evaluating device comprising:

  • a pair of detecting sensors for sensing myoelectric potentials of said muscles generated through muscular activities of a human body at a time of work;

    an amplifier for amplifying said myoelectric potentials sensed by said detection sensor;

    a signal processing part for calculating a synchronous contraction intensity of said muscles by using myoelectric potential waveforms of said amplified myoelectric potentials;

    a work load intensity calculating part for calculating a level of a work load intensity in said work imparting load to said muscles with a timing of the generation of said synchronous contraction intensity; and

    an evaluation part for evaluating a level of comfort of said work by normalizing said synchronous contraction intensity by the level of said work load intensity calculated.
