<P>PROBLEM TO BE SOLVED: To provide a compact and highly useful vibration health machine that is very safe since it creates even a large amplitude of vibrations by repeating smooth up and down movements. <P>SOLUTION: The vibration health machine is characterized in that a foot rest is pivoted and swings on a base board, by which the stand's left and right ends move up and down via a support shaft arranged at about the lateral center of the foot stand and nearly horizontally extending forward and backward, that a driving means is provided with an up-and-down moving part arranged near either leftward or rightward from the support shaft, and a driving tool for moving this up-and-down moving part, that an eccentric portion of a rotary shaft rotated by the driving tool moves the foot rest up and down via a connecting rod, and that the foot rest repeats seesaw movements of its left and right ends centering along the support shaft. <P>COPYRIGHT: (C)2008,JPO&INPIT |
