<p>PURPOSE: To easily draw the backbone and the line of the backbone in a home by a healthy person and a person with light subjective symptom of lumbago by mounting a moving mechanism on a base plate so as to increase/decrease distance between an upper half body fixing board and a lower half body fixing board and providing a traction force generating mechanism between the lower half body fixing board and the base plate. CONSTITUTION: The upper half body fixing board 2 equipped with an upper half body fixing belt 4 is mounted on the base plate 1, and the lower half body fixing board 3 equipped with a lower half body fixing belt 5 is mounted by providing the moving mechanism 7 so as to increase/decrease the distance from the upper half body fixing board 2. A guide is mounted to prevent floating and meandering when the lower half body fixing board 3 is moved from occurring, and a running face plate to reinforce a running face is mounted. Moreover, a traction force generator to draw the lower half body fixing board 3 is mounted. The output of the torque motor of the traction force generator is controlled by an operation controller at hand, and the lower half body fixing board 3 is drawn at a slow speed by a reduction gear to eliminate shock on the waist.</p> |
