PURPOSE:To hold only a joint part subjected to adjustment processing so as to be freely movable, to exactly detect a distortion of three axes, and to appropriately adjust the distortion by fixing the body of the spinal column side of the body axis, forming the body of the outside of the body axis so as to be movable and detecting a distortion of the body axis. CONSTITUTION:On both sides of the top part of a back rest frame 11, fixed bands 11A, 11B are provided successively, and also, its lower parts are provided successively on an ascending/ descending lever 13 through a bearing part 12, and a supporting cylinder into which a screw 1part 3A of the ascending/descending lever 13 is fitted and inserted is provided firmly on a base 17. Also, on the ascending/descending lever 13, a waist part seat 14 provided additionally with a tightening-up band 14A is disposed. A user is allowed to stand up in the direction toward a display panel 22 on the base 17, his back part is allowed to abut on the back rest frame 11, and also, the waist part is allowed to abut on the display part seat 13, as well, the upper arm base part is tightened and fixed to the back rest frame 11 by the fixed bands 11A, 11B, and the tightening-up band 14A is wound round the waist part of the user and tightened. By following up a tilting motion of the upper half of the body of the user, the back rest frame 11 is inclined to the left and inclined to the right, and the tilting direction and the tilting amount are detected by a front/rear axis detector 20, and displayed on a display panel 22. |
