<p>PROBLEM TO BE SOLVED: To move a hanger to a position where medical examination is easily performed and to facilitate the pure movement of its position and fixing. SOLUTION: A hanger 4 is fixed to a slide body 8 which is externally inserted freely slidably along a slide shaft 6 and freely rotatably around the axial center of the slide shaft 6 as a center through a control plate 9 for restricting the range of rotation by bringing it into contact with the back surface of a table and a rubber sheet 11 is stuck on the contact face of the control plate 9 to control deviation in the axial direction. The front of the hanger 4 is ordinarily rotated thereby downward by the wt. of a hooked instrument 3 and the control plate 9 is brought into contact with the back surface of the table 1 through the rubber sheet to control deviation caused by frictional resistance of the rubber sheet 11 and, when it is moved, the rubber sheet 11 is separated from the back surface of the table by taking up the front of the hanger 4 to release the frictional resistance and to make movement possible.</p> |
