PROBLEM TO BE SOLVED: To provide an auxiliary tool for moving the center of gravity for reducing burden on the user's legs and waist and for achieving kind and quick attendance and effective usage of work space in a place where the user receives and attends to customers, and works long hours while standing. SOLUTION: A waist plate A (1) with an adjuster is fitted to a rotating shaft (2) by a fixing tool (3) with a stopper (4) for expansion and contraction so as to join to a one-arm side frame (5) by using a repulsive material and to connect with a slide rail (6) fixed to a floor face so that the waist plate is adjusted and operated forward and backward. The stopper is operated on the slide rail when the center of gravity moves or load is applied. The slide rail freely moves when the load is zero. COPYRIGHT: (C)2007,JPO&INPIT
