PURPOSE: To dispense with a dedicated moving bogie of a revolving chair by providing floating mobile casters protrudable from openings of a revolving chair grounding base having multiple openings. ;CONSTITUTION: When the drive switch of mobile cylinders 118 is turned on to increase the pressure of the cylinders 118, the pistons 154 of the mobile cylinders 118 are extended in the length direction, and L-shaped arms 151 are rotated clockwise or counterclockwise centering on fulcrums 153. The L-shaped arms 151 are rotated downward, rollers 119 fitted to the L-shaped arms 151 are protruded from the openings 112 of a revolving chair grounding base 111, and a revolving chair is made movable. When the drive switch is turned in the direction to decrease the pressure of the mobile cylinders 118, the L-shaped arms 151 are rotated in the opposite direction, and the rollers 119 are stored in the openings 112. The revolving chair is made immovable by its weight and the friction of a bottom section. The movement and fixing of the revolving chair are facilitated.;COPYRIGHT: (C)1993,JPO&Japio
