Abstract
An assembly and inspection cart for precision equipment includes a frame that has three support portions to support the precision equipment at three points, air float devices attached to the frame at three positions, a rubber roller and a motor that are provided so as to be freely lifted and lowered with respect to the frame, and an air cylinder that lifts and lowers the rubber roller. The air float device floats the frame together with the precision equipment and forms an air layer between the frame and a floor surface. The rubber roller is arranged at a center of the three air float devices and is configured so as to press against the floor with a predetermined force when lowered by the air cylinder in a state where the frame is floated.
