Abstract: A moving shelf assembly having moving shelf main bodies capable of moving by wheels attached to the lower portion and whose motion is guided by rails built on the top portion, stopper parts capable of moving up and down attached to the moving shelf main bodies, and height adjusting parts which adjust the height at which the stopper parts are attached in relation to the moving shelf main bodies, and wherein plugs capable of being inserted into and pulled out of guiding grooves open on the lower surface of the rails protrude upwards from the stopper parts, and the height at which the stopper part is attached in relation to the moving shelf main body is adjusted by the height adjusting part, and wherein the moving shelf main body is separated from the rails when the plugs, which are inserted in the guiding grooves, are pulled out of the guiding grooves and is then capable of moving freely by the wheels.
