Abstract

The present invention relates to a waste basket. While a waste bag left on top of a floor plate, the rest of unit bodies, other than a unit body directly connected to the floor plate, are descended toward the floor plate to expose the waste bag to the outside. Otherwise, the present invention is capable of exposing the waste bag to the outside by ascending a body, while the waste bag is left on top of the floor plate. Therefore, a user does not need to lift up and pull out a heavy waste bag, but to pull the waste bag exposed to the outside toward side direction or toward the front direction, thus pulling out the waste bag using small strength without force toward the gravitational direction.
