The present invention relates to a box with a variable lower part, and, more specifically, to a box with a variable lower part, capable of easily loading articles therein by changing the width of the lower part thereof, and of being vertically stacked. The box with a variable lower part comprises an upper frame with opened upper and lower parts; a side wall formed by being extended from the lower part of the upper frame toward the lower side; multiple variable units consisting of supporting plates bent and formed from the lower end of the side wall toward the inside thereof; a bottom plate arranged on the supporting plate; a connection plate having one end connected to the variable unit and the other end connected to the bottom plate; and a locking unit fixing the bottom plate not to be vertically moved. Cutout parts are formed among the multiple variable units. The height of the connection between the other end of the connection plate, and the bottom plate is formed to be higher than the height of the connection between the one end of the connection plate and the variable unit when the width of the lower part of the variable unit. The locking unit fixes the bottom unit when the descending bottom unit changes the variable units mutually connected by the connection plate to increase the width of the lower part of the variable unit. |
