Disclosed therein is to an icebox, which has volume varying means so as to selectively vary a storage space of the icebox for storing various food supplies and to simultaneously store various portable means and household items to thereby prevent convenience in use. The icebox includes: an icebox body having a bottom and side walls, which are filled with insulating material, and a storing part opened at one side for storing foods therein; a cover for selectively opening and closing the opened side of the icebox body, the cover having a receiving part; a capacity varying part interposed between the icebox body and the cover and slidably joined to the storing part so as to vary the capacity of the storing part. Because the capacity of the storing part of the icebox is selectively varied, the icebox enables the user to utilize the space of the storing part in various ways, can accommodate various kinds of food supplies and household items, and is convenient in going long distance.

1. An icebox comprising: an icebox body (100) having a bottom (101) and side walls (103), which are filled with insulating material (10), and a storing part (107) opened at one side for storing foods within the storing part; a cover (300) for selectively opening and closing the opened side of the icebox body (100), the cover (300) having a receiving part (310);a capacity varying part (400) interposed between the icebox body (100) and the cover (300) and slidably joined to the storing part (107) so as to vary the capacity of the storing part (107), the capacity varying part (400) having an inside communicating with the storing part (107) of the icebox body (100) and including: a seating portion (410) seated on an upper face of the side walls (103) of the icebox body (100); and lifting frames (420) bent and extending from the seating portion (410) toward the storing part (107) and having side wall receiving portions (423) for receiving the side walls (103) when they are slidably joined to the icebox body (100); andat least one fastener (430) disposed on an outer circumferential surface of the lifting frames (420) of the capacity varying part (400), the at least one fastener protruding outwardly and having a plurality of fastening slots (433),wherein separation portions (109) are formed along the upper faces of the side walls (103) of the icebox body (100), and have a predetermined depth toward the bottom (101) so that the lifting frames (420) of the capacity varying part (400) can be slidably joined to the side walls,wherein a guide groove (120) is formed on the side walls (103) at a position corresponding to each at least one fastener (430), and communicates with the separation portions (109) so that the at least one fastener (430) is slidably inserted when the lifting frames (420) is joined, andwherein a position determining pin (130) is slidably arranged in the guide groove (120) and fit into the fastening slots (433) of the fastener (430), the position determining pin sliding along the guide groove (120) to maintain a position of the lifting frames (420). 2. The icebox according to claim 1, wherein the side walls (103) comprise: a stepped jaw (105) formed on an inner circumferential surface of an upper portion of the sidewalls and the stepped jaw extending in a direction of the storing part (107); and a separation preventing jaw (425) formed on the an circumferential surface of a lower portion of the sidewalls and the separation preventing jaw retained to the stepped jaw (105) of the side walls (103) to prevent a separation of the lifting frames (420). 3. The icebox according to claim 1, wherein the receiving part (310) of the cover (300) comprises: a tray (330) having a predetermined depth for receiving various kinds of food supplies and household items within the tray; andan auxiliary cover (320) disposed on an upper portion of the receiving part (310) for selectively opening and closing the receiving part (310). 4. The icebox according to claim 3, wherein the tray (330) further comprises a cup receiving recess (333) having a predetermined depth for receiving cups. 5. The icebox according to claim 1, wherein the cover (300) further comprises a grasping recess (300a) formed on an outer circumferential surface of the cover for varying the capacity varying part (400). 6. The icebox according to claim 1, wherein the icebox body (100) further comprises: inner bail handles (210) respectively joined to outer faces of the side walls (103) through fixing members (30); andouter bail handles (250) joined to the fixing members (30) and having an extendable length. 7. The icebox according to claim 6, wherein the outer bail handles (250) comprise: a rotational bar (220) having a through hole (223) formed in an outer circumferential surface and a first end rotatably joined to the fixing members (30);elastic member (230) made with an elastic plate and having a central protrusion (233), the elastic member (230) being disposed on an inner circumferential surface of the rotational bar (220) so that the protrusion (233) is fit into the through hole (223); anda variable bar (240) slidably joined to a second end of the rotational bar (220) and having a plurality of individually spaced position fixing holes (243) formed on an outer circumferential surface of the variable bar at predetermined intervals.
