Patent ID: 7731315

Claim:
A refrigerator, comprising: a first body including an inner case, an outer case, and a urethane foam filled between the inner case and the outer case, a coupling hole formed through the inner case, a mounting member coupled to the coupling hole on a first outside of the inner case by a first end of the mounting member and provided with a fastening hole, the mounting member being fixed between the inner case and the outer case by the urethane foam when the urethane foam is filled, and a fastening member fastened to the fastening hole at a first inside of the inner case in a state of being coupled to an element to be installed in an interior of the inner case, to mount the element to the inner case, wherein the mounting member comprises a cover for covering the coupling hole at the first outside, the mounting member is threadedly coupled to the coupling hole, and wherein the cover is pressed and deformed in accordance with a thread-coupling of the mounting member to the coupling hole such that the cover comes into close contact with an outer surface of the inner case around the coupling hole, and wherein the mounting member comprises a second body including a front body and a rear body, the front body being coupled to the coupling hole, and wherein the cover is formed on an outer peripheral surface of the second body between the front body and the rear body such that the cover extends radially while being rearwardly convex, and the mounting member further comprises a plurality of spiral protrusions formed on an outer peripheral surface of the front body, each one of the plurality of spiral protrusions being spaced apart from one another in a circumferential direction of the front body, wherein the coupling hole comprises: a first hole portion forming a central portion of the coupling hole, the first hole portion having a shape corresponding to a cross-sectional shape of the front body portion, to receive the front body portion; and a plurality of second hole portions formed around the first hole portion, each one of the plurality of second hole portions having a shape corresponding to a cross-sectional shape of each one of the plurality of spiral protrusions, to receive each one of the plurality of spiral protrusions, wherein the refrigerator further comprises: a first rotation stopper formed on the outer peripheral surface apart from the plurality of spiral protrusions; and a second rotation stopper formed on an outer surface of the inner case around the coupling hole and protruded backward from the coupling hole such that the first and second rotation stoppers engage with each other to prevent the mounting member from rotating a predetermined angle or more.
