PURPOSE: A foaming guide installation structure is provided to improve the heat insulation performance by configuring a foamable structure and to drastically improve the usage efficiency. CONSTITUTION: An outer case forms an outer shape of a main body. An inner case is arranged to be separated from the outer case. A foaming space is positioned in a space between the outer case and the inner case, and admits a foaming agent. An injection hole (400) injects the foaming agent into the foaming space. A guide part (500) is connected to the injection hole, and guides the foaming direction of the foaming agent. The guide part has more than two branched tubes.
