PROBLEM TO BE SOLVED: To provide a heat insulation material structure of a hot water storage tank capable of improving the assemble performance of a heat insulation material and capable of reducing manufacturing costs by omitting a special member for assembling.SOLUTION: A heat insulation material 1 covering the periphery of a cylindrical hot water storage tank T is a molding material formed of a synthetic resin foam. The material includes a top member 2 covering an upper end side of the hot water storage tank T and first and second vertically-divided members 3 and 4 covering halves of the outside periphery of a body Tb of the hot water storage tank T. The first and second vertically-divided members 3 and 4 are configured to cover a part of a bottom Tc of the hot water storage tank T. An engagement structure 10 is provided for connecting and fixing a lower part of the first vertically-divided member 3 and a lower part of the second vertically-divided member 4. After the lower part of the first vertically-divided member 3 and the lower part of the second vertically-divided member 4 are engaged with each other so as to cover the body Tc of the hot water storage tank T by the engagement structure 10, the top member 2 is externally fit to an upper end of the first vertically-divided member 3 and an upper end of the second vertically-divided member 4, and thus, the heat insulation material 1 is fixed. |
