PURPOSE:To make the change of heat insulating members easier and improve heat insulating capacity by securing the heat insulating members to an outer plate by use of securing members inserted in a plurality of grooves provided in the surface of the outer plate, the securing members being made of rubber or resin having heat insulating and elastic properties. CONSTITUTION:An outer plate 1 is provided with a plurality of grooves 1a, and securing members 3 made of rubber or resin having heat insulating and elastic properties are inserted in the grooves 1a through heat insulating members 2 attached along the surface of the outer plate 1 and the grooves 1a. The heat insulating members can easily be mounted, the securing members can easily be removed. The area securing the heat insulating members becomes greater so that the outer plate and the heat insulating members are secured to each other more firmly, heat insulating capacity is improved by preventing air from being trapped between the outer plate and the heat insulating members. The securing members made of rubber or plastic do not have possibilities of coming off by reason of corrosion which can occur when they have contacted with water. |
