Zusammenfassung:	PURPOSE:To improve thermal insulation properties in the range from a low temperature to a high temperature, by arranging two cylinders, whose diameters are different, in the superposed coaxial circles state, and integrally molding the adjacent cylinders in a unified body at the central parts of the cylinders. CONSTITUTION:Reinforcing fiber impregnated with resin is wound around a rotary mandrel 14 in the state that an auxiliary mandrel 15 and a bolt 16 are removed. When molding is finished until a part corresponding to an inner cylinder, the mandrel is interrupted and the auxiliary mandrel 15 is fixed to the mandrel 14 by using the bolt 16. By rotating again the mandrel 14 the reinforcing fiber impregnated with resin is wound around the central part and the auxiliary mandrel 15, thus forming an outer cylinder part 1 and a central part 3. These are left to stand for a specified time and then the bolt is removed and the auxiliary mandrel 15 is pulled out. Thereby a double cylinder heat insulating retainer which is connected by integral molding at the central part can be obtained, so that a heat insulating retainer for a low temperature vessel which retainer has excellent heat insulating properties can be obtained.
