Abstract: PURPOSE:To make it impossible to impose bending stresses on clear sheet glasses and to prevent their damages by fixing the clear sheet glasses to a fixing frame through an elastic seal ring placed on the circumferential edge of an interval adjusting spacer. CONSTITUTION:Interval adjusting spacers 3 are respectively inserted between the circumferential edges of a plurality of clear sheet glasses 1... to form heat insulating enclosed spaces 4, the circumferential edges are fixed with a fixing frame 2, and a door body of a refrigerator provided with a clear window is made. A circular seal ring 10 having elasticity is loaded on the peripheral surface of the clear sheet glasses 1... by which the spacers 3 of the door body are held, and the clear sheet glasses 1... are fixed to the fixing frame 2 through the ring. According to the constitution, a warp caused by temperature difference between the inside and outside of the refrigerator of the door body can be absorbed by elasticity of the circuit seal ring 10.
