<P>PROBLEM TO BE SOLVED: To provide a double glazing panel improved so as to absorb a pressure difference produced between the internal pressure of a heat insulation layer space and the atmosphere. <P>SOLUTION: The double glazing panel forming an enclosed heat insulation layer space between a plurality of plate glasses has: a vacant chamber communicating with the atmosphere demarcated at a position adjacent to the end edge part of the plurality of the plate glasses; and a partition wall deformed in response to the fluctuation of an atmospheric pressure to be partitioned between the vacant chamber and the heat insulation layer space. Thereby when the internal pressure of the vacant chamber is increased and decreased in response to the fluctuation of the atmosphere, the partition wall is deformed to balance the internal pressure of the heat insulation layer space with the atmosphere. In addition, when the density of air sealed in the heat insulation layer space fluctuates, in this case, the partition wall is also deformed to balance the internal pressure of the heat insulation layer space with the atmosphere. <P>COPYRIGHT: (C)2004,JPO |
