PURPOSE:To obtain the functions of two kinds of material with different elasticity by the use of one kind of material in the condition that the hollow part of an insulating material carries out cushion action at the time of attaching an air filter by a method wherein a part of a partition member forming a passage for suction air at one side and a passage for an ejected air at the other side is formed into a letter U shape and the insulating material attached on the passage for ejected air is attached in one body to constitute a hollow part at the U-shaped part. CONSTITUTION:A partition member 6 faces a suction port 4 at one side and an ejecting port 5 at the other side and is equipped with a letter U-shaped support part for an air filter 3. At the air ejecting side an insulating material 9 for preventing the generation of dew condensation is attached in one body to constitute a hollow 10 at the U-shaped part. When the tip part 9a of the material 9 is compressed at the time of attaching the filter 3, the hollow 10 shrinks easily and the filter 3 is put in the U-shaped part of the member 6 and the cushion action is carried out by the constitution of the hollow 10 formed by the part 9a. The insulating material 9 and the tip part 9a which are constituted separately by two kinds of material in the past can be made by one kind of material and formed into one body. |
