PURPOSE:To restrict a reduction in strength of an opening and enable a positive fixing of a filter member to an external member to be attained by a method wherein the external member having the opening of the filter member is provided with a reinforcing rib for dividing the opening and one filter member is provided with a groove guided by this reinforcing rib. CONSTITUTION:In an interior heat exchanging unit 1, if a filter member 20 is inserted in an opening 16 of an external member 3, a left filter 22 is inserted into a left opening 18 and a right filter 23 is inserted into a right opening 19, respectively and thereafter a fixing piece 24 is pushed up to cause these two filter members to be stored in the interior unit 1 at once. At this time, a reinforc ing rib 17 is fitted to the groove 21 of the filter member 20 and then the filter member 20 is inserted into the opening 16 while being guided. Under a condition in which the filter member 20 is fixed to the opening 16, the fixing piece 24 of the filter member 20 is exposed from the opening 16. Therefore, a hand is applied to the projecting part 25 of the fixing piece 24 to push it downward, resulting in that the filter member 20 can be pulled out of the opening 16. |
