Abstract
A downstream side fin group is formed by a plurality of fins. Among these fins, end fins positioned at both ends in an arranging direction are arranged near second wall portions. Each end fin has an extension portion which is bent at upstream end thereof and extends toward the corresponding second wall portion. A space is provided near each second wall portion in the ventilation passage. Each space is closed by the corresponding extension portion at a time when the corresponding end fin is arranged at a maximum inclined position at which the end fin is most away from the second wall portion, and the extension portion enters the space at a time when the end fin is arranged at a different position from the maximum inclined position.
