PROBLEM TO BE SOLVED: To prevent a core part from being damaged by collision of an end of a shroud with the core part. SOLUTION: A crevice size X of a stopper 311b and a side plate 130 is made smaller than a crevice size Y of parts (a simple flange 311c) other than the stopper 311b in the flange part 311 and a core 110. Therefore, the stopper 311b collides with the side plate 130, so as not to relatively displace other parts (the simple flange 311c). A core 110 (especially a tube 111) can be prevented from being damaged, without securing an enough crevice between a shroud 310 and radiator 100 (the core 110).
