PURPOSE: To surely absorb tube thermal expansion and contraction caused by the temperature change of cold water in a radiator constructed by interconnecting both end parts of upper and lower tanks placed opposite to each other by a side support. CONSTITUTION: A core part having a tube and a fin, alternately arranged, is formed between an upper tank 31 and a lower tank arranged oppositely to each other with a space in the upper and lower directions. Both end parts of the upper and lower tanks 31, and so on are connected to each other by a side support 39 and a tank side bracket 31a with a through-hole 31b formed in both end parts of at least the upper tank 31. Further, a support side bracket 39a inserted into the through-hole 31b is formed in the end part of the side support 39 and an elastic body 41 is arranged between the upper surface of the through-hole 31b of the tank side bracket 31a and the upper surface of the support side bracket 39a. |
