An oil cooler is provided to prevent crevice corrosion and galvanic corrosion by being sealed by the shape and the structure of components as the mounting surfaces of a flare nut and a hex nut functions as a stopper. An oil cooler comprises a main body(110) and an inlet/outlet port(120). The inlet/outlet port comprises a pipe(121), a boss(124), a flare nut(122) and a hex nut(123). The pipe circulates the oil to the main body. The boss connects the pipe to the main body. The flare nut joins the boss and the pipe. The hex nut joins the boss and a radiator tank(210). In the boss and the flare nut, a sealing joint part and a sealing part are formed. Screw-assembling portions of the flare nut and the boss are sealed from outside through the sealing joint part and the sealing part. |
