PURPOSE:To enable the bending direction of a bending pipe to be easily changed by providing a fitting part between a nipple connected to the oil duct of an oil cooler and the bending pipe inserted into the nipple as well as mounting a spring and a sealing member at the fitting part. CONSTITUTION:A lower tank 5 of a radiator for the automobile is provided therein with a double tube type oil cooler 10 which has a piping 11 forming an oil duct, the circumference of which is fitted integrally with a nipple 12. Further, the nipple 12 is formed into a cylindrical shape having an interior surface with a step, the circumference of which is fitted integrally with a flange 13. Meantime, a bending pipe 1 fitted to the nipple 12 is provided with a flange 18 opposing the step 19. And, a helical compression spring 20 is installed in a compressed state between the flange 18 and the step 19. Besides, a holding groove 21 is formed on the interior surface of the nipple 12, in which an O ring 22 is mounted for sealing the pipe 1 and the nipple 12. |
