Abstract
A double pipe connection structure includes a joint member and a double pipe having an inner pipe and an outer pipe coaxially disposed therein. Further, the double pipe connection structure includes a supporting rib formed integrally therewith in an axial direction, wherein the supporting rib connects the inner pipe to the outer pipe. Further, the joint member includes a first hole into which the outer pipe is inserted and a second hole into which the inner pipe is inserted, wherein the second hole has a diameter that is smaller than a diameter of the first hole, and wherein the first and second holes are bored to be aligned in an axial direction. Moreover, in the joint member, a first-pressure connecting hole communicates with the first hold and a second-pressure connecting hole communicates with the second hole, such that a pressure in the first-pressure connecting hole is lower than a pressure in the second-pressure connecting hole.
