Abstract: The present invention provides a double pipe connection structure where, in a distal end portion of an outer pipe (42) of a double pipe (4), an outer pipe expanded part (42a) detached from a supporting rib (43) and having a diameter expanded more than that of a general part of the outer pipe (42) is formed; the outer pipe (42) is coupled with a joint member (5) by caulking a collar part (51c) at a periphery of an open end portion of a large diameter hole (52) of the joint member (5) in a state that an inner pipe end portion (41a) of the double pipe (4) is inserted into a small diameter hole (53) while an inner pipe side O-ring (61) mounted on an outer periphery thereof is press-contacted with an inner periphery of the small diameter hole (53) of the joint member (5); and the outer pipe expanded part (42a) is inserted into the large diameter hole (52) while an outer pipe side O-ring (62) mounted on an outer periphery thereof is press-contacted with an inner periphery of the large diameter hole (52) of the joint member (5).
