PURPOSE: A bellows pipe structure is provided to increase durability by permitting the fluid filling the bellows pipe to absorb impacts applied from an external source. CONSTITUTION: A bellows pipe structure comprises an outer wall(10) on which a plurality of steel members(11) are coupled into a zigzag manner in such a manner that the outer wall is contractible/extendable by the movement of the steel members; an inner wall(12) arranged to have a predetermined gap from the outer wall; a plurality of diaphragms interposed between the outer wall and the inner wall; an orifice penetrating through the center of the diaphragms; and a fluid(13) filling the space formed between the outer wall and the inner wall, wherein the fluid flows to the place having a low pressure through the orifice in correspondence to the pressure applied in accordance with the movement of the outer wall.
