<p><P>PROBLEM TO BE SOLVED: To connect exhaust pipes to be relatively oscillatory; and to connect them also to the pipe axial direction to be relatively movable without damaging sealing performance. <P>SOLUTION: Connection parts of a pipe 200 and a pipe 300 are sealed while the pipes 200 and 300 are elastically energized by a coil spring 501 to a direction approaching to each other and the pipes 200 and 300 are elastically energized so as to be separated from each other by a truss-like spring 601. The relative oscillation of the pipes 200 and 300 is permitted by oscillating deformation of the spring 601, and the relative movement of the pipes 200 and 300 in the pipe axial direction is permitted by extending deformation of springs 501 and 601. Even when the pipes 200 and 300 are moved to the direction relatively separated from each other, the shape of the spring 601 is returned so as to absorb the movement amount, and thereby, the sealing performance is not damaged. The spring 601 is autonomously positioned in accordance with shapes of fixing flanges 210 and 310. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
