<P>PROBLEM TO BE SOLVED: To provide a gas sealing structure capable of sufficiently sealing while absorbing a difference in thermal expansion between a wall part and a high temperature pipe. <P>SOLUTION: In this gas sealing structure for sealing between the wall part 1 and the high temperature pipe 2 passed through the wall part 1, a seal member is filled between an inner wall of a through hole 1a formed in the wall part 1 and an outer wall of the high temperature pipe 2 passed through the the through hole 1a. The seal member is formed by holding powder body 4 between heat resistant members 3 installed at least double in the longitudinal direction of the high temperature pipe 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
