Claims

[Scope of utility model registration request]

In a pipe penetration part where a pipe passes through a body that forms an exhaust gas passage and is provided with a heat insulating material inside, an expandable plate provided between one side of the body and the pipe, and a retractable plate provided on the other side of the body. A seal ring whose inner diameter is approximately equal to the outer diameter of the tube and whose outer diameter is larger than the diameter of the tube through hole is slidably inserted into the outside of the tube, and both sides of the A seal ring are slidably held together with the side surfaces of the body. An airtight bulkhead comprising a B seal ring and a C seal ring.
