<p>PROBLEM TO BE SOLVED: To secure high airtightness by constituting a sealing member of a ring sealing main body with an engagement groove formed on its outer peripheral part and a plural number of narrow paper tablet type sheet pieces to be deformed along an outer peripheral part of an article to be passed through passing through a sealing main body inner peripheral part. SOLUTION: A part between a through hole 1a and a piping 3 is sealed with a sealing member 2 installed on the through hole 1a. The sealing member 2 is constituted of a ring sealing main body 5 to be engaged with an inner marginal part of the through hole 1a and a plural number of narrow paper tablet type sheet pieces 6 projected in the inside diametrical direction in a state to be overlapped with each other from the sealing main body 5. A plural number of these sheet pieces 6 are deformed along an outer peripheral part of the piping 3 passed through by an inner peripheral surface part of the sealing main body 5 and seal the part between the piping 3 and the inner peripheral part of the sealing main body 5. Consequently, even when the number and the thickness of the pipings 3 passing through the through hole 1a variously differ, a plural number of the sheet pieces 6 are deformed along the outer peripheral part of the piping 3 and can seal the part between the inner peripheral part of the sealing main body 5 and the piping 3.</p> |
