Abstract

Official abstract text for this publication.

A sealing device that is capable of suppressing the generation of unusual noise by guiding a gas flow and suppressing the generation of unusual noise caused by resonance between the gas flow and a pipe. An intake noise reduction portion ( 20 ) includes a flow-guiding net portion ( 21 ) for guiding a gas flowing in an intake pipe, an annular frame body portion ( 22 ) for supporting the flow-guiding net portion ( 21 ), a cylindrical portion ( 23 ) that extends from the frame body portion ( 22 ) in a direction in which the pipe extends, and is fitted into an inner circumferential surface of a second pipe ( 220 ) and a flange portion ( 24 ) that extends from an end portion of the cylindrical portion ( 23 ) toward an outer circumferential surface side, and is disposed in a space between an end surface of a first pipe ( 210 ) and an end surface of the second pipe ( 220 ). A gasket portion ( 10 ) is provided on both surfaces of the flange portion ( 24 ).

First claim
