Abstract
A noise insulation structure of a synthetic resin made conduit includes a synthetic resin made chamber and a rubber made noise insulation member. Since the chamber is closely covered around with the noise insulation member through projections and grooves formed on the contact surface of the chamber with the noise insulation member. Further, cylindrical blind-end bores are provided on the inner surface of the noise insulation member so as to form air columns when the noise insulation member is installed on the chamber. The air columns serve as resonators to muffle noise.
