A resonator divides and forms a sound attenuation space and maintains airtightness without external force. The resonator includes a tubular cover body and having a hollow portion with different diameters, a tubular insert inserted into the cover body and having second hollow portion that turbocharger air is introduced into the second hollow portion, the air being guided into the first hollow portion on an outer surface of the insert body; and one or more space partition members coupled to the outer surface of the insert body to form airtight noise attenuation spaces. The partition members are ring shaped, and each space partition member is formed of a resilient material, and each space partition member has a contact portion formed by an inclined surface to be in contact with the inner surface of the cover body in a direction in which the insert body is inserted into the cover body.
