PROBLEM TO BE SOLVED: To provide an air introduction duct having the good assembling workability. SOLUTION: The air introduction duct 1 comprises a duct main body 2, a resonator connector 3 projected from the duct main body 2, and a resonator 4 connected to the resonator connector 3. A connection end surface 6 at the duct main body side and a connection end surface 5 at the resonator side are formed so that the resonator connector 3 and the resonator 4 are connected in the direction perpendicular to the resonator 4 longitudinal direction. The resonator connector 3 and the resonator 4 are connected with each other via a snap fit mechanism 10 straddling over both the end surfaces. A projection 13 is formed over the whole periphery of either one end of the connection end surface 6 at the duct main body or the connection end surface 5 at the resonator side. A recess 14 is formed to store the projection 13 over the whole periphery of the other end surface. COPYRIGHT: (C)2007,JPO&INPIT
