<P>PROBLEM TO BE SOLVED: To provide an inner fender capable of maintaining the sound absorbing action, without receiving influence such as mud and a pebble sprung up by a tire, by absorbing an echo sound of various noises generated in an engine room and road noise in the engine room. <P>SOLUTION: A plurality of air chambers 10 are formed by defining a hollow part formed in the inner fender 2 in the longitudinal direction of the inner fender 2. A duct 15 having a desired length dimension respectively communicates with a bottom part 14 of the respective air chambers 10, and a Helmholtz resonator is constituted of the air chamber 10 and the duct 15. An opening 15a of the duct 15 opens on an upper surface 2a on the opposite side of a tire opposed surface 2b in the inner fender 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
