Abstract: There is provided an automobile component capable of improving sound absorption performance by damping due to vibration of a thin film as well as reducing weight of the automobile component. An automobile component of the present invention includes a core layer 10 in which tubular cells 20 are arranged in a plurality of rows, and a nonwoven fabric layer 30 on one or both surfaces of the core layer. The cells have closed surfaces 21 and open ends 22 in every other row as cell ends on one surface of the core layer. As cell ends on the other surface of the core layer, the cells have open ends 22 in the rows where the cells have the closed surfaces as cell ends on the one surface, and have closed surfaces 21 in the rows where the cells have the open ends as cell ends on the one surface. The open ends 22 allow the internal space of the cells 20 to be in communication with the outside. A thin resin film layer 40 having a plurality of apertures is provided between the core layer and the nonwoven fabric layer. A ratio S is set so that 0

Abstract: In a first step, a molding die is immersed in a raw liquid including cellulosic fibers. Then, the liquid of a raw liquid is sucked through a net material by a liquid suction part, so as to cause the cellulosic fibers to be laminated on the net material. In the second step, the cellulosic fibers laminated on the net material are dried, so as to form a protrusion. In the third step, the dried protrusion and the communication part are removed from the molding die. A passage part of the communication part is formed at a position where a projection portion had been arranged, the passage part being configured to communicate an inside of the protrusion with an outside of the protrusion.

Abstract: A sound absorbing structure includes a vehicle structure having a surface and at least one acoustic scatterer coupled to the surface. The at least one acoustic scatterer has a resonant frequency. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end, the channel open end being in fluid communication with the opening. The sound absorbing structure may be configured to absorb sound waves at a certain frequency generated by a noise source. The certain frequency may be substantially similar to the resonant frequency of the at least one acoustic scatterer.

Abstract: A dust cover for a steering apparatus of a vehicle includes a first cover coupled to an intermediate shaft in a state in which a bearing member is interposed and fixed to a vehicle body panel. The dust cover also includes a second cover coupled to the intermediate shaft in the state in which the bearing member is interposed and fixed to the vehicle body panel together with the first cover in a state of being bonded to the first cover. A tight contact rib in a long continuous shape along a periphery of the intermediate shaft is formed to protrude from the first cover such that the tight contact rib maintains airtightness between the first cover and the vehicle body panel in a state of being always in a tightly adhered state with the vehicle body panel.
