    • The present invention provides an air intake noise reducing device, an internal combustion engine fitted with the air intake noise reducing device and a structure for fitting the air intake noise reducing device to the internal combustion engine. The air intake noise reducing device comprises a gasket (2) comprising a ring member (2a) held by connecting surfaces of an air intake passage (100) and protrusion holding portions (2b) extending from the ring member (2a) toward a center of the air intake passage (100); and a net member (3) comprising a net (3a) for rectifying intake air and connecting protrusions (3b) extending outward from the net (3). The connecting protrusions (3b) are held in the protruding holding portions (2b) such that the ring member (3) is firmly secured to the gasket (3). The air intake noise reducing device constituted by in the above-mentioned manner can reduce assembly man-hours without deteriorating a sealing property of the air passage.
    • 本发明提供了一种进气噪声降低装置,配有进气噪声降低装置的内燃机和将进气噪声降低装置装配到内燃机的结构。 进气噪声降低装置包括垫圈(2),其包括由进气通道(100)的连接表面和由环形构件(2a)延伸的突起保持部分(2b)保持的环形构件(2a) 进气通道(100); 以及网构件(3),其包括用于对进气进行整流的网(3a)和从网(3)向外延伸的连接突起(3b)。 连接突起(3b)保持在突出保持部分(2b)中,使得环形构件(3)牢固地固定到垫圈(3)上。 以上述方式构成的进气噪声降低装置可以减少组装工时,而不会降低空气通道的密封性。
