PROBLEM TO BE SOLVED: To provide an intake noise reduction device capable of suppressing reduction in flow rate of air while suppressing deformation of a rectification net part.SOLUTION: An elastic body-based intake noise reduction device 100 includes an annular gasket part 110, and a rectification net part 120 provided integrally with the inside of the gasket part 110, comprising a plurality of linear parts, and reducing intake noise by rectifying air flow; and is arranged on the downstream side of a throttle valve in an intake pipe to reduce intake noise. The plurality of linear parts constituting the rectification net part 120 includes a plurality of stem parts 121 extending in a radial direction, and a plurality of branch parts 122 respectively fixed only to one end side of each of the stem parts 121, and finer than the stem parts.SELECTED DRAWING: Figure 1 |
