PROBLEM TO BE SOLVED: To provide an intake noise reduction device capable of suppressing obstruction of air flow due to deformation of a rectification net part, and thereby suppressing flow rate reduction of air.SOLUTION: An elastic body-based intake noise reduction device 100 is arranged on the downstream side of a throttle valve in an intake pipe, and reduces intake noise; and includes an annular gasket 110 and a rectification net part 120. On the surfaces of mesh-like linear parts 121, 122 constituting the rectification net part 120, a plurality of recess parts 123 reducing air resistance is provided.SELECTED DRAWING: Figure 1 |
