PROBLEM TO BE SOLVED: To provide an intake noise reduction device capable of suppressing deformation of a rectification net part comprising an elastic body.SOLUTION: An elastic body-based intake noise reduction device 100 includes: an annular gasket part 110 sealing a gap between the end surface of one pipe and the end surface of the other pipe out of two pipes constituting an intake pipe; and a rectification net part 120 provided integrally with the inside of the gasket part 110, constituted with a linear part formed into a mesh shape, and reducing intake noise by rectifying flow of air, and is arranged on the downstream side of a throttle valve in the intake pipe and reduces intake noise. In the rectification net part 120, provided is a high-rigidity mesh part 122 whose mesh is locally constituted finely.SELECTED DRAWING: Figure 1 |
