<p>PROBLEM TO BE SOLVED: To provide an air intake sound reduction device which can suppress the lowering of an air intake amount while suppressing the deterioration of a rectification function by suppressing deformation of a rectification net part, even if the rectification net part is constituted of an elastic body.SOLUTION: An air intake sound reduction device 100 which is arranged at the downstream side of a throttle valve in an air intake pipe, and formed of an elastic body, comprises: an annular gasket part 120 which seals a clearance between an end face of one pipe out of two pipes constituting the air intake pipe and an end face of the another pipe; and a rectification net part 110 which is integrally arranged at the inside of the gasket part 120, constituted of linear parts 111, 112 which are arranged in a net shape, and reduces an air intake sound by rectifying a flow of air. In the linear parts 111, 112, when widths are denoted by W, and depths are denoted by T, T/W is set to be not smaller than two and not larger than five.</p> |
