Abstract
The intake noise reduction device is capable of suppressing hindrance to the airflow caused by deformation of a flow-regulating net portion and suppressing a reduction in the airflow amount. A linear portion having a mesh shape constituting a flow-regulating net portion 120 includes a circumferential linear portion 122 that extends circumferentially and, an radial width t1 in the upstream side, with respect to the airflow direction, of the circumferential linear portion 122 is larger than a radial width t2 in the downstream side thereof, and a radially outer surface 122A is constituted by a tapered surface that tapers toward the downstream side.
