摘要： Provided is an intake noise reduction device that can mitigate deformation of a flow-regulating net portion made of an elastic body. The intake noise reduction device 100 made of an elastic body that is disposed downstream of a throttle valve in an intake pipe and reduces an intake noise includes an annular gasket portion 110 and a flow-regulating net portion 120 provided inside the gasket portion 110 integrally with the gasket portion 110, constituted by a linear portion having a mesh shape. The linear portion having the mesh shape constituting the flow-regulating net portion 120 includes first linear parts 121 that extend radially and second linear parts 122 that extend circumferentially. One of any given two parts of the first linear part 121 on a radially outer side has a width larger than or equal to that of the other part on a radially inner side, and a radially outermost part of the first linear part has a larger width than a radially innermost part.

摘要： A sealing property is improved.
A sealing device (1) is formed of an endless elastic body around an axis line (x). The sealing device (1) is mounted in an endless space (S) formed by a plurality of members (100, 101) facing each other so as to perform sealing between one side (c) and the other side (d) in the radial direction of the space (S). The sealing device (1) includes a main body portion (11) facing the plurality of members (100, 101) in the axis line (x) direction, projecting portions (13) on one side projecting from the main body portion (11) toward the one side (c) in the radial direction to face the plurality of members (100, 101), and projecting portions (14) on the other side projecting from the main body portion (11) toward the other side (d) in the radial direction to face the plurality of members (100, 101). A projecting amount of each projecting portion (14) on the other side toward the other side (d) in the radial direction is greater than a projecting amount of each projecting portion (13) on one side toward the one side (c) in the radial direction.

摘要： 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.
