    摘要: To provide a friction pulley which can transmit a high torque.
    A friction pulley (50) includes a rotatable rotary wheel (40) having a groove (4) on an outer periphery thereof, and a rubber ring (3) formed so as to be able to be accommodated in the groove (4). The friction pulley (50) is characterized by the following: the groove (4) has a pair of side surfaces (16, 26); the rubber ring (3) has a contact surface (33) which is brought into pressure contact with a rotary member so as to transmit power on an outer periphery thereof, and friction surfaces (31, 32) which are a pair of surfaces corresponding to the groove (4); at least in a power transmission state where the contact portion (33) is brought into pressure contact with the rotary member so as to transmit power, the friction surfaces (31, 32) of the rubber ring (3) are pushed to the side surfaces (16, 26) of the groove (4); and the friction pulley (50) includes separation preventing devices (51, 53) for preventing separation of the rubber ring (3) from the groove (4) in an outward 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.

    摘要: Provided is a sealing device that is capable of not only suppress the generation of unusual noise by guiding a gas flow but also suppressing the generation of unusual noise caused by resonance between the gas flow and a pipe, and that is superior in installation workability and ability to maintain posture of a gasket portion. An intake noise reduction portion (20) is characterized by including a flow-guiding net portion (21) for guiding a gas flowing in an intake pipe, an annular frame body portion (22) for supporting the flow-guiding net portion (21), a cylindrical portion (23) that extends from the frame body portion (22) in a direction in which the pipe extends, and is fitted into an inner circumferential surface of a second pipe (220) and a flange portion (24) that extends from an end portion of the cylindrical portion (23) toward an outer circumferential surface side, and is disposed in a space between an end surface of a first pipe (210) and an end surface of the second pipe (220). A gasket portion (10) is provided on both surfaces of the flange portion (24).
