Abstract
A soundproof wheel includes a soundproofing device which is mounted to an inner peripheral surface of a rim section of the wheel. The soundproofing device is provided with: a fixing ring which is fitted in and fixed to a groove formed in the inner peripheral surface of the rim section; an elastic body section which is adhered to an outer peripheral surface of the fixing ring, is disposed within the groove, and has a plurality of elastic body pieces; and an additional mass section which is adhered to an opposite side of the elastic body section with respect to the fixing ring, is disposed within the groove, and has a plurality of additional mass pieces. The soundproofing device includes a plurality of dynamic vibration absorbers, each having an elastic body piece and an additional mass piece. This soundproof wheel allows for reduction in wheel vibration noise and is highly durable.
