Abstract

PURPOSE: To develop and maintain an effect of a sound absorbing material for a long time, thereby reducing a rolling noise of a sound absorbing wheel by a device characterized in that not only a cavity between side plates of a wheel center is filled with the sound absorbing material, but also an attachment plate is attached so as to close a hole communicating to the cavity.
