Abstract
A sound-absorbing material and a cable reel including the same are produced inexpensively and are able to attenuate sliding noise and vibration noise. A sound-absorbing material,is made of a polyethylene film,and is formed into a thin waved sheet having continuous wave crests and wave troughs. A synthetic paper,having a lubricative surface is attached to the wave crests on a front side of the polyethylene film,through an adhesive. As an air layer,is defined in a space surrounded by the wave crests and wave troughs, any sounds which are transmitted to the polyethylene film,collide on the wave crests and wave troughs thereby being effectively attenuated and absorbed. The sound-absorbing material,is struck on a bearing surface,of a stationary member,by way of an adhesive. A lateral lower edge of a flat cable,slides on the lubricative surface of the synthetic paper,, thereby suppressing generation of sliding noise. Vibration noise during an idling mode collides on the wave crests and wave troughs thereby being effectively attenuated and adsorbed.
