PROBLEM TO BE SOLVED: To provide a highly attenuating rubber composition which enables compounding a large amount of carbon black capable of combining high attenuating performance and processability, and a quake-free structure excellent in attenuating performance. SOLUTION: The highly attenuating rubber composition 2 comprises 100 pts. wt. rubber component composed of a diene rubber, 40-95 pts. wt. carbon black having a cetyltrimethylammonium bromide (CTAB) adsorptive specific surface area of 100-170 m<SP>2</SP>/g, and 10-50 pts. wt. resin, and the resin has a≥10 wt.% content of a resin having a softening point of 100-180°C. The quake-free structure 1 uses the highly attenuating rubber composition. COPYRIGHT: (C)2006,JPO&NCIPI
