<p>A shock-absorbing device is designed for use in ballgame goods having a tubular rod-shaped body and is composed of a tubular body and a weight. The tubular body is made of a soft elastic material. The weight is disposed in the tubular body such that weight is connected with the tubular body, and that an interstice is located between the outer surface of the weight and the inner wall of the tubular body so as to enable the weight to vibrate in the tubular body. The tubular body of the shock-absorbing device is disposed in the inner wall of the tubular rod-shaped body of the ballgame goods. The tubular body is capable of absorbing shock wave of the ballgame goods. The vibrational motion of the weight is capable of canceling shock wave of the ballgame goods.</p> |
