PURPOSE: To attenuate abruptly impact vibration in the use of sporting goods and prevent an uncomfortable feeling and the numbness of a grip by compressing and receiving a vibrator element having a weight covered by an elastic body in a case removably attached to an attached body.
CONSTITUTION: A case 5 is formed cylindrically with ABS or nylon for example and a cylindrical lead rod is cut to form a weight 1. On the other hand, a formed elastic body consisting of soft foamed polyurethan having 3-300kg/cm2 of a repulsive force is cut to a predetermined size to envelope the weight 1. The foamed elastic body including the weight 1 is enveloped by a solid elastic body 3 having 0.5-200kg/cm2 of stress in 50% of the elongation. The elastic body-covered vibrator element is received in the case 5 while the foamed elastic body 2 is compressed with 200-500% of compressibility, and fixed such that the weight 1 is not moved even if the case is swayed manually. And a lid 6 is secured fixedly to both ends of the foamed elastic body 2 with adhesives. This is secured fixedly to a grip end of a tennis racket or the like.
