发明名称 Tennis racket
摘要 In construction of a tennis racket having a frame top and a yoke, balance adjusters having specific gravities larger than that of a frame are arranged at the frame top and the yoke, respectively, with a specified mass ratio between the two balance adjusters. Repulsion characteristics are much improved and vibratory impact is mitigated even at off-spot shooting whilst assuring long and speedy fly of balls with reduced physical damages on players.
