发明名称 Racket
摘要 In a frame of a fiber reinforced plastic tennis racket made by molding process, thickness of the racket frame is reduced in an area starting from the throat to grip portion, and more preferably in the throat portion, to mitigate the bending stiffness of the frame at the portion thereby effectively hindering direct transmission of impact on the playing face to players' hands.
