PURPOSE:To decrease the burden applied on the wrists and elbows at the time of hitting a ball by inserting grommet into at least a part of gut insertion holes formed on a racket frame and projecting plural pieces of the grommets by a specified amt. or above to the face side. CONSTITUTION:This racket 1 is provided with plural pieces of the gut insertion holes on the racket frame 2 at prescribed intervals. The face bottom part of the racket frame is successively provided with two pieces of shank parts 3, 3 so as to form a triangle shape and the front end of the shank part is successively provided with a grip part 4. The grommets are inserted into the respective insertion holes and the guts are extended longitudinally and transversly through the grommets. The grommets 5 made of transparent material which are connected by bands 6 and have a part projecting to the face side are used for total 6 pieces of the gut insertion holes in the face bottom part enclosed by the shank parts 3, 3 in such a case. As a result, the vibration of strings is suppressed and attenuated. |
