PROBLEM TO BE SOLVED: To provide a racket frame allowing a comfortable sense of stroking a ball to be obtained at the time of stroke and making fatigue hard to cause to the wrist, elbow, and the like, of a player by reducing the shock and vibration propagated to the hand of the player from a grip part at the time of stroke to a satisfactory level. SOLUTION: A grip part 5 is formed in a three-layer structure comprising the body layer of the grip 7 made of a fiber reinforced resin, a viscoelastic material layer 8 covering the body layer of the grip 7 and a thin hard shell 9 that is arranged in the circumference of the viscoelastic material layer 8 and is independent from the body layer of the grip 7 by the viscoelastic material layer 8. |
