| abstract | (57) [Summary] [Purpose] To improve the strength of the top part of a tennis racket frame, which is apt to be damaged by a load, without increasing the amount of reinforcing fibers and increasing the weight. [Structure] The cross-sectional shape of the top portion 13 of the frame 12 is The thickness (W1) in the in-plane direction is 12 mm to 17 mm, and the relationship between the thickness (W1) in the in-plane direction and the thickness (W2) in the out-of-plane direction, W 2 / W1 is set in the range of 100% to 170%. In the range of 30 ° from the side to the shaft, The thickness (W1) in the out-of-plane direction is set in the range of 22 mm to 32 mm, and the relationship between the circumferential length (L1) of the cross section of the portion and the circumferential length (L1) of the top portion is L2 / L1 is set to be substantially the same in the range of 90% to 110%. |
