(57) [Summary] [PROBLEMS] To provide a tennis racket which does not have a strange appearance, has a large sweet area, and has high strength. SOLUTION: A face portion 2C of a tennis racket 1C.
Has a round outer periphery, and two substantially linear portions 7, 9 are provided on the inner periphery at two locations, a face top and a face bottom. The substantially straight portions 7 and 9 extend in a direction orthogonal to the long axis direction of the tennis racket. Gut lengths stretched between the substantially linear portions 7 and 9 symmetrical to each other are uniform, and the sweet area is wide. In addition, since the outer periphery is round, there is no corner where stress is extremely concentrated, and the strength of the tennis racket is high.

Generally designates a face portion 2, a shaft portion 3 and a grip portion 4.
The face portion 2 is provided with guts vertically and horizontally. Although the face portion 2 of the tennis racket 1 shown in FIG. 4 is substantially elliptical, the fifth portion shown in Japanese Utility Model Publication No.
There is also known a tennis racket 1A in which the face portion 2A is closer to a square than that in FIG.

ることが知見された。SUMMARY OF THE INVENTION The inventor of the present invention has conducted repeated studies to enlarge the suite area of a tennis racket, and has found that it is effective to make the gut length uniform. For that purpose, it has been found that it is effective to make the face portion more square than that shown in FIG.
【０００４】ところが、第５図よりもさらにフェース部
を方形に近づけると、コーナー部Ｃ付近に打球時の応力
が集中し、テニスラケットの強度が不足するようになる
ことが見出された。However, it has been found that when the face portion is made closer to a square shape than in FIG. 5, stress at the time of hitting is concentrated near the corner portion C, and the strength of the tennis racket becomes insufficient.

た。Therefore, the inventor of the present invention has made the outer periphery of the face portion round as shown in FIG. 6 and provided one or two pairs of parallel portions 5 on the inner periphery.
A trial tennis racket 1B provided with was prepared, and its characteristics were measured. As a result, it was recognized that the gut length was uniformed by providing the parallel portion 5, and the sweet area was widened.

Further, since the frame thicknesses t 1 , t 2 , and t 3 of the face portion 2B in the face surface direction change near the corner portion C, it was also recognized that the stress at the time of hitting was concentrated near the corner portion C.
