| 摘要 | A racket (1) includes: a handle (30); a shaft (20); and an annular frame (10). The frame is connected to the handle through the shaft. The frame includes: a central region (12) in a shaft-axial direction along which the shaft extends; a root region (13) located in a shaft side area relative to the central region in the shaft-axial direction; and a tip region (11) located in a racket-tip side area relative to the central region in the shaft-axial direction. The central region is smaller in thickness (TH1) in a direction perpendicular to a plane defined by the frame than the root region (TH3) and the tip region (TH2). | ||||||
