Abstract (en)

A racket (10, 40, 50, 60, 70, 80) with improved strength and low air resistance includes a head frame (20, 41, 66, 72, 82), a connecting portion (30) extending from the head frame (20, 41, 66, 72, 82), and a handle fastened to a free end (31) of the connecting portion (30). The head frame (20, 41, 66, 72, 82) is provided with an inner circumference surface (22, 44, 56), an outer circumference surface (25) and two annular surfaces (26, 52, 62, 74, 84) connecting between the inner circumference surface (22, 44, 56) and the outer circumference surface (25). The annular surfaces (26, 52, 62, 74, 84) are provided with a plurality of concavities (27, 54, 64, 76, 86) adjacent to the inner circumference surface (22, 44, 56) such that an edge of the inner circumference surface (22, 44, 56) has a waved shape. By means of the aforesaid arrangement, the racket (10, 40, 50, 60, 70, 80) has improved strength and low air resistance and is easy to manipulate.
