Abstract
The badminton racket () includes a frame (), a handle () and a shaft () connecting the frame to the handle. It defines a first direction (D) parallel to a longitudinal axis (X) of the shaft, a second direction (D) perpendicular to the first direction and parallel to a plane (P) in which strings () extend mounted in the frame (), and a third direction (D) perpendicular to the first and second directions (D, D) and the plane (P) of the strings. The bending rigidity of the shaft () in the third direction (D) is greater than its bending rigidity in the second direction (D).
