Abstract
PURPOSE: To improve the preciseness of shot without being influenced by the flying passage of a ball by providing a design so that the frequency of a dominant vibration mode excited in a racket in play is made to coincide with the ball/racket contact period. CONSTITUTION: The height of a racket frame is continuously increased from a dimension A in the top of the head part of the frame to a dimension B in the throat part of the frame, the maximum height B is produced in the area where throat members 21, 22 are combined to a head part 20. The maximum dimension B is substantially conformed to the center of a frame piece 24 in which the frame piece crosses the vertical central line CL. When set to such form and dimension, the racket has rigidity larger than a general racket, and an inertial moment to an intermediate surface MP is provided so as to have a desired frequency from 170Hz to 250Hz to the first mode of bending under free-free suppression.
