(57) 57 The device comprises a holder (7, 43) for application to the shaft of a tennis
racket, particularly either (7) in a front region (1) or (43) in the handle region
(3) extending between the handgrip (2) and oval frame (1). The holder carries damping
cells (9, 44) formed preferably by cylindrical chambers with their axes perpendicular
to the plane of the racket and being part-filled with a heavy liquid or completely
filled with two liquids having different densities or with a granulate medium. Vibration
generated in the racket result in the heavy liquid or granulate medium being shaken
and dissipate energy, thus damping such vibration.
