ABSTRACT:
A tennis racket or the like having a slip clutch in the handle of the racket. When a tennis ball strikes on or near the frame to the side of the tennis racket head, there is a tendency for the head of the racket to twist around a longitudinal axis extending through the handle of the racket. The slip clutch permits the head of the racket to rotate relative the handle of the racket to lessen the transmission of shock forces from the head of the racket to the arm of the user of the tennis racket.
