Abstract
A shock absorbing racket structure comprising a head frame, a handle, and a pair of yoke bars connecting the head frame to the handle. Wherein, the yoke bars are hollow tubular members extending through the handle to a butt plate, forming a pair of cylindrical chambers within the handle. Within each cylindrical chamber is lodged a bullet-shaped resilient body, from which extends an axial rod, on whose rear termination is attached a support plate common to both axial rods and backed by the butt plate.
