A shockproof device in the throat of a tennis racket includes a racket having a frame, a stringing surface in the frame, a throat of truncated triangular configuration under the frame and including a pair of tubular branches spacedly extending downward from the lower peripheries of the frame and a Y-shaped handle including a pair of solid branches spacedly extending upward and each having an elastic sleeve wrapped on inserted into the tubular branches in a predetermined depth and secured by adhesives, and a conical gap centrally formed in the bottom of the frame and filled up by an conical elastic projection of a sheath which wraps the frame. Thereby, the shock waves from the frame are partially hindered and absorbed by the conical elastic projection and partially absorbed by the elastic sleeves in the throat without transmitting to the handle.
