    • A structure of racket comprises generally an oval shaped head, a throat and handle, which is shaped by a tubular metal having an olive shaped cross section having a rectangular groove centrally extended along the length of the inward periphery and an arcuate groove centrally extended along the length of the outward periphery, both terminated at a position where the throat is latterly formed. The grooves are connected on their lateral sides by a pair of symmetrically arcuate ribe inside the tubular metal. A plurality of string holes are punched through the grooves in predetermined number and space prior to that the metal is bent into oval shaped. The handle is formed by juxlaposing two ends of the tubular metal and bound with vibration absorbing material. A separately made transverse portion screw secures to the inward periphery of the frame above the throat for stringing arrangement. This disclosure has been characterized in a simplized durable structure for saving the time and cost to manufacture.
