ABSTRACT:
A badminton racket comprises a head, a shaft, and a hand grip. The hand grip is provided axially with a receiving hole of an appropriate depth for fastening the shaft with the hand grip. The receiving hole is provided at the bottom thereof with a conical portion becoming gradually smaller in dimension toward the upper end thereof from the lower end thereof. The hand grip is further provided axially with an elongate through hole extending from the upper end of the conical portion through the lower end wall of the hand grip. The adhesive coated on the inner wall of the receiving hole of the hand grip can not be therefore forced out by the shaft being inserted into the receiving hole of the hand grip during the process of fastening the shaft and the hand grip together.
