Abstract:
In a racket frame, a yoke part is disposed between left and right portions of a bifurcated throat part continuous with a head part and with a shaft part. A ball-hitting face is formed with the yoke part and the head part. The head part and the yoke part have a plurality of string holes formed in penetration therethrough to insert longitudinal and transverse strings therethrough. Longitudinal string holes formed outside left and right sides of the yoke part connected with the left and right portions of the throat part are extended to the throat part to form extended longitudinal string holes open on an outer surface of the throat part.
