发明名称 Wooden racket frame
摘要 At least one end surface of a racket frame is occupied by a wooden shell layer obtained by transversely slicing a given elongated wooden material. Transmission of shock on the playing face onto user's hand holding the grip section is well hindered, and development of cracks and generation of wooden burrs are well prevented at drilling of through holes for strings.
