Abstract
In construction of a racket frame, its head defining a face is made up of a plurality of elongated members coupled to each other in a manner to allow elastic deformation at shooting balls of the elongated members towards the center of the face so that impulsion caused by shooting balls should be shared by the head in order to mitigate impulsive load on strings forming the face.
