In the region of the throat where the frame portion merges with the shafts there is provided an extruded metal throat-piece of which one wall completes in combination with said frame a striking area. The throat-piece has side walls formed complementary to the shafts. Holes pass through the throat-piece walls and align with holes provided in the frame and shafts and serve to receive the racket strings which draw the shafts towards the throat-piece and hold the latter under compression at the throat region. | |
