The bearing structure (9-1 1) comprises a bottom wall or chest-bottom (7), and a top member or upper block (8), a central longitudinal batten or backboard (9), and two side battens or planks (10), which extend between the chest-bottom (7) and the upper block (8), remote from and close to the sound board (5), respectively; and a plurality of longitudinally staggered, transverse stiffening members or bridges (1 1) each of which is connected centrally to the backboard (9) and has its ends (1 lb) connected to the side planks (10). The bridges (1 1) are at least partially glued to the internal surface of said shell (12).
