One set of ball-giving device of hitting game, which is to improve the ball-giving mode of hitting game; top-side bushing is vertically inserted into base, supporting pipe with ball-supporting seat fixed at one end is imbedded and locked into top-side bushing, one induction eye is assembled inside ball-supporting seat, forced convection connecting with base is communicated with bushing and tube of supporting pipe via loop; basing on this structure combination, when induction electric eye induces position of ball, it then transmits the induced results to forced convection so as to start or turn off it, wind from forced convection device can blow ball into floating, so that player can hit ball easily.
