The present trainning apparatus is adapted to use as a training machine for ball games such as pingpong ,tennis, baseball, softball, volleyball, football etc. For example, five air pipes 31 (P1, P2, P3, P4, P5) are employed in the driving means which is actuated by compressed air. On-off of the compressed air is controlled by each air solenoid valve 34 located at the base of the pipe 31. Spinning a ball can be effected by flowing the compressed air through any one of the pipes 31. Suitable pressure of te compressed air is from 1 to 5kg/cm, and the velocity of a ball can be varied by changing the pressure
