The apparatus comprises an actuating section (1), an axle (2), a drive section (3), a ball member (4) and a display unit (5). Upon hitting the ball (4) which is integrally attached to a rod (10) linking via cylinder (6) with the actuating section (1), the reduced track of the ball flying is displayed on the screen (5) indicating the position of the ball in flying with the direction, speed, flying angle and distance of the flying as in the true flying track. The ball returns automatically to the original position for the next practice, and the practicing person can see the result of the hitting for possible correction.
