Tennis training device

Tennis training device, comprising

• a support bar (5) supporting a ball (1) and swivelable between a first stop (8) and a second stop (9) at a base,
• wherein the ball (1) is mounted at the free end of the support bar,
• characterised in that
• the ball (1) is mounted at a connecting member (20) which is releasably fixed at the free end of the support bar by a fixing means (20.2), wherein
• the ball (1) is
• mounted at the connecting member (20) in such a way as to be movable in different directions by
• means of an elastic extension (1a) which protrudes in radial direction from the ball,
• wherein
• a plate (20.3) is mounted at the connecting member (20) for supporting the ball (1) and wherein the plate (20.3) is curved concave on the side of the ball.
