To variously change a return ball by constituting a surface of a rebounding plate as an assembly of surfaces different in resiliency.

A rebounding plate is constituted so as to be supported by a backboard 1 by combining a surface 2 of resiliency A, a surface 3 of resiliency B and a surface 4 of resiliency C. The number of the respective surfaces 2 to 4 is properly freely combined. When hitting a ball toward these surfaces, the ball strikes on either of the surfaces 2 to 4 different in resiliency. A speed and a flying locus of a rebounding ball change by a difference in the resiliency A to C. The relationship between the locus of a hitting ball and the repulsive surfaces 2 to 4 can be properly selected. Thus, the number of repulsive surfaces, a combination and arrangement are optionally set so that a return ball can be variously changed.
