    • PURPOSE: To provide a ball game tool with which the aged, the handicapped, and children can enjoy oneselves by furnishing a lever in the form of a fishing rod at whose tip a ball is fixed, pivoting the lever on the top of an upright installed stay in such a way as rotatable both in the horizontal direction and the vertical direction, and installing a weight behind the piveting point. CONSTITUTION: A ball 2 is fixed to the tip of a lever 1 in the form of a fishing rod. The lever 1 is made of an elastic material such as glass fiber, carbon, etc., and the rear of the lever 1 is pivoted on the top of a stay 3 installed upright on the ground (or floor) in such a way as rotatable both in the horizontal direction and the vertical direction. In lieu of upright installed stay ay may be dangled from the ceiling at whose bottom the lever 1 is pivoted. A weight 7 is slidably installed near the tail of the lever 1 so that the apparent weight of the ball 2 is lessened. Also, the apparent weight of the ball 2 can be adjusted by replacing the weight 7 on the lever 1 with another one weighing differently.
