PROBLEM TO BE SOLVED: To provide a ball cover capable of adjusting a position of a ball to be stored and retaining a position after adjustment, facilitating adjustment of the air volume of the ball so as to finely adjust strength whenever hitting on the body, and putting into a mat-like state by connecting a plurality of covers in a plane direction.SOLUTION: A ball cover 1 is for a ball 2 comprising an elastic member which has an air injection/discharge port 2a, and can inject air from the air injection/discharge port 2a into the inside and discharge so as to adjust an air volume inside. The ball cover 1 comprises a bag body part 3 for storing a plurality of balls in one row, a slit part 4 provided in the central part longitudinal direction of the bag body part 3, and ball position adjusting/retaining means 7 for adjusting and retaining the position of the ball 2 stored in the bag body 3. In the slit part 4, the ball 2 is formed so as to freely come and go.SELECTED DRAWING: Figure 1 |
