The ball collecting drum includes: a plurality of discs; an annular multi-row groove including annular grooves formed between adjacent discs of the plurality of discs. Ball pockets formed, on an outer periphery of the plurality of discs in the annular groove formed between the adjacent plurality of discs have elasticity to allow entry and exit of a ball, and are continuously formed in each of the annular grooves. Each of the ball pockets has a size so that only one ball is allowed to be held therein. The ball pockets formed in the adjacent annular grooves are formed at positions deviated from each other in a circumferential direction of the annular grooves.
