PROBLEM TO BE SOLVED: To provided a ball distribution device capable of distributing balls stably and in a short time to a ball bearing having many balls. SOLUTION: This ball distribution device arranges a plurality of balls 4 inserted between an inner ring 2 and an outer ring 3 of the ball bearing 1 in a given intervals. This device comprises a vertical rotary axis Y; a rotary comb 5 having comb teeth 5a in the same number of the balls 4 of the ball bearing 1 arranged around the rotary axis Y in intervals permitting the balls to be contained one by one; a mechanism (rotary driving mechanism 6 and lifting mechanism 7) for rotating the rotary comb 5 around the rotary axis Y and lifting them vertically; a plurality of plunger 8 for pressing elastically the ball bearing 1 from vertically above; and a radial force applying mechanism 12 for horizontally pressing an outer peripheral portion of the outer ring 3 of the ball bearing 1 toward the rotary axis Y of the rotary comb.
