The distributing device 1 includes a ball inflow / outflow area 2 as a ball passage opening of the frame portion and a ball inflow / outflow prevention region 3 as a frame portion on the side wall in the circumferential direction having an approximately circular inner peripheral surface. The formed first rotator 4 and a second rotator 6 as a rotator having a plurality of ball receivers 5 opening toward the outer peripheral surface,
The rotating bodies 4 and 6 are rotatably mounted on the same axis so as to rotate by driving of a driving source.

More specifically, the first rotating body 4 is provided with, for example, four standing pieces 8 at equal intervals on the peripheral edge of a disk-shaped rotating substrate 7 and prevents the portion where the standing pieces 8 exist from blocking the inflow and outflow of balls. Area 3
The space between the standing pieces 8 is the ball inflow / outflow area 2, and the shaft hole 9 is opened in the rotating substrate 7. In addition,
In the illustrated embodiment, a cylindrical cylindrical shaft portion 10 is protruded from the rear side of the rotary substrate 7, and the cylindrical shaft portion 10 is provided with a shaft hole 9.

[0009] The second rotating body 6 is a standing piece 8 of the first rotating body 4.
And a rotating shaft 12 rotatably inserted through the shaft hole 9 of the first rotating body 4 at the center on the back side of the rotating disk 11. The rotating disk 11 is provided with a plurality of ball receiving portions 5 that open toward the outer peripheral surface. For example, in the embodiment shown in FIG. 3, five ball receiving portions 5 are provided in a cutout shape, in other words, five arm portions 13 extend substantially radially from the central portion.

In addition, as an inclined portion of the ball bite prevention device,
The rear end edge 13 ′ of the arm portion 13 is cut off at an angle on the front surface 13 b side so as to be inclined, and the taper portion 13 a is inclined toward the front surface 13 b.
Is provided. Note that the tapered portion 13a may be provided at a corner of the back surface 13c of the arm portion 13.
