Abstract: A ball feeding device which can feed balls one by one without allowing many impacts on the balls and which can prevent the balls from being magnetized. Balls are accommodated in a housing formed with a conical hole in the bottom thereof. A rotary rod having a conical end is mounted in the housing, the conical end being located near and opposite to the conical hole. Balls are guided one by one into the area between the conical end and the conical hole and discharged one by one through the conical hole. A pair of inclined cylinders are provided under the housing. The balls discharged through the conical hole drop onto the higher end of the gap defined between the cylinders and roll along the gap. The gap expands gradually from the higher end toward the lower end. Thus, the balls drop through the gap into a pan provided under the cylinders while being fed along the gap.
