PROBLEM TO BE SOLVED: To provide a winning ball unit capable of supplying a winning ball quickly, reducing friction load by making the outer wall contacting the winning ball during the period between when it is received one by one and supplied to minimize the contacted part of the winning ball with the outer wall. SOLUTION: The winning ball unit comprises the winning ball path to supply the winning ball by joining the two winning ball paths together into one path at the downstream on the surface, a pair of cams forming a pair of depressed parts to support the winning ball at a certain location of the junction of the two winning ball paths and a cam driving device connected with a gear so as to the depressed parts of the pair of cams rotate reversely out of alignment by approximately 90 degrees.
