PROBLEM TO BE SOLVED: To provide a winning hole unit capable of replacing a part exposed to the surface side of a game board. SOLUTION: This winning hole unit 5 constituting a regular electric generator integrally with a winning hole is so formed that a passing hole member 55a (55b) is adapted to be replaceable relative to an attachment member 51 so as to change over between a winning hole unit 5a of a type also served as a sensor 57 for detecting the winning of an operation-start winning hole and a winning hole unit 5b of a type non-served as the both. Alternatively, a back side driving device 50B is detachably formed relative to an opening/closing device 52 exposed to the surface side so as to replace the opening/closing device 52.
