PROBLEM TO BE SOLVED: To provide a pachinko game machine with a winning device which permits a quick removal of game ball caught during the change of an opening and closing member to a closed position. SOLUTION: A vibration generation means is formed by the opening and closing member 21A always urged in a closing direction by an urging member 29 to a closing direction, suppressed protrusion portions 32a and 32b are arranged in either of linking members 34a and 34b engaged with the opening and closing member 21A only when an opening driving means drives to open and to open and force out the opening and closing member 21A in an opening direction and pressurizing protrusions 35a and 35b capable of butting against the suppressed protrusion portions 32a and 32b in a vertical direction are arranged in the other. The suppressed protrusion portions 32a and 32b and the pressurizing protrusions 35a and 35b relatively slidingly rub against each other in a butting condition with the return action of the linking members 34a and 34b previously pulled back and the pressurizing protrusions 35a and 35b and causes vibration in the opening and closing member 21A when the occurrence of catching of a game ball between the upper opening edge of a winning opening 22 and the inside face of the opening and closing member 21A stops the opening and closing member 21A on its way back to the closing position.
