PROBLEM TO BE SOLVED: To prevent the fatigue of the hand and the lowering of gripping power for the launching operation of a game ball by dispensing with gripping of a grip part when launching the game ball. SOLUTION: In the game machine, an operation part 50 is provided with: an opening space part 50a into which a prescribed matter can be inserted; and a pressurization member 65 which can be changed from a non-pressurizing state where the prescribed matter H inserted to the inside of the opening space part can freely be pulled out from the opening space part 50a without being pressurized to a pressurizing state of pressurizing the prescribed matter inserted to the inside of the opening space part 50a to fix it in the opening space part 50a. The operation part 50 is provided with a pressurization member driving control means for drive-controlling change of the pressurization member 65 between the non-pressurizing state and the pressurizing state. In the pressurizing state of pressurizing the prescribed matter H inserted to the inside of the opening space part 50a by the pressurization member 65, the operation part can be turned with turning of the prescribed matter H via the pressurization member 65.
