PROBLEM TO BE SOLVED: To adjust a pushing pressure to a prize by a gripping device. SOLUTION: A crane game machine 10 is provided with a catcher part 14 for gripping a prize. The catcher part 14 is vertically moved by a catcher vertical movement mechanism in a case where prizes are piled. A control part 30 presets a threshold for detecting a stress (pushing pressure) level generated by that the catcher part 14 is downward moved and press-contacts with a prize or the like. When detecting that the stress level to be detected by the stress sensor 37 reaches the preset threshold, the control part 30 stops the downward movement of the catcher part 14.
