PROBLEM TO BE SOLVED: To provide a pinball game machine which enables the building of a ball rolling part in a stable structure. SOLUTION: A stage constituent member 200 is built up of an upper stage 25U, a front constituent plate 99 and game ball downflow parts 94 and 94 in an integral structure. As compared with the assembly of separate parts, this structure can cut back the number of the parts while achieving a stable structure. In the stage constituent member 200, the upper stage 25U and the front component plate 99 are linked with game ball downflow parts 94 and 94 protruding ahead of the upper state 25U, a novel configuration unavailable in a conventional pinball game machine which makes the form of a decoration frame 23 more attractive. Moreover, the stage constituent member 200 is fixed on the decoration frame 23 and a game board 11, thereby further stabilizing the mounting state of the stage constituent member 200 on the decoration frame 23.
