SOLUTION: The role object A for a pinball game machine is provided with the case body 3 which has an internal cavity, which is surrounded in a closed state, and in which the operation members 30 and 31 are incorporated for performing prescribed operation and a driving means 32 for operating the operation members 30 and 31. The operation members 30 and 31 are arranged in the vicinity of the inner surface of a top wall 14a or that of a bottom wall 14b. At sites opposing the operation members 30 and 31 of the top wall 14a or the bottom wall 14b, release holes 36a and 36b of a proper size where the operation members 30 and 31 can partially be interposed and their operation are not disturbed.
