PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing a space necessary for arranging a rotor having a portion to be detected.SOLUTION: A right gear member 790R comprises: an annular rib 793 having an axially annular shape erected on an axial end face; and an intermittent portion 793a formed by notching a portion of the annular rib 793, and this annular rib 793 is a detected portion to be detected by a rotational position detection sensor. As compared with the case, in which the detected portion extends radially outward from the outer circumference of the right gear member 790R, therefore, a moving space to be retained can be suppressed to reduce accordingly the space required for the arrangement. Moreover, the rotational position can be detected, while reducing the space necessary for the arrangement, and the rigidity of the right gear member 790R can be enhanced by the annular rib 793. |
