  In the case of the pachinko gaming machine described above, a cylindrical boss portion directed in the front-rear direction is formed on each of the case support portions of the support frame, and through the screw insertion holes of the case on the inner peripheral surfaces of the both boss portions. The case is fixed in the case housing portion of the support frame based on screwing the screws. This support frame is formed from a synthetic resin material, and the positional relationship between the two boss portions tends to deviate from the design value due to the warp of the support frame. If the positional relationship between these bosses deviates from the design value, the bosses of the support frame are aligned with the screw insertion holes of the case based on the elastic flexure of the support frame. A screw is screwed to each of these in the elastically deformed state of the support frame. For this reason, since the elastic restoring force of the support frame acts on the case through screws from each of the boss portions of the support frame, the elastic restoring force of the support frame is transmitted from the case to the drive mechanism. This drive mechanism is configured by connecting a plurality of machine elements, and when the elastic restoring force of the support frame is applied to the drive mechanism, each of the plurality of machine elements is different from the operation direction of the machine elements. Since there is a possibility that an unreasonable stress in a different direction may act, smooth movement of the movable member may be hindered.
