Further, in the first embodiment, the positioning hole portion 38
The positioning protrusion 40 is formed at a position where it partially overlaps the left and right vertical plates 32 in the left-right direction, but does not necessarily have to be formed at a position that overlaps the left and right vertical plates 32. In that case, when the front plate cover 35 is attached to the front plate 34, the rear end side of the positioning protrusion 40 may protrude rearward from the rear end of the front plate 34. In order to prevent the front plate 34 from bending during press fitting, the positioning holes 38 and the positioning protrusions 40 and the left and right vertical plates 32 are arranged in the left-right direction.
It is desirable that and are as close as possible.

The shapes of the positioning protrusion 40 and the engaging portion 41 are not limited to those in each embodiment. For example, in the positioning protrusion 40, the core 55 may be formed in a tapered shape without providing the positioning rib 56. That is, if the positioning protrusion 40 and the engaging portion 41 can position and engage the front plate cover 35 with the front plate 34 via the positioning hole 38 and the engaging hole 39 on the front plate 34 side, The shape may be changed appropriately. The engaging protrusion 58 of the engaging portion 41 is not only directed downward,
It may be configured to project upward, laterally, or the like so as to engage with the back surface of the front plate 34 on the upper side, the lateral side, or the like of the engagement hole portion 39.
The elastically deformable direction of the strip plate portion 57 may be appropriately changed according to the protruding direction. In that case, the protection part 59 may be provided so as to cover the engagement part 41 from the side opposite to the protruding direction of the engagement projection part 58. The shape of the protection part 59 may be changed as appropriate, or may not be necessarily provided.

In the embodiment, the standing wall portion 53 is provided on the rear end side of the front plate upper cover portion 46 of the front plate cover 35, but the standing wall portion 53 is provided on the rear side of the front plate upper cover portion 46. It suffices that it is provided so as to correspond to the lower end of the front plate upper cover portion 46, and it does not have to be the rear end side. In the embodiment, the outer frame 2 and the front frame 5 are made of wood such as laminated plywood, but may be made of synthetic resin material or the like. Although the vertical plate 32, the horizontal plate 33, and the front plate 34 of the outer frame 2 are fixed by the tapping screws 42, they may be fixed by other screws, nails, bolts, nuts, or the like.

Besides, the present invention is not limited to a pachinko machine, but can be similarly implemented in various ball game machines such as an arrangement ball and a sparrow ball game machine.
