  In the ball game machine according to the present invention, the holding member made of an elastic wire having a bent latching portion is arranged and fixed on the mounting surface of the synthetic resin member. It can be reduced as much as possible. Thereby, simplification of molding dies, such as mounting parts, is achieved, and no extra effort is required for the production. On the other hand, since the holding member can be manufactured only by bending the wire, the manufacturing is easy and the product cost is low. Therefore, there is a beneficial effect that molding of mounted parts and the like can be simplified and the product cost can be reduced.

  In addition, since the engaging portion is engaged with the engaged portion and the holding member is bent against its elasticity to bend the bent latching portion on the mounting component, Unnecessary external force is rarely applied to the joint portion or the engaged portion. Therefore, the engagement portion and the engaged portion are hardly damaged, and there is an effect that these damage accidents can be suppressed as much as possible.

  In addition, the holding member is placed and fixed in the vicinity of the mounting part in contact with the mounting surface, and the mounting part is mounted simply by bending the holding member against its elasticity and hooking the bent latching part to the mounting part. Since this is possible, there is an effect that the mounting component is very easy to mount. In addition, since an operation unit that can easily operate the holding member with a finger is provided on the holding member, there is an effect that the holding member can be easily operated, and the attaching / detaching operation of the mounted component is simplified.

Since the holding member 30 made of is arranged and fixed, the engagement protrusion 16 and the engagement hole 21 for mounting the ball discharge device 12 can be reduced as much as possible. Thereby, simplification of the molding die of the ball dispensing device 12 and the mechanism plate 4 is achieved, so that extra labor is not required for the production thereof. In particular, in this case, the hooking projection 18 as in the present invention is not required on the lower surface of the ball dispensing device 12, and the labor for manufacturing the molding die can be further omitted. On the other hand, since the holding member 30 can be manufactured only by bending the wire, a mold is not required, the manufacturing is easy, and the product cost is low. Accordingly, the ball dispensing device 12 and the mounting surface 19 of the mechanism plate 4 can be easily formed, and the manufacturing costs thereof can be reduced.

  Further, the engagement protrusion 16 is engaged with the engagement hole 21, and the holding member 30 is bent against its elasticity, so that both the folding engagement portions 31, 31 are engaged with the ball dispensing device 12. Therefore, unnecessary external force is hardly applied to the engagement protrusion 16 or the engagement hole 21 when the ball dispensing device 12 is attached or detached. As a result, the engagement protrusion 16 and the engagement hole 21 are hardly damaged, and these damage accidents can be suppressed as much as possible.

  In any of the above explanations, the ball dispensing device is shown as the mounting part. However, for example, it is engaged by the engaging portion and the engaged portion such as a synthetic resin tank rail, a curve rail and the like so as to be detachable. Applicable if applicable. Moreover, although the engaging part was provided in the mounting component and the engaged part was provided on the mounting surface, they may be reversed.
