に多様な変化が与えられていた。2. Description of the Related Art Conventionally, a component called a windmill is mounted on a game board of a ball game machine represented by a pachinko machine. This windmill is composed of a nail driven substantially perpendicularly to the surface of a game board and an impeller rotatable around the nail. When a game ball falling from above collides with the impeller, the impeller rotates. With the rotation of the game ball, the game ball is distributed to the left or right, or the force of the rotation of the impeller causes the game ball to fly farther, thereby giving various changes in the falling direction of the game ball.

ため、遊技球との衝突に伴って羽根車が摩耗したり破損
したりしやすく、こうした損傷が過度に大きくなれば、
風車としての役割を果たさなくなる恐れもあった。By the way, in the above-described windmill, since a large number of falling game balls collide one after another, the impeller is worn or damaged due to the collision with the game balls. And if the damage is too great,
There was also a risk that it would no longer serve as a windmill.

を得なかった。[0004] However, in the above-mentioned conventional windmill, the nail serving as the shaft of the impeller is driven into the game board, and the nail cannot be easily pulled out. Therefore, only the windmill cannot be easily replaced. There was a problem. Of course, if you do not choose a means, it is not impossible to forcibly pull out the pin of the windmill, but even if you forcibly pull out the nail, the hole will remain on the game board, so the original Attempting to attach the windmill to the location would result in the nail being driven into the hole on the game board, which could cause rattling of the windmill and reduce the strength of the windmill. there were. Also, if the nails are driven in such a way that they do not overlap the holes on the game board, the strength of the windmill may be secured, but the flow of the game balls will change as the windmill mounting position changes, and Since the winning probability may become too large or too small, a change in the wind turbine mounting position may result in an illegal remodeling of the gaming machine. Furthermore, if the nail is driven so that it does not overlap the original hole, the original hole remains on the game board, so it can be seen from the player side, and it looks extremely bad, regardless of whether it is an illegal modification or not. There were also problems. Therefore, it is extremely difficult to replace only the windmill while avoiding these problems, and if the impeller of the windmill is damaged, the entire game board or the entire game machine must be replaced with a new one. I didn't get it.

4, the service life of the rotating member 12 can be extended as compared with the case where the rotating member 12 is formed of a material having the same wear resistance as that of the rotating member 12. Further, compared to the case where both the impeller 14 and the rotating member 12 are formed of a material having high wear resistance, the impeller 14 can be formed with a less expensive material, and the manufacturing cost of the impeller 14 and the production cost of the windmill can be reduced. Can be suppressed. Further, as described above, the fixed shaft 10, the rotating member 1
2. Although each component of the impeller 14 and the impeller 14 are made of different materials, since the windmill can be easily disassembled, it is easy to separate the different materials, and it is very convenient to reuse resources. is there.
