孔６は全長に亘って同径であり、筒部２は釘１に対して
全長に亘って密着状に外嵌されていた。<Conventional technology> In pinball game machines such as pachinko machines, arrangement ball game machines, and mahjong ball machines, a windmill is rotatably attached to the game board surface using nails, and the windmill is used to launch wind onto the game board surface. The falling direction of the game ball is changed. By the way, as shown in FIGS. 12 and 13, this type of windmill has a cylindrical portion 2 into which the nail l is rotatably inserted, and a plurality of blade portions 3 that protrude radially from the outer periphery of the cylindrical portion 2. Some wind turbines are equipped with a blade body 4 and a flange body 5 protruding from the axially outer end of the cylindrical portion 2 of the blade body 4. Conventional wind turbines of this type have a structure as shown in the figure. Since the wing body 4 and the flange body 5 were integrally formed of synthetic resin or the like, the insertion hole 6 for inserting the nail 1 in the cylindrical part 2 had a full length to enable molding during molding. The cylindrical portion 2 had the same diameter throughout, and the cylindrical portion 2 was fitted onto the nail 1 in a tight manner over its entire length.
〈考案が解決しようとする課題〉従来は、風車の翼体４の筒部２が釘１に対して全長に亘
って密着状に外嵌されているため、遊技球の流れを変更

内壁の一部が釘１に対して強く圧接してしまい、これが
ために風車かた易く回動不能になり、風車の機能を果た
せなくなるという問題があった。<Problem to be solved by the invention> Conventionally, since the cylindrical part 2 of the blade body 4 of the wind turbine was tightly fitted over the entire length of the nail 1, it was difficult to change the flow of the game ball, etc. If the nail 1 is bent as shown by the chain line, a part of the inner wall of the cylindrical part 2 will come into strong pressure contact with the nail 1, which will make the windmill hard and unable to rotate, making it unable to perform its function. There was a problem.
本発明は上記問題点に鑑み、釘が多少弯曲しても、風車
のスムーズ回転を保持し得るようにしたものである。In view of the above-mentioned problems, the present invention is designed to maintain smooth rotation of a wind turbine even if the nails are somewhat curved.

The wing body 21 has a cylindrical portion 23 and a plurality of wing portions 24 that protrude radially from the outer periphery of the cylindrical portion 23, and a flange body 22 that protrudes from the axially outer end of the cylindrical portion 23 of the wing body 21. In the windmill of a pinball game machine, the wing body 21 and the flange body 22 are constructed separately, and are connected and fixed to each other via an engagement mechanism 25 provided between the wing body 21 and the flange body 22. A fitting part 34 is provided at the center of the flange body 22 and is rotatably fitted to the outside of the nail 20 in a tight manner. is provided with a fitting part 35 that is rotatable and tightly fitted onto the nail 20, and a fitting part 35 that is loosely fitted onto the nail 20 is provided on the side of the collar body 22 from the opposite end of the cylindrical part 23. The point is that a loose fitting portion 36 that fits externally is provided.

A fitting part 35 is provided at the end opposite to the collar body 22 and is rotatable and tightly fitted onto the nail 20, and is located closer to the collar body 22 than the opposite end of the cylindrical part 23. Since the nail 20 is provided with a loose fitting part 36 that fits loosely into the nail 20, the wind turbine is rotatably supported with respect to the nail 20 only at both ends in the axial direction, and the wind turbine is supported at both ends in the axial direction and at the center side of the wind turbine. Since a gap is formed between the nail 20 and the nail 20, even if the nail 20 is slightly bent, the inner wall of the cylindrical portion 23 will not come into strong pressure contact with the nail 20, allowing the windmill to rotate smoothly. This allows the wind turbine to maintain its functionality over a long period of time.
