化させたものである。In recent years, steering wheels, which are mainly installed on vehicles such as automobiles and small vessels such as motorboats, are made of fiber-reinforced resin (hereinafter referred to as FRP-fiber) in order to reduce weight and increase strength.
In practical use, a core material formed by laminating layers using reinforced plastic (hereinafter referred to as "reinforced plasHcs-") is surface-treated with a surface material such as leather or leather. The FRP is made by impregnating continuous long fiber bundles of glass fibers, carbon fibers, etc. with a synthetic resin, such as polyester resin, epoxy resin, etc., winding them around a predetermined mold and laminating them, and curing the synthetic resin. It is.

１４とからなる。The conventional manufacturing method for steering wheel core material is as follows:
For example, there is a method using a winding jig shown in FIG. In the winding jig, a rim molding die 1 is formed by assembling circular arc parts 5, 4, and 5 to a disc-shaped base 2.
A main shaft 6 passes through the center of the main shaft 6, and the base 2 is fixed near the tip of the main shaft 6. By assembling each part of the rim mold 1, a groove 7 having a substantially semicircular cross section is formed on the outer periphery, and a continuous filament bundle 9 impregnated with resin is formed between the groove 7 and the hub fitting 8. After being rolled and laminated, the steering wheel core material 10 is obtained by heating and curing. In addition, 1 in the figure
1 is a guide bin. Further, the arrow mark indicates the moving direction of the continuous long fiber bundle 9, and the arrow B indicates the rotating direction of the main shaft 6. FIG. 7 is a side view of FIG. 6 viewed from direction C, and the steering wheel core 10 is composed of a rim portion 12, a hub portion 13, and spoke portions 14.

品の寸法合格率低下の原因となっていた。FIG. 8 shows an enlarged view of the part (2) surrounded by a broken line in FIG. 7. As is clear from the figure, when the conventional manufacturing method is used, the end of the rim portion 12 protrudes outward, which causes fringing. Furthermore, the dimensional accuracy of the rim portion 120 is poor, and air bubbles cannot be removed. In particular, when winding the continuous long fibers 9 by placing a bottle at the branching part between the rim part 12 and the spoke part 14, the branching part may swell too much and may not fit within the specified (designed) dimensions, resulting in the product's dimensions being passed. This was the cause of the rate decline.

。In other words, the method for manufacturing the steering wheel core material of the present invention involves forming a resin-impregnated continuous fiber bundle into a rim forming mold.
・The continuous long fiber bundle is wound on a winding jig equipped with a metal fitting to form a steering wheel core material consisting of a rim portion, a knob portion, and a spoke portion. is characterized in that the outer peripheral surface of the rim portion is formed by pressing the rim portion along the outer periphery of the rim portion toward the center thereof with a roller.

て用いるのが望ましい。As for the material of the loan, it is preferable to use one or a combination of materials such as metal with a chromium-plated surface, polytetrafluoroethylene resin, ceramic, etc., which are difficult to adhere to resin on the surface and have low abrasion resistance.

なるものが挙げられる。回転部の中央部にはベアリング
などを設けて回転抵抗を少なくするとよい。Examples of the roller include a roller that includes a rotating part and a support part for the rotating part. It is preferable to provide a bearing or the like in the center of the rotating part to reduce rotational resistance.
ローラは連続長繊維束を巻取治具に巻取りながら使用す
るのが好ましわが、巻取った後に再度使用して外形を整
えてもよい。The roller is preferably used while winding the continuous filament bundle onto a winding jig, but it may also be used again after winding to adjust the outer shape.
ローラを使用する場合は手動で行ってもよいが、連続繊
維束の巻取と連動させて自動化すると作業効率が向上し
