本発明ハ、繊維強化樹脂製ステアリングホイール等の繊
維強化樹脂構造体における窓部分となり、回転力伝達部
との接合に用いられる部材に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention (c) relates to a member that becomes a window portion in a fiber reinforced resin structure such as a fiber reinforced resin steering wheel and is used for joining with a rotational force transmitting part. be.

としたステアリングホイールも試みられている。(Prior Art) In recent years, rotational force transmitting parts such as steering wheels for automobiles and the like have been made of synthetic resin to reduce weight. In this case, in order to compensate for the lack of strength of the synthetic resin material, attempts have been made to use steering wheels made of P&fiber reinforced resin, which is made by impregnating continuous long fiber bundles of glass fiber, carbon fiber, etc. with polyester resin, epoxy resin, etc. There is.

転軸用取付部となるインサート金具を嵌合接着している
。When the rotational force transmission parts such as the above-mentioned steering wheel are made of fiber-reinforced resin, the fiber-reinforced resin structure is generally hardened and molded and then subjected to post-processing such as machining to form an insert metal fitting that becomes the mounting part for the rotating shaft. are mated and glued.
（発明が解決しようとする問題点）
しかし、このような方法では、後加工によって強化繊維

が高く、衝撃等に対する信頼性に欠ける。(Problems to be Solved by the Invention) However, in such a method, the reinforcing fibers are cut during post-processing, so the mechanical strength of the joint of the fiber-reinforced resin structure is reduced. Furthermore, since an adhesive is used for joining with the metal insert, there is a high degree of dependence on the adhesive strength of the adhesive, resulting in a lack of reliability against impacts and the like.
そこで本発明者等は先に、断面非円形のボス金具に樹脂
含浸連続繊維束を巻き付けて一体結合する方法を提案し
た（特願昭５９−１２３４４５号）。Therefore, the present inventors previously proposed a method of wrapping a resin-impregnated continuous fiber bundle around a boss metal fitting having a non-circular cross section and integrally bonding the same (Japanese Patent Application No. 123445/1982).
しかし、この接合方法でに繊維強化樹脂構造体とボス金
具との接合強度が不足するため、使用に伴ない前記構造
体とボス金具との間に微小りリアランスが生じ、この遊
び（ガタ）に起因して十分なトルク伝達力が得られない
という問題点がある。However, this joining method lacks the bonding strength between the fiber-reinforced resin structure and the boss metal fitting, so a slight clearance occurs between the structure and the boss metal fitting during use, and this play (backlash) occurs. Therefore, there is a problem that sufficient torque transmission force cannot be obtained.
本発明は上記問題点に鑑み、ステアリングホイール芯材
用ボス金具などの接合部材とこれに巻付けられる繊維束
との接合強度を高めることにより、トルク伝達の信頼性
向上を図ろうとするものである。In view of the above problems, the present invention aims to improve the reliability of torque transmission by increasing the bonding strength between a bonding member such as a boss fitting for a steering wheel core material and a fiber bundle wound around the bonding member. .
（問題点を解決するための手段）

をなす手段を設ける。The fiber-reinforced resin structure according to the present invention is a component to which rotational force is transmitted, such as a steering wheel, roller, caster, gear, or IJ, and the joining member constitutes a boss portion of the structure. The cross-sectional shape of the wound portion of the joining member is preferably non-circular, for example, elliptical, and has a width across flats rather than a circle. This is because the adhesion force of the wrapped fist of Kuwaishu increases. At both ends of the winding section, a means having a function similar to that of a seven-lunge section or a hole is usually provided so that the fiber bundle can be easily laminated to a predetermined thickness.

大する。(Function) In the present invention, the resin-impregnated continuous fiber bundle is entirely wrapped around the satin-like surface of the joining member and integrally bonded. Therefore, since the surface of the winding part is formed in a finely uneven shape, the adhesion area increases accordingly, and an anchor effect for the resin occurs throughout the whole winding part, and the synergistic effect of both of these causes the fiber The bonding strength between the reinforced resin structure and the bonding member increases significantly.

接合強度に左右されず信頼性が向上する。In the present invention, there is no need for post-processing, so there is no cutting of UL or fiber bundles.゛Furthermore, since no adhesive is required, reliability is improved regardless of the bonding strength of the adhesive.

The boss metal fitting 1 was fixed to a rotating shaft 6, and while rotating the rotating shaft 6, the resin-impregnated continuous fiber bundle 4 was continuously supplied and wound around the outer circumferential groove 5aK to form a ring portion of a steering wheel core material.

。In addition, the ratio of products with backlash refers to the percentage (ch) of products with backlash relative to all products. As is clear from the figure, in this example where the surface roughness was set to 30 to 100 μm, 30 to 9
・Even when a transmission torque of m was applied, there was no problem with no play occurring between the steering wheel core material and the boss metal fitting. This is because by setting the roughness of the winding surface to 30 μm, the bonding strength of the fiber bundle to the boss fitting was increased due to an increase in the bonding area and an anchor effect.

There was no play between the metal fittings and the steering wheel core material.
