【発明の詳細な説明】 〔産業上の利用分野〕 本発明は長繊維強化樹脂製ステアリングホイール芯の製
造方法に関するものである。TECHNICAL FIELD The present invention relates to a method for manufacturing a steering wheel core made of long fiber reinforced resin.
最近、自動車等の車両は軽量化が求められており、その
ため、車両部品であるステアリングホイールの軽量化が
図られている。例えばステアリングホイールを合成樹脂

料を併用して成形する方法が用いられている。しかし、
金属材料を多量に用いた場合には軽量効果は小さくな
る。Recently, the weight of vehicles such as automobiles has been required to be lighter. Therefore, the weight of a steering wheel, which is a vehicle component, has been reduced. For example, a steering wheel is manufactured using a synthetic resin material. However, since the strength is insufficient with only a resin material, a method of molding a metal material together as a reinforcing core material is used. But,
When a large amount of metal material is used, the light weight effect becomes small.

られ、種々の方法が提案されている。Therefore, a resin-impregnated continuous long fiber bundle in which a synthetic resin such as unsaturated polyester resin or epoxy resin is impregnated into a fiber bundle of continuous long fibers such as glass fiber and carbon fiber is wound around a predetermined mold and laminated. Attempts have been made to manufacture a steering wheel by using a steering wheel core made of a long fiber reinforced resin, which is manufactured by curing, as a core material, and various methods have been proposed.

が提案されている。For example, in manufacturing the long-fiber-reinforced resin steering wheel core 10 as shown in FIG. 3, a robot is used to apply a resin-impregnated continuous length to a winding jig having a groove portion corresponding to the shape of the ring portion 11 formed on the outer periphery. After the fiber is wound and only the ring part is wound a predetermined number of times, the fiber is wound around the boss metal fitting 14 arranged on the central axis of the winding jig from the ring part side and returned to the ring part side again. Along a predetermined length, and a series of procedures for winding the boss fitting 14 from another position of the ring portion is repeated a predetermined number of times to wind the ring portion-spoke portion-boss portion, or only the ring portion. The ring portion, the spoke portion 12, and the boss portion 1 are performed by alternately performing the winding and the winding of the ring portion-spoke portion-boss portion
It is proposed to form and stack 3 and then to cure.

問題がある。However, as described above, after only the ring part is wound by the robot with one system of resin-impregnated long fibers,
The ring part-spoke part-the boss part is wound, or the ring part alone and the ring part-spoke part-the boss part are alternately wound to form a steering wheel core ring part,
When forming the spoke portion and the boss portion, there is a problem that the winding time of the steering wheel core is not short.

に行うことを特徴とするものである。Method for manufacturing long-fiber-reinforced resin steering wheel core according to the present invention: A resin-impregnated long fiber is wound around a winding jig that rotates in one direction to wind only a ring portion, and on the center axis of the winding jig. The resin-impregnated long fiber is hung from the ring portion side around the outer periphery of the boss member that is attached and rotates integrally with the winding jig, and is returned to the ring portion side again. The ring part-spoke part-is made to match the winding direction of only the ring part by performing a series of procedures for winding the wire around the boss member from another position of the ring part, and repeating the sequence in sequence.
When the long fiber-reinforced resin steering wheel core is manufactured by integrally winding the boss part and then curing it, the fiber and ring part that surrounds only the ring part-spoke part-
The fiber wound around the boss is a different type of fiber, and the ring-
The spoke portion-boss portion is wound by using a robot, and in parallel with that, only the ring portion is wound without using the robot.
