Recently, as automobiles have become lighter, steering wheels have also been manufactured using synthetic resin materials such as polyurethane resin and polypropylene resin. However, using a metal material such as an iron rod or an iron pipe as a reinforcing body has little weight reduction effect and is also disadvantageous against vibration.

Attempts have been made to manufacture steering wheels with high strength.

ホイールとしても強度、剛性に問題があつた。 For this purpose, for example, a winding jig 1 as shown in FIG. 1 is used, and jigs 5 and 6 are used to form ring portions by rolling the resin-impregnated continuous fibers in the order of the arrows shown in the figure. The reinforcing body 2 as shown in FIG. 7 is obtained by winding it around the boss metal fitting 4 a predetermined number of times. The base portions of the spoke portions 3 of the body 2 are separated, and the cross section taken along the line B-B in the figure has a bifurcated shape as shown in FIG. Even when such a reinforcing body is coated with resin and used as a steering wheel, there are problems in terms of strength and rigidity.

The inventors placed a winding jig at a predetermined position centering on the boss metal fitting, and wound the resin-impregnated continuous fibers around the boss metal fitting and the winding jig to form the ring part and the sub-ring part into spokes. A reinforcing body is formed by connecting the boss metal fittings to the spoke part, and then the resin-impregnated fiber bundle of the spoke part is caulked with a tightening tool such as a collar ring, and after being squeezed into a fiber bundle with a circular cross section, the reinforcing body is heated and hardened. Furthermore, we decided to cover it with a resin layer and perform heat and pressure molding.

The continuous fibers used in the present invention are carbon fibers with a thickness of about 7 μm, and glass fibers with a thickness of 13 to 25 μm, and are made by twisting or twisting 2,000 to 30,000 rovings. Straight threads or cords (roving or yarn) are used. The composition of the resin liquid impregnated into these threads or strings has a viscosity that sufficiently spreads over the surface of the fibers when impregnated but does not run off, and a special catalyst or accelerator is added to achieve coloring. It is preferable that a certain degree of hardening progresses when caulked with a coloring method, and the cross-sectional shape imparted by coloring can be maintained.

However, it is preferable to use one that has a certain degree of elasticity and can automatically tighten the resin-impregnated fiber bundle when worn.

6 and spacers 7, 7 are arranged. Jig 5,
6 is a semicircular cross-sectional view taken along the line A--A in the figure, as shown in FIG. In this arrangement, the resin-impregnated fibers are wound around the grooves of the spacer 7, then around the grooves of the boss fitting 4 in the direction of the dashed-dotted arrow, and then wrapped around the grooves of the boss fitting 4 along the jigs 5 and 6. Deing. By repeating such winding several times, a reinforcing body 2 in which spoke portions 3, ring portions 8, and sub-ring portions 9 are combined as shown in FIG. 7 is obtained.

(実施例)を得る。 Next, aluminum collar rings 10 with a thickness of 1 mm as shown in FIG. 4 are attached to both ends of the spoke portions 3 as shown in FIG. As shown in Figure 5, the cross section approaches a perfect circle. At this time, the resin liquid is squeezed out and at the same time, the air present within the fibers is pushed out. So coloring 10
If the color ring 10 is attached, or if the bundled state can be maintained, heat treatment at 120℃ for 2 hours will increase the fiber volume content to 40 or more.
50% reinforcement is obtained. Further, this reinforcing body is coated with urethane resin to obtain a steering wheel (example).

That is, the steering wheel 1 shown in FIG.
When a load of 50 kg is applied to the position a of the ring 12 in a direction perpendicular to the plane of the paper with the boss portion 4 of 1 fixed, the amount of deflection in the example is 29 mm, while the amount of deflection in the comparative example is 60 to 70 mm. indicated the amount. Also, as shown in FIG. 6, when the ring 12 is cut at positions b and c near the spokes and the separated spokes 13 are twisted by 20 degrees, the torque in the embodiment is 32 to 33 Nm. On the other hand, in the comparative example, it was 17 Nm. From these test results, it is clear that the steering wheel manufactured by the method of the present invention has significantly better torsional characteristics than those manufactured by the conventional method.
