た。 In general, a steering wheel of an automobile includes a ring-shaped rim portion that serves as a grip portion, and a boss portion that is an attachment portion to the steering shaft.
It is composed of spoke parts that integrally connect the rim part and the boss part. However, in conventional steering wheels, the rim, boss, and spokes are all made of carbon steel, the rim and spokes, and the spokes and bosses are welded, and the rim is made of rubber or plastic. It was molded using a design mold made of steel, and because it was constructed mainly of steel, even the lightest one weighed 2 kg. For this reason, vibrations are generated in the steering wheel, especially when driving at high speeds or on rough roads, reducing operational stability and causing discomfort to the driver, as well as increasing fuel consumption.

Moreover, the object is to provide a steering wheel that is easy to manufacture.

施す。 Embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIGS. 1 and 2, the steering wheel is divided into a rim portion 1, spoke portions 2, and boss portions 3 in a loop shape, and a first core material 4 and a second core material are separated. 5 is made of plastic such as foam material or lightweight shape-retaining material such as rubber. Next, as shown in FIGS. 3 and 4, unidirectional reinforcing fibers 12 made of continuous carbon fibers, alumina fibers, etc. are arranged on the surface of each loop-shaped core material 4, 5 in the longitudinal direction, and diagonally ( almost
45°). Next, as shown in FIG. 5, the unidirectional reinforcing fibers 12 are wound diagonally across the main spoke portion 2 so as to integrate the core materials 4 and 5. 12a is unidirectional reinforcing fiber 1
This is an extension of 2. Next, as shown in FIG. 6, the boss core metal 6 is housed in the hole 3a formed at the center of the boss part 3. An involute serration that engages with a serration of the steering shaft is provided on the inner peripheral surface of the boss core metal 6. Then, as shown in FIG. 7, each unidirectional reinforcing fiber 12 is impregnated with plastic (it may be impregnated in advance) and hardened to form a plastic layer 7, and the boss core 6 is unidirectionally reinforced. Extension portion 12a of fiber 12
The fibers are then molded together with short fibers of unidirectional reinforcing fibers in a plastic mold 8 to be integrated with each spoke portion 2. In reality, a cosmetic mold is further applied.

容易となる。 As described above, the steering wheel according to the present invention is formed mainly from a core material made of a lightweight shape-retaining material and a plastic layer reinforced with unidirectional reinforcing fibers, and is lightweight and resistant to bending and torsional moments. A steering wheel having sufficient strength can be obtained. Therefore, the steering wheel is less likely to vibrate while the vehicle is running, providing better operability and lower fuel consumption. Furthermore, since each core material is loop-shaped, it is extremely easy to arrange the unidirectional reinforcing fibers.
