いる。 Reference numeral 1 denotes a cylindrical boss that is fitted into a steering shaft, and the inner ends of a pair of rod-shaped spoke core metals 2 are welded to this boss 1. Furthermore, an annular rim core metal 3 having the boss 1 at its center is welded to the outer ends of these spoke core metals 2. and,
These core metals 2 and 3 are covered with coatings 5 and 6, respectively, and a horn switch mechanism 4 is disposed on the top of the boss 1, so that the boss portion 7, spoke portions 8, and rim portion 9 of the steering wheel are connected to each other. It is configured.

かれている。 Further, a soft member 10 is disposed on the inner peripheral side of the rim core metal 3 so as to form a substantially circular cross section with the rim core metal 3. That is, the soft member 10 is molded with both edges of the rim core metal 3 embedded in the soft member 10 and with the outer peripheral surface of the rim core metal 3 exposed from the soft member 10. ing. Note that this soft member 10 is cut out at the joint between the rim core metal 3 and the spoke core metal 2.
また、上記リム部９の被覆体６は、発泡ウレタ

リングホイールの操作時に安定感が得られる。 Then, when the driver grips the rim portion 9 with his/her hand, the palm of the hand hits the outer circumferential side of the rim portion 9 and the fingertips touch the inner circumferential side of the rim portion 9. At this time, on the outer peripheral side of the rim portion 9, the rim core metal 3 is directly joined to the inner side of the covering 6, so that the rim portion 9 feels hard to the touch. Therefore, when the palm of the hand touches the outer circumferential side of the rim portion 9, which has a hard feel, a sense of stability can be obtained when operating the steering wheel.

により、長距離の運転などに際して疲労が少なく
なる。 Furthermore, on the inner circumferential side of the rim portion 9, the covering 6 and the rim core bar 3 are separated from each other, and a soft member 10 that is softer than the covering 6 is interposed between them, so that the rim part 9 has flexibility and a good feel. becomes soft. As described above, the soft palm of the hand touches the outer circumferential side of the rim part 9, which has a hard feel, and the hard fingertips touch the inner circumferential side of the rim part 9, which has a soft feel, so the rim part 9 feels good when gripped. . Therefore, by providing stable operability and a good feel, fatigue is reduced during long-distance driving.

しやすく、かつ、第４図に示すように、リム芯金
３とスポーク芯金２との連結もしやすい。 In addition, since the rim core metal 3 has a shape in which the central part of the cross section is depressed toward the outer circumference, it is easy to manufacture when forming the rim core metal 3 into a ring shape along the shape of the rim part 9. As shown in FIG. 4, the rim core metal 3 and the spoke core metal 2 can be easily connected.

すればよい。 In the above embodiment, the rim core metal 3 has a substantially semicircular cross section, but the rim core metal 3 is not limited to this shape, and may have a substantially U-shaped cross section as shown in FIG. However, as shown in FIG. 6, the cross section may be substantially L-shaped. Also, the seventh
As shown in the figure, the rim core metal 3 may be embedded in the soft member 10. The point is that the center section of the rim core metal 3 is concave toward the outer circumference, and
The soft member 10 may be disposed on the inner peripheral side of the rim core metal 3 so as to form a substantially circular cross section with the rim core metal 3.
また、第６図に示すように、リム芯金３の内周

てもソフトな感触が得られる。 Further, as shown in FIG. 6, the concave surface on the inner circumferential side of the rim core bar 3 is directed slightly upward, so that the covering body 6 does not directly oppose the rim core bar 3 on the upper surface side of the rim portion 9. You can. By doing so, when the user grips the rim portion 9, a soft feel can be obtained even on the upper surface side of the rim portion 9 where the thumb touches.

According to the present invention, the rim core metal has a shape in which the central part of the cross section is depressed toward the outer periphery, and a soft member that is softer than the covering made of soft synthetic resin of the rim portion is provided on the inner periphery of the rim core metal. As a result, the rim core metal has sufficient impact resistance and is lightweight, and when you grip the rim, it feels harder on the outer periphery and softer on the inner periphery. Therefore, the soft palm of the hand hits the outer circumference of the rim, giving a sense of stability when operating the steering wheel, and the hard fingertips touch the inner circumference of the rim, giving a good feel when gripping the steering wheel. In addition, since the rim core metal has a shape in which the central part of the cross section is concave toward the outer circumference, it is easy to manufacture when forming the rim core metal into a ring shape along the rim shape, and the rim core metal Connection with the spoke core metal can also be made easier.
