Description
【考案の詳細な説明】
本考案は車輌用ステアリングホイールに関するものであ
る。[Detailed Description of the Invention] The present invention relates to a steering wheel for a vehicle.
従来この種ステアリングホイールに於て、車輌衝突時等
にはステアリングホイールのリム部とステ一部との接合
部に応力が集中し、該接合部は強度を必要とするものの
接合部以外のリム部には何ら特別な強度を必要としない
にも拘らず、リム部内に挿入される芯金はリム部とステ
一部との接合部及び該接合部以外のリム部にも全周にわ
たり一様の断面積にて成形されていたので、ステアリン
グホイールのコストが高くなるばかりか軽量化をはかる
べく何ら施策されていないものであった。Conventionally, in this type of steering wheel, stress is concentrated at the joint between the rim of the steering wheel and the steering wheel during a vehicle collision, etc., and although this joint requires strength, the stress is concentrated on the rim other than the joint. Although the core metal inserted into the rim part does not require any special strength, it has a uniform strength over the entire circumference at the joint between the rim part and the stem part, and also at the rim part other than the joint part. Since the steering wheel was formed with a cross-sectional area, not only did it increase the cost of the steering wheel, but no measures were taken to reduce its weight.
そこで本考案は前記従来品の欠点を解消するステアリン
グホイールを提供することを目的とする。Therefore, an object of the present invention is to provide a steering wheel that eliminates the drawbacks of the conventional products.
以下本考案の好ましい一実施例を図面に基づいて説明す
る。A preferred embodiment of the present invention will be described below with reference to the drawings.
１０はステアリングホイールを示し、該ステアリングホ
イール１０はリム部１１．ステ一部１２．１２及びボス
部１３とから戊っている。Reference numeral 10 indicates a steering wheel, and the steering wheel 10 has a rim portion 11. It is separated from the stem part 12.12 and the boss part 13.
ステアリングホイール１０はアルミニウム或いはマグネ
シウム等の軽合金ダイカスト製法により成型されるもの
で、リム部１１内にはボス部１３及びステ一部１２．１
２から延在した芯金部１４が挿入されている。The steering wheel 10 is molded by die-casting of a light alloy such as aluminum or magnesium, and the rim portion 11 includes a boss portion 13 and a steering portion 12.1.
A core metal part 14 extending from 2 is inserted.
リム部１１内に挿入される芯金部１４の断面積はステ一
部１２．１２との接合部１５．１５に比較しステ一部１
２．１２との接合部１５．１５から離れると共に徐々に
小さくしている。The cross-sectional area of the core metal part 14 inserted into the rim part 11 is larger than that of the stem part 1 compared to the joint part 15.15 with the stem part 12.12.
It gradually becomes smaller as it moves away from the junction 15.15 with 2.12.
１６はボス部１３に形成された図示せざるシャフトへの
取付孔を示す。Reference numeral 16 indicates a hole for attaching to a shaft (not shown) formed in the boss portion 13.
以上より本考案装置に於ては、ステアリングホイールの
リム部内に挿入される芯金部１４の断面積はステ一部と

一部との接合部に集中する応力に対しても充分抗し得る
実用上すぐれた効果を奏するものである。As described above, in the device of the present invention, the cross-sectional area of the core metal part 14 inserted into the rim part of the steering wheel gradually becomes smaller as it moves away from the joint part with the steer part, compared to the joint part with the steer part. This makes it possible to manufacture the steering wheel at a low cost and reduce its weight.In addition, in the event of a vehicle collision, there is no local pressure change in the core metal part 14, and the steering wheel rim part This has an excellent practical effect of being able to sufficiently withstand stress concentrated at the joint between the steel and the stem part.
