To provide a steering knuckle that employs a structure which does not disrupt weight saving by preventing a plane to be clamped and utilized at the time of manufacturing from becoming an excessive thickness while the rigidity against load applied to a tie rod attaching arm being secured.SOLUTION: A flat recess portion 13 for clamping is formed in a tie rod attaching arm 4 at a side near the input point of load from a tie rod, and a reinforcement portion 12 is provided at a side apart from the input point. Since the reinforcement portion 12 is placed at a location where the moment of force increases, the rigidity against the load applied to the tie rod attaching arm 4 is obtained. By cutting out a part of the arm to provide the recess portion 13 while increasing the cross-sectional area of the tie rod attaching arm 4 for reinforcement, weight saving of a steering knuckle is accomplished while the rigidity of the tie rod attaching arm 4 being secured.SELECTED DRAWING: Figure 1

    【課題】タイロッド取付アームにかかる荷重に対する強度を確保しつつ、製造時に使用するクランプ用の平面が余肉とならないようにして、軽量化を妨げない構造のステアリングナックルを提供する。【解決手段】タイロッド取付アーム4におけるタイロッドからの荷重の入力点に近い側にクランプ用の平坦な凹部13が形成され、入力点から遠い側に補強部12が設けられる。力のモーメントが大きくなる箇所に補強部12が配置されるので、タイロッド取付アーム4にかかる荷重に対する強度が得られる。タイロッド取付アーム4の断面積を増して補強しながら、アームの一部を切り欠いて凹部13を設けることにより、タイロッド取付アーム4の強度を確保しながら、ステアリングナックルの軽量化を実現する。【選択図】図1
