　上述の車両用のアーム部品によれば、被取付部材が取り付けられる取付部は、軸方向に対して直交する方向から視て波形状を有するため、軸方向において同一の位置で取り付けられる場合と比較して、軸方向の取付け幅が広がる。したがって、板厚を増やすことなく、被取付部材が取り付けられる位置における剛性を高めることができる。よって、製造コストが増大することなく、被取付部材が取り付けられる位置における剛性を高めることのできる車両用のアーム部品を提供することができる。 According to the above-described vehicle arm part, the mounting portion to which the mounted member is mounted has a wave shape when viewed from the direction orthogonal to the axial direction, so that it is compared with the case where the mounting portion is mounted at the same position in the axial direction As a result, the axial mounting width increases. Therefore, the rigidity at the position where the attached member is attached can be increased without increasing the plate thickness. Therefore, it is possible to provide a vehicle arm component that can increase the rigidity at the position where the attached member is attached without increasing the manufacturing cost.

　リアクロスメンバ４０は、下方に２つのリンク取付部４１，４２を有する。リンク取付部４１，４２には不図示のサスペンションリンクがボルト、ナットによって締結される。そして、サスペンションリンクのリンク取付部４１，４２が取り付けられる側の反対側には、ナックルやハブなどのアクスル系部品が接続される。 The rear cross member 40 has two link mounting portions 41 and 42 below. A suspension link (not shown) is fastened to the link attachment portions 41 and 42 by bolts and nuts. An axle system component such as a knuckle or a hub is connected to the opposite side of the suspension link where the link attachment portions 41 and 42 are attached.
　次に、取付部１１ａ，１１ｂ，２１ａ，２１ｂの構成について詳述する。取付部１１ａと取付部２１ａとは左右対称に形成される。また、取付部１１ｂと取付部２１ｂとは左右対称に形成される。よって、ここでは取付部２１ａ、２１ｂの構成の説明は省略し、取付部１１ａ，１１ｂの構成について説明する。 Next, the configuration of the mounting portions 11a, 11b, 21a, and 21b will be described in detail. The attachment part 11a and the attachment part 21a are formed symmetrically. Moreover, the attachment part 11b and the attachment part 21b are formed symmetrically. Therefore, description of the structure of the attachment parts 21a and 21b is omitted here, and the structure of the attachment parts 11a and 11b will be described.
　取付部１１ａは、車両の上下方向から視てカラー１２の外周に沿う形状を有し（図３参照）、車両の側面方向から視て波形状Ｗ１，Ｗ２を有する（図４参照）。波形状Ｗ１，Ｗ２は、図４に示すように、１つの山状によって形成される。取付部１１ａは、カラー１２の周方向の一部を覆うように構成され、取付部１１ａにおいて溶接することによって、カラー１２が取付部１１ａに取り付けられる。 The mounting portion 11a has a shape along the outer periphery of the collar 12 when viewed from the vertical direction of the vehicle (see FIG. 3), and has wave shapes W1 and W2 when viewed from the side of the vehicle (see FIG. 4). The wave shapes W1 and W2 are formed by one mountain shape as shown in FIG. The attachment portion 11a is configured to cover a part of the collar 12 in the circumferential direction, and the collar 12 is attached to the attachment portion 11a by welding at the attachment portion 11a.
　カラー１２は、図４に示すように、車両の上下方向に沿って２箇所で取り付けられ、車両上側における波形状Ｗ１及び車両下側における波形状Ｗ２は、車両の上下方向から視て周方向の異なる位置に形成される（図３参照）。 As shown in FIG. 4, the collar 12 is attached at two locations along the vertical direction of the vehicle. The wave shape W1 on the upper side of the vehicle and the wave shape W2 on the lower side of the vehicle are circumferentially viewed from the vertical direction of the vehicle. They are formed at different positions (see FIG. 3).
　波形状Ｗ１は、図５に示すように、カラー１２の外周から離れるにつれてなだらかに下降するように形成される。また、図示は省略するが、波形状Ｗ２は、波形状Ｗ１と同様に、カラー１２の外周から離れるにつれてなだらかに下降するように形成される。また、波形状Ｗ１，Ｗ２は、互いに離間する方向に山状が形成される。しかしながら、一方が離間する方向に、または互いに近づく方向に山状が形成されてもよい。 As shown in FIG. 5, the wave shape W <b> 1 is formed so as to gently fall as the distance from the outer periphery of the collar 12 increases. Although not shown, the wave shape W2 is formed so as to gently fall as it moves away from the outer periphery of the collar 12, similarly to the wave shape W1. Further, the corrugations W1 and W2 are mountain-shaped in a direction away from each other. However, a mountain shape may be formed in a direction in which one of them is separated or in a direction in which they approach each other.
　取付部１１ｂは、車両の上下方向の上側にのみ波形状Ｗ３（図１，図２参照）が設けられている点において、取付部１１ａの構成と異なり、波形状Ｗ３は、波形状Ｗ１，Ｗ２と同様の構成を有する。 The mounting portion 11b differs from the configuration of the mounting portion 11a in that the wave shape W3 (see FIGS. 1 and 2) is provided only on the upper side in the vertical direction of the vehicle. It has the same configuration as.
　以上説明したように、第１実施形態に係る車両用のアーム部品は、車両の上下方向に伸延するカラー１２が取り付けられるサスペンションのサブフレーム１のサイドメンバ１０であって、カラー１２が取り付けられる取付部１１ａは、車両の上下方向から視てカラー１２の外周に沿う形状を有し、車両の上下方向に対して直交する方向から視て波形状Ｗ１，Ｗ２を有する。このため、車両の高さ方向において同一の高さで取り付けられる場合と比較して、車両の高さ方向の接合幅Ｈが広がる。したがって、板厚を増やすことなく、カラー１２が取り付けられる位置における剛性を高めることができる。よって、製造コストが増大することなく、カラー１２が取り付けられる位置における剛性を高めることができる。 As described above, the vehicle arm component according to the first embodiment is the side member 10 of the subframe 1 of the suspension to which the collar 12 extending in the vertical direction of the vehicle is attached, and the attachment to which the collar 12 is attached. The portion 11a has a shape along the outer periphery of the collar 12 when viewed from the vertical direction of the vehicle, and has wave shapes W1 and W2 when viewed from a direction orthogonal to the vertical direction of the vehicle. For this reason, compared with the case where it attaches with the same height in the height direction of a vehicle, the joining width H of the height direction of a vehicle spreads. Therefore, the rigidity at the position where the collar 12 is attached can be increased without increasing the plate thickness. Therefore, the rigidity at the position where the collar 12 is attached can be increased without increasing the manufacturing cost.
　また、波形状Ｗ１，Ｗ２は、１つの山状によって形成される。このため、簡易な構造の型によって波形状Ｗ１，Ｗ２を形成することができる。さらに波形状の周期を大きくすることができ、応力集中が生じにくい。 Also, the wave shapes W1, W2 are formed by one mountain shape. For this reason, the wave shapes W1 and W2 can be formed by a mold having a simple structure. Furthermore, the waveform period can be increased, and stress concentration hardly occurs.
　また、カラー１２は車両の上下方向に沿って２箇所で取り付けられ、車両の上側の位置における波形状Ｗ１及び車両の下側の位置における波形状Ｗ２は、上下方向から視て周方向の互いに異なる位置に形成される。したがって、運転時にカラー１２に作用する任意の方向からの入力に対して、強度を向上することができる。 The collar 12 is attached at two locations along the vertical direction of the vehicle, and the waveform W1 at the upper position of the vehicle and the waveform W2 at the lower position of the vehicle are different from each other in the circumferential direction when viewed from the vertical direction. Formed in position. Therefore, the strength can be improved with respect to an input from an arbitrary direction acting on the collar 12 during operation.
　また、取付部１１ａは、カラー１２の外周の周方向の一部を覆うように構成され、取付部１１ａにおいて溶接することによって、カラー１２が取付部１１ａに取り付けられる。このため、サイドメンバ１０の材料を少なくすることができ、軽量化を図ることができる。 Further, the attachment portion 11a is configured to cover a part of the outer periphery of the collar 12 in the circumferential direction, and the collar 12 is attached to the attachment portion 11a by welding at the attachment portion 11a. For this reason, the material of the side member 10 can be reduced and weight reduction can be achieved.

　貫通孔２Ａは、図７に示すように、周方向の一部において波形状Ｗ４を有する。この構成によれば、圧入方向における圧入幅が広がるため、ブッシュが取り付けられる位置における剛性を高めることができる。 As shown in FIG. 7, the through-hole 2A has a wave shape W4 in a part in the circumferential direction. According to this configuration, since the press-fitting width in the press-fitting direction is widened, the rigidity at the position where the bush is attached can be increased.
　以上説明したように、第２実施形態に係る車両用のアーム部品であるサスペンションアーム２では、取付部は、ブッシュの外周の周方向の全体を覆う貫通孔２Ａ，２Ｂに構成され、ブッシュを取付部に圧入することによって、ブッシュが取付部に取り付けられる。この構成であれば、圧入方向における圧入幅が広がるため、ブッシュが取り付けられる位置における剛性を高めることができる。 As described above, in the suspension arm 2 that is the vehicle arm component according to the second embodiment, the mounting portion is configured by the through holes 2A and 2B covering the entire circumferential direction of the outer periphery of the bush, and the bush is mounted.
