To make it possible to achieve both decreased torsion rigidity and maintained durability.SOLUTION: An arm member has at least one or more notches such that the center axis of an arm member and a load axis of the arm member coincide. The center axis of the arm member is an axis connecting, in the axial direction of the arm member, the respective centers of the shapes of cross-sections taken by cutting the arm member with a plane perpendicular to the axis of the arm member. The load axis of the arm member is an axis along which load is applied to the arm member.SELECTED DRAWING: Figure 1
【課題】ねじり剛性の低減と耐久性の維持を両立できること。【解決手段】アーム部材の中心軸と、アーム部材の荷重線と、が一致するように、アーム部材には少なくとも1つ以上の欠肉部が形成されている。アーム部材の中心軸は、アーム部材をアーム部材の軸に垂直な面によって切断した際の各断面形状の図心をアーム部材の軸方向に繋げた線である。アーム部材の荷重線は、アーム部材において荷重がかかる線である。【選択図】図1
