部を介して連結されている。For example, in the case of a trailing arm type rear suspension as disclosed in Japanese Utility Model Laid-Open No. 58-45108, boss portions are provided at the front ends of the left and right arm portions, and each boss portion is provided on the vehicle body side. The suspension arm is connected to the vehicle body by being fitted and supported on the support shaft via a cylindrical rubber bush or the like. On the other hand, a spindle bracket for supporting the wheel is joined to the rear end of the arm portion by welding. Further, the left and right arm portions are connected to each other via a beam portion that extends in the vehicle width direction between them.

し状に設けることによって車幅方向の剛性が高められ、
しかも、上記ビームが捩じり弾性を有するためスタビラ
イザとして機能し、走行安定性を高めることができる。In the trailing arm type rear suspension, the rigidity in the vehicle width direction is enhanced by providing the beam in a straddle shape on the left and right arm portions.
Moreover, since the beam has torsional elasticity, it functions as a stabilizer, and the running stability can be improved.

弾発力が左右のアーム部の上下動を調整することにより
発揮される。By the way, the above-mentioned stabilizer effect occurs when the above-mentioned beam portion hung over the left and right arm portions functions as a so-called torsion spring and is elastically twisted and deformed by the vertical movement of the left and right arm portions. Torsional resilience is exerted by adjusting the vertical movement of the left and right arms.

部に亀裂等が生じて強度上の問題が発生しやすい。However, since the arm portion and the beam portion are joined by welding, when the beam portion is twisted, stress is likely to be concentrated on these joint portions, and cracks or the like are generated at the joint portions, resulting in strength. The above problems are likely to occur.

量化を図ることも困難である。However, in the conventional suspension structure as described in the above publication, a separate connecting member or reinforcing member is required to join the arm portion and the torsion beam. To do. Therefore, the number of parts increases and the manufacturing cost increases. Further, there is a problem that the welding length of the arc welded portion becomes long because the connecting member or the reinforcing member is joined, the number of manufacturing processes increases and the assembling workability deteriorates. Furthermore, it is difficult to reduce the weight of the vehicle body by increasing the weight.
