PROBLEM TO BE SOLVED: To provide a suspension cross member which prevents the deviation of a relative position with an arm member, and avoids snow damage.SOLUTION: A suspension cross member for coupling an arm member 10 supporting an axle and a vehicle body includes: an upper plate 2 disposed above the arm member 10 and supported on the vehicle body; a lower plate 3 disposed under the arm member 10 and supported on the vehicle body; and a bush 20 which fixes an outer cylinder 22 to the arm member 10, is internally fitted with an elastic member 23 inside, and coupled with the upper plate 2 and the lower plate 3 through an inner cylinder 21 internally fitted inside. The inner cylinder 21 has an intermediate portion 21b sandwiched between the upper plate 2 and the lower plate 3, and a lower end portion 21c formed to have a smaller diameter than the intermediate portion 21b and penetrating the lower late 3. A spring groove 21p is formed on an inner peripheral surface of the intermediate portion 21b, and a screw thread 21r is formed on an outer peripheral surface of the lower end portion 21c.SELECTED DRAWING: Figure 4
【課題】アーム部材との相対位置のずれを防止し、雪害をも回避したサスクロスを提供する。【解決手段】車軸を支えるアーム部材10と車体とを連結するサスクロスが、アーム部材10の上方に配置され車体に支持されるアッパプレート2と、アーム部材10の下方に配置され車体に支持されるロアプレート3と、アーム部材10に外筒22を固定され、その内側に弾性部材23を内嵌されるとともに、その内側に内嵌された内筒21を介してアッパプレート2とロアプレート3とに連結されるブッシュ20と、を備える。内筒21は、アッパプレート2とロアプレート3とに挟持される中間部21bと、中間部21bよりも小径に形成されてロアプレート3を貫通する下端部21cとを有し、中間部21bの内周面にねじ溝21pが形成されるとともに、下端部21cの外周面にねじ山21rが形成される。【選択図】図4
