PROBLEM TO BE SOLVED: To provide a height adjustment device including a transverse pipe, where the transverse pipe has two end-side support regions, these support regions migrates to a larger diameter in a diameter step within an intermediate region, in that case, link members are non-rotatably mounted in the support regions respectively, and the height adjustment device requires a small amount of material and can be easily manufactured.SOLUTION: A diameter step part between an intermediate region 9.2 and a support regions 9.1 is formed by a tapered abutment face 17 of a transverse pipe. Link members 8 are also axially secured even in the other direction of the transverse pipe. In that case, at least one axial groove is formed in a support hole, and material is configured to flow into the groove during a production process for non-rotatably securing the link members 8 in the transverse pipe by cold deformation of adjacent ends of the intermediate region 9.2.SELECTED DRAWING: Figure 3

    【課題】横方向パイプを有し、この横方向パイプが、2つの端部側の支持領域を備え、これら支持領域が、中間領域内における直径段部において、より大きな直径に移行し、その際、前記支持領域に、それぞれに、回転不能に、連接部材が装着されている。少量の材料を要して、且つ、容易に製造され得る高さ調節装置を提供する。【解決手段】中間領域9.2と支持領域9.1との間の直径段部が、横方向パイプのテーパー状の当接面17によって形成されており、連接部材8が、軸線方向に他方の方向においても、固定されており、その際、支持孔内において、少なくとも1つの軸線方向の溝部が形成されており、前記溝部内へと、製造プロセスにおいて、前記中間領域9.2の隣接する端部の冷間変形によって、材料が、前記横方向パイプにおける前記連接部材8の回転不能な固定のために、流れ込ませられている。【選択図】図3
