PROBLEM TO BE SOLVED: To realize a structure capable of attaining a crossing connection of another round pipe by a similar connection structure at a side opposite to the specified location at the outer peripheral surface of one round pipe without causing the screw heads of the fastening screws to be exposed at a remarkable location at a round pipe connection structure in which an end surface of the other round pipe is abutted against a specified location at an outer peripheral surface of one round pipe and these round pipes are fastened and connected in their approaching directions by a fastening means using the fastening screws.SOLUTION: One round pipe holds a protrusion protruded out of an outer peripheral surface in an outward direction and this invention is constituted in such a way that an end surface of the other round pipe is pushed against an outer peripheral surface of the aforesaid one round pipe under a state in which a fastening screw engaged in thread with a nut member internally installed in the aforesaid one round pipe from the aforesaid other round pipe and at the same time the outer peripheral surface of the aforesaid other round pipe is pushed against the aforesaid protrusion.SELECTED DRAWING: Figure 20 【課題】一方の丸パイプの外周面における特定箇所に他方の丸パイプの端面を当接させ、それらの丸パイプを締付ねじを用いた緊締手段により相寄る方向に緊締して接続する丸パイプの接続構造において、締付ねじのねじ頭が目立った箇所に露出せず、前記一方の丸パイプの外周面における前記特定箇所と反対側にさらに他の丸パイプを同様な接続構造により直交接続することが可能な構造を実現する。【解決手段】一方の丸パイプが、外周面から外方に突出する凸部を保持したものであり、前記他方の丸パイプ側から前記一方の丸パイプに内設されたナット部材に螺合させた前記締付ねじを締め付けた状態で、前記他方の丸パイプの端面が前記一方の丸パイプの外周面に押し付けられるとともに、前記他方の丸パイプの外周面が前記凸部に押し付けられるように構成されているようにする。【選択図】図２０
