CONNECTION STRUCTURE FOR TUBULAR MEMBERS

To provide a technique capable of suppressing deformation of a first tubular member and a second tubular member when the first tubular member and the second tubular member are connected.SOLUTION: A connection structure for tubular members comprises: a first tubular member; a second tubular member which is disposed in parallel with the first tubular member, the second tubular member being disposed in such a manner that its axial direction coincides with an axial direction of the first tubular member; a pressing member which is disposed between the first tubular member and the second tubular member, the pressing member pressing the first tubular member and the second tubular member in a direction in which the tubular members are separated from each other; a first engaging member provided on an outer peripheral surface of the first tubular member; and a second engaging member which is fixed to the second tubular member and engaged with the first engaging member. The first engaging member and the second engaging member are engaged in a state where the first tubular member and the second tubular member are pressed by the pressing member in the direction in which the tubular members are separated from each other.SELECTED DRAWING: Figure 4 【課題】第１管状部材と第２管状部材が連結されたときに第１管状部材と第２管状部材が変形することを抑制できる技術を提供する。【解決手段】管状部材の連結構造は、第１管状部材と、前記第１管状部材と並んで配置されている第２管状部材であって、その軸方向が前記第１管状部材の軸方向と一致するように配置されている前記第２管状部材と、前記第１管状部材と前記第２管状部材の間に配置されている押圧部材であって、前記第１管状部材と前記第２管状部材を互いに離間する方向に押圧する押圧部材と、前記第１管状部材の外周面に設けられている第１係合部材と、前記第２管状部材に固定されていると共に前記第１係合部材と係合する第２係合部材と、を備えており、前記第１管状部材と前記第２管状部材が前記押圧部材によって互いに離間する方向に押圧されている状態で前記第１係合部材と前記第２係合部材が係合する。【選択図】図４
