To provide a technology that can facilitate the manufacturing of a moving body tubular frame formed by connecting a plurality of tubular members.SOLUTION: A moving body tubular frame includes: a first tubular portion; and a second tubular potion connected to the first tubular portion via a connection portion. The connection portion includes: a first connection portion which is formed in a tubular shape, has a first slit, and has a first opening of the first slit placed in a side face so as to intersect with the axial direction of the first connection portion; and a second connection portion which is formed in a tubular shape with a substantially consistent lateral cross-sectional shape with that of the first connection portion, has a second slit, and has the second slit placed in a side face in such a way that a second opening of the second slit intersects with the axial direction of the second connection portion. The first tubular portion and the second tubular portion are connected to each other by having the first connection portion and the second connection portion engaged with each other via the first slit and the second slit.SELECTED DRAWING: Figure 5

    【課題】複数の管状部材が接続されて構成される移動体用の管状フレームにおいて、製造の容易化を実現可能な技術を提供する。【解決手段】第1管部と、接続部を介して第1管部に接続された第2管部と、を備える移動体用管状フレームであって、接続部は、管状に形成され、第1スリットを有する第1接続部であって、第1スリットの第1開口部が第1接続部の軸線方向と交差するように側面に配置される第1接続部と、第1接続部と横断面形状が略同一の管状に形成され、第2スリットを有する第2接続部であって、第2スリットの第2開口部が第2接続部の軸線方向と交差するように側面に配置される第2スリットを有する第2接続部と、を備え、第1管部と第2管部とは、第1接続部と第2接続部とが、第1スリットおよび第2スリットを介して係合することにより接続されている。【選択図】図5
