PROBLEM TO BE SOLVED: To provide a technology capable of determining a position and a direction of one whole cylindrical component with a simple constitution in work to connect a plurality of cylindrical components.SOLUTION: A connection structure 18 of cylindrical components comprises a first cylindrical component 12 having an opening part 44 formed in an outer peripheral part and a second cylindrical component 14 connected having a base end part made to abut on the opening part 44. A first fitting part 46 is formed at the opening part 44 of the first cylindrical component 12, and a second fitting part 48 is formed at the base end part of the second cylindrical component 14, which is positioned against the first cylindrical component 12 in a radial direction Pa and a peripheral direction Pb of the second cylindrical component 14 as the first fitting part 46 and a second fitting part 46 are fitted to each other.SELECTED DRAWING: Figure 6 |
