A conveying pipe can improve operationality of manufacturing operation of a conveyin pipe and position a fuel injection valve to a desired position in a rotary direction of a central axis. A protrusion (16) of a tubular connector (10) is provided with an arc (16A) externally connected to the tubular connector (10) and a pair of sloping edges (16B, 16C) which linearly extend from end points (21, 22) of the arc (16A) to a mutually intersected direction. The protrusion (16) is configured to pass through a central shaft (23) of the tubular connector (10) and takes a straight line extending in a direction orthogonal to a cylinder column direction as a reference line (24), and, taking the reference line (24) as a reference, the arc (16A) is asymmetric relative to the reference line (24). The sloping edges (16B, 16C) are configured at a region which passes through the end points (21, 22) of the arc (16A) and is between two imaginary lines (26, 27) parallel to the reference line (24).
