摘要： A tubular body formed by joining two semi-tubular portions that are divided in radial direction, the tubular body having a connection flange portion provided with a bolt hole on at least one end portion. The two semi-tubular portions have joint projection portions at both edge portions in circumferential direction, the joint projection portions projecting in radial direction and extending in axial direction, and each joint projection portion of the semi-tubular portions on at least one of both sides in circumferential direction is configured to be bent so as to deviate from a virtual division face passing a central axis in such a manner that a joint portion formed by abutting the joint projection portions does not interfere with a tool for fastening a bolt inserted into the bolt hole in a predetermined area in the vicinity of the bolt hole of the connection flange portion.
