Abstract: 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.

Abstract: Provided is a spacer configured such that a protruding portion remaining after removal of a portion unnecessary after molding does not contact an inner wall of a coolant water flow path and therefore, even a portion of the spacer in the vicinity of the remaining portion can be positioned close to the cylinder bore side inner wall. The spacer of this embodiment is a spacer (4) formed of a resin molded body and inserted, in use, into a coolant water flow path (3) through an opening (30) of the coolant water flow path (3) that is formed around a plurality of cylinder bores (2) formed adjacent to each other in a cylinder block (1) of an internal combustion engine. The spacer (4) includes a spacer body (40) formed in a cylindrical shape to surround the cylinder bores (2), and a protruding remaining portion (5) remaining after removal of a portion (6ba) necessary in molding and unnecessary after molding. The remaining portion (5) is formed at an end surface (44a) positioned on a side close to the opening (30) of the spacer body (40).

Abstract translation: 提供了一种间隔件，其构造成使得在取出成型后不需要的部分之后剩余的突出部分不接触冷却剂水流路的内壁，因此，甚至在其余部分附近的间隔件的一部分可以被定位 靠近气缸孔侧内壁。 本实施方式的间隔件是由树脂成形体形成的间隔物（4），并且在使用中通过形成的冷却水流路（3）的开口（30）插入冷却水流路（3） 围绕在内燃机的气缸体（1）中彼此相邻形成的多个气缸孔（2）。 间隔件（4）包括形成圆柱形以围绕气缸孔（2）的间隔体（40），以及在取出模制所必需的部分（6ba）之后剩余的突出的剩余部分（5） 。 剩余部分（5）形成在位于靠近隔离体（40）的开口（30）的一侧的端表面（44a）处。
