<p>PROBLEM TO BE SOLVED: To provide a connection structure of a pipe capable of fastening the pipe penetrating through a pore opened on a partition which separates a heat exchange region from a cooling water region to reliably perform the seal, and capable of easily detaching the pipe.SOLUTION: A connection part 10 of a pipe allows a pipe 12 to be inserted to a through-hole 11a disposed on a partition 11 which separates a heat exchange region from a cooling region and is fastened by a flange 13. An edge part of the pipe 12 is inserted to a flange stepped pore part 13b, whereby the fastened position of the pipe is regulated, the pipe is fastened via a seal member 15 mounted on a ring-shaped space having a triangle cross-section constituted with three components of an outer circumferential part of the pipe 12, a seal surface part 13c of the flange 13 and the partition 11, and the seal is reliably performed by clamping force of hexagon head bolts 16.</p> |
