Abstract

In a pipe joint structure, a second screw thread formed on an outer circumference end of a joint member is screwed deep into a first screw thread formed on an inner circumference of a cylindrical joint fitting member whose axial end is bonded to a common rail body so that a second flat surface at an axial end of the joint member is pressed against a first flat surface on an outer circumference of the common rail body to form a fluid tight sealing surface therebetween in a state that a fluid passage opened to the second flat surface communicates with a through-hole opened to the first flat surface. Accordingly, even if a position of the joint fitting member to the common rail body is slightly shifted, fluid tight sealing between the first and second flat surfaces is assured.
