Common rail, common rail holder, and method of producing common rail

摘要

The present invention provides a common rail formed by bonding a common rail body and a common rail holder which has a pressing surface and a convex bonding surface, by means of a heat pressure bonding process and a liquid phase diffusion bonding process, wherein the height H of the convex bonding surface satisfies 1 μm≦H≦50 μm, and the common rail holder includes a deformation introducing portion in which an area of a cross-section parallel to the pressing surface is smaller than the area of the pressing surface.
