| 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. |
