Abstract
To obtain a gasoline direct injection rail in which a large load is unlikely to be concentrated on a boundary part between a rail body and an end cap, and damage to the boundary part can be prevented, even when high pressure is applied to the inside of the rail body. The gasoline direct injection rail comprises an end cap 4 composed of a top plate 5 and a circumferential wall 6, and a rail body 1 having an end part 2 in which the circumferential wall 6 of the end cap 4 is inserted and placed, wherein an inner circumference of the end part 2 of the rail body 1 has a depression 3, the circumferential wall 6 is placed in the depression 3, and there is no level difference at a boundary part 12 between an inner circumferential surface 11 of the circumferential wall 6 and an inner circumferential surface 10 of the rail body 1.
