Abstract
A common rail is provided which is simple in structure and capable of connecting a piping component to a thick wall pipe thereof in a highly sealed and light weighted manner. In a common rail adapted to connect a pipe component to at least one end of a thick wall pipe having a flow passage 1' therein for accumulating pressure of high pressure fuel so that high pressure fuel is supplied from a high-pressure pump and distribute-supplied to an injection nozzle, the end portion of the thick wall pipe 1 is reduced in diameter by drawing. A thread portion 1a is formed in an outer peripheral surface of the diameter-reduced end portion. A connecting end of the piping component 3 is connected to an end portion of the thick wall pipe 1 by screwing a fastening screw means 5, 5' to the thread portion 1a.
