PROBLEM TO BE SOLVED: To provide an accumulator container of high reliability easy to be washed. SOLUTION: A body 20 of a common rail 10 is formed with an accumulator chamber hole 40 for communicating one end 20a and the other end 20b of the body with each other. A seal plug 30 sealing the one end 20a of the accumulator chamber hole 40 is inserted into the accumulator chamber hole 40 from the other end 20b of the body 20, and pressed into a reduced-diameter part 43 of the accumulator chamber hole 40. A seal part 31 of the seal plug 30 abuts on an abutment part 44 of the accumulator chamber hole 40. When high-pressure fuel is stored in an accumulator chamber 11, the seal plug 30 is energized in the abutment part 44 direction by the pressure of fuel inside the accumulator chamber 11. As a result, the seal part 31 and the abutment part 44 are adhered to each other by a large force to prevent the leak of the fuel and to improve reliability. Since both ends of the accumulator chamber hole 40 are communicated with each other, the inside of the body 20 can be easily washed. |
