PROBLEM TO BE SOLVED: To provide an idling prevention method capable of combining prevention of idling of a liner and improvement of mouth piece strength.SOLUTION: A high pressure gas tank 100 includes mouth pieces 16 on apexes of dome portions 14 at both liner axial ends of a line 10. The mouth piece 16 includes a mouth piece body 16b, a mouth piece flange 16f, and a plurality of ribs 16v. The mouth piece body 16b extends along an axis AX from the outside to the inside of the liner, the mouth piece flange 16f extends in a circumferential direction from the mouth piece body 16b, and enters a caved-in pedestal portion 14r of the dome portion 14, and a flange contract face 16fs is brought into contact with a bottom surface of the caved-in pedestal portion 14r. The rib 16v extends from an outer periphery of the liner mouth piece body region 16t positioned inside of the liner to the flange contact face 16fs of the mouth piece flange 16f, and forms a recessed portion between ribs 16vs. The liner 10 is inserted and molded to the mouth piece 16, and the caved-in pedestal portion 14r is engaged with the recessed portion between ribs 16vs.SELECTED DRAWING: Figure 5 |
