<P>PROBLEM TO BE SOLVED: To obtain a fluid storing device for reliably preventing the displacement of a sealing means, such as an in-tank valve, by the high pressure of fluid stored in the device body without increasing the size of a mouthpiece section. <P>SOLUTION: An external thread 38 is formed at the outer periphery section of the mouthpiece section 16 in a tank 10, and an internal thread 36 of a box nut 32 is screwed to the external thread 38, thus fitting the box nut 32 to the mouthpiece section 16. In the in-tank valve 22, a flange section 30 is pressed to a flange section 40 of the box nut 32 while a valve body 24 is being inserted into the mouthpiece section 16. As a result, the area between the flange section 30 and the upper end section of the mouthpiece section 16 is sealed. Although the pressure of fluid stored in the tank body 12 operates on the box nut 32 via the in-tank valve 22, the external thread 38 becomes a pressure reception section and the displacement in the box nut 22 is regulated, thus regulating the displacement of the in-tank valve 22. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
