<p><P>PROBLEM TO BE SOLVED: To provide a fluid supply valve attachment device can suppress deformation or fatigue of a fixing member 1 and a first seal member, and contribute to elongation of service lives of the fixing member 1 and first seal member. <P>SOLUTION: In the fluid supply valve attachment device, a tank 3 includes a first inner peripheral wall face 33 forming a mounting hole 32. The fixing member 1 is suitable for the mounting hole 32, and is provided with a first outer peripheral wall face 105 opposing to the first inner peripheral wall face 33, a recessed fitting part 17 opened on a fluid tank chamber 30 and a second inner peripheral wall face 19 forming the recessed fitting part 17. A fluid supply valve 4 is inserted to the recessed fitting part 17, and is provided with a second outer peripheral wall face 403 facing the second inner peripheral wall face 19. The first seal member 14 seals a space between the first inner peripheral wall face 33 and the first outer peripheral wall face 105. A second seal member 65 seals a space between the second inner peripheral wall face 19 and the second outer peripheral wall face 403. When the maximum inside diameter of the recessed fitting part 17 is defined as D [mm] and a distance between the center of the first seal member 14 and the center of the second seal member 65 in an extending direction in which the axial line of the recessed fitting part 17 is extended as L1 [mm], L1 is set within 2.5D. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
