Abstract:
A high pressure tank includes: a resin liner for containing a fluid; and a cap including a supply/discharge hole. A cylindrical portion formed with the liner in a protruding manner is inserted in the supply/discharge hole. In a seal groove formed in an inner circumferential surface of the supply/discharge hole, a seal member and a back-up member disposed on an upstream side of the seal member in the supply direction are provided. A tapered groove surface of the seal groove facing toward the back-up member is apart from the outer circumferential surface of the cylindrical portion along the supply direction. A tapered member surface of the back-up member facing toward the tapered groove surface has a diameter expanding along the supply direction.

Claim (Index 3):
The high pressure tank according to  claim 2 , wherein:\n an inclination angle of the tapered member surface with respect to an axial direction of the back-up member is larger than an inclination angle of the tapered groove surface with respect to the axial direction of the supply/discharge hole; and in a state where the tapered member surface is aligned with the tapered groove surface, a distance between a first line and a second line is equal to or greater than half of a distance between the first line and a third line, the first line extending along the axial direction of the supply/discharge hole and passing through one end of the tapered member surface on the downstream side in the supply direction, the second line extending along the axial direction of the supply/discharge hole and passing through another end of the tapered member surface on the upstream side in the supply direction, the third line extending along the axial direction of the supply/discharge hole and passing through an end portion of the back-up member on the downstream side in the supply direction, facing toward the outer circumferential surface of the cylindrical portion.
