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 1):
A high pressure tank comprising:\n a resin liner configured to contain a fluid; and a cap including a supply/discharge hole formed in the cap and configured to supply and discharge the fluid to and from the liner, wherein: a cylindrical portion is formed with the liner in a protruding manner, in a state where the cylindrical portion is inserted in the supply/discharge hole, a direction from a distal end to a proximal end of the cylindrical portion is a supply direction of the fluid for the liner; a seal groove is formed in an inner circumferential surface of the supply/discharge hole, a seal member configured to seal a gap between the inner circumferential surface of the supply/discharge hole and an outer circumferential surface of the cylindrical portion and a back-up member disposed on an upstream side of the seal member in the supply direction are provided in the seal groove; the seal groove has a tapered groove surface facing toward the back-up member, the tapered groove surface being apart from the outer circumferential surface of the cylindrical portion from an upstream side to a downstream side in the supply direction; and the back-up member has a tapered member surface facing toward the tapered groove surface, the tapered groove surface having a diameter expanding from the upstream side to the downstream side in the supply direction.
