Claim 2:
3. The high-pressure gas tank connection structure of claim 2, further comprising:
a fixed member formed in a tubular shape and mounted to the other axial direction end portion side of the tank main body, and at which the thermally-actuated pressure relief device is mounted to another concave portion that is formed along the axial direction of the tank main body so as to be concave toward the inner side of the tank main body;
a communication path that, at the other concave portion, passes through along a direction orthogonal to an axial direction of the fixed member from an inner surface of the other concave portion over to an outer surface of the fixed member, and, in a case in which the high-pressure gas is released, the communication path communicates the interior of the tank main body with the exterior to the tank main body by a safety valve that is provided at the thermally-actuated pressure relief device;
a ring provided at the outer surface of the fixed member, a gap being formed between the ring and the outer surface of the fixed member and being able to communicate with the communication path, and the ring being able to move along a peripheral direction with respect to the fixed member and being unable to move along an axial direction with respect to the fixed member; and
a jetting port formed at the ring and passing through from an inner surface over to an outer surface of the ring, and being able to communicate the communication path with the exterior to the tank main body through the gap.
