Abstract: Provided is a pressure vessel capable of adapting a release direction of gas in the pressure vessel (i.e., release-permitted direction) and a direction in which the gas in the pressure vessel should not be released (i.e., release-restricted direction) to an attitude of a vehicle or a surrounding environment. A release direction control unit is configured to variably change, with respect to the pressure vessel, a release direction of gas as a pressure relief valve opens, and without depending on an attitude of the pressure vessel, release the gas stored in the pressure vessel as the pressure relief valve opens (only) in the release-permitted direction set in advance with respect to a gravity direction, not in the release-restricted direction set in advance with respect to the gravity direction.

Abstract: To obtain a fuel filler structure for a fuel tank wherein when causing an opening and closing valve to close, it can be ensured that the opening and closing valve does not rapidly rotate to a closed position in which it closes a fuel fill inlet, and when causing the opening and closing valve to open, the opening and closing valve can be opened with a small force. A fuel filler structure is equipped with a damper on the near side of a flapper valve in the insertion direction of a fuel nozzle. When the flapper valve rotates to an open position, the damper does not act on the flapper valve, and when the flapper valve rotates to a closed position, the damper acts on the flapper valve.
