Abstract: An on-board gaseous fuel tank module includes: a support frame member; and a gaseous fuel tank fixed to the support frame member horizontally. The gaseous fuel tank includes: a cylindrical tank complete unit, a gaseous fuel inlet and outlet valve device provided at an axial end portion of the tank complete unit such that a part thereof protrudes outwardly from the tank complete unit, and a pin hole provided in the other axial end portion of the tank complete unit so as to open outwardly. An axis of the tank complete unit, an axis of the part of the valve device and a center line of the pin hole are disposed on a single straight line so that the part of the valve device and the pin hole are used to position the gaseous fuel tank horizontally.

Abstract: A fuel tank structure has a plurality of cylindrical tank main bodies (4), a piping (36) arranged to communicate the end portions of the tank main bodies 4 from one another and a block-shaped connector portion (35) provided at the outside of the end portion of the tank main body (4). The piping (36) couples the corresponding connector portions (35) to each other and is entirely disposed to the tank main body side with respect to an end surface of the connector portion (35), which is on the opposite side to the tank main body (4) with respect to the connector portion.
