Tank attachment mechanism and a vehicle equipped with a tank

摘要

A tank attachment mechanism (100) configured to mount a long cylindrical tank (T) to a vehicle, the tank attachment mechanism (100) comprising: a tank contact seat disposed on a vehicle body so as to engage with a cylindrical side surface of the tank (T); T) comes in contact at a plurality of different positions on an outer circumference of the transversely disposed tank (T); wherein the tank contact seat has a pair of inclined surfaces (112R, 112F) which contact the cylindrical side surface of the tank (T) at a plurality of different positions on the outer circumference of the transversely disposed tank (T); a tank band (140) configured to clamp the tank (T) in contact with the tank contact seat against the tank contact seat; a tank end surface contact structure (121) configured to contact an end surface of a tank edge member (TVB) disposed on at least one edge surface of the tank (T); and a rotation positioning member (122) disposed on the tank end surface contact structure (121) so as to be aligned with a tank rotation positioning specific mark (TVS) formed on the end surface of the tank edge member (TVB) Determines the rotational position of the tank (T) in contact with the tank contact seat.
