ABSTRACT:
In a reservoir unit installed in a fuel tank, in order to reduce noise generated from the engaging faces between guide rails extending from a plate-shaped portion of an upper subunit, fixed to the top face of the fuel tank, to a lower subunit, and slots provided in a reservoir in the lower subunit, a reservoir is configured of an upper subunit, a lower subunit and an elastic member, wherein the upper subunit is provided with a plate-shaped portion to block an opening formed in the fuel tank and guide rails extending from that plate-shaped portion to the bottom of the fuel tank; and slots and to slidably accept those guide rails are integrally formed with a reservoir. A metal plate intervenes between at least one position of the engaging face of the inner circumference of each slot and a guide rail, and the guide rails are formed in a flat plate shape, with slits extending upward from the lower part being formed at the tip of each.
