Reservoir unit

Abstract

In order to fit a reservoir unit to be installed in a fuel tank in such a manner that the air-tightness of the fuel tank be not lost even if a large acceleration or deceleration works on the fuel tank, the reservoir unit is configured of an upper subunit, a lower subunit and an elastic member. The upper subunit is provided with a plate-shaped portion to block an opening formed in the fuel tank and guide rails and extending from that plate-shaped portion to the bottom of the fuel tank, and the two elements are integrally molded of resin. The lower subunit is provided with a resin-built reservoir, and slots to slidably accept the guide rails are integrally molded with the reservoir. When a large force works on the reservoir unit and the fuel tank, the guide rails and are destroyed before the plate-shaped portion would be, so that the destruction of the plate-shaped portion can be prevented.
