Abstract

Abstract In an external casing (5) arranged vertical to fuel surface in a fuel tank of vehicles or the like are provided a slender resistance body (6) along the axial line of the external casing (5), a contact member (7) in sliding contact with the resistance body (6) and a support block (16) orfloat (22) for arranging the contact member (7) in the most suitable contact with the resistance body (6). The shape of contact point of the contact member (7) is arranged in such form as is capable of lessening the resistance of its contact with the resistance body (6) to an extent as feasible as possible. In order to avoid bad influence on the action of the resistance body (6) and contact member (7), there is formed a recess portion at the bottom of the external casing (5) for the fuel gauge.
