Abstract
Abstract The invention relates to a float for a level indicator of a fluid reservoir. The float comprises an annular body made of two cup-like synthetic plastics members welded together. The body comprises an inner cavity consisting in two blind holes separated by a radial wall and having their blind ends of equal diameter. The upper hole is stepped to receive an annular plug traversed by a float rod engaged in a central bore provided in the radial wall. The inner wall of the body is provided with radial projections located in the second blind hole.
