摘要： A drawer having metal side walls comprises a bottom plate, which is supported on angled carrying flanges of the side walls. Each carrying flange has lanced retaining lugs, which are intended to extend into a groove of the bottom plate and after the bottom plate has been placed on the flange are adapted to be bent to assume a fixing position, in which the lugs extend into the material which constitutes one or both side faces of the groove. The retaining lugs are initially lanced to extend in the longitudinal direction of the flange and are adapted to be bent up transversely to the longitudinal direction of the flange and groove. Each lug has a root portion, which merges into the flange and is not wider than the groove. At a distance from the root portion the lugs are provided with lateral projections, which during the bending up of the lugs are in pressure contact with at least one side face of the groove and dig arcuate furrows into the side face.
