Abstract (en)
[origin: EP3738470A1] The present disclosure relates to a sliding device for a drawer capable of reinforcing rigidity while reducing noise during operation by mixing and using a plurality of slide balls having different tensile strengths, and includes: a fixed rail fastened and fixed to a main body, a movable rail fastened and fixed to a storage body, and sliding on the fixed rail, an intermediate rail disposed between the fixed rail and the movable rail to guide the sliding movement of the movable rail, and ball assemblies disposed between the intermediate rail and the fixed rail and between the intermediate rail and the movable rail, respectively to move to be slidable, and provided with a plurality of slide balls having different tensile strengths, the slide ball having a large tensile strength being disposed at the outermost side thereof. According to such a configuration, it is possible to reduce the noise using the slide ball having the low tensile strength as a whole, and to reinforce rigidity using the slide ball having the large tensile strength in a portion to which a shock load is applied.
