8 pages, 3 figures. Changes with respect to the first version: main results are unchanged, although some part of the interpretation is altered; "discussion" section is rewritten, new references and discussion of the Kramers degeneracy for transmission eignevalues are added

The effect of Rashba spin-orbital interaction upon supercurrent in S-2DEG-S proximity junctions is investigated in the clean limit. Generalization of Beenakker's formula for Andreev levels to the case of spin-orbital scattering is presented. Spin-orbit - induced splitting of Andreev bound-states is predicted for a junction of infinite width, and with non-vanishing normal backscattering at S/N interfaces. Semiclassical average of the Josephson current is however insensitive to the Rashba coupling as long as electron-electron interaction in 2DEG is neglected.
