Influence of a spiral spin structure on the superconducting (SC) pairing in the most probable active γ band of Sr₂RuO₄ is studied in the mean field approximation. Such structure with "incommensurate" vector Q=2π(1/3,1/3) has been proposed as that which removes the nesting instability in, bands. The model pairing interaction of adjacent centres is adopted. The mixed singlet and triplet SC order is revealed. The d-wave singlet pairing is accompanied by formation of the p-wave triplet pairs with large total momentum Q and spin projections ± 1 onto axis normal to the spin rotation plane of the spiral structure. Both the superconducting and normal states have a broken time reversal symmetry which might be detected by polarised photoemission.
