Single-particle spin-orbit splittings (Δ^<SO>) in ^<16>O and ^<40>Ca nuclei are evaluated within the framework of the effective interaction theory by employing the Reid soft-core potential and meson-exchange three-body forces (TBF). Among the two-body force contributions, the Pauli-rearrangement effect on Δ^<SO> is studied with special care. The TBF contribution to Δ^<SO> is found to be significant. The G-matrix, the second-order pauli-rearrangement and the TBF contribute to Δ^<SO> by the amount of 〜1/2, 〜1/5 and 〜1/4 of Δ^<SO>_<exp>, respectively. The energy-dependence of the mass operator gives about 20% reduction of Δ^<SO>, finally leaving 30% shortage to Δ^<SO>_<exp>. Further possible origins to increase Δ^<SO> are suggested.
