PURPOSE: A reducing apparatus of friction for a rotary compressor is provided to reduce noises by directly spraying oil to a thrust part and reducing the friction of a thrust part and to improve efficiency. CONSTITUTION: As a rotary shaft(50) rotates, friction is generated in a first and a second contact face(A1,A2) where an eccentric shaft(61) or an auxiliary bearing is contacted with a lower eccentric shaft(62). Oil is supplied to any one among the first contact face or the second contact face or both contact faces order to prevent the friction. Herein, a main bearing is contacted with an upper eccentric shaft in the first contact face while an auxiliary bearing is contacted with a lower eccentric shaft(62). Accordingly, noises are greatly decreased, and efficiency is improved.
