ABSTRACT:
A rotary compressor has a main bearing and a sub-bearing which are disposed on both sides of a cylinder, and a vane which is inserted at an eccentric crank pin portion of a crankshaft and is adapted to reciprocate while being in contact at one end thereof with a roller eccentrically rotating inside the cylinder. An oil feeding mechanism for the rotary compressor comprises: an oil feeding hole provided in a portion of the crankshaft closer to the end surface of a sub-journal of the crankshaft; an oil hole provided in a crank pin portion of the crankshaft such as to communicate with both the oil feeding hole and an oil groove formed on the crank pin portion; a spiral oil groove formed in the outer periphery of a main journal of the crankshaft such as to spiral in the direction opposite to the rotational direction of the crankshaft; and a spiral oil groove formed in the outer periphery of the sub-journal of the crankshaft such as to spiral in the same direction as the rotational direction of the crankshaft.
