Claims (2)

[Scope of utility model registration request] (1) A crankshaft driven by an electric element, a piston rotatably fitted to the eccentric part of the crankshaft, the tip of which touches the outer periphery of the piston and makes reciprocating motion, making the inside of the cylinder a refrigerant suction chamber. A rotary type with a vane divided into compression chambers, a main bearing and an end bearing that support the crankshaft, and grooves concentric with the bearing on both sides of the bearing seat to give flexibility to both bearings. A rotary compressor, characterized in that a partition plate is provided between the cylinder and the upper bearing, the partition plate having a hole through which the end shaft of the crankshaft sufficiently passes. (2) The rotary compressor according to claim 1, wherein the flexible portion of the end bearing is lower than the seat surface to form a step. ′
