PROBLEM TO BE SOLVED: To provide a rotary compressor capable of reducing abnormal noise generated when a thrust end surface of an eccentric part in a crankshaft collides with end surfaces of an upper and lower bearings, while securing bearing reliability of the upper and lower bearings.SOLUTION: A rotary compressor 1 includes: an upper bearing 12 and lower bearing 13 for supporting a crankshaft 7; and rotors 15, 16 fitted to eccentric parts 7A, 7B of the crankshaft 7 and turning in cylinder chambers 8, 9. Annular openings formed of annular grooves 23, 24 surrounding a bearing part are formed in the end surfaces of the upper bearing 12 and lower bearing 13. Thrust plates 25, 26 are provided between the thrust end surfaces 7C, 7D of the eccentric parts 7A, 7B in the crankshaft 7 and either or both of end surfaces of the upper bearing 12 and/or lower bearing 13. |
