PROBLEM TO BE SOLVED: To favorably prevent a second bearing 11 from being seized since lubricating oil O can be directly supplied to a sliding portion of the second bearing 11.SOLUTION: A through-hole 7D is formed at a base 7A of a turning scroll 7 in such a manner as to extend from the inside of a cylindrical portion 7C thereof to a rear end face of the base 7A. A through-hole 6C is formed at the lowermost portion of a fixed scroll 6. When two through-holes 6C, 7D are overlapped with each other by the turning of the turning scroll 7, lubricating oil O reserved at the inside bottom of a discharge chamber 13 is supplied to a second bearing 11 through the through-holes 6C, 7D by the pressure of a refrigerant gas G in the discharge chamber 13. |
