PROBLEM TO BE SOLVED: To suppress the lowering of performance by suppressing the wear of the sliding parts of the compression mechanism part of a scroll compressor. SOLUTION: In the rear cylindrical part 12b of a rotary scroll 12 in which an eccentric bearing 43 is contained with a very small gap, an oil groove 13 is formed in the inner surface of the cylindrical part 12b and the bottom surface 12d of the cylindrical part at the rear of a rotary scroll end plate. Since a part of the lubricating oil 7 fed into a liquid sump 21 is supplied to the inner surface of the cylindrical part 12b through the oil grooves 13, the wear of the sliding parts of the eccentric bearing 43 with an outer ring 43b can be suppressed.
