Abstract

This multi cylinder rotary compressor (100) is provided with: a plurality of compression chambers (21a 21b) that are adjacent to each other; and a partition plate (35) divided into two division plates (42) the meeting surfaces (43) of the division plates (42) being pressed and secured against each other for partitioning mutually adjacent compression chambers. The meeting surface (43) of at least one of the division plates (42) has in the axial direction of the crank shaft (6) of a compression mechanism part (3) a cutout (48) forming an oil hole (51). The oil hole (51) communicates with an oil path (52a) penetrating cylinder blocks (33a 33b) of the compression mechanism (3) in the axial direction of the crank shaft (6).
