본 발명에 따른 다기통 회전식 압축기는, 인접하는 복수의 압축실(21a, 21b)과, 2장의 분할판(42)으로 분할되고, 각각의 분할판(42)의 맞춤면(43)끼리를 서로 압접 고정하며, 인접하는 압축실 사이를 구획하는 칸막이판(35)을 구비한 다기통 회전식 압축기(100)에 있어서, 적어도 1장의 분할판(42)의 맞춤면(43)은 압축 기구부(3)의 크랭크축(6)의 축 방향으로 오일 구멍(51)을 형성하는 절결부(48)를 갖고, 오일 구멍(51)은 압축 기구(3)의 실린더 블록(33a, 33b)을 크랭크축(6)의 축 방향으로 관통하는 유로(52a)에 연통하는 것이다. 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).
