PROBLEM TO BE SOLVED: To provide a shaft penetration two-stage scroll compressor which can be downsized.SOLUTION: A two-stage scroll compressor includes an orbiting scroll (5), a first fixed scroll (3) having a spiral first groove part (34) to be engaged with a spiral first tooth part (51) of the orbiting scroll, a second fixed scroll (4) having a spiral second groove part (41) to be engaged with a spiral second tooth part (52) of the orbiting scroll, a drive shaft (2) which is rotatably supported by the first and second fixed scrolls, and pivotably supports the orbiting scroll by an eccentric crank part (21), and a rotation preventive mechanism (6) for preventing the rotation of the orbiting scroll. The rotation preventive mechanism includes a plurality of pins (61) supported at both ends by the first and second fixed scrolls, and a plurality of through holes (62) formed in the orbiting scroll with the plurality of pins being penetrated therethrough. The plurality of pins are arranged on the inner circumferential side from each groove part of the each fixed scroll. |
