PROBLEM TO BE SOLVED: To provide a scroll compressor for compatibly suppressing the leakage of fluid during low-speed operation and suppressing sliding loss during high-speed operation.SOLUTION: A scroll compressor 1 includes a crank shaft 51 having a main shaft part 51a rotatably held by bearings 17, 18 and adapted to be rotated around a rotational axis, an eccentric shaft part 51c connected to the upper end face of the main shaft part 51a and engaging with a rocking scroll 41 on an eccentric axis eccentric from the rotational axis, and a balance weight part 51d connected to the upper end face of the main shaft part 51a and having a gravity center located in opposition to the eccentric axis with reference to the rotational axis. A portion connected to the upper end face of the main shaft part 51a of the crank shaft 51 and a gravity center determined from all members to be rotated or rocked by the portion are located in opposition to the eccentric axis with reference to the rotational axis. |
