The upper end of the drive shaft is configured as an eccentric shaft portion. The sliding bearing is provided between the boss portion and the eccentric shaft portion. An axially central portion of the boss portion is more rigid than a connection portion of the boss portion connected to the movable scroll. The boss portion is shaped so that the central portion projects outward.
