A muffler outlet is provided in each flared portion. A second outlet and a refrigerant path hole of an upper end plate are positioned on an inside of one of a plurality of flared portions, and an opening area of the muffler outlet of one flared portion is greater than an opening area of the muffler outlet of each of the other flared portions.
