Beschreibung
Zusammenfassung:	A compressor includes a suction hole provided in a cylinder. The suction hole includes a plurality of portions being different in diameter and disposed from an outer circumferential side toward an inner circumferential side of the cylinder. The plurality of portions are reduced more in diameter toward the inner circumferential side of the cylinder. A central axis of an outer circumferential side suction hole of the plurality of portions intersects a central axis of the cylinder. A central axis of an inner circumferential side suction hole of the plurality of portions is parallel to the central axis of an outermost circumferential side portion and decentered from the central axis in an opposite direction to a direction of a spring hole.
