Zusammenfassung:	PROBLEM TO BE SOLVED: To immediately ensure sealing of a clearance between a movable member and a fixed member when starting a compressor, in a freezer including the compressor having a two-stage compression type compression mechanism. SOLUTION: On the back surface side of the movable end plate (71a) of a high-stage compression section (70), a high-stage press member (45) applied with pressure of a high-pressure refrigerant delivered from the high-stage compression section (70) is provided for pressing the movable end plate (71a) toward the fixed member (72), and an auxiliary press portion (46) applied with pressure of the refrigerant during compression in the high-stage compression section (70) is provided for pressing the movable end plate (71a) toward the fixed member (72).
