Abstract

The inner space of a casing (31) is partitioned by partition members (61, 80) into a first space (38) and a second space (39). In the first space (38) is placed an expansion mechanism (60), and in the second space (39) are placed a compression mechanism (50) and an electric motor (45). A terminal (90) is provided on the casing (31) such that the rear surface side of the terminal faces the second space (39).
