The stator (129) of an outer rotor-type motor is affixed to a stator affixation member (130), and the stator affixation member (130) is affixed to a member (cylinder block (111)) provided with the primary bearing (119) of a compression element. Further, a secondary bearing (133) is configured as a separate element from the stator affixation member (130) and is affixed to the stator affixation member (130). Consequently, the stator affixation member (130) can be affixed to a compression element member while the gap between the inner periphery (128a) of a rotor (128) and the outer periphery (129a) of the stator (129) is maintained uniform, and the secondary bearing (133) can be affixed to the stator affixation member (130) while the secondary bearing (133) is ensured to be coaxial with the primary bearing (119). Thus, the gap between the inner periphery (128a) of the rotor (128) and the outer periphery (129a) of the stator (129) can be reduced, and motor efficiency can be increased. |
