SEALED COMPRESSOR AND REFRIGERATION DEVICE

摘要

In a sealed compressor, electrically-operated element (104) and compressive element (106) driven by electrically-operated element (104) are housed in the inside of sealed container (102). Compressive element (106) includes shaft (126) formed of main shaft (136) and eccentric shaft (134), and cylinder block (128) having; bearing (144) which pivotally supports main shaft (136) of shaft (126); and cylinder (142). Further, the compressive element (106) includes piston (130) which is movable in the cylinder (142) in a reciprocating manner, and connecting portion (132) which connects eccentric shaft (134) and piston (130) to each other. Electrically-operated element (104) is formed of an outer-rotor-type motor which includes stator (150), and rotor (152) which is disposed coaxially with stator (150) so as to surround an outer periphery of stator (150). Further, non-sliding portion (146) is provided between main shaft (136) and bearing (144), and stator (150) is fixed to outer peripheral portion (162) of bearing (144) which corresponds to non-sliding portion (146).
