<p>PROBLEM TO BE SOLVED: To provide a compressor that can prevent contact pressures of bearing parts from locally increasing due to deflections of a driving shaft.SOLUTION: A compressor comprises: an electric motor (50); a driving shaft (60) rotated by an electric motor (50); a compression mechanism (20) connected to the driving shaft (60); and bearing parts (28, 44, and 58) in sliding contact with outer peripheral surfaces of the driving shaft (60). In the driving shaft (60), cavity parts (76, 86, and 96) that reduces the rigidity of the driving shaft (60) are formed at locations corresponding to the bearing parts (28, 44, and 58).</p> |
