PROBLEM TO BE SOLVED: To efficiently suppress generation of noise.SOLUTION: A rotor 37 constituting a motor 36 of a compressor 10 is cylindrical. A shaft 23 is inserted through a hole 51 formed at a central part of the rotor. A guide groove 50 is formed in the shaft 23 continuously in an axial direction thereof. A guide projection 52 is formed on an inner circumferential surface of the hole 51 continuously along the axial direction of the shaft 23. The guide projection 52 can relatively slide and move in a direction in which the guide groove 50 continues, while being inserted into the guide groove 50. Accordingly, the rotor 37 can slide and move along the axial direction of the shaft 23. |
