PROBLEM TO BE SOLVED: To prevent a positional deviation in a diametrical direction on both of a cylinder block and a pair of side blocks due to long time operation.SOLUTION: In a compressor 1A, a compression mechanism portion 4 is disposed in a housing 2, and the compression mechanism portion 4 is equipped with a cylinder block 41, a pair of side blocks 42 and 43, and a rotor 10 disposed in a cylinder chamber 40. The compressor 1A carries out one cycle of sucking, compressing, and discharging of a coolant by the capacity change of a compression chamber 14 during a period of one rotation of the rotor 10. The cylinder block 41 is positioned in a diametrical direction by a housing 2, and the front side block 42 and the cylinder block 41 are positioned in the diametrical direction. The housing 2 is provided with an abutting surface 50 on which an end surface on the outside of the rear side block 43 abuts. By the fastening force of a through-bolt 54, the end surface of the rear side block 43 is made to abut on the abutting surface 50. |
