PROBLEM TO BE SOLVED: To improve rigidity of a scroll type compression mechanism in which at least one part of configuring members are formed by resin.SOLUTION: In a spiral groove part 21d formed at a movable side substrate part 21a of a movable scroll 21, a spiral movable side tooth part 21b formed by carbon fiber-reinforced resin is fitted. Furthermore, by bringing a tip part of the movable side tooth part 21b into contact with a fixing side substrate part of a fixed scroll, displacement of the movable side tooth part 21b in an axial direction of a rotary shaft is regulated. Thereby, change in a deformation amount by the displacement of the resin movable side tooth part 21b in the axial direction can be suppressed, and rigidity of the scroll type compression mechanism can be improved. |
