Scroll compressor with controlled pressing force

A scroll compressor, comprising:

• a scroll compression mechanism including an orbiting scroll, a fixed scroll, and a thrust plate, the fixed scroll facing the orbiting scroll to form a compression chamber, the compression chamber compressing refrigerant gas, and the thrust plate supporting a load of the orbiting scroll in a thrust direction;
• a back-pressure application mechanism that applies, as back pressure, the refrigerant gas compressed by the scroll compression mechanism to a rear surface of the thrust plate;
• a floating amount restriction mechanism that restricts an amount of floating of the thrust plate caused by the back pressure;
• and
• a housing that houses the scroll compression mechanism, the back-pressure application mechanism, and the floating amount restriction mechanism, wherein
• the floating amount restriction mechanism restricts the amount of floating through locking of a peripheral edge of the thrust plate to an inner circumferential wall of the housing;
• wherein
• the inner circumferential wall of the housing includes a groove that recedes from a surface of the inner circumferential wall in a thickness direction, and the peripheral edge of the thrust plate is inserted into the groove so as to be locked to the inner circumferential wall of the housing.
