Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a scroll compressor which can suppress occurrence of a crack or the like, in a caulking part of a bearing and a housing to improve reliability.SOLUTION: Since a low rigid part 70A of an annular groove is formed near the caulking part 60, when a compressor 10A is operated and gas repeats compression inside a compression chamber 50 formed between a fixed scroll 30 and a revolution scroll 20, a load acts on the revolution scroll 20 in a direction along an axis of a main shaft 12 so that part of stress occurring in the housing 11 acts on the low rigid part 70A. This reduces the stress acting on the caulking part 60.
