いう問題点がある。(Prior Art) Conventionally, a so-called hermetic compressor is known as this type of scroll compressor. In the case of a hermetic compressor, a compression mechanism including a fixed scroll member and a movable scroll member, and a drive unit including a motor and giving orbital motion to the movable scroll member are disposed in the compressor housing, and the compressor The housing is sealed by welding or the like to completely prevent refrigerant gas from leaking out of the housing (for example, in
(Publication No. 291793) (Problems to be Solved by the Invention) Incidentally, in the case of a hermetic scroll type compressor, while there is an advantage that refrigerant gas does not leak out of the compressor housing, it is difficult to completely close the compressor housing. Since the compressor must be sealed tightly, there is a problem in that the assembly of the compressor is extremely troublesome. Furthermore, after the compressor is assembled, the compressor is tested (particularly the compression mechanism test), so if the test results are negative, it is extremely difficult to disassemble and inspect the inside and replace parts. The problem is that it is difficult.
