ABSTRACT:
In a rotating compressor, an outer peripheral surface of a partition member which is secured firmly to a casing so as to divide the inside of the casing into a high-level pressure space and a low-level pressure space, is provided with a peripheral groove for allowing for shrinkage of the casing at a weld area where a trunk part and end plate of the casing are welded together. As a result of such arrangement, the partition member is strongly tightened by making utilization of such shrinkage, thereby not only enhancing sealability between the high-level pressure space and the low-level pressure space in the inside of the casing but also preventing a drop in workability during assembling and an increase in cost.
