ABSTRACT:
An inexpensive enclosed type rotary compressor capable of diminishing vibration. A balance weight is split into two parts. A first balance weight is formed by die casting, forging, sintering or the like to be in such a form that its end portions each having a hole for accommodating by a fixing protrusion are thinner than the remaining portion, and a second balance weight is formed as a single plate or laminated plates in plural layers and securedly sandwiched between the end ring of a rotator and the first balance weight. As a result, the balance weight can be standardized, realizing cost efficiency.
