A hermetically enclosed rotary compressor which is less likely to fall, obtained by minimizing an increase in the installation area by configuring the rotary compressor in such a manner that the overall height (H) of the compressor body (1) measured from the bottom surfaces of support legs (2) is set to be 2.5 or more times as large as the outer diameter (D) of the compressor body (1) (H/D> =2.5), the height (Hg) of the center of gravity (G) measured from the bottom surfaces of the support legs (2) is set to be 1/2 or less of the overall height (H), Rc/cos theta < Rb < L is satisfied, and the number of the support legs is four or more, where Rb is the radius of the support points of the compressor body (1), Rc is the outer radius of the compressor body (1), L is the distance from the vertical axis (Oa) of the compressor body (1) to the vertical axis (Ob) of an accumulator (4), and theta is half the angle formed between adjacent support legs (2) about the axis (Oa).
