A hermetic reciprocating compressor has a rigidity increasing portion for increasing the rigidity of a sealed casing of the compressor to control transmission noise that is transmitted through the sealed casing and to reduce the noise of the compressor. The rigidity increasing portion includes an elastic member which exerts elasticity between a compression device portion and a lower shell of the compressor. The elastic member increases the rigidity of the lower shell of the compressor to produce noise controlling effects similar to that which results from an increase in the thickness of the shell of the compressor itself Accordingly, noise and vibration levels are improved by the sealed casing, and the noise of the compressor can be reduced. The elastic member includes a body having an annular hole in contact with the center of the bottom of the lower shell and a plurality of supporting legs extending from the body. The lower shell of the compressor has a plurality of snubbers arranged thereon, and each supporting leg of the elastic member is connected to a respective snubber. As a result, the transmission path of the vibration, from the electronic device portion and the compression device portion to the sealed casing, is dispersed, with some of the vibration being absorbed by the sealed casing itself. Accordingly, vibration of the compressor is reduced.
