To reduce transmission sound in a suction muffler so as to improve the silencing effect of the muffler, by forming the suction muffler fixed to a compression element of refrigerant-resistant and oil-resistant vibration-damping iron plate, in a hermetic compressor provided with an electrically driven element and a compressive element elastically supported in a sealed container.

An electrically driving element 2 is started and a crank shaft 6 rotates, a piston 9 makes its reciprocating motion in a cylinder 8 via its eccentric part 11 and connecting rod 10, thereby refrigerant gas enters the cylinder 8 from a suction muffler 20 so as to be sucked compressed and discharged. In such a hermetic compressor, a suction muffler 20 for forming a silencer fixed to a compression element is formed of refrigerant-resistant and oil-resistant vibration-damping iron plate. Thereby, the vibration of the pulsative sound of refrigerant gas from a cylinder 8 generated during suction stoke is absorbed in the vibration-damping iron plate so as to exhibit its silencer effect. In addition, the suction muffler 20 is formed of synthetic resin or the like and may be covered by a muffler cover formed in compliance with the outer peripheral configuration of the suction muffler 20.
