PROBLEM TO BE SOLVED: To prevent the occurrence of noise and vibration with a relative movement of an eccentric part 62 of a driving shaft 31 in a clearance inside of the cylinder 21 in the axial direction in relation to the cylinder 21 by pressure pulsation before and after a discharge of the coolant gas compressed in a compression chamber 26 into the casing 10 in a rotary sealed compressor 1 provided with a compression mechanism 20 for compressing the coolant gas and a driving motor 30 for driving the compression mechanism 20 through the driving shaft 31 in the casing 10. SOLUTION: This sealed compressor is provided with a slide-contact plate 81 interposed between the inner surface of the cylinder 21 in the periphery of a shaft hole 23a of a front head 23 and a surface of the eccentric part 62 facing the inner surface of the cylinder 21, and a compression spring 82 installed in the shrinking condition between the slide-contact plate 81 and the inner surface of the cylinder 21 of the front head 23 to push the eccentric part 62 toward a rear head 24 so that the eccentric part 62 is pushed to the inner surface of the cylinder 21 of the rear head 24.
