A cryogenic vessel for a superconducting apparatus has an inner vessel which houses a freezing mixture and a winding of a superconducting apparatus. The inner vessel is surrounded by a vacuum insulating vessel which thermally insulates the inner vessel. A connecting pipe connects the inside of the inner vessel with the outside of the vacuum insulating vessel. A cylindrical dividing pipe which surrounds the connecting pipe with a radial clearance therebetween extends into the inner vessel and is connected between the inner end of the connecting pipe and the inner vessel. A gas flow passageway is formed between the inner end and the outer end of the connecting pipe, the passageway bordering on the inner or outer surface of the connecting pipe. During normal operation, gas which is formed by the vaporization of a freezing mixture contained inside the inner vessel continually passes along the passageway, absorbing heat from the connecting pipe and reducing the amount of heat which penetrates into the inner vessel by conduction along the connecting pipe. A wiring support pipe for the power supply leads of a cryogenic vessel according to the present invention is a single, rigid pipe which has one of its ends connected to an inner vessel or a vacuum insulating vessel by a flexible tube which absorbs thermal shrinkage.
