Abstract

To provide an oil tank of turbo compressor for refrigerator and turbo compressor for refrigerator in which a heater can be replaced or inspected without recovering oil present within an oil tank and refrigerant present in the turbo refrigerator. The present invention relates to an oil tank 10 of a turbo compressor 3A for a refrigerator forming a bottom part of a casing 14 comprising: a bottom plate 11; and side plates 12, 13 vertically arranged vertically from an outer peripheral edge of the bottom plate 11 and constituting the turbo compressor 3A for a refrigerator. The side plate 12 is formed with a through-hole 21 passing in a plate thickness direction, a protection pipe 22 having an extremity end as a closed end is inserted into and passed through the through-hole 21 and at the same time a rod-like heater 26 constituted in such a way that it can be pulled out or inserted into the protection pipe 22.
