To provide a bearing structure capable of being used under the circumstances of very low temperature in a narrow installation space, a gear structure free from the galling of tooth flanks to each other even in being used under the circumstances of very low temperature, and compact reduction gears having superior drive transmission efficiency under the circumstance of very low temperature.
In this bearing structure used under the circumstance of very low temperature, a shaft 1 and a sliding bearing member 2 made of austenite stainless steel including Cr, Ni and Mo are used, and baking-type solid lubricating films 11 mainly composed of MoS2 are formed on sliding faces S1, S2 of the shaft 1 and the sliding bearing member 2. In this gear structure used under the circumstances of very low temperature, a gear 2 made of austenite stainless steel including Cr, Ni and Mo is used, and an ion plating film 13 composed of CrN is formed on its tooth flank 3.
