摘要： The present invention has its main object in providing a bearing device of a motor superior in its resistance to impact and sliding performance. Therefore, according to the present invention, a shaft and a sleeve into which the shaft is inserted are formed from stainless steel, and a plating layer formed by means of an electroless nickel plating so as to have a phosphorous concentration of at least 6% and at most 12% and subjected to a precipitation hardening treatment in an atmosphere of at least 500° C. and at most 700° C. is provided on a surface of the shaft. Thereby, the sliding performance of the bearing device having a superior resistance to impact can be improved.

摘要： Disclosed are a lubricant whose oxidation degradation is inhibited, and a dynamic pressure bearing device which has a long lifespan by prolonging the period of time of depression of a lubricating function of the lubricant occurring as a result of oxidation degradation. Ester-based lubricating oil serving as the lubricant is brought into continuous or intermittent contact with an ionic compound or an ionic compound solution obtained by dissolving the ionic compound in a solvent. In the dynamic pressure bearing device, the ionic compound is provided in a portion of a bearing or a shaft member and is thus brought into contact with the lubricating oil, in which the ionic compound or ionic compound solution is substantially insoluble in the ester-based lubricating oil.
