    • PROBLEM TO BE SOLVED: To provide a rolling bearing device in which a fitting gap between the outer peripheral surface of a sleeve and the inner peripheral cylindrical surface of a housing is precisely adjusted to a predetermined fitting gap and the lowering of the rigidity is hard to occur when the outer peripheral surface of the sleeve is increased in diameter. SOLUTION: In the second sleeve 13 fitted into the inner peripheral surface of the housing, the outer peripheral surface of the front end part of the fitting part of the second sleeve 13 is positioned radially inward more than the extension surface 213 of the outer peripheral cylindrical surface 207 of the base part 200 of the second sleeve 13. The inner peripheral surface of the front end part of the fitting part of the second sleeve 13 is positioned radially inward more than the extension surface 214 of the inner peripheral conical surface 208 of the base part 200 of the second sleeve 13.

    • PROBLEM TO BE SOLVED: To provide a supercharger capable of preventing seizure of a roller bearing by forming it in such structure as providing a cooling effect and supplying an appropriate quantity of lubricant without containing foreign matter.
      SOLUTION: This supercharger includes a housing 40 and a turbine shaft 41 supported by the center hole 43 in the housing 40 through rolling bearings 10a and 10b. A cooling water jacket 26 in the housing 40 is arranged in the main body portion 40a of the housing 40. The rolling bearings 10a and 10b are supplied with lubricant by a tank portion 35 formed in the housing 40 for reserving the lubricant and a wick member 36 arranged between the tank portion 35 and the center hole 43. The wick member 36 includes a core portion 37 composed of a fiber portion 37a and gaps 37b. The lubricant is supplied by the capillary action of the gaps 37b. The porosity of the gaps is set not smaller than 45.5% and smaller than 80%.
