<P>PROBLEM TO BE SOLVED: To prevent rotational vibration transmission and suppress a noise even when an oil film is not sufficiently formed in a structure with no durability problem. <P>SOLUTION: A bearing structure of a turbocharger using a rolling bearing has a bearing holder (oil film damper) 30 which holds outer rings of a pair of bearings 20 and 21 and is supported in a floating state via a bearing housing 10 and a clearance b for forming an oil film. The bearing holder 30 includes a flange portion 60, and the flange portion 60 is inserted and fixed to the bearing housing 10 in order to prevent shaft misalignment of the bearing holder 30. Then, elastic portions 61 and 62 with flexibility in a radial direction are formed on both sides of the flange portion 60. <P>COPYRIGHT: (C)2010,JPO&INPIT |
