<P>PROBLEM TO BE SOLVED: To realize smooth and stable rotation of a turbocharger by accurately managing positioning of an outer ring of a rolling bearing. <P>SOLUTION: In a bearing structure of the turbocharger 100, angular rolling bearings 20, 21 are respectively mounted to a turbine side and a compressor side of a rotation shaft 50, and a single collar member 30 is arranged between outer rings 22, 23 of the rolling bearings 20, 21. The outer rings 22, 23 are loosely fitted to holding parts 37, 38 of the collar member 30. The holding parts 37, 38 hold the outer rings 22, 23 movably in the axial direction. Lubrication oil supplying holes 35, 36 for supplying lubrication oil to end surfaces 22A, 23A of the outer rings 22, 23 are formed in the holding parts 37, 38 along the axial direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
