<P>PROBLEM TO BE SOLVED: To provide a bearing device having improved mass-productivity for reducing the abnormal noise of a turbo charger. <P>SOLUTION: The bearing device 2 for the turbo charger 1 is provided between a shaft 13 connecting a compressor rotor 17 to a turbine rotor 14 and a bearing housing 11b encircling the shaft 13. The bearing device 2 comprises a compressor side bearing 25 and a turbine side bearing 26 arranged spaced apart in the axial direction. A spring pin 33 is fitted into each of a compressor side oil supply hole 30 formed in the bearing housing 11b and an oiling hole 25a formed in the compressor side bearing 25 for preventing the rotation of the compressor side bearing 25 around the axis. <P>COPYRIGHT: (C)2007,JPO&INPIT |
