PROBLEM TO BE SOLVED: To provide a floating bearing structure for suppressing the occurrence of whirling vibration. SOLUTION: A turbocharger 1 comprises a shaft extending in one direction, a cylindrical floating bush 24 encircling the shaft 7 and having an inner peripheral face opposed to the outer peripheral face of the shaft 7, and a center housing 36 having an internal space for storing the floating bush 24. The floating bush 24 has a through-hole 124 passing through the bush in a range from the outer peripheral face to the inner peripheral face in the radial direction. The center housing 36 has a first oil supply passage 136 for supplying oil 100 to the through-hole, and three or more second oil supply passages 236. The second oil supply passages 236 are arranged at mutual spaces in the circumferential direction of the outer peripheral face. COPYRIGHT: (C)2009,JPO&INPIT |
