A bearing structure (7) is provided with: a bearing holder (18) affixed to the inside of a bearing housing (2) and having a hollow body section (18a) and an oil hole (18f) which passes from the outer peripheral surface (18e) of the body section to the inner peripheral surface (18b) thereof and which conducts lubricating oil to the inside of the body section (18a); two pieces of full floating metal (19, 19) configured such that, within the bearing holder (18), the two pieces of full floating metal (19, 19) are arranged at a distance from each other in the axial direction of a shaft (8) and support the shaft (8); two thrust bearing surfaces (20b, 21b) respectively arranged outside the two pieces of full floating metal (19, 19) in the axial direction of the shaft (8); and two collar sections (22, 23) respectively arranged outside the two thrust bearing surfaces (20b, 21b) in the axial direction of the shaft (8) and provided to the shaft (8). The lubricating oil lubricates the thrust bearing surfaces (20b, 21b) after lubricating the full floating metal (19, 19). |
