摘要:
Provided are: a lubricating device for a bearing; and an exhaust turbosupercharger, wherein a bearing device (36) is provided with a housing (15) with a hollow shape, and journal bearings (21, 22) which rotatably support a rotary shaft (14) arranged inside the housing (15), the bearing device (36) being further provided with: a third feeding passage (43) and a fourth feeding passage (44) through which lubricant is fed toward outer circumferential surfaces (21b, 22b) of the journal bearings (21, 22); a sixth feeding passage (46) through which lubricant is fed toward a space section (16A) between the journal bearings (21, 22); and a guide section which guides, toward inner circumferential surfaces (21c, 22c) of the journal bearings (21, 22), the lubricant fed from the sixth feeding passage (46) to the space section (16A).
