Abstract

A journal bearing device (10) has upper half pads (21) on an upper half bearing section (20) of a bearing supporting a rotating shaft (50), and also has lower half pads (31) on a lower half bearing section (30). The lower half pads (31) are arranged on the inner peripheral surface of the lower half bearing section (30) with intervals in the circumferential direction of the surface. One of the lower half pads (31) is placed at a position perpendicularly below the rotating shaft (50).
