PROBLEM TO BE SOLVED: To provide a bearing device capable of saving costs, an installation space, energy and resource, securing the sufficient oiling amount from low-rev thrust to high-rev thrust and over an extended time, and obtaining high reliability. SOLUTION: An oiler 24 supplying lubricant 11 to a journal bearing 2 contains a disk 19 fixed on a rotary shaft, an oil case 20 forming an arc-shaped shallow oil chamber 21 opposing the disk 19, an oil suction passage 27 for leading the lubricant 11, and an oil supply passage 26 leading the lubricant 11 to the journal bearing 2. The oil case 20 has heat resistance, and consists of a synthetic resin having self-lubricity.
