PROBLEM TO BE SOLVED: To provide a bearing device that is formed of a sintered alloy, prevents cracking, and reduces effects due to abrasion powder of the sintered alloy. SOLUTION: A sliding bearing 11 is arranged at a connection part 10a or the like forming a joint or the like of a hydraulic shovel so as to freely rotatably hold an unillustrated shaft. The sliding bearing comprises a first divided member 11a, a second divided member 11b, and a third divided member 11c respectively vertically divided and made of an iron-based sintered alloy. A first clearance 13a, a second clearance 13b, and a third clearance 13c are respectively provided between the adjacent divided members 11a-11c. The bearing device includes a housing 12 having a hole 12a into which the sliding bearing 11 is inserted. A first protrusion 12b, a second protrusion 12c, and a third protrusion 12d respectively having a linear shape are provided in the housing 12 so as to form the clearances 13a-13c.
