PROBLEM TO BE SOLVED: To provide a bush bearing which can be easily pressed into a press-in hole without crushing an opening end and without generating metal chips when pressing into a hole of a housing and which can secure circularity of the inner peripheral surface after press-in. SOLUTION: This bush bearing 1 is formed of a roll bush bearing provided with a cylindrical inner peripheral surface 2 formed into a sliding surface and a peripheral surface 3 so that they abut on each other in abutting surfaces 4. The peripheral surface 3 is provided with a cylindrical surface 11, a tapered surface 13 interposed between the cylindrical surface 11 and one annular end surface 12 in the axial direction X and formed by forming a roll, a smooth arc surface 14 interposed between the tapered surface 13 and the cylindrical surface 11, and a smooth arc surface 15 interposed between the tapered surface 13 and the end surface 12.
