PROBLEM TO BE SOLVED: To provide a bearing bush which can prevent the lowering of an operation feeling and the generation of noise resulting from wobbling in a radial direction, and a pedal device having the bearing bush.SOLUTION: A bearing bush 1 comprises: a cylindrical part 6 having a cylindrical inner face 2 and a cylindrical outer face 3; a cylindrical part 14 having a cylindrical inner face 9 and a cylindrical outer face 10; a swollen part 22 having a curved protrusive outer face 20 which is located inside a radial direction Y rather than the cylindrical outer faces 3, 10 at both ends 18, 19 in an axial direction X, and on the other hand, located outside the radial direction Y rather than the cylindrical outer faces 3, 10 between both the ends 18, 19 in the axial direction X, and a curved recessed inner face 21 which is curved while complementarily responding to the curved protrusive outer face 20: and a slit 29 which makes the cylindrical parts 6, 14 and the swollen part 22 contractive in diameters.SELECTED DRAWING: Figure 1
