PROBLEM TO BE SOLVED: To suppress the generation of wobbling and noise resulting from a clearance between parts, in a bearing part structure of a vehicle pedal device in which a bush is arranged between a collar and a boss.SOLUTION: Cylindrical parts 46 of collared bushes 42, 44 comprise a plurality of irregular divided parts 52 which are extended in cantilever shapes from a complete cylinder part 50 which is arranged at one end part in an axial direction. The irregular divided parts 52 have protrusions 58 which closely adhere to an internal peripheral face 40f of a boss 40, and recesses 56 which closely adhere to an external peripheral face 26f of a collar 26. The irregular divided parts are deflection-deformed between the boss 40 and the collar 26. By this constitution, a variation of a clearance between the collar 26 and the boss 40, and a change of the clearance at a pedal operation are absorbed by the deflection-deformation of the plurality of the irregular divided parts 52, the support rigidity of the boss 40 is secured by a reaction force generated by the deflection deformation, displacement in a radial direction is suppressed, and the generation of the wobbling and noise of a brake pedal 12 is suppressed.SELECTED DRAWING: Figure 5 |
