PROBLEM TO BE SOLVED: To properly reduce the axial-direction loosening of a boss of a pedal for a vehicle for a long period of time while suppressing an increase in turning resistance, in a bearing part structure in which the boss of the pedal for a vehicle is arranged in a support member via bushes with flanges.SOLUTION: In a use state in which a boss 40 is arranged in a collar 26 via bushes 42, 44 with flanges, since the boss 40 is downwardly displaced according to play A between the collar 26 and itself by the own weight of a brake pedal 12, play B between recessed tapered faces 50 of pedal supports 20, 22 and protruded tapered faces 52 of flanges 48 becomes small, and the axial-direction loosening of the boss 40 is reduced while suppressing an increase in turning resistance. Even if the flanges 48 are pressed by the pedal support 20 or 22 by the pedal-in operation of the brake pedal 12, the tapered faces 50, 52 are pressed to each other in a state of being slightly decentered, its contact area is comparatively large, the friction or the like of the flanges 48 is suppressed, and a loosening reduction effect can be properly maintained. |
