To provide a bearing structure and a vehicle pedal device easily adjustable to predetermined operation feeling regardless of a variation in a shape of a bush or a pin.SOLUTION: A brake pedal device includes a bearing structure 12A. The bearing structure 12A includes a pedal arm boss 18, a cylindrical bush 20 made of resin, and a caulking pin 50. The bush 20 includes: a first stepped part 32 in which a distance from a shaft to an inner surface 28 becomes shorter from a first length to a second length at a predetermined ratio as the first stepped part 32 advances in a predetermined circumferential direction and then the distance returns from the second length to the first length; and a slot 26 formed through in an axial direction. The caulking pin 50 includes a second stepped part 60 in which a distance from a shaft to a side face 56 becomes shorter from a third length to a fourth length at a predetermined ratio as the second stepped part 60 advances in the predetermined circumferential direction and then the distance returns from the fourth length to the third length. The bush 20 is brought into contact with the boss 18 by a pressing force of the caulking pin 50 rotated in the predetermined circumferential direction.SELECTED DRAWING: Figure 14

    【課題】ブッシュ又はピンの形状にバラツキがあっても、所定の操作フィーリングに調整することが容易な軸受構造及び車両用ペダル装置を提供すること。【解決手段】ブレーキペダル装置は、軸受構造12Aを備える。軸受構造12Aは、ペダルアームのボス18と、円筒形状を有した樹脂製のブッシュ20と、カシメピン50とを備える。ブッシュ20は、軸から内面28までの距離が所定の周方向へ進むに連れて第1長さから第2長さに所定の割合で小さくなった後で第2長さから第1長さに戻る第1段差部32と、軸方向に貫いて形成されたスリット26とを備える。カシメピン50は、軸から側面56までの距離が所定の周方向へ進むに連れて第3長さから第4長さに所定の割合で小さくなった後で第4長さから第3長さに戻る第2段差部60を備える。所定の周方向へ回転されたカシメピン50の押圧によって、ブッシュ20がボス18に接触する。【選択図】図14
