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
【課題】カラーとボスとの間にブッシュが配設される車両用ペダル装置の軸受部構造において、各部の隙間に起因するがたつきや異音の発生が抑制されるようにする。【解決手段】鍔付きブッシュ42、44の円筒状部46が、軸方向の一端部に設けられた完全円筒部50から片持ち状に延び出す複数の凹凸状分割部52を備えており、その凹凸状分割部52は、ボス40の内周面40fに密着させられる凸部58とカラー26の外周面26fに密着させられる凹部56とを有し、そのボス40とカラー26との間で撓み変形させられる。このため、カラー26とボス40との間のクリアランスのばらつきや、ペダル操作時のクリアランスの変化が、複数の凹凸状分割部52の撓み変形によって吸収されるとともに、その撓み変形による反力でボス40の支持剛性が確保されて径方向の変位が抑制され、ブレーキペダル12のがたつきや異音の発生が抑制される。【選択図】図5
