PROBLEM TO BE SOLVED: To alleviate occurrence of noise and an impact feeling by suppressing rattling and tilting of a boss caused by a gap at each part while securing support rigidity of the boss.SOLUTION: A cylindrical part 46 of flanged bushes 42, 44 are press-fitted to a boss 40, and by an annular projection part 50 and a taper-shaped flange part 48, a gap between the cylindrical part 46 and a collar 26 and a gap between the flange part 48 of the flanged bushes 42, 44 and support plates 20, 22 can be eliminated while securing assembly workability for both cases. Thus, tilting and rattling of the boss 40 during a stepping operation of a brake pedal 12 are suppressed, and occurrence of noise and an impact feeling are alleviated. Also, as the flange part 48 is connected in a circumferential direction across the whole periphery, support rigidity of the boss 40 is properly secured irrespective of a deflection deformation of a flange part side end part, a posture of the brake pedal 12 supported rotatably via the boss 40 is stabilized, and an operation feeling at the stepping operation time improves.

    【課題】ボスの支持剛性を確保しつつ各部の隙間に起因するボスのがたつきや傾動を抑制して異音の発生や衝撃感を緩和する。【解決手段】鍔付きブッシュ42、44の円筒部46がボス40に圧入されるとともに、環状突出部50やテーパ形状の鍔部48により、円筒部46とカラー26との間の隙間、鍔付きブッシュ42、44の鍔部48とサポートプレート20、22との間の隙間を、何れも組付作業性を確保しつつ無くすことができるため、ブレーキペダル12の踏込み操作時におけるボス40の傾動やがたつきが抑制されて、異音の発生や衝撃感が緩和される。また、鍔部48が全周に亘って周方向に繋がっているため、鍔部側端部の撓み変形に拘らずボス40の支持剛性が適切に確保され、そのボス40を介して回動可能に支持されているブレーキペダル12の姿勢が安定し、踏込み操作時の操作フィーリングが向上する。【選択図】図2
