PROBLEM TO BE SOLVED: To prevent generation of abnormal noise caused by vibration of a return coil spring interposed between a booster body and an input rod and disposed in a cabin.SOLUTION: A brake booster 100 includes a vibration proof member A at an end 31 of a return coil spring 30 which is interposed between a booster body 10 and an input rod 20 and disposed in a cabin. The vibration proof member A includes: a sheet section 41 which is interposed between the end 31 of the return coil spring 30 and a support section 10a1 for supporting the end 31 so as to suppress vibration of the return coil spring 30; and a guide section 42 which is provided integrally with the sheet section 41 and is fitted into an inner periphery of the end 31 of the return coil spring 30 with a prescribed radial direction interference.SELECTED DRAWING: Figure 1

    【課題】ブースタボディと入力ロッド間に介装されて車室内に配置されるリターンコイルスプリングの振動に起因する異音の発生を防止すること。【解決手段】ブレーキ倍力装置100では、ブースタボディ10と入力ロッド20間に介装されて車室内に配置されるリターンコイルスプリング30の端部31に防振部材Aが設けられている。防振部材Aには、リターンコイルスプリング30の端部31と同端部を支持する支持部10a1間に介在してリターンコイルスプリング30の振動を抑制するシート部41と、シート部41に一体的に設けられていてリターンコイルスプリング30の端部31内周に所定の径方向締め代をもって嵌合するガイド部42が設けられている。【選択図】 図1
