PROBLEM TO BE SOLVED: To provide an electric booster which achieves downsizing.SOLUTION: An electric booster 1 has a first lever member 7 which is disposed spanned between a nut member 106 of a ball screw mechanism 5 and a propulsion member 4 and transits translatory movement of the nut member 106 to the propulsion member 4. In the first lever member 7, a fixed shaft 130 which rotates the first lever member 7 is fixed to a housing 10 between the ball screw mechanism 5 and the propulsion member 4. The structure enables downsizing of the electric booster 1.SELECTED DRAWING: Figure 7 【課題】小型化された電動倍力装置を提供する。【解決手段】電動倍力装置１は、ボールねじ機構５のナット部材１０６と推進部材４とに跨って配置され、ナット部材１０６の直進運動を推進部材４に伝達する第１レバー部材７を有し、該第１レバー部材７は、該第１レバー部材７を回動させる固定シャフト１３０がボールねじ機構５と推進部材４との間で、ハウジング１０に固定される。これにより、電動倍力装置１を小型化することができる。【選択図】図７
