To provide a liquid pressure generator, which is configured so that protection of a constitutive member can be attained during reverse action with a simple structure.SOLUTION: A liquid pressure generator is composed of an electric motor MT that generates first rotative power Tm, a speed reducer GS that reduces speed of the first rotative power Tm and outputs second rotative power Tn, a rotating member BK that performs rotational motion and a direct-acting member BH that performs linear motion, which is provided with: a converting mechanism GH that converts the second rotative power Tn to linear power Fn of the direct-acting member BD; a piston NC that is inserted into a cylinder CC formed in a housing HG holding the speed reducer GS to adjust liquid pressure Pc in the cylinder CC by the linear power Fn; and a disc spring SD arranged at the opposite side of the cylinder CC with respect to the direct-acting member BD in a direction of a rotating shaft line Jk of the rotating member BK. When the electric motor MT cannot generate the first rotative power Tm, the disc spring SD generates spring force for inhibiting movement of the direct-acting member BD that is caused by the liquid pressure Pc.SELECTED DRAWING: Figure 2

    【課題】液圧発生装置において、逆作動時の構成部材の保護を、簡素な構成で達成すること。【解決手段】液圧発生装置は、第1回転動力Tmを発生する電気モータMTと、第1回転動力Tmを減速して第2回転動力Tnを出力する減速機GSと、回転運動をする回転部材BKと直線運動をする直動部材BDとで構成され、第2回転動力Tnを直動部材BDの直線動力Fnに変換する変換機構GHと、減速機GSを保持するハウジングHGに形成されるシリンダCC内に挿入され、直線動力Fnによって、シリンダCC内の液圧Pcを調整するピストンNCと、回転部材BKの回転軸線Jkの方向において、直動部材BDに対して、シリンダCCとは反対側に配置される皿ばねSDと、を備える。皿ばねSDは、電気モータMTが第1回転動力Tmを発生できない場合に、液圧Pcにより生じる直動部材BDの動きを阻止するばね力を発生する。【選択図】図2
