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 constituted of an electric motor that generates first rotative power Tm, a speed reducer that reduces speed of the first rotative power Tm and outputs second rotative power Tn, a rotating member that performs rotational motion and a direct-acting member that performs linear motion, which is provided with: a converting mechanism that converts the second rotative power Tn to linear power Fn of the direct-acting member; a piston that is inserted into a cylinder to adjust liquid pressure Pc in the cylinder by the linear power Fn; and a buffering member that when the electric motor cannot generate the first rotative power Tm, absorbs motion energy of a member to be moved that is moved in a direction along a rotating shaft line Jk of the rotating member by the liquid pressure Pc. The buffering member, arranged at the opposite side of the cylinder with respect to the member to be moved in a direction of the rotating shaft line Jk, absorbs motion energy by colliding with the member to be moved.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を出力する減速機と、回転運動をする回転部材と直線運動をする直動部材とで構成され、第2回転動力Tnを直動部材の直線動力Fnに変換する変換機構と、シリンダ内に挿入され、直線動力Fnによりシリンダの液圧Pcを調整するピストンと、電気モータが第1回転動力Tmを発生できない場合に、液圧Pcにより回転部材の回転軸線Jkに沿った方向に動かされる被移動部材の運動エネルギを吸収する緩衝部材と、を備える。緩衝部材は、回転軸線Jkの方向において、被移動部材に対してシリンダとは反対側に配置され、被移動部材と衝突することにより運動エネルギを吸収する。【選択図】図2
