PROBLEM TO BE SOLVED: To provide a fluid pressure generator that can improve layout performance in the case of using an endless transmission member.SOLUTION: A fluid pressure generator 1 that can generate brake fluid pressure by moving a second piston 32 by driving an electric motor 61 comprises a substrate 10 to which the electric motor 61 is fixed. The fluid pressure generator 1 comprises: a driving-side pulley 62 which connects to a rotary shaft 61b of the electric motor 61; and an output member 63 which has a center shaft L2 parallel to a center shaft L4 of the driving-side pulley 62 and drives the second piston 32 in interlock with the driving-side pulley 62. Across the driving-side pulley 62 and the output member 63 is hung a belt 64. Further the fluid pressure generator 1 comprises bearing members 71a and 71b which bear the output member 63 rotatably relative to the substrate 10. The belt 64 is arranged to overlap with at least parts of the bearing members 71a and 71b when viewed from a direction perpendicular to the center shaft L2.SELECTED DRAWING: Figure 6
【課題】無端状の伝達部材を用いる場合においてレイアウト性を向上させることができる液圧発生装置を提供する。【解決手段】電動モータ61の駆動によって第二ピストン32を移動させてブレーキ液圧を発生可能な液圧発生装置1は、電動モータ61が固定される基体10を備える。この液圧発生装置1は、電動モータ61の回転軸61bに接続する駆動側プーリ62と、駆動側プーリ62の中心軸L4に平行な中心軸L2を有するとともに駆動側プーリ62に連動して第二ピストン32を駆動させる出力部材63と、を備える。駆動側プーリ62と出力部材63とには、ベルト64が架け渡されている。液圧発生装置1は、出力部材63を基体10に対して回転可能に支持する軸受部材71a,71bを備え、ベルト64は、軸受部材71a,71bの少なくとも一部と中心軸L2に垂直な方向から見て重ねて配置されている。【選択図】図6
