To provide a liquid pressure generator that can surely receive a shaft member which is retuned backward when the device cannot be supplied with electric power during the increase of liquid pressure of a brake, while being suppressed from enlarging in size and increasing in weight.SOLUTION: In a liquid pressure generator, a buffer member 120 that buffers impact generated when a shaft member 25a moves backward and contacts the device is arranged behind the shaft member 25a. A member 130 to be guided for stopping rotation of the shaft member 25a is provided in the shaft member 25a. A groove 141 as a guiding part that guides the member 130 to be guided in an axial direction of the shaft member 25a is provided in a base body 100. The member 130 to be guided has a guided member-side restricting part 161 that restricts rotation of a nut member 25b by contacting a nut side-restricting part 151 provided in the nut member 25b.SELECTED DRAWING: Figure 2

    【課題】大型化および重量増加を抑制しつつ、ブレーキ液圧の昇圧中に電力が得られなくなった場合に後方へ戻されるシャフト部材を確実に受けることができる液圧発生装置を提供する。【解決手段】液圧発生装置において、シャフト部材25aの後方には、該シャフト部材25aが後方へ移動して当接した場合の衝撃を緩和する緩衝部材120が配置されている。そして、シャフト部材25aの回り止めのための被案内部材130がシャフト部材25aに設けられている。シャフト部材25aの軸方向に被案内部材130を案内する案内部としての溝141が基体100に設けられている。被案内部材130は、ナット部材25bに設けられたナット側規制部151に当接してナット部材25bの回転を規制する被案内部材側規制部161を有している。【選択図】図2
