PROBLEM TO BE SOLVED: To provide a hydraulic braking device in which characteristics of change of hydraulic pressure, for example, in a master cylinder with respect to a brake operation can be variably set.SOLUTION: The hydraulic braking device includes: a cylinder; a piston which is housed in the cylinder so as to be able to reciprocate and moves from one side position in a reciprocation direction to the other side by an input of brake pedal depression force corresponding to an operation of a brake pedal and an input by means of liquid flowing-in from a fluid supply source to a first fluid chamber formed between an inner wall surface of the cylinder and the piston and, thereby, generates a hydraulic pressure for generating a braking force; and a reaction force mechanism which adds a reaction force directing to one side, to the piston moving from one side to the other side by means of an elastic member which is elastically deformed by liquid flowing-in from a liquid supply source to a second fluid chamber formed on the other side in the cylinder. The reaction mechanism includes an adjusting member which adjusts flow rate of liquid flowing-in from a fluid supply source to the second fluid chamber.
【課題】例えば、ブレーキ操作に対するマスタシリンダ内の液圧の変化特性を可変的に設定することが可能な液圧制動装置を得る。【解決手段】液圧制動装置は、シリンダと、シリンダに往復移動可能に収容され、ブレーキペダルの操作に対応するブレーキ踏力の入力と、シリンダの内壁面との間に形成された第1流体室に流体供給源から流入する液体による入力とによって、往復移動方向の一方側の位置から他方側へ動くことにより、制動力を発生させるための液圧を発生するピストンと、シリンダにおいて他方側に形成された第2流体室に流体供給源から流入する液体によって弾性変形する弾性部材によって、一方側から他方側に動くピストンに一方側に向く反力を付加する反力機構と、を含み、反力機構は、流体供給源から第2流体室に流入する液体の流量を調整する調整部材を含む。【選択図】図2
