PROBLEM TO BE SOLVED: To provide a braking device capable of improving a brake operation feeling.SOLUTION: A braking device comprises: a stroke simulator 5 having a piston 52 which is operable in a cylinder 50 in an axial direction by a brake fluid supplied from a master cylinder 3, partitions the inside of the cylinder 50 into at least a normal pressure chamber and a back pressure chamber 512 and has a pressure receiving area facing the back pressure chamber 512 smaller than that facing the normal pressure chamber, and generating a reaction force of manipulation accompanying the brake operation of a driver by operation of the piston 52; a second oil path 12 provided between the normal pressure chamber and the master cylinder 3; a third oil path 13 connecting the first oil path and the back pressure chamber 512; a fourth oil path 14 connecting the back pressure chamber 512 and a reservoir tank 4; and switching parts 23, 24 switching connection of the back pressure chamber 512 to the first oil path or the reservoir tank 4.SELECTED DRAWING: Figure 1
【課題】ブレーキ操作フィーリングを向上することができるブレーキ装置を提供すること。【解決手段】マスタシリンダ3から供給されたブレーキ液によりシリンダ50内を軸方向に作動可能であって、シリンダ50内を少なくとも正圧室と背圧室512に画成し、背圧室512に臨む受圧面積が正圧室に臨む受圧面積よりも小さいピストン52を有し、ピストン52が作動することで運転者のブレーキ操作に伴う操作反力を生成するストロークシミュレータ5と、正圧室とマスタシリンダ3との間に設けられた第2油路12と、背圧室512と第1油路との間を接続する第3油路13と、背圧室512とリザーバタンク4との間を接続する第4油路14と、背圧室512と第1油路又はリザーバタンク4との接続を切り替える切替え部23,24とを備えた。【選択図】図1
