[Problem] To obtain a good pedal feeling by starting operation of a stroke simulation function more smoothly, and to form a compact stroke simulator. [Solution] A pedal feeling simulator unit (3), which serves as a stroke simulator, comprises: an input shaft (4) that undergoes a stroke movement upon addition of an input; a simulator operation piston (14) that undergoes a stroke movement due to the stroke of the input shaft (4); a simulator operation liquid pressure chamber (15) in which, due to the stroke of the simulator operation piston (14), a simulator operation liquid pressure is generated such that a reaction force based on the stroke of the input shaft (4) is added to the simulator operation piston (14); and a liquid pressure operation control device (28) that controls the simulator operation liquid pressure on the basis of the stroke of the input shaft (4) by controlling supply and discharge of the operation liquid to and from the simulator operation liquid pressure chamber (15). |
