As can be understood from the above description, the gap between the valve plunger 11 and the reaction disk 22 is formed when the pressing force from the other pressurizing device 37 is released while the pressing force from the pressurizing device 36 is maintained. The gap δ corresponds to the gap that allows the reaction force to be transmitted to the input shaft 21 at the moment when the brake reaction force applied to the output shaft 23 reaches the predetermined pressing force. Even if there are variations in the amount of elastic deformation, etc., it is possible to reliably adjust the transmission start timing of the reaction force to a predetermined timing.
