An auxiliary chamber is defined on the outer periphery of the piston on the opposite side to the pressure chamber, and the auxiliary chamber is communicated with the pressure chamber through the axial recess, and the valve stem is arranged in the axial direction. A master cylinder configured to restrict communication between the auxiliary chamber and the pressure chamber between the end of the valve stem and the recess when the master cylinder is inserted into the recess to a predetermined position range.
