To achieve the above object, in the master cylinder reservoir of the present invention in which a diaphragm is interposed between a cap and a body to define an upper chamber communicating with the outside and a lower chamber communicating with a reservoir chamber, and a slit is formed in the diaphragm so that the slit is opened by the deformation of diaphragm caused by the pressure difference acting on the upper and lower surfaces of the diaphragm, by which communication is permitted between the upper and lower chambers, a plate is disposed below the diaphragm in such a manner as to substantially cover the diaphragm, and a vent hole communicating between the upper and lower surfaces of the plate is provided.
