Abstract
A diaphragm assembly is designed to follow a drop in the level of a working fluid filled in a reservoir used with a master cylinder for the purpose of cutting off the communication between the working fluid and the outside air. The diaphragm includes a pair of opposite lower steps in the axial direction. Each of the steps comprises an upright flat portion and an upper flat portion which form parts of the bottom wall and side wall of the diaphragm, when the level of the working fluid in the reservoir reaches a predetermined lower limit. The upper flat portions of the steps are inclined to at a given angle to the horizontal, thus forming an air passage.
