Abstract

A diaphragm device comprising: a support member; a flexible membrane supported by the support member; and a housing for accommodating the flexible membrane and the support member, and wherein the flexible membrane will be in a first chamber and a second chamber inside the housing Airtightly separated, the second chamber is connected to the outside via a through hole formed in the film supporting part of the support member, wherein an opening useful for avoiding contact with the through hole is formed at a position corresponding to the through hole in the flexible film. An avoidance recess where edges interfere, wherein the avoidance recess is provided at a thicker portion than other portions of the flexible film, and the thick portion protrudes toward the first chamber.

Description

[0001] Cross-References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2012-039127 filed on Feb. 24, 2012, the subject matter of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a diaphragm device that uses a difference between pressures acting on two surfaces of a flexible membrane (hereinafter, referred to as a pressure difference) to generate a driving force, or that uses a The present disclosure also relates to a pressure regulating reservoir using the diaphragm device for equalizing the pressure of the chamber facing the two surfaces of the flexible membrane. Specifically, the pressure regulation reservoir plays its role in the case of temporarily storing brake fluid that is discharged from the wheel cylinders based on an instruction from an electronic control device in a braking device for a vehicle. Background technique [0004] A conventional ...
