ーキ倍力装置。[Claims for Utility Model Registration] (1) A diaphragm plate and each inner peripheral edge of the diaphragm along the back surface of the diaphragm are integrally and tightly fitted into the outer peripheral part of the valve body, and the outer peripheral edge of the diaphragm is fitted into a shell. Assemble airtightly,
The inside of the shell is divided into a constant pressure chamber and a variable pressure chamber, and the constant pressure chamber is connected to a negative pressure source, and atmospheric air is supplied and exhausted to the variable pressure chamber via a valve mechanism, and the differential pressure applied to the diaphragm acts as a booster. In the brake booster for performing this, a flange is provided at the portion of the diaphragm plate that fits tightly into the valve body, and a claw portion formed by cutting and raising a part of the diaphragm plate is bent and fixed to the flange. A brake booster characterized by: (2) The diaphragm plate has a cylindrical portion parallel to the circumferential surface of the valve body on its inner peripheral edge, and a retaining portion is bent at the tip of the cylindrical portion in a direction perpendicular to the cylindrical portion. The brake booster according to claim 1, wherein the retaining portion is surrounded by and integrated with a bead portion formed on the inner peripheral portion of the diaphragm.
