設したことを特徴とするタンデム型ブレーキ倍力装置。The front piston includes two pistons, front and rear, that move forward and backward in response to a pressure difference, a cylindrical member that connects these two pistons, and a pair of diaphragms that are respectively supported by the pistons and partition the inside of the shell. In a tandem brake booster, the piston is fixed to a flange formed at the front end of the cylindrical member, and the inner peripheral edge of the front diaphragm is supported at the base of the flange. an annular recess that can accommodate the inner peripheral edge of the diaphragm is formed on the rear surface thereof, and an inner peripheral end of the front piston is projected into the recess to form a protruding retaining portion; A tandem brake booster characterized in that an engagement groove that engages with this engagement portion is carved.
