At the same time, the rear end surface of the pressing part in the axial direction is used as a reference abutment surface, and a supporting part for supporting the outer peripheral bead of the diaphragm is formed on the outer periphery of the rear shell. The side is raised radially outward to form a contact portion that contacts the reference contact surface, and the outer peripheral bead portion of the diaphragm supported by the support portion is fitted into the small diameter cylindrical portion to make the contact. The front end surface of the section is brought into contact with the reference contact surface, and a part of the large-diameter cylindrical section is pressed and deformed from the outside of the cylindrical section of the front shell inward to form the contact section of the rear shell. A shell connection structure in a booster, characterized in that a protruding engaging claw is formed to support a rear end surface.
