構成したことを特徴とする倍力装置。 a rear shell made of a metal plate having a flange portion extending radially outward; and a front shell made of a metal plate having a stepped cylindrical portion accommodating the flange portion of the rear shell; is fitted into the cylindrical portion of the front shell, the outer peripheral bead portion of the diaphragm is airtightly sandwiched between the two shells, and a plurality of locking pawls provided on the cylindrical portion of the front shell are fitted. In the booster which connects the two shells by engaging with the outer surface of the flange portion of the rear shell, the cylindrical portion on the large diameter side of the front shell is heated along the circumference of the cylindrical portion in the axial direction of the central portion thereof. The locking is achieved by forming a plurality of holes whose width is larger than the axial width of both ends thereof, and by bending inward the large-diameter cylindrical portion of the front shell that is closer to the open end than the holes. A booster characterized by comprising a claw.
