Claims

[Claims for Utility Model Registration] An actuator shell comprising a pair of bowl-shaped shells having a space into which negative pressure can be introduced, and a diaphragm sandwiched between flanges formed on the outer edges of both shells, A plurality of notches are provided on the outer edge of the flange of one shell, and a plurality of locking protrusions are formed on the remaining outer edge toward the opening side toward the center, and at the same time, on the outer edge of the flange of the other shell. A claw part that fits into the notch part is provided, and an outer edge part other than the claw part is formed to be locked with the locking protrusion, and each part formed on both shells is fitted into each other. An actuator shell, characterized in that the two shells are attached and locked to each other, and a fastening band is attached to cover the outer periphery of the coupling portion.
