摘要： An inflator includes a rupturable plate in a circular shape for closing an opening of a pressurized gas-filled space. The rupturable plate has a fragile portion formed by grooves in a regular polygon on one surface, including first fragile portions formed by grooves forming a circumference of the regular polygon, and second fragile portions formed by grooves extending from all apexes of the regular polygon to a center thereof creating a plurality of triangles formed by the first fragile portions as a base and the second fragile portions as the remaining two sides. The depth (h1) of the first fragile portion is less than the depth (h2) of the second fragile portion whereby, when pressure is exerted on a rear surface opposite to the fragile portions, the second fragile portions will rupture as the first fragile portions bend.
