<p><P>PROBLEM TO BE SOLVED: To provide an inflater having a compact and lightweight structure with high safety at storage and transportation. <P>SOLUTION: The inflater 1 includes: a cylinder 2 filled with a high pressure gas at the inside and having a gas release port 2a on an axis; a rupture disc 3 for closing the gas release port; an igniter 4; a flowing out passage 5 for forming a route of the high pressure gas; and an adapter 9 detachably mounted to a distal end of the flowing out passage 5. The flowing out passage 5 is a cylinder extended in an axial direction relative to the cylinder 2, opened in an axial direction, and having one or both of a recess and a projection, and further has a male screw part 8 having a smaller outer diameter than the maximum outer diameter of the cylinder at a distal end part. The adapter 9 has a nut part 9a having a female screw part at an inner side and a hollow dome part 9b, and has a plurality of holes 9c penetrated to a direction perpendicular to the axis in the dome part 9b in symmetrical to each other. The female screw part of the adapter is engaged with the male screw part at the distal end part of the flowing out passage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
