Abstract

The metal assembled body is to be disposed in such a manner as to be in contact with a housing space for housing a predetermined compressed gas, and comprises: a first member formed by forging a predetermined metal material, the member including, formed as a single body from the predetermined metal material, a cylindrical peripheral wall section comprising a metal flow from the predetermined metal material formed along the axial direction, and an extending section having an opening and extending from the peripheral wall section in a direction that is different from the axial direction of the peripheral wall section; and a blocking member welded against a ring-shaped welding surface on the extending section in such a manner as to plug the opening. The extending section is formed in such a manner that, in the state prior to the blocking member being welded thereon, an end section of the metal flow from the predetermined metal material is exposed on the welding surface. A region formed by a division of the welding surface by the site of welding with the blocking member wherein the reach of the predetermined compressed gas from the housing space is inhibited, is defined as a first region, and the width of the first region is larger than the width of the region of the welding surface excluding the first region. Such a constitution can suppress the outflow of the compressed gas as much as possible and maintain a suitable sealed state.

Description

technical field [0001] The present invention relates to a metal assembly disposed so as to be in contact with a storage space containing a predetermined pressurized gas. Background technique [0002] For example, in the gas generator disclosed in Patent Document 1, a configuration is adopted in which the combustion gas generated by the operation of the igniter is output by activating the igniter while the pressurized gas is stored in the storage space. , and the contained high-pressure gas. If the contained high-pressure gas flows out over time, it may be difficult to produce the desired gas output when the igniter is operated. Therefore, in order to improve the quality of the product, when storing the pressurized gas in the storage space defined by the metal formed product, it is necessary to pay sufficient attention to the sealing state of the pressurized gas. [0003] A metal-worked molded product that accommodates pressurized gas is usually formed from a block-shaped b...
